Abstract

Pollution may be defined as fouling of the environment. It is an undesirable change in the physical, chemical or biological characteristics of the land, air and water that may or will harmfully affect human life or that of desirable species. The physiological, biochemical and histological changes in Mystus gulio after exposure to sublethal concentrations of the dairy industry effluent have been investigated. The physiological and biochemical changes in Mystus gulio after exposure to sublethal concentrations of the textile industry effluent have been investigated for the period of 21 days. Two different concentrations of textile industry effluents were used to carry out the experiment viz 25 cm3/dm3 and 50 cm3/dm3. The results of physiological and biochemical changes in muscles and blood of Mystus gulio showed that, fish were under considerable stress during the exposure periods to the sublethal doses. The results obtained in the present study showed that, the industrial effluents from textile caused marked depletion in the biochemical composition of muscles and blood parameters of fish Mystus gulio after the exposure period. The biochemical changes, protein, lipid and carbohydrate were recorded.
