Abstract:
اجريت الدراسة الحالية في اربعة انهار ضمن محافظة القادسية هي نهرالديوانية والشامية والحمزة وعفك, اذ جمعت 945 سمكة تعود لنوعين من الاسماك هما الشبوط الاعتيادي Barbus grypus والخشني Liza abu وبعــد فحصها وجـد ان 205 سمكة مـن اسماك الشبوط الاعتيادي و344 سمكة | The present study has been conducted in four parts of AL - Qadisiya (Diwaniya center, Shamiya, Hamza and Afaq). A sample of 945 fish of Barbus grypus and Liza abu has been examined. It was found that 205 of the Barbus grypus fish and 344 of the Liza abu were infected with parasitic intestinal worms. Some parasitic intestinal worms have been detected such as the Neoechinorynchus iraqensis in both fish types. The female paulisentus in Barbus grypus, Bothriocephalus acheilognathi were found in both Barbus grypus, Liza abu and the larva of Contracaecum spp was seen in the Liza abu and Barbus grypus type. In Diwaniya river had high infection of both fish types was 61.31%. The Barbus grypus fish were recorded with 70.11% while the Liza abu fish infection was 57.21%.. In Hamza river the total percentage of infection was 56.79 % in both types. The Liza abu infection in the four parts of Diwaniya as 56.30%. In September the infection percentage was higher by 63.21% in the two kinds of fish. while in February, December the infection rate was as low as 50%. It was also found that length categories of (26 - 24.1)cm of Barbus grypus had high percentage of 67.16%, while the length category (28 - 26.1) cm suffered 64.47% infection with intestinal worms in the length category (> - 30.1) was 22.22%.As for the Liza abu it had a high percentage of infection in length category (12 - 10.1) cm, the percentage was 67.53% and dropped to 46.53% in length category (8 - 6)cm.The present study has discovered many pathological changes (visable and microscopic)caused by the intestinal worms, Among the visable changes was embolism and bleeding of the walls of the infected intestinal microscopic changes included an increase in the phlogistic and phagocytic cell and ruining of the internal tissue lining the intestines and atrophy villi.Eight heavy metals were measured.They included Cadmium, Lead, Zinc, Nickel, Copper, Manganese, Mercuryand Chromiumby means of an atomic absorption spectrophotometer tissues from the a forementioned types of fish were measured for these heavy metals these tissues were from the liver, muscles, gills, two kinds of intestinal worms (Cestode and Nematode) were measured also water and sediments (deposits) from four districts of Diwaniya throughout the year, Cadmium registered high concentrations in autumn (12.67) Mg/ gm in the liver of the Barbus grypus. lower concentrations of Cadmium were registered in Winter (1.30) Mg/ gm in the liver of Liza abu.The Barbus grypus livers had high concentrations of lead in autumn (21.03) Mg/ gm in Hamza rivers, where as gills of the Liza abu registered lower concentrations(6.43) Mg/gm in spring.The livers of the Barbus grypus registered high concentrations of zine in autumn which where (32.27)Mg/ gm in Hamza river. Shamiya river they dropped to 21.17 Mg/ gm in spring, It was observed that Nickel had high concentrations in the livers of both fish types, The highest of which was in autumn, the the Hamza river had the highest concentrations in autumn which were (29.17, 28.63, 27.67) Mg/gm.In spring the nickel concentrations were low in the gills of the Liza abu11.10 Mg/ gm in Shamiya river, The livers of the Barbus grypus had the most concentrations of copper which reached 2.02 Mg/ gm while livers of the Liza abu had 1.92 Mg/ gm concentrations in autumn in Hamza river.Manganese showed low concentrations in the Liza abu gills in winter and spring they ranged (1.67, 1.73) in Shamiya river, manganese concentrations increased in autumn and summer to reach (14.83, 10.07) Mg/ gm in the Liza abu liver and (15.13, 10.57) Mg/ gm in the muscles of the Barbus grypus in Hamza river, Marcury had the lowest concentrations 24.37 Mg/ gm in the gills of Liza abu in Afaq river, It was observed that the livers of the Barbus grypus were more vulnerable, the highest concentrations was registered 49.97 Mg/ gm in Hamza river followed by Diwaniya which registered 48.97 Mg/m in autumn. Chromium registered lowest concentrations compared to the other metals,.cestodes isolated from the Barbus grypus registered high of mercury concentrations that reached 37.667 and 37.300 Mg/ gm in Hamza and Diwaniya rivers, chrome concentrations was low in the tape worms 0.166 Mg/ gm while nematodes, the concentrations was 0.157 Mg/ gm in Shamiya river.cestoda and nematodais isolated from the intestines of Liza abu registered high concentrations in autumn, cestoda had the most of the concentrations of heavy metals, Mercury and nickel had high concentrations of (35.783, 25.840) Mg/gm, copper and chrome had lower concentrations(1.881, 0.174) Mg/gm inHamza river, nematode registered high concentrations that reached 33.994 Mg/ gm in mercury in Hamza river.As for the rivers sediments Autumn was the most effected by heavy metals for the sediments in Hamza river had high concentrations in Manganese, mercury, and chrome (367, 376.97, 290.93) Mg/ gm respectively while the lowest concentrations was for copper 22.53 Microgram/gram in Shamiya river in spring. The rivers water registered low concentrations of heavy metals in spring, The Shamiya river had low concentrations of lead and cadmium (80.57, 54.60) Mg/gm, autumn registered higher concentrations compared to spring where the highest concentration of manganese and Copper was (512.37, 442.83) Mg / gm in Hamza river.
