The objective of this study was to provide some valuable information to the field of freshwater fish determination levels of biochemical parameters of Labeo rohita & Clarius batrachus which living in natural environment. Present study was conducted on Bisalpur reservoir. . Four areas related to Bisalpur reservoir selected were Bisalpur, Nasirda, Thadoli and negadiya for collection of fishes as well as water samples.Total 80 fishes collected during extreme cold condition when water bodies were having peak environmental contamination in reservoir due to fall in water level and feeble current. From each area 20 fishes were collected which constituted Clarias batrachus (10) and Labeo rohita(10). The mean values of vitamin A in all the tissues were significantly lower in Thadoli area, followed by Negdiya and Nasirda. The highest values were obtained in Bisalpur area. In Thdoli area concentration of dissolved oxygen was highest. Lower concentration of vitamin A in fishes of Thadoli area indicated the presence of oxidative stress.

Vitamin A, Oxidative stress, Clarias batrachus and Labeo rohita.
