Toxicity effect of atrazine on histology, haematology and biochemical indices of Clarias gariepinus

Abstract

The impact of short term exposure to herbicides, atrazine on Clarias gariepinus juveniles was evaluated using standard methods that assessed fish histology, haematological and biochemical. Histology analysis of the fish organs examined revealed varying degrees of pathological alterations to the gill and liver in the study. The gill of fish showed alterations like thickening of lamella and sloughing off. The liver exhibited changes such as vacuolar degeneration of hepatocytes, hepatocyte swelling and necrosis amongst other were observed. The assessment of biochemical parameters revealed significant increase (p
