Abstract
Channa punctatus were exposed for 24, 48, 72 and 96 h to sub-lethal concentration (30% of LC50 for 96h) of carbaryl and cartap (carbamate pesticides) in order to record their effect on total lipid and cholesterol contents in liver, kidney and gills. The normal lipid content in liver, kidney and gills ranged from 17.95±0.41 to18.21±0.38 mg/g, 15.55i-0.51 to16.21±0.35 mg/g and 8.53±0.39 to 9.58±0.33 mg/g, whereas cholesterol contents varied between 3.60±0.06 to 3.81±0.04 mg/g, 1.61±0.05 to 1.72±0.02 mg/g and 0.71±0.02 to 0.77±0.10 mg/g, respectively. The treatment elicited significant decline in lipid and cholesterol contents throughout the exposure period suggesting response of the fish to the pesticide intoxication.
