The present study deals with the toxicity of common mixed effluent of SIPCOT Industrial Estate on
histopathological changes of gills and biochemical changes in gills, hepatopancreas and muscle of an important
estuarine fish Lates calcarifer. When fish was exposed to 10, 15 and 20% effluent concentrations, alteration
in the structure of gills was observed. In fish exposed to 10% concentration, swelling, hyperplasia, hypertrophy
and proliferation of chloride cells of gills were observed, but in 15% effluent, lifting up of the epithelium and
lamellar fusions were seen. In 20% effluent treated fishes, disintegration of epithelial cells, desquamated
epithelium, haemorrhage and complete damage of epithelial cells of both primary and secondary lamellae w ere
observed. Overall reduction in total protein, total DNA, total RNA, glycogen content, protein bound sugars and
total lipid of gills, hepatopancreas, and muscle was observed. The biochemical changes were higher in 20%
effluent treated fish than that of 15 and 10% effluent treated fish. The result of the present study recommends
proper dilution of the effluent before its discharge.
Key words: Biochemical changes, effluent, fish, histopathology, , ,
