摘要：
Microcystin is a toxin secreted by cyanobacteria, which are the dominant phytoplankton in eutrophic freshwater bodies. The present study reports histopathological, hematological and biochemical changes in the freshwater fish, Heteropneustes fossilis due to toxicity of microcystin. Toxic effects were observed in liver, kidney, corpuscles of Stannius, gills and gonads. Bilirubin concentration increased in the blood of treated fish. Concentration of cholesterol, triglycerides, aspartate aminotransferase and alanine aminotransferase, and alkaline phosphatase was affected due to toxicity. It is suggested that microcystin concentration should be monitored in the drinking water and the public awareness should be created.
