Abstract: A study was undertaken to evaluate the effect of stocking density on brood stock development of mud crab (Scylla serrate) in brackishwater earthen ponds. Four stocking densities such as 6000/ha (T1); 8000/ha (T2); 10000/ha (T3) and 12000/ha (T4) were tested and the crabs were allowed to fed with 50% slaughterhouse+25 percent tilapia (Oriochromis niloticus)+25% soft shrimp head. In terms of survival rate (both male and female) the stocking density having 6000/ha showed the best performance. For female crab significant lower survival (p<0.05) was observed for T3 and T4 compare to T1 and T2. But for final growth and carapace width, an insignificant variation was noted among the treatments. However, in case of T1 and T2, 2.5-3.0 percent of females were found to became berried showing significant variation with other two treatments proved that high stocking has inverse effect on brood development.
