Abstract: The present research aimed to study two invertebrate speciesAmphibalanus amphitrite (Darwin, 1854) and Namalycastis indica(Southern, 1921) in two stations along Shatt Al - Arab River in Basrahprovince, southern Iraq. Two stations were selected for this purpose,these two stations were affected by the tidal phenomenon, namely Abu - Alkhaseeb and Karmat Ali.The samples were collected monthly for the period from October 2015 - September 2016. Environmental factors represented by the temperature(air and water), salinity, pH and dissolved oxygen and biological oxygendemand, calcium and nitrates as well as knowledge of soil tissues weremeasured. Samples of the animals were collected by five replicates inAbu - Alkhaseeb station and four replicates in the Karmat Ali station, thenisolated and washed with running water and preserved in numbered plastic bags and were classified based on the taxonomic keys. The total densities of the two animals were detected in addition to the density in the vertical distribution. The statistical evidence was used to find out the differences in the density. Population sizes of the two animals were study and divided into volumetric categories, the process of separating generations was conducted by using probability graph paper to get the true age of the animal as well as study for each class to learn biomass and secondary production.The results of the environmental factors showed that the ranges of parameters as following : air temperature 13.5 - 41.4 °C and water temperature 11.8 - 34.9° at Abu Al - Khaseeb station; air temperature 11.3 - 45 °C, water temperature 10 - 37 °C at Karma Station, pH 6.9 - 8.8 at Abu Al - Khaseeb station and 7.14 - 8.5 at Karma station, salinity 4.22 - 6.6 ppt at Abu Al - Khaseeb station and in Karma station 5 - 7.1 ppt. For dissolved oxygen 6.2 - 11.1 mg/L at Abu Al - Khaseeb station and at Karma station 6 - 12.4 mg/L, biological oxygen demand 1.58 - 4.02 mg/L at Abu Al - Khaseeb station and 2.04 - 5.88 mg/L at Karma station, calcium concentration at Abu Al - Khaseeb station was 160 - 175 mg/L and Karma station 160 - 190 mg/L, nitrate concentration 13.9 - 15.6 mg/L, 14.2 - 17 mg/L at Abu Al - Khaseeb and Karma stations respectively. And tissues of soil were silty clay Abu Al - Khaseeb station and loamy clay in Karma Ali station.The monthly density of each animal was calculated at each station. For barnacle the highest percentage was 2740 individuals/m2 recorded in April 2016 at Abu Al - Khaseeb, the highest percentage in the Karma station was 890 individuals/m2 recorded in October 2015, and for worms was an average of 70 individuals/m2 and 184 individuals/m2 recorded in October and November at Abu Al - Khaseeb and Karma stations respectively. The structure of population sizes was also studied to determine the changes in the population. To illustrate this, it was divided into six categories of barnacle and seven categories of worms.The study examined the of length - weight relationships (dry, ash and organic matter) and to study the total biomass content and the volume groups of each generation of the two populations by multiplying the density of individual/m2 for each generation by dry weight, ash and organic matter. Abu Al - Khaseeb had H generation 7.27 g/m2 dry weight, 5.30 g/m2 for ash weight and 1.63 g/m2 for organic matter, H generation in Karma was the highest mass of 2.338 g/m2 for dry weight and 1.694 g/m2 for ash weight and 0.527 g/m2 for organic matter.The monthly biomass B g/m2 was calculated from adding of the biomasses for each generation and the average (B) of the biomass was derived from divided the sum of the biomass for the months of the year on total sampling month. Total annual secondary production was calculated for each generation of population groups in terms of dry weight, ash and organic matter using the method which summarized in the calculation of density average multiplied by the difference in weight.The highest value of barnacle at Abu Al - Khaseeb was 14.5367 g/m2 for ash weight and 4.536 g/m2 for organic matter, for worms were 2.228 g/m2 for ash and 2.8397 g/m2. In the Karmat Ali, the barnacle had 5.800 g/m2 of ash and 1.0794 g/m2 of organic matter, the worms had 7.583 g/m2 for ash and 9.2845 g/m2 for organic matter.The rate of growth of the two animals was detected by finding the average length of each generation of the population groups per month for each animal. In order to achieve a curate result on the age of the animal in the field and the calculation of its productivity it was necessary to conduct the process of separation of the generations of the population group and therefore used the Probability graph paper method, thepopulation of both studied animals is polymodel.

Abstract: The present study, investigated the reproductive cycle of freshwater prawn, Macrobrachium nipponense during period from December 2015 to November 2016 at Al - Masshab River, Southern of East Al - Hammar Marsh/ Basrah. The water temperature, salinity, pH, dissolve oxygen and turbidity were recorded, the maximum average for water temperature was 28 ºC recorded in July, while the minimum was 12 ºC in January. Water salinity was fluctuation between 0.8 - 2 ppt. in April and November respectively. pH values ware recorded between 7 - 7.6 during all study months. The minimum of oxygen concentration was 5.5 mg/ L in July and the maximum 8.29 mg/ L in the December. Also there are some changes in turbidity of water, the lower was 15.3 NTU in February and the highest was 40.1 NTU in the April. The results of length groups showed, occurrence of group between 44 - 35 mm for females and between 54 - 36 mm for males. The minimum length for females was 48.3 mm in November, and for males was 52.1 mm in November. While themaximum length for females and males were 69.1 mm and 74.7 mm in September and August respectively. The minimum average of weight was recorded in the November for females and males ( 1.6 and 2.0 ) gm respectively, while the maximum average was 4.3 gm for females in September and 4.5 gm for males in August. The total carapace length for females between ( 19.3 - 32.5 ) mm in November and September respectively , and for males was between 21.0 - 31.6 mm for the same period. Length - weight parameters (a and b) of the equation : W = aLb were estimated for M. nipponense , positive correlation ( r= 0.67) for females and ( r= 0.90 ) for males, while the relationship between carapace length and total length were (r = 74) for females and (r = 0.85) for males. Additional to relationship between carapace length and body weight were (r= 62) for females and (r = 0.75) for males. The highest Gonadosomatic Index (GSI) was 10.6 recorded in September, and the lower was 2.7 recorded in July. In this study we observed two peaks for reproductive, the first in Jun. and second in the August. The best percentage for ovigorous was recorded in August 98.7 % whereas, percentage of the non ovigorous in this month was 1.3 % .The condition factor for females was changed between 1.1 during November and 2.10 during September. While for males was between 1.3 to 2.9 during November and August respectively. The seasonal variations in the sex ratio of prawn was different according reproductive cycle, and there was more females than males during reproductive period. The minimum was 1 : 0.17 ( male / female) in February and the maximum percentage was 1 : 9.00 ( male / female) in the Jun. The overall fecundity of 307 ovigorous female of M. nipponense was calculated, the Absolute fecundity ranged from (799 - 2047) egg/ individual, while the relative fecundity between (208 - 578) egg/ gm. The correlations of fecundity with total length and fecundity with body weight were positive for both, it were r= 94 and r= 0.90 respectively. Additional, the eggs had been classified into four stages, based on the external morphological characters such as colour ,size and histological. Egg dimensions varied between 675 + 28 to 763 + 31 μm.

