Laboratory analysis was made to check the toxicological effect of cypermethrin on fresh water catfish (Clarias batrachus). Exposure of (LC 50) sub-lethal dose of cypermethrin resulted significant alterations in protein content in various tissues of fish. At sub-lethal concentration cypermethrin resulted alterations in total protein, as in muscles (-13.95%), in liver (-27.58%), in intestine (-16.88%) and in gills (-13.72%). Highest reduction of protein content level was recorded (-27.58%) in liver 0.029 μl/100mg dry weight. Cypermethrin has shown strong piscicidal capacity against selected catfish and adversely affected the protein content.
