Abstract

Para-Nonylphenol(NP) is an organic phenolic compound present in the domestic and most of the industrial discharges. It has extensive impact on the plants and animals. However, fish is highly responsive aquatic vertebrate as far as toxic effects of poisonous substances are concerned. When the fish was exposed to low concentration of NP it does not showed any behavioural changes ut, when the concentrations were gradually increased fish started showing the sign of distress. In the Present study the lethal concentration of p-Nonylphenol was calculated to be 15.51 ppm and beyond 16.50 ppm Channa punctatus exhibited 100% mortality. The linear regression values obtained is y=20.32x-263.29. The coefficient correlation obtained is R2=0.7139. Throughout the experimental tenure the pH and temperature of water was maintained to get rid of its impact towards mortality of fish.