The species constituted 48.3% of the total catch. Fish group size 9.0 - 9.9 cm was dominated in the samples (19.7%).The length - weight relationships of A. mossulensis for immature, female and male were : W = 0.003 L3.087 , W = 0.002 L3.193 , W = 0.004 L3.027respectively, revealing an isometric growth for immature and males, and allometric growth for females. The relative condition factor ranged from 0.71 in June to 1.44 in February with total average of 1.05 for immature, and from 0.78 in August to 1.40 in January with total average of 1.06 for females, and from 0.7 in August to 1.24 in January with total average of 0.99 for males. Four age groups were recorded and the most abundant age group was the second. The relation between total length (L) and scale radius (S) was : L =2.549 + 4.825 S. The lengths of fish during the first four years were 8.15, 11.33, 13.55 and 16.0 cm respectively. The growth performance index of A. mossulensis was computed as 2.16. The growth was described by von Bertalanffy equation as Lt = 20.4(1 - e - 0.35(t+0.277)).Feeding activity values ranged from60.53 % in February to87.7 % in September. The minimum value of feeding intensity was 6.08 points/ fish in December and the maximum value was 8.7 points/ fish in July. Insects comprised 41.2% of the total food items of A. mossulensis followed by algae 28.7%, crustacean 15.9%, diatoms 12.36%, aquatic plants 3.74%, fish 3.36% and Mollusca 0.3%. Fish was found omnivores, tends to animal food more than plant food. The mean value of Lm50 was estimated to be 8.0cm, corresponding to one years old for both sexes. The overall sex ratio was (1 : 1.7 male : female). Gonadosomatic index for females ranged from 0.8 and 0.6 in June for females and males respectively to 14.01 and 5.8 in January for both sexes respectively. The spawning period started in February according to GSI values and histological examination for gonads during spawning season. The results of histological examinations revealed that this species has a short spawning season and female ovaries contained different maturing stages of ova, and the maturation started from the post part of gonads according to the space noticed at the middle part of the ovary. Histological examination proved that testes also contain different maturation stages. Blood vessel penetrate lobules with few spermatocytes at the posterior part of the testes whereas the anterior part less mature with disappearing of spermatocytes. Absolute fecundity for A. mossulensis ranged from1119 eggs for fish of 10.4 Cm length to 5022 egg for female of 14.2 Cm length.The relation between the total length (L) and fecundity represented by the following equation : F = 0.148L3.939 , r2 = 0.605

Abstract: The current study was carried out during the period from December 2015 and June 2016 to assess the chemical composition, fatty and amino acids and the total bacterial count of the muscular tissue from the common carp Cyprinus carpio L. in Basrah city which were cached from Shatt Al - Arab river at Abul - Khasib, obtained from earthen ponds at the University of Basrah, fish cages in Shatt Al - Arab river at Al - Hartha district and those imported from Iran Republic which were available in the domestic markets of Basrah city.The results of the study were statistically analyzed using CRD design applying SPSS statistical package ver. 17 on 50 fish from each source with 3 replicates per sample and the studied factors were tested using RLSD test at 0.05 probability level.The results of the statistical analysis indicated no significant differences (p>0.05) in moisture content between Shatt Al - Arab samples, imported samples, iced pond fish and iced cage fish. No significant differences (p>0.05) were detected also between fish from ponds and cages. Significant differences (p<0.05) were detected between fresh fish from ponds and cages with fresh and iced fish from Shatt Al - Arab or imported fish. The highest moisture content of fresh fish was 78.2% in Shatt Al - Arab samples while the lowest 70.8% was in fresh cage fish. The highest moisture content in iced fish 79.4% was in imported samples while the lowest 74.1% was in cage fish. As for ash content, the statistical analysis revealed significant differences (p<0.05) between imported fish and other fish samples. Significant differences (p<0.05) were observed also between fresh pond fish and other samples.However, no more significant differences (p>0.05) were detected between other fish samples. The highest ash content in fresh fish 2.29% was in pond fish and the lowest 0.98% in imported fish. Similarly, the highest ash content in iced samples 1.45% was in pond fish and the lowest 0.87% in imported samples. The statistical analysis of fat contents demonstrated significant differences (p<0.05) between Shatt Al - Arab fresh and iced samples and other samples. Fat content in pond fish was in line with those in iced cage and iced imported fish but significantly (p<0.05) differ from those in fresh pond and imported fish while no such differences were shown between pond and imported fish. The highest fat content in fresh fish 11.9% was in imported fish and the lowest 3.43% in Shatt Al - Arab fish. Similarly, the highest fat content of iced fish 9.99% was in imported fish and the lowest 3.17% in Shatt Al - Arab fish. The statistical analysis showed that protein contents in fresh fish from Shatt Al - Arab, ponds and cages were significantly (p<0.05) higher than those in imported fish while protein contents in fresh and iced imported fish were significantly (p<0.05) lower than it in other fish. The highest protein content in fresh fish 18.71% was in pond fish and the lowest 10.05% in imported fish. Similarly, the highest protein content in iced fish 16.96% was in pond fish and the lowest 9.98% in imported fish. The statistical analysis showed that the caloric values of fresh and iced fish from Shatt Al - Arab were significantly (p<0.05) lower than other fish except for iced pond and imported fish. Additionally, no significant differences (p>0.05) were observed in caloric values between pond, iced cage and imported fish while pond and Shatt Al - Arab fishes only showed significant differences (p<0.05) in comparison with other samples. The highest caloric value for fresh fish 165.62 Kcal/100 g in cage fish and the lowest 98.5 Kcal/100 g in Shatt Al - Arab fish. On the other hand, the highest caloric value for iced fish 148.4 Kcal/100 g was in cage fish and the lowest 93.9 Kcal/100 g in Shatt Al - Arab fish.The fatty acids was assessed in the laboratories of The College of Agriculture, University of Basrah by using GC - MS QP210 Ultra , SHIMADZU, JAPAN equipped with capillary column DB - MS 5 with static phase (5% phenyl, 95% methyl polysiloxane) and ultra - high purity Helium 99.9%. The fatty acid analysis for the muscular tissue of fish indicated high levels of oleic ،palmitic ،stearic ،stearic ،docosahexaenoic acid in comparison with lower levels of myristoleic ،eicosadienoic ،dihomo - gamma - linolenic and pentadecyclic acids. The statistical analysis revealed no significant differences between both fresh and iced samples from the different fish sources. However, significant differences (p<0.05) were detected between imported fish and fresh and iced fish from ponds and cages. Additionally, no significant differences (p>0.05) were observed between fresh and iced imported samples with both fresh and iced pond fish while fresh and iced cage fish differed significantly (p<0.05) from fresh pond samples.Amino acids were assessed by using HPLC system with ion exchange and Ninhydrin post column derivation in Shimadzu Spd - 6 Av uv - Visible detector. The analysis of amino acids in fish muscular tissue demonstrated high levels of Aspartic ،Serine ،Glutamic،Alanine and Glycine and low levels of Cystine ،Tryptophan ،Isoleucine ،Methionine،Histidine ،Threonine and Tyrosine. The statistical analysis showed no significant differences between fresh and iced Shatt Al - Arab samples with fresh and iced imported fish. No significant differences (p>0.05) were observed also between fresh and iced pond fish with fresh and iced cage fish. On the other hand, significant differences (p<0.05) were found between fresh and iced Shatt Al - Arab fish with fresh and iced imported samples. Additionally, another significant differences were detected between fresh and iced pond fish with fresh and cage fish.As for the total bacterial count, the statistical analysis revealed significant differences (p<0.05) between all fresh and iced fish samples. The highest level in fresh fish 7.6 x 103 cfu/g was observed in Shatt Al - Arab fish while the lowest level 2.0 x 103 cfu/g in imported fish. In comparison, the highest level in iced fish 7.44 x 107 cfu/g was also in Shatt Al - Arab fish but the lowest level 5.72 x 107 cfu/g in cage fish.

