|Abstract:||An onstation trial of banana shrimp, Fenneropenaeus merguiensis was conducted for 130 days in zero water exchange brackishwater ponds at two stocking densities, 10 (T10) and 20 (T20) nos. m-2. Water parameters like total ammonia nitrogen (TAN), NO2-N and NO3-N did not differ significantly (p>0.05) among treatments while T20 had significantly higher (P<0.01) turbidity, PO4-P and significantly lower (P<0.01) dissolved oxygen compared with T10. At the end of grow out period, banana shrimp reached a final average body weight of 14.1±0.84 g in T10 and 11.0±0.14 g in T20 with 50.5 % higher (p<0.05) average productivity in T20 (990±7.07 kg/ha) compared with T10 (658±65.05 kg/ha). Regression trend for length weight analysis indicated that growth exhibited a positive allometric pattern and female showed better condition factor than male in both the treatments. Similar Fulton condition factors observed in both the treatments reflects better feed utilization and suitable culture environment even at higher stocking density. Present findings elucidate the potentials of high density culture of banana shrimp in coastal districts in India.|
