Abstract
The aim of the present study is to evaluate the effect of sub-lethal effect of cypermethrin on different adenylate nucleotides in various tissues of Channa striatus. It has been observed that the levels of ATP, ADP and energy charge elevated at 24 hours relative to control in all the organs. But their levels declined through 7 and 15 days exposure periods. The percent of suppression is high at 15 days exposure period. From 15th day onwards their level gradually elevated and came nearer to control at 30 day exposure period and the values were found to be significant. In case of AMP it has been observed that AMP declined at 24 hours relative to control in all the organs. But their levels elevated gradually through 7 day and continued upto 15 days exposure period. From 15th day onwards levels of AMP gradually declined and came nearer to control at 30 day exposure period and the values were found to be significant at (P< 0.001). Hence from the results of present study it can be concluded that cypermethrin was shown significant toxic effect on adenylate nucleotides in various tissues of C. striatus.