Abstract: The aimed of the present study to find out the nature of the qualitative compositionand some biological aspects in the North part of Shatt Al - Arab River and some of its reaches after emergence of many changes in the region and habitats segmenting by Dam construction on Euphrates River in the area between Chibyish and Mudina town and establishment of Qlat - Salih Regulator, reduction of water discharge to minimum limits, entry of alien species on an ongoing basis, so it is necessary to conduct a study to find out the nature of the diversity of fish in the region, and it has shown that the composition of community differs from previous studies revealed that introduced alien small size species and some of uneconomic species were dominate. The samples were caught monthly from the river from December 2013 to May 2015 North of Basrah Province. Several fishing tools were used to collect fishes seine, fixed, draft, cast net and electrofishing. Three stations were selected; the station 1 was in the North of Qurna town about five kilometers North the point which the Tigris and Euphrates River confluence, station 2 at the place of Seweeb River is meeting the Shatt Al - Arab Rive and station 3 at the point that Al - Shafii River which meet Shatt Al - Arab river. Some environmental parameters were measured, namely air temperature ranged from 15ºC in December 2014 in station 3 to 43ºC in the August 2014 at station 2 and 3, while the water temperature from 11ºC in January 2015 for station 1 to 36 ºC in July at station 2. Light penetration revealed 33 cm in April and May 2014 and 132 cm in January 2015 for station 3. Current speed ranged between 0.03 m/s in January 2015 in station 3 and 0.29 m/s in October 2014 for station 1. Salinity ranged from 0.66 g/L in January 2014 for station 1 to 1.46 g/L in February and March 2015 in station 1 and October 2014 for station 2. The pH values tend toward the alkaline, the lowest 7.30 in May 2014 for station 2 and 8.90 measured in February 2014 in station 1. Monthly discharges, average incoming from the Tigris River recorded 35.20 ± 8.47 m3/s in November 2014 to 73.85 ± 17.55 m3/s on February 2014. Lower values of reactive nitrate were recorded 0.69 μ g at. N/L in March 2015 at station 3 and highest 24.32 μ g at. N/L in May for station 2, however the values of reactive phosphate recorded, the lowest 0.0037 μ g at. N/L in March 2015 at station 2, the highest was 0.589 μ g at. N/L in November 2014 for station 1. A total of 29405 individuals was collected during the study period represented 916521g included 33 species eight of them were marine species contain 29 genera belong to 14 families of Osteichthyes, Cyprinids family occupied first degree in the number of species (13) and genera (12), the numerical relative abundance of marine species in the study area was 3.38% and the relative abundance gravimetric was 8.45%. A significant positive correlation was found between number of species and water temperature (r=0. 506). Liza abu, Carassius auratus and Coptodon zillii were the most total numerical relative abundance 30.89, 29.30 and 15.64 % respectively, C. auratus, S. triostegus and C. zillii were the most total weight relative abundance and composing 27.58, 14.27 and 11.64% respectively in the study area. Discharges rates flowing from the Tigris River revealed negative effect with the number of species and the insignificant negative correlation was recorded (r= - 0.109) with discharge monthly rates, and fluctuation relationship was noticed between discharges and ecological indices. However, native species included 15 seasonal species 4 and 14 for rare species. Diversity index (H) ranged between 0.91 in January 2015 at station 3 to 2.05 in March 2015 for station 2, richness index (D) 0.83 in February 2014 at station 3 and 2.79 in March 2015 at station 1, evenness index (J) recorded 0.38 in January 2015 and the highest 0.78 in September 2014 for station 1. The percentage of similarity among stations by Jaccard similarity index (Ss%) showed variation uneven during study months. Cluster analysis of species similarity pointed to clumping in groups controlled by temperature. The Multivariate analysis was (CCA) adopted to clarify the impact of a biotic factors on the distribution of species. Total catches were ranged between 16380 g in December 2013 to 80309g in December 2014. The total average catch per unit of effort was 24.953 kg/hr for seine nets ranged from 0.928 kg/hr in December 2014 at station 2 to 30.271 Kg/hr during January 2015 for station 3. The number of fishing boats in the study area 143 their length between 5 - 7m most of them without an engine. The impact of alien species direct effects during the destruction of nests and reproductive ground, especially eggs which lie on a plant for native species and hybridization between alien and native species, and indirect effects of competition on food, ecological space, environment destruction and aggressive behavior. The length groups of all fish species were recorded, the lowest values were for Alburnus mossulensis, Acanthobrama marmid, Hemiculter leucisculus and Garra rufa, they were 7.3 - 18, 6.3 - 17, 7 - 17 and 7.2 - 17.8 cm respectively, whereas the highest were for Silurus triostegus, Leuciscus vorax and Mastacembelus mastacembelus, they were 10.8 - 72.4, 9.5 - 57.3 and 14 - 55 cm respectively. Faben method used for estimating growth parameters (L∞,K) by applying FiSAT program for C. auratus, Carasobarbus luteus and L. abu, the values of L∞ for three species 38.97, 35.69 and 22.19 cm respectively, and for K 0.29 to the C. auratus and C. luteus and 0.41 for L. abu, the results revealed five years age for C. auratus and C. luteus whereas four years age for L. abu. The present study showed high values of diet overlap between L. abu and Cheon subviridis 09% also high values 90% Oreochromis aureus and Oreochromis niloticus S. triostegus and L. vorax 89%, but it did not reach the competition limit, also high diet overlap 86% and competition was found between C. auratus and C. luteus Absolute fecundity for C. auratus females ranged from 1303 for 8.8 cm total length and 10g weight to51245 egg for 30.1 cm total length and 557g weight, and for C. luteus from 2098 for 13.1 cm total length to 14147 egg for 20.9 cm total length and 131g weight, while in L. abu from 6247 for 9.7 cm total length and 11g weight to 41219 egg for 17.5 cm total length and 63g weight.

