Abstract

Comprehensive application of pesticides in recent times in agro-farm and public health operation causes a high degree of pollution in aquatic ecosystem. These substances change the water quality that is the habitat of many aquatic organisms. Fishes behave very much sensibly to the changes in their aquatic ecosystem. The study was aimed to determine the toxicity of Carbaryl (1-naphthyl methylcarbamate), a synthetic carbamate pesticide on the freshwater catfish Heteropneustes fossilis. The experiment was conducted under static conditions. The LC50 value of cypermethrin for 24, 48, 72 and 96 h was estimated. Behavioral changes in fish due to carbaryl exposure were regularly monitored for 96 h. Further, the fish were subjected to short term (96 h) exposure of two sub lethal doses (2mg/l & 4mg/l) of the pesticide.
