Abstract :
Lipid peroxidation is one of the several physiological mechanisms of the organism by which reactive oxygen species (ROS) may be released which is toxic to cells and tissues. In general, the formation of lipid peroxidation products in tissues may infer the extent of oxidative damage and decline in anti-oxidant defense mechanism. In the present investigation, lipid peroxidation products were measured by determining the malondialdehyde (MDA) concentrations in the tissues of control and exposed fry of Labeo rohita and Cyprinus carpio. The fish fry were exposed to their sub lethal concentration of cadmium (1/5th of 96hrs LC50 i.e., 0.1998ppm for Labeo rohita fry and 4.98ppm for Cyprinus carpio fry respectively) for a period of 20days. Parallel controls were maintained without metal toxicant throughout the experimental period. Samples were collected both from control and exposed fish fry of each species at intervals of 24hrs, 48hrs, 96hrs, 10days and 20days for the estimation of lipid peroxidation products. A maximum amount of lipid peroxidation products was observed at 20 days exposure (3.01n moles of MDA/gm wt of the tissue in Labeo rohita fry and 2.7029 n moles of MDA/gm wt of the tissues in Cyprinus carpio fry). From the data, it was known that more amount of the lipid peroxidation products are found in the fry of Labeo rohita exposed to cadmium than in the fry of Cyprinus carpio indicating the fry of Labeo rohita is more sensitive than Cyprinus carpio.
