The cypermethrin (synthetic pyrethroids) has shows strong piscicidal activity in freshwater teleost fish Colisa fasciatus for all the exposure periods (24h or 96h) in time as well as dose dependent manner. The LC values decreases from 0.009 (24h) to 0.006 (96h) in winter season (water temp. 16°C) and 0.06 (24h) to 50 0.02 (96h) in summer season (water temp. 28°C). Sub-lethal doses (40 and 60% o...
