Changes in total protein in liver and kidney of freshwater fish, Channa punctatus (Bloch.) After intoxication of carbaryl
Pesticides are one group of toxic compounds linked to human use that have a profound effect on aquatic fauna. Fish may be good indicators of contamination by pollutants because their biochemical responses are quite similar to those found in mammals. Studies on toxic effects of carbaryl (a carbamate pesticide) on liver and kidney in freshwater fish Channa punctatus have been made. The LC50 value of Carbaryl was calculated 10.05mg/l for various time periods 24, 48, 72 and 96 hrs. The study was conducted to investigate the total protein changes in the liver and kidney of freshwater fish, Channa punctatus exposed to different sublethal concentrations of pesticide carbaryl for a period of 15, 30, 45, 60, 75 and up to 90 days. Carbaryl intoxication in Channa punctatus caused significant decrease in total protein in liver and kidney as compared to control. The reasons for such changes have been discussed in this paper.
