Abstract

The HISTOPATHOLOGY of some important organs of perch (Sander lucioperca) and salmon (Salmo trutta caspius) were studied in the southern part of the CASPIAN SEA with emphasis on pollutants. Twenty perch and salmon individuals were captured from the southern region of the CASPIAN SEA, immediately subjected to sampling of the liver, kidney, gills, gonads and muscles which were fixed in 10% formalin. Five mm microscopic slides were prepared from the fixed samples using standard histological methods, and then studied under light microscope.Swelling, hypertrophy and hyperplasia, fusion of secondary lamellae and also congestion, hemorrhage and necrosis of the lamellae were observed in the gill of perch and salmon samples. Congestion, hemorrhage, degeneration and necrosis of the tubules, glomeruli and interstitial tissue of the kidney of the examined fishes were the most important observed signs. Histopathologic signs such as congestion and hemorrhage of the blood vessels, dilation and congestion of the sinusoids, hypertrophy, degeneration and vacuolation of hepatocytes and also necrosis of the liver tissue were the most obvious signs in the liver of the examined fishes. No pathological changes were seen in gonads and muscles. The results showed that the important organs of the studied fish have serious disorders and abnormal conditions, which could be due to the long term exposure to the toxic materials. In terms of public health, higher than standard levels of pollutants in fish body makes them unsuitable for human consumption.