Abstract: An Ecological study was conducted, on monthly basis, for the period from November 2013 to October 2014, on the Lower reaches of the Euphrates River covering a location at northwest of Basrah province within the area between Al - Chebaysh district of Thi Qar province, and Mudayna district of the city of Basrah. The study area covered a distance of 16 kms lies between latitudes 47˚00 ' 18.81 " and 47˚09 '55.46" E and latitudes 30˚57' 41.53" and 30˚57'7.38" N. On 2010 the Ministry of Water Resources constructed an obstruction on the Euphrates River, 11 km west of Mudayna of a width 760 m. It’s aims is to raise water levels in the western side of the river for water to flow to Hor Al - Chebaych. Three stations were selected to execute the study. The former was situated in front of the Chebaish district and with a distance of nine kilometers east where station 2 was located. However, to the east of the constructed embankment and just three kms apart station 3 was chosen. The study revealed that air temperature ranged from 11 - 45°C and water from 10.5 - 37°C, light penetration from 15 to 210 cm. Turbidity from 0.66 NTU in October at station3 and 40.8 NTU in September at station1. Current speed ranged between 0.01 m/s to 0.41 m/s.The lowest value of Electric conductivity (2.4μS/cm) recorded in November at station 3 and the highest (5.74μS/cm) in March at station 1. Total dissolved solids between 1788 mg/ L to 3832 mg/L. the lowest value of pH (7.4) measured in August at station 2 and the highest (8.7) in February at Station 3. Dissolved oxygen ranged from 5.5 to 10.1 mg/L. BOD5 ranged from 0.19 to 3 mg/L. The lowest value of salinity (1.3 g/L) recorded in June and July from Station 2 and the highest (2.9 g/L) was encountered in February at station 3. Total hardness the lowest (880 mg/L) encountered in July at station2 and the highest (1350 mg/L) in February at station3. Total alkalinity ranged from 84 to 182 mg/L. Reactive nitrate ranged from 0.6 to 37.7μg at. N/L. Reactive phosphate ranged from 0.023 to 1.857μg at. P/L. Concentrations of some heavy metals were also studied. Copper was impalpable in November and December in stations2 and 3, but the highest (1.90 μg/L) was in August at station2. Intangible value was also recorded for Lead in November at station3 and the highest (0.1 μg/L) in July of the same station. Non - tangible value encountered for cadmium in November and December at stations 2 and 3 but the highest (12.73 μg/L) in July for station1. The study took in consideration application of the general index to the quality of water (CCME) as seasonal readings were calculated depending on river maintenance system for the year 1967 and amended in 1980. Throughout the study period values ranged between marginal (56.3) and FairB(69). Values were obtained depending on the previous studies, as were between marginal (47) and Fair( 65). Fish community structure was described. A total of 11851 specimens were collected included 28 species and 25 genera belonging to 12 families all belong to class bony fishes Osteichthyes. Cyprinidae came first concerning the number of species (13) and genera (11) and composing 37.44 %, these are Hamri (Barbus luteus), Prussian carp (Carassius auratus), grass carp (Ctenopharyngodon idella), (Acanthobrama marmid), (Alburnus mossulensis), Shillug (Aspius vorax), bunni (Barbus sharpeyi), gattan (Barbus xanthopterus), Hemicultuer leucisculus), small mouth benine (Cyprinon kais), big mouth benine (Cyprinon macrostomum), (Garra rufa) the mullet family Mugilidae formed 35.50 % and consist two species , namely, Liza abu green and Liza subviridis. Tilapia Cichlid family was represented by 21.84 % and two species, namely Tilapia zilli and Oreochromis aureus. Gumbusia (Pociliidae) formed 2.70% and represented by two species , namely (Gambusia holbrooki) and Poecillia latipinna, Clupeids family accounted for 0.025% and represented by two species, namely Tenualosa ilsha) and Nematalsoa nasus. However one species of seven families included Siluridae (Silurus triostegus) 0.58%, Sparidae Acanthopagrus latus (arabicus) 0.57%, Mastacembelidae (Mastacembelus mastacembelus) 0.28% , Hemiramphidae Hyporhampus limbatus)) 0.23% and minnows Engraulidae (Thryssa whiteheadi) rate of 0.345 % and Gobiidae (Bathygobius fuscus) was collected for the first time in the study area and in station 3 at 0.050 % and Heteropneustidae (Heteropneustes foosilis) formed the lowest contribution. The study also was taken in consideration the diversity indices in the Euphrates. The lowest value (1.04) of Shannon diversity index (H) was recorded in May from station1 and the highest (2.70) in the same month from station3, and was the lowest value for the evenness index (J) (0.476) in May was recorded for the station1 and the highest (0.933) in January. The lowest value of richness index (D) (0.868) was obtained in December from station1 and the highest (3.285) in May from station3. The lowest value for Jaccared similarity index (13.25 %) was in October between stations1 and 2 and the highest (100 %) in November and January between stations 1 and 2. Multivariate analysis (CCA) was applied to clarify the relationship between abiotic environmental characteristics and fish distribution in the aquatic environment.

Abstract: Three Stations were selected based on its pollution level, first station was (Ashar chanel N : 30 º 31 13.31, E : 47º 50 13.63) the second station was (Shatt Al Arab N : 30 º 30 0. 29, E : 47º 51 36.31) and the third station was (Qurna N : 31 º 0 12. 79, E : 47º 26 37.11). Samples of waters, fish and sediments were collected monthly, collection of these samples started from Nov. 2013 till Oct. 2014 during the ebb time, group of physical and chemical variables had been measured like air and water, temperature, salinity, electrical conductivity, light penetration, pH, dissolved oxygen, biological oxygen demand, Total alkalinity (TA), Total hardness (TH), reactive nitrite, nitrate and phosphate, chlorophyll a in water, total organic carbon (TOC) in sediments, Soil texture was identified for each station through knowing the ratios of its components. Also, through the current study banthic algae were identified in areas of intertidal area, the parasitic copepod on fish also identified as biological indicator for the pollution at the selected stations.The study revealed that the air temperature varied between (17.5 - 43.2)Co while water temperature varied between (12 - 31) Co, the salinity varied between (0.57 - 4.16) ‰, while the electrical conductivity ranged between (0.9 - 6.5) mellisemince/ cm, while light penetration values were varied between (17 - 90) cm, pH values varied between (7.2 - 8.5), dissolved oxygen values were ranged between (3.5 - 11.2) mg/ l, while the biological oxygen demand varied between (1.2 - 9) mg/ l, value of TA and TH were varied between (81 - 190) mg/ l and (822 - 2123) mg/ l, respectively. The current study also recorded the concentrations of nutrients, that the values of nitrates and reactive nitrites ranged between (0.1 - 2.71) μg N - NO2/ l, (12.11 - 42.1) μg N - NO3/ l, respectively, while the reactive phosphate valuesbwere ranged between (1.31 - 9.98) μg P - PO4/ l, on the other hand the value of chlorophyll a were from (8.12 - 20.13) mg/ l.It was recorded in the current study a recognizable raise in values of total organic carbon (TOC) in the first station due to its highly exposed to the organic pollutants in comparison with the second and the third station, the values of (TOC) varied between (15.33 - 45.63)%, (4.4 - 22)%, (9.02 - 44.6)% for the three stations respectively.The current study demonstrated that the prevalence of green algae, all over study time in the second and the third station like (Cladophora fract, C. glomerata, Enteromorpha intestinalis, Schizomeris liblenii) also it was nocied that the Rhizoclonium crassipellitum was available more in the second station than the first and the third station, due to that the second station was featured with less contamination with organic materials. Some of the blue - green algae like (Lyngbya Birgei, L. major, Oscillatoria, amoena O. tenuis) showed prevealance in the first station because of the abundance of the organic pollutants, the red algae Compsopogon coeruleus, was recorded at three stations, the highest percentage was in the third station, the lowest percentage was recorded in the first station. It was also found in current study based on using algae as biological indicator for pollution, which prepared by Palmer. The first station was highly polluted with organic matter in comparison with other two stations, due to abundant of species which used as organic indicator of pollution. Results reavaled monthly variations in total number of benthic filamentous algea, which increased during two periods (Bimodel). Values of diversity ranged from 0.626 in station two to 2.15 in station two.The monthly variations in Organic Pollution Index (OPI) were different between three stations and ranged (25.54 - 48.72), (4.52 - 38.9), (15.14 - c28.69), in three stations respectively. The highest value 48.72 (Poor) was recorded in Ashar chanal at August and the lowest value 4.52 (Good) in Shatt Al - Arab river at December.Aquatic systems are affected by a variety of anthropogenic activities that decrease water quality through the introduction of organic pollutants. To investigate the relationship between fish parasite communities and water quality, copepods parasites were examined in 856 specimens of the fishes (Acanthobrama marmid, Acanthopagrus arabicus, Alburnus mossulensis, Carasobarbus luteus, Carassius auratus, Chelon subviridis, Coptodon zillii, Cyprinus carpio, Garra variabilis, Gambusia halbrooki, Leuciscus vorax, Liza abu, Luciobarbus subquincunciatus, Luciobarbus xanthopteru, Nematalosa nasus, Oreochromis aureus, Poecilia latipinna, Silurus triostegus, Tenualosa ilisha), sampled in three sites in the Basrah Province, Quran site (unpolluted), the Shatt Al - Arab (moderately polluted) and Al - Asher canal site (polluted). Six species of copepods, Ergasilus rostralis, E. mosulensis, E. ogawai, Ergasilus sp, Lernaea cyprinacea and Mugilicola kabatai were found in unpolluted site, and four species of copepods, E. rostralis, E. mosulensis and Lernaea cyprinacea were found in moderately polluted site, but the distribution of copepods was limited to the polluted site (Ergasilus rostralis, E. mosulensis and Lernaea cyprinacea). The variability of the calculated infection indices (prevalence and mean intensity) are affected by the pollution levels of the water. The unpolluted site had the highest species and the highest overall parasite abundance values.

