ABSTRACT
Malathion has a long range of application in agriculture, which leads its accumulation in animal tissues and may influence
biochemical balance of aquatic organisms. Present study on fish gills and muscles has remarkable potential in understanding
the adverse effect of selected toxicant on the biochemical and structural integrity of tissues. Twelve fingerlings were exposed
to LC50 (406 ìg/L) concentration of malathion over a period of 96hrs. Periodic exposure of malathion at 24th, 48th, 72th and
96th hr, resulted in the form of reduction in gills protein content (-13.99%), (-18.56%), (-33.90%) and (48.14%) respectively.
On other hand, in muscles similar reductive pattern of protein content was recorded as (-8.25 %), (-26.37%), (25.82%) and
(-43.58%). Such negative protein alterations may be used as potential biomarker for pesticide toxicity in fresh water
ecosystem.
