Salinity tolerance in Labeo rohita (Hamilton 1822) fingerling was conducted for 96 h using a static, non-renewal system and LC50 determined for 48 and 96 h exposure were 9.60 and 7.72‰ with standard deviation 9.27-9.93 and 7.41-8.03‰, respectively. For sublethal study, 0, 2.5, 3.5 and 4.5‰ were selected to assess the chronic effect of salinity on this species. At the end of 90 days of exposure, it was found that the average weight gain was maximum at 0‰ followed by 2.5‰, then 3.5‰ and the least at 4.5‰. Similarly, highest mortality (43.75%) was recorded in fishes exposed to 4.5‰ salinity and least (12.5%) at 2.5‰ at the end of 90 days of experiment. On termination of the experiment, ascorbic acid level was found significantly reduced (p
