Endosulfan mediated some physiological and biochemical changes in a fresh water fish
Abstract
In the present study, an attempt has been made to analyze the toxicity of the endosufan on fresh water fish Labeo rohita (Rohu). It has been found that the acid phosphomonoesterase activity was decreased by 23.78% in liver, 17.93% in muscles, 16.97% in kidney and 44.31% in gills of Labeo rohita at 0.25 ppm of Endosulfan after an exposure of 15 days. The toxicity of a pesticide could vary from species to species. The alkaline phosphomonoesterase activity in Labeo was reduced by 26.15% in liver, 23.24% in muscles, 2.25% in kidney and 2.18% in gills. Exposure of endosulfan caused significant change by descreasing the lipase activity of Labeo fish. The maximum reduction was 57.74% in muscle and 52.28% in liver. The minimum change in lipase activity was 3.74% and 5.65% in gills and kidney respectively. Choline esterase activity was reduced by 35.66% in liver and 38.60% in muscles and the maximum decrease 52.54% in gills and 41.21% in kidney. Endosulfan caused 30.79%, 55.59%, 41.21% and 52.54% decrease in the activity of Trypsin in liver, muscle, kidney and gills respectively. It caused significant changes in glycogen content in liver, muscle, kidney and gills of the fish. The maximum reduction of glycogen was was noted (43.53%) in liver and minimum (26.13%) in gills. Protein concentration was reduced by 22.89% in liver, 31.81% in muscles, 43.94% in kidney and 26.22% in gills. The maximum decrease in total lipids founds were 3.095% in liver, 2.73% in muscles, 0.21% in kidney and 2.64% in gills. Therefore it can be said that these are the biochemical changes in fish when exposed to the sublethal concentration of the pesticide and it also showed irritation, very fast movements of operculum, violent action of pelvic fins and spreading of the fins.
