ABSTRACT

In the present study, Oreochromis niloticus was exposed to one fourth of 24 h LC50 of malathion malathion (1.42 ppm), chlorpyrifos (0.125 ppm) and lambda-cyhalothrin ( 0.0039 ppm) for 24 and 48 h and then total protein was estimated in the brain, gills and muscle tissues. Significant (p< 0.005- 0.00) decreased in total protein was noted in response to all the pesticides as compared to control group and a slight increase was also noted during 48 h as compared to 24 h. The level of total protein was decreased for pesticides in order of chlorpyrifos>malathion> lambda-cyhalothrin during the exposure period.
