Physiological effects of acute lindane exposure on Clarias gariepinus, juveniles

Abstract

Juveniles of Clarias gariepinus, of mean weight 32.54g+ 0.37 were exposed to five different concentrations of Lindane including the control (O.OOµp/L, 2. 5µg/L, 3.75µp/L, 5.00up/L and 6.25ug/l) using static method in aquaria tanks under Laboratory conditions for a period of 96hours (four days)acute exposure. The 96hr LC 50 was found to be 3.5&#181g/L. Observed symptoms of acute exposure to Lindane include agitated swimming and jumping, loss of balance, quiescence and death.
