Effect of Varying Ambiences on Glutathione Concentration in Tissues of Labeo rohita&Clarias batrachus

In these research studies, Effect of varying ambiences on glutathione concentration in tissues of Labeo rohita& Clarias batrachus under a contaminated aquatic environment were evaluated. 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 from all seasons that is moderate, extreme cold, extreme hot and moist warm ambiences. The mean values of glutathione 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 glutathione in fishes of Thadoli area indicated the presence of oxidative stress. In each area, the glutathione activity significantly differed among all the tissues collected i. e. heart, kidney, liver and gills. In each area, the activity of glutathione was highest in liver for both the fishes.
