Abstract : Organochlorine pesticide (Aldrin) and Organophosphate pesticide (Cythion) that are used by farmers in field move with run off water and erosion from treated area to nearby waterbodies . Bio-magnification of these pesticides in waterbodies adversely affect the physiology of fishes and other fauna. Aldrin and Cythion pesticide intoxications adversely affect the liver glycogencontent in both the sexes of the test fish. The value of liver glycogen is found high in male of all the three experimental conditions during all the three annual reproductive periods, prebreeding, breeding and postbreeding periods. Liver glycogen is found high in control condition followed by semilethal and sublethal
conditions during annual reproductive cycle. When seasonal variations are taken into account, high liver glycogen content is found during breeding period followed by prebreeding and postbreeding periods.
