Alteration of lipid content in the fresh water carp, Cyprinus carpio under the toxic stress of industrial effluent

Abstract

Contamination of aquatic ecosystems by industrial effluents causes harmful effects on health, growth, survival of aquatic animals like fishes which serves as a useful model for assessing the effect of chemicals mixed in the aquatic environment. Present study investigated the effect of sub-lethal concentrations (1.5%, 2 and 2.5%) of the treated textile bleaching effluent on the total lipid content in muscle, gill, liver and intestine of Cyprinus carpioafter exposure to 28 days. A significant decrement in total lipid content suggested that lipid might have utilized for the energy demand under the condition of stress.
