Stocking density is important parameter in fish production. It has direct effects on growth and survival of the fishes which finally affect the fish production. In present investigation, different stocking densities (5000, 7500, 10,000 and 12,500 No./ha) in Halwana leaves based diet were evaluated to know the influence on growth and net production of grass carp. Best growth in terms of average length was recorded in T1 (5000 no./ha stocking density) (39.34 cm), followed by T2 (7500 no./ha stocking density) (37.75 cm) T3, (10,000 no./ha stocking density) (35.60 cm) and T4 (12,500 no./ha stocking density) (33.02 cm) but no significant change in the average length was observed among different stocking densities. Best growth in terms of average weight was observed in T1 (5000 no./ha stocking density) (212.68 g) followed by T2 (7500 no./ha stocking density) (205.34 g), T3 (10000 no./ha stocking density) (199.35 g) and T4 (12500 no./ha stocking density) (179.39 g) respectively (Table 2). The study indicated that, stocking density from 5000 to 12500 fish/ha does not affect significantly on average weight of the grass carp but weight was slightly decreased with increasing stocking density. The net production was significantly higher in T3-10000 (3522.04 g/18m2) followed by T4-12500 (3229.02 g/18m2) and T2-7500 (2737.86 g/18m2).
