Studies on Morphological Effect of Some Pesticides on Fresh Water Fish, Labeo rohita in Sai River of Jaunpur District, Uttar Pradesh, India

Pesticides are one of the potentially harmful toxic chemicals introduced into the aquatic environment. Fish serve as important bio-indicators for aquatic life. Widely used pesticides formulation two investigate possible chemical biological and toxicological effects of pesticides that may enter into our eco-system. Effects of pesticides (herbicides insecticides, rodenticides and fungicides) to loss protein content of the liver gill and intestinal tissue of the fresh water fish, Labeorohita.The Recent study is aimed two assess the toxicological impacts of treated and untreated effluents on aquatic fresh water fish, Labeo rohita. The Most common edible fish having diverse characters includes difference in morphology, food and feeding etc. Symptoms were nearly identical on various host spp (Labeo rohita. with respect to behaviour of the infected fish. The toxicity of pesticides to an organism is usualy expressed in terms of the LD50 (lethal dose 50 percent) and LC50 (50 percent lethal concentration) observed the behavioural studies of exposed to Labeorohita. Therefore, the protection and prevention of aquatic ecosystem will be possible only with the appropriate and rationalized application of pesticides.
