【 摘 要 】

Experiment was conducted to assess the potential of increasing production of shrimp,Penaeus monodonby enhancing primary production through fertilization and reduc feeding regime. Four treatmentsviz ., T1, feeding @ 2% of shrimp biomass from 31~80 days of culture and then 1%; T2, feeding @ 3% of shrimp biomass from 31~80 days of culture and then 2%; T3, feeding @ 2% of shrimp biomass from 31~80 days of culture and then 1% + fertilization; T4, feeding @ 3% of shrimp biomass from 31~80 days of culture and then 2% + fertilization each with three replications were tested. Urea @1.25 ppm and TSP @ 1.50 ppm were applied as fertilizer monthly. After 120 days of culture, mean final weight of shrimp was 11.86±0.35g, 12.08±0.51g, 13.30±0.99g and 14.50±1.14g with the production of 458.36±14.86 kg/ha, 484.93±7.26kg/ha, 536.75±4.81 kg/ha and 592.19±35.05 kg/ha in T1, T2, T3 and T4, respectively. Reduction of feed reduce both growth and production of shrimp. Increase in primary productivity due to fertilization increase production of shrimp to a significant level (F=32.94; p<0.001). But overall production of shrimp was lower in comparison to other similar studies when higher feeding applied.Bangladesh J. Zool.43 (1): 9-17, 2015