Abstract: Tilapia (Oreochromis aureus) was used to investigate the effect of salinity on Osmoregulation and growth. One hundred ninety fish were collected from Al - Sweeb River / Qurna. Acclimation on laboratory conditions was done for 24 days. The abrupt salinity transfer experiment was done using the following salinities : 1.5, 5,10,15,20,25 and 30 g/l during 96 h. Survival rate was calculated and reached to 90% in salinity 20 g/l , while it decrease to 0% in salinity 25 g/l. LC50 was calculated and was 20.44 g/l. Gradual salinity increase was conducted and was shown that survival rate increased to 80% in salinity 30 g/l, while it was 0% in salinity 35 g/l. Growth experiment was conducted for 120 days using the following salinities : 1.5, 5,12g/l. the results showed that food intake decrease to 18%, 37%, 43% with increasing salinity to 5, 12 and 20 g/l (respectively) comparing with the control. The role of gut and muscles in water and ionic regulation, chloride cell aggregation in gills and operculum, oxygen consumption rate, energy usage was also studied during salinity acclimation.The results showed that water content decreased in the muscles to 80.1%, 79.58% during salinity increasing to 5 and 12g/l (respectively) comparing with the control. While the water content in the gut increased to 90.4% and 91.44% with increasing salinity to 5 and 12 g/l (respectively) comparing with the control (83.05%). Ionic content also affected with increasing salinity to 5 and 12 g/l , as Na+ concentration in the muscles increased to 30.33, 38.18 m Mol /kg tissue water (respectively) comparing with the control (19.14 m Mol/kg tissue water). While in the gut, Na+ increased to 34.02 and 42.26 m Mol/kg tissue water (respectively) comparing with the control (18.04 m Mol/kg tissue water). K+ concentration in the muscles also increased to 59.23 and 60.23 m Mol/kg tissue water when salinity increased to 5 and 12 g/l (respectively) comparing with the control (49.3 m Mol/kg tissue water). While in the gut ,K+ concentration increased to 68.61 m Mol/kg tissue water with increasing salinity to 5 g/l and decreased to 57.30 m Mol/kg tissue water in salinity 12 g/l ,comparing with the control.bWith increasing salinity, the percentage of chloride cells in the gill epithelia increased to 7.5% and 9.39% with increasing salinity to 5 and 12 g/l (respectively) comparing with the control (5.7%). In the Opercular epithelia the percentage of chloride cells also increased to 3.33% and 4.04% with increasing salinity to 5 and 12g/l (respectively) comparing with the control (3.07%).After 24 hours of salinity increasing to 5, 12 and 20 g/l, the rate and percentage of oxygen consumption increase to 267.71 mg/kg/h (17%), 306.38 mg/kg/h (34%) and 404.21 mg/kg/h (77%) (Respectively), comparing with the control (228.57 mg/kg/l). The increase in oxygen consumption rate was coincide with increasing in the rate and percentage of energy usage to 0.90 Kcal/kg/h (16%), 1.03 kcal/kg/h (33%) and 1.36 Kcal/kg/h (77%) with increasing salinity to 5, 12 and 20 g/l (respectively) comparing with the control (0.77 Kcal/kg/h).Food intake after four days of increasing salinity decreased to 2.27, 1.73 and 1.58 g/100 g fish when salinity increase to 5, 12 and 20 g/l, comparing with the control (2.76 g/ 100 g fish ).The results of the growth experiment after 120 days of transfer to higher salinities (5 and 12 g/l) showed that the growth rate was affected largely with salinity and temperature, as the weight of fish declined during the first 10 weeks when water temperature was ranged between 24 - 30o c , while significant increase in fish weight was recorded with increasing water temperature to above 30o c.The results of chemical compositions of the whole body at the end of the growth experiment showed a decrease in the fat and protein content with increasing salinity. This may be explained as the fish depend on body storage of protein and fat as

The youngest member of himri ( 65 mm, 5 g) encountered in April, while the largest ( 280 mm, 257 g) collected in July . monthly changes in feeding activity and feeding intensity of the studied species were calculated, the highest recorded during the spring and summer months and the lowest in the winter. The highest activity, however, was in May for jerry and shillig, whereas for himri was in April, May and June . The highest degree of food intensity for jerry was in June and in October for shillig and himri.The highest percentages of empty stomachs was recorded in the winter months and the lowest in summer and spring. It was found that there is a correlation between water temperatures (jerry : r=0.301, shilling : r=0.111, himri : r=0.397) and fullness index and feeding activity of the three species. Results showed the continuation of the species in feeding throughout the year in spite of the decline in the food quantity with low temperatures. Stomachs contents were investigated by using the three methods of analyses. volumetric, numerical and the frequency of occurrence in order to overcome the disadvantages of each method. Index of relative importance was adopted to calculate the relative importance of each food item of the three species. Fish were of the highest importance food item in the diet of jerry which ranged between (97 - 100%) and followed by crustaceans and aquatic plants. Fishes also came first in shilling diet ranged between 74.9 - 99.6% followed by crustaceans and insects, while mollusca was insignificant in the diet.Aquatic plants were of the most importance in himri diet (49.3 - 99%) followed by crustaceans and aquatic insects (18 - 20 %) mollusca (0 - 16.3%) fish (0 - 10.1%) and algae (0 - 5.7%) . Results showed that jerry was a predator feeding mainly on fish and crustaceans. whereas shillig was carnivore but it's diet was more diverse as its alimentary canal contained fish, crustaceans, aquatic insects mollusca. The study also concluded that himri was omnivore as relied on six food components where aquatic plants came first, followed by the rest of the categories, namely algae, aquatic insects, crustaceans, fish and molluscs, but they tend mainly to consume vegetation more than diet of animal source.The study also examined the difference in food habits nature of various sizes of the studied species.Two sizes were elected for jerry i.e. of more than 450 mm and less than 450 mm. Two sizes of shillig and himri were also chosen, namely more than 200 mm and below 200 mm . Results showed a slight discrepancy infood items among the different sizes of the investigated species of fish. The study showed diet overlap between the two carnivore species ( jerry and shillig ) , amounting to ( 0.88 ) . Diet overlap was low and symmetric between jerry and himri (0.2 ) on one hand and shillig and himri (0.2 )on the other

