The present experiment evaluated the effect of different levels of salinities on growth and survival of post larvae (PL) of Fenneropenaeus indicus, commonly known as Indian white shrimp. PL was stocked at six different salinities levels i.e., 15, 20, 25, 30 35 and 40 ppt (T1, T2, T3 T4, T5 and T6, respectively) and reared for a period of 60 days. Water quality parameters and growth performance parameters of different treatments were compared during the experiment. A significant (p<0.05) decrease in growth and survival concentration relative with the higher and lower salinities level was observed. Though some of the parameters showed significant (p<0.05) difference among the treatments, the water quality remained within optimum level, throughout the experiment. Increase in salinity levels led to significant reduction (p<0.05) in ABW and survival of PL. Treatment T3 (water salinity 25 ppt) and treatment T4 (water salinity 30 ppt) were found at par with each other and significantly better than rest of the treatments in all the periods barring “0” DOC. T3 and T4 recorded higher mean body weight at 60 DOC during both the years 2016-17 (0.427 and 0.402 g), 2017-18 (0.577 and 0.505 g) as well as in pooled results (0.502 g and 0.454g) as compared to rest of the treatments. Survival rate of treatment T4 was significantly higher than other treatments while lowest survival was found in treatment T1 and T6.
