The present study evaluated the effect of stocking density on growth and survival of post larvae (PL) of Fenneropenaeus merguiensis (de Man, 1888), commonly known as banana shrimp. PL was stocked at four different densities i.e., 10, 20, 30 and 40/m2 (T10, T20, T30 and T40, respectively) and reared for a period of 60 days. Water quality and growth performance parameters of different treatments were compared during the experiment. A significant (p<0.05) decrease in dissolved oxygen (DO) concentration relative with the higher stocking density was observed. Though some of the parameters showed significant (p<0.05) difference among the treatments, the water quality remained within safe level, throughout the experiment. Increase in stocking density led to significant reduction (p<0.05) in BWG and SGR of PL. The highest value of FCR was in T40 and lowest in T10. Stocking density also showed an inverse relationship with survival percentage of shrimp. Results of the present study revealed that high stocking density (≥30/m2) can seriously impair the growth of F. merguiensis PL.
