Hematopoetic alterations induced by lindane on the Indian freshwater cat fish, Clarias batrachus (Osteichthyes: Clariidae).

The effect of organochlorine insecticide, lindane on Indian fresh water cat fish species, Clarias batrachus was investigated in fresh water at 25–30 dergree centrigrade under laboratory condition. Three sublethal concentrations of lindane (hexachlorocyclohexane) were prepared as 0.4mg/L, 0.6mg/L and 0.8mg/L. The LC 50 (96 hour exposure) value was found to be 0.98mg/L. The results indicate the lowering of Hb%, total RBC count and GSI of fishes under treatment whereas the increased WBC count is recorded in the treated.