Abstract: Investigation of the reproductive strategies of Arabian carpetshark Chiloscyllium arabicum (Gubanov, 1980) and Arabian whipray Himantura randalli (Last, Manjaji - Matsumoto et Moor, 2012) were conducted in Iraqi marine water from January, 2014 to December, 2014. A total of 365 Arabian carpetshark (200 female and 165 male) with total length ranged from 141 - 750 mm and 321 Arabian whipray (176 female and 145 male) with disk width ranged from 70 - 429 mm were cached. Trawling nets of Bahith Ship (owned by Marine Science Center) or other fishing boats were used to cached these fishes.Sex ratios of these fishes were investigated during study period. The cycle of gonad maturation was followed - up throughout the period of investigation by defining stages based on colour, shape and size of gonads. Fecundity was estimated and spawning period detected depending on gonado somatic index (GSI), hepato somatic index (HIS), histological study and sonar inspection.The length frequency distribution of Arabian carpetshark was dominated by group of 300 - 399 mm that appeared in all months except October. Smallest fish (142 mm, 20 g) was during October and biggest fish (750 mm, 1668.5 g) during June. The length - weight relationship was represented by the following equations : Male W= 0.000007 ×L 2.88Female W= 0.000005 × L 2.93 Both Sex W= 0.000006 × L 2.91Values of HSI was differ depending on the maturing conditions of males and females, where highest value (11.906) of HSI for females was recorded at October and lowest value (6.908) was recorded at June, while highest value (12.5) of HSI for males recorded at January and lowest value (9.14) recorded at March. There were negative correlation between oil ratioof liver and maturing condition of females, while in males this relation was not clear.Distinguishing of sex was carried out according to presence or absence of claspers. Smallest matured female was 421 ml in total length and 785.23 g in weight, while smallest matured male was 401 in total length and 693.14 in weight. Females were dominant on males during all months except February, August and November with equal sex ratio during March, while overall sex ratio was 1 : 1.26 toward females.The cycle of gonad maturation was divided into three stages : immature, maturing and mature for males and females. Linear relationship was found between total length (TL) and clasper length (x) and it was represented by following equation : TL=211.3479 + 0.013883 x X, with significant (P<0.05) correlation (r= 0.899) between them.The GSI values were different during study period, where highest values (8.84 and 7.93) for females recorded during April and May respectively and lowest value (0.73) during June, while highest value (6.74) for males recorded during March and lowest value (0.66) during May. Monthly differences in GSI especially for females refers that spawning period extended from May to June. This result supported by the results of frequency occurrence of germ cells. Results appeared that ovary of Arabian carpetshark contain 44 - 52 eggs with diameters between 22 - 48 mm. Depending on histological inspection of gonads, spermatocytes cells for males are divided into eight maturing stages, while spermatocytes cells for females into four maturing stages.Disk width (DW) frequency showed fife groups for Arabian whipray with dominant of 300 - 399 mm group that appeared in all months except October, while group of 200 - 299 mm was appeared in all months. Group of0 - 99 mm appeared in July and August, so it was concluded that reproduction occurred in July. Smallest fish (70 mm, 20 g) was cached during July and biggest fish (490 mm, 3834 g) was cached during June. Relationships between disk width and weight were as follow : Male W= 0.00031 x DW2.59 Female W= 0.0031 x DW2.31 Both Sex W= 0.0006 x W2.4HSI differed according to maturing conditions of males and females, where highest value (11.85) for females recorded during January and lowest value (6.04) recorded during June, while highest value (11.66) for males recorded during November and lowest value (7.48) recorded at March. There were negative correlations between gonad weight and liver weight of females and also between oil ratio of liver and maturing condition of females.Smallest matured female was 115 ml in disk width and 1936 g in weight, while smallest matured male was 355 in disk width and 1249 g in weight. Sex ratio was differ from the ratio of 1 : 1 during different months and at reproduction period the ratio of females was 64.5% and of males 35.5%, while the ratio was 50% for each sex after reproduction period at August. Females were dominant on males during all months except September and December and overall sex ratio was 1 : 1.26 toward females.Maturing cycle were divided into three stages : immature, maturing and mature for males and females. For males the dividing depending on morphological characteristics (length, size and colour) of claspers. Linear relationship was found between disk width and clasper length (x) and it was represented by following equation : DW=92.4133 +0.2233 x X .GSI showed differences throughout study period for both sexes. The highest value (8.63) for females recorded during June and lowest value (0.81) during July, while highest value (7.59) for males recorded duringJanuary and lowest value (0.97) during March. It was concluded, according to GSI especially for females, that birthing occurred between June and July.Number of eggs in the Arabian whipray ovary was ranged between 10 - 35 eggs and diameters between 5 - 28 mm, while the uterus contain 2 - 5 embryos that surrounded by strong covers and there wasn’t any placenta intelligence between embryos and female, so this fish considered as Ovoviviparous. Depending on histological inspections of gonads, spermatocytes were divided into seven maturing stages, while oocytes into four maturing stages.

