Biochemical changes induced by dimethoate (Rogor 30% EC) in the gills of fresh water fish Puntius ticto (Hamilton)
The freshwater fish Puntius ticto was exposed to lethal (5.012 ppm) and sublethal (2.506 and 1.253 ppm) concentrations of dimethoate for 96 h and 60 days, respectively. Biochemical changes in the gills were analyzed after exposure period. Exposure of fish to lethal and two sublethal concentration of dimethoate showed decreased in the protein content in the gills after 60 days exposure. As compared to lethal...
