Abstract
Static acute (96 h) bioassays were conducted on the spawn (4.0 mm) and the fry (15.5
mm) of freshwater fish Channa gachua (Ham) and the median lethal toxicity (96 h LC ,)
of the pesticide endosulfan on the fish were estimated as 9.0 ppm and 22.0 ppm, respectively.
When the fishes were exposed from spawn stage up to a period of 30 days in three sublethal
concentrations viz. 0.01, 0.02 and 0.05 TU, there was an overall reduction in growth of the
fish. While the reduction of growth was greater (up to 58.9%) at 0.05 TU, it was minimum
(11.64%) at the medium sublethal concentration of 0.02 TU at the end of 30 days of
experimental tenure