Abstract: The present study describes the composition of fish assemblage of the Garmat Ali River by adopting the ecological indices, and focusing on the changes in the structure of fish assemblage and the environmental factors. The ecological status of the river was evaluated by applying water quality index (CCME - WQI) and fish integrated biological index (F - IBI).Water and fish samples were collected on monthly basis, from the three stations during the period from November 2015 to October 2016.The study showed that air temperature ranged from 17.3ºC in December to 35.7 ºC in September, water temperature varied from 14.3 ºC in December to 32.7 ºC in September, transparency fluctuated from 17.7cm in July to 55.0cm in January, salinity ranged between1.5‰ in June to 6.0‰ in December and the pH varied from 7.2 in August to 8.3 in November. Water quality index of the river was classified as marginal (WQI= 49.5%). A total 34 fish species belonging to 26 genus and 16 families were caught using seine net, fixed gill net and electro - fishing, all species belong to Osteichthyes. Cyprinidae is a dominant family represented by seven species.The number of species caught was 9 in January and 25 in May. The fish fauna consisted of 18 marine, eight native and eight exotic species. The resident species consisted of 14 species, three species seasonal and 17 species occasional. Poecilia latipinna was the most abundant species numerically and in weight comprising 57.66% and 35.45%, respectively, followed by Tenualosa ilisha (15.29%, 22.38%). The third position in number was occupied with Thryssa whiteheadi (7.96%), but Carassius auratus in weight (10.16%). The dominance value (D3) for the more three abundant species in number (P. latipinna, T. ilisha and T. whiteheadi) was 80.91%, while in weight was 67.99% for P. latipinna, T. ilisha and C. auratus.The overall numerical diversity index ranged from 0.47 in February to 1.66 in October, but the weight diversity index ranged between 0.79 in February and 2.05 in April. The overall numerical evenness index varied from 0.23 in February and 0.63 in October, andthe weight evenness ranged between 0.37 in February and 0.73 in November. The overall richness index ranged from 1.05 in February to 2.26 in April.Associations between the numbers of species and individuals of fish and the environmental variables were clarified by using canonical correspondence analysis (CCA). The analysis was indicated that T.whiteheadi, T. vetrirostris, Coptodon zilli , Oreochromis aureus C. auratus and T. ilisha have been associated with water temperature, and P. latipinna has been associated with salinity.Cluster analysis reveals five main groups according to the Jaccared similarity index and three major groups according to Schooner' s similarity index. The integrated biological index (IBI) scores were calculated from 15 separate assemblage metrics based on the fish species richness, species composition and trophic guilds. The ecological status of the river was found to be impaired (F - IBI=46.5%).The study shows that the deterioration of the water quality of the Garmat Ali River during the last years, which reflects the deterioration of the water quality of both Shatt Al - Arab and East Hammar marsh, has affected on the composition of fish assemblage of the river fish in terms of the decrease in the number of native or endemic species and the increase in the numbers of marine and exotic species. This is confirmed by the value of F - IBI, which reflect the state of the ecological disturbance of the river.

Abstract: Addrressed study in alimentary gut morphology and relationship feeding of three fish species with different food habits i.e. Leuciscus vorax (Shilik) as a carnivore, Planiliza abu (Khishni) as an omnivore and Oreochromis aureus (tilapia) as a herbivore and the activity of alpha - amylase enzyme. Each species was divided into two length groups : 1 - Shilik 300≥ (227 fish) and ˂300 mm (117 fish) .2 - Khishni 100≥ (508 fish) and ˂ 100 mm (706 fish) .3 - Tilapia 150≥ (270 fish) and 150 mm ˂ (309 fish) .Fish were sampled monthly during the period from February 2014 to January 2015 using cast net and an electrical apparatus. Air temperature in the study area during that period ranged between 14 and 33°C and water temperature between 12 and 32 °C, while salinity ranged between 1.42 and 2.9 ppt.Appearance of Shilik mouth was characterized by a superior position, toothless jaws and barbells. The mouth position in Khishni and Tilapia was terminal with an extension of buccal cavity. Khishni lacked mandibular teeth which related to its feeding habits, while 3 - 4 rows of teeth were existed in the lower jaw of tilapia to cut plants parts.The three fish species has four branchial arches which were different in length reflecting the respiratory and feeding needs. the average length of the first arch of Shilik for the two length groups were 34.93 and 73.42 mm, in Khishni 13.96 and 19.41 mm and in tilapia between 22.63 and 37.86 mm, respectively. Gill rakers of the three species differ in length and number to accommodate their feeding habits. The average length of gill rakers in Shilik was 1.78 and 3.78 mm, in Khishni it reached 1.09 and 4.12 mm and in tilapia were between 1.91 and 2.06 mm. The number of gill rakers differed between species and ranged in Shilik between 10 - 12 to 12 - 14, in Khishni between 45 - 55 to 62 - .55 while in tilapia 21 - 22 to 22 - 24. The pharyngeal teeth in Shilik substituted the absence of mandibular teeth and its equation was ( 5.3 - 3.5). Khishni oral cavity contain a pair of pharyngeal teeth with a rough surface helps in grinding sand and mud solid particles with a length ranged from 5.14 to 8.02 mm and a width from 3.34 to 4.78 mm. Tilapia length of pharyngeal teeth were 4.91 and 9.61 mm, and the width was 4.37 and 7.28 mm.It was possible to distinguish two gut areas in the three species depending on diameter, where the anterior was wider than posterior area. The anteriorbintestine thickness were 23.74 , 4.29 and 3.34 mm, while the posterior thickness were 7.28 , 2.42 and 1.62, respectively. These differences confirm the variations in feeding habits. The relative gut length (RGL) of Shilik was 1.11 and 1.08 mm for the two length groups with no significant correlation with the standard length. In Khishni, it was 2.79 and 3.45 mm with 7 - 9 loops and the statistical analysis did not show significant correlation with standard length.The gizzard of Khishni through which food coarse are crushed, reached a width, height and wall thickness of its wall of 8, 4.26, 2.84 and 12.24, 6.24 and 4.59 mm, respectively. Tilapia RGL were 9.50 and 10.25, respectively.The stomach contents of the studied species were examined by dissected and compound microscope, using weight percentages, points and frequency of occurrence methods to calculate the index of relative importance (IRI). The three species showed similar patterns in the feeding intensity and activity during the study period with lowest values recorded during summer and the highest during spring.Result levins index showed That individual of the Shulik were small narrow specialization (0.27) and large (0.25) highly specialized, with fishes Khushnia (0.42 and 0.37) and blu tilapia (0.32 and 0.32) and were narrow specialization of small and large individual, respectively.The results of proximate analysis showed differences in the natural food of the three species depending on the feeding habits of these fish. The moisture content and energy where(%69.47 and 26.82 kcal / gm) ,(% 52.23 and 5.08 kcal/ gm) ,(%61.25 and 5.40 kcal / g) for smaller length , while it was (%68.93 and 11.50 kcal / gm) , (%55.14 and 5.01 kcal/ gm ),( %64.75% and 6.08% kcal/ gm) for larger lengths. The percentages of ash and organic matter rated (%51.57 , 48.43 and %31.96 , 68.0 and %47.53 , 52.46) for smaller lengths and (%23.56, 76.44 and %36.75, 63.24 and %44.57, 55.41) for large lengths. Organic carbon rate was higher (1,72 and 2.94 and 1.61) during summer, winter and autumn for first length group of Shilik, Khishni and tilapia, respectively, while second length group reached higher rate (1.61 and 2.67 and 1.72) during spring and autumn in Shilik, spring, summer and autumn in Khishni, and only autumn in blu tilapia.Alpha - amylase showed an elevated enzymatic activity in herbivorous and omnivorous in comparison with carnivorous fish confirming its main function in the hydrolysis of starch molecules .

The concentrations of lead as dissolved part in water rangedBbetween( ( 0.86 μg/l in Jul. and ( 3.1 ) μg/l in Apr. , and in the exchangeable part of the sediment between ( 0.78 ) μg/g in Aug. and ( 2.41 ) μg/g in Apr. , while the content in T. domingenesis ranged between ( 0.38 ) μg/g dry weight in Jan. and ( 0.71 ) μg/g dry weight in Aug. ,Whereas cadmium as dissolved part in water ranged between ( 1.0 ) μg/l in Nov. and ( 2.8 ) μg/l in Apr. ,while in the exchangeable part of the sediment ranged between (0.6) μg/g in Apr. and (2.0) μg/g in Mar. ,and ranged in the T. domingenesis between (0. 3) μg/g dry weight in Jan. and(0.6) μg/g dry weight in Aug. ,The value of organic carbon in sediments ranged between (0.162)% in Nov. and(0.458)% in Jul. .Carlson Trophic State (CTSI) Index were used, based on three variables, namely chlorophyll - a - , total phosphorus and transparency to assess the nutritional status according to the primary productivity, Al - Mndhuri and Al - Daoudi stations were evaluated to be mesotrophic category values ranged between (41.42 - 46.68) for Al - Mndhuri station and between (45.63 - 40.44) for Al - Daoudi station during the months of August and October respectively. while Al - Zerki station were ranged between (42.55) during August which classified as mesotrophic, and 38.69 in February which classified as oligotrophic, AL - Burgah station were evaluated as oligotrophic and values ranged from 39.45 during January and 25.6 during October. The rate of trophic state index were 43.14 , 42.68 , 40.24 and 32.24 for four stations, respectively. Study areas marsh were classified as mesotrophic (39.57).Organic pollution index were measured depending on three variables, namely nitrates, phosphorus and biological oxygen demand to determine the levels of organic pollution for study stations, and to assess the general level of the study area, The values ranged (43.91 - 82.68) at Al - Mndhuri station during the months of May and August, while ranged between (37.65 - 75.76) during the months of November and August for the Al Daoudi station, and values for Al - Zerki station were ranged between (27.88 - 52.51) during the months of October and August respectively, while at AL - Burgah station were (24.60 - 39.22) during September and February.Al - Mndhuri and Al - Daoudi stations were classified in general to be Deteriorated, While stations Al - Zerki and AL - Burgah were classified as Medium, with an annual rate (52.81, 50.29, 38.57, 32.17) for the four stations, respectively. The lower values at Al - Zerki and AL - Burgah stations wasCassociated with decline in values of different factor that used for measuring OPI due to the presence of aquatic plant with high density which acting as filters for water contributed to the improvement of the environmental situation of the study area.Two Laboratory experiments for Free surfaces system static and recycling was done, both of which had lasted for eleven days to compare the efficiency between Epiphytic algae, and T.domingenesis in removing nutrients, which included nitrates and phosphates as well as the reduction of biological oxygen demand. The percentages of removal were calculated for each two days, also the total percentages of removal were calculated at the end of the experiment.Results showed that Epiphytic algae have higher efficiency in removing of nitrates, phosphorus and in reduction biological oxygen demand. than T.domingenesis and at both systems static and recycling. The total percentages of removing nitrate , phosphate and reduction in biological oxygen demand by epiphytic algae were (60.0, 52.91,60.0)% respectively, at the static system, and (68.84, 57.61 , 68.91 )%, respectively, using recycling system, while the total percentages reduction using the aquatic plant for nitrate ,phosphate and biological - oxygen demand were (39.9, 21.42, 63.64)%, respectively, using static system, and ( 48.12, 31.42, 72.87)% respectively, using recycling system. The results showed that the reduction of nutrient by using recycling system is higher than a static system .

Five sampling stations were chosen. Ecological diversity indices were adopted, with a focus on the dietary relations among species of fish larvae and the possibility of dietary overlap within larvae. Two sampling methods were adopted to collect the samples, plankton nets with mesh sizes 100 - 300µm and a wooden quadrate to collect aquatic plants that may exist upon fish eggs and larvae. Water temperature of the studied area ranged form 11.2ºC in January to 33 ºC in August. Salinity ranged form 1.81‰ in December to 3.3‰ in August. Light penetration ranged from 20 cm in July to 150 cm in January. A total of 360 samples were collected, 72 samples from each station. These samples included 7220 fish eggs belonged to three families and 7360 fish larvae belonged to five fish families. The eggs were identified Cyprinidae included Cyprinus carpio and Carassuis auratus, Mugilidae (Liza abu) and Cyprinodontidae (Aphanius sp.). The eggs of L. abu were prevailed at stations 1,3 and 4, and the eggs of C. carpio and C. auratus at stations 2 and 5. The eggs of C. carpio , C. auratus and L. abu were presented in four months ( February - May), and Aphanius sp. from April to July with peak during April. The eggs of L. abu , C. carpio and C. auratus were most abundant during March. Larvae were classified into five families included. Cyprinidae, which included the larvae of C. carpio , C. auratus and A. mossulensis, whereas, Mugilidae included a single species ( L. abu), and Cyprinodontidae, where the larvae were classified to the species level Aphanius sp., Clupeidae represented by Tenualosa ilisha, and Hemiramphidae by Hemiramphus sp.. Larvae of L. abu prevailed on other species in the five stations, and the larvae of C. carpio came in second place in the stations 1,2 and 3. Larvae of Aphanius sp. Occupied second place in station 3 and the larvae of T. ilisha in the second place in station 5. Larvae of T. ilisha appeared during six months (March, April and June to August ) with peak during August in station 4, while the larvae of Aphanius sp occurred at five months (April to August), with peak during April in station 3. The larvae of L. abu , C. carpio and C. auratus occurred in four months ( March to May) , with peak in total number during March at station 3, for L. abu and C. auratus and at station 1 for C. carpio. Larvae of Hemiramphus sp. appeared in August at station 5. The abundance of fish eggs and larvae collected from aquatic plants more than provided by using plankton net, as indicated by the results of statistical analysis there were significant differences between station 1 and stations 2,3,4 and 5 in abundance of fish eggs and larvae which were collected by plankton net, and between station 3 and stations 1, 2 and 5 in the abundance of fish larvae collected from aquatic plant. The diversity index (H') for fish larvae ranged between 0 - 1.068, while the richness index (D) ranged between 0 - 0.884 and the evenness index (J) between 0 - 0.739. Cluster analysis show that the highest similarity in the number of fish larvae between station 2 and stations 3, 2 and stations 4, stations 3 and 4. The highest similarity in the total number fish larvae was found between stations 1 and 5, according the Schoener index. The diet analysis was assessed using points and frequency of occurrence methods. No empty larval stomach were recorded during the study period and there is a high feeding activity and feeding intensity. The result of analyzing stomach contents indicated that the fish larvae were generalized feeders, consumed diatom, algae, detritus, copepoda, daphnia and eggs of molluscs. The larvae of C. carpio and C. auratus feed on diatom, while A. mossulensis, Aphanius sp. and T. ilisha on copepoda. The diversity index of gut content ranged form 1.731 for L. abu to 0.762 for C. carpio. The fish larvae differ in intensity of diet overlap depending on the nature of nutrition, and nine significance diet overlaps between larvae were detected. The significance overlaps ranged form 67.10% to 91.73 %. The highest diet overlap (91.73%) between C. carpio and C. auratus. A very strong diet overlap (101.22) between A. mossulensis and Aphanius sp.. No diet overlap were detected between the larvae of C. carpio, C. auratus, T. ilisha, Aphanius sp and A. mossulensis. The study showed the importance of the northern part of the Shatt Al - Arab River as a breeding and nursery ground for some fish
