dc.description.abstractThe effect of different feeding rates on the production and profitability of Phases 1 and 2 (3-week each) nursery culture of hatchery-produced crab Scylla serrata was determined. Minced mussel meat and formulated diet (at a ratio of 30:70) were fed to crabs. The crabs were stocked randomly in 12-m2 net cages installed in the nursery earthen pond at stocking densities of 50 m-2 for Phase 1 and 10 m-2 for Phase 2. Crabs were fed three times daily at 0830, 1300 and 1630h h. In Phase 1, feed conversion ratio (FCR) at a feeding rate of 100% of initial crab biomass day-1 for the entire three weeks was the lowest (p<0.05) while survival, body weight (BW), carapace width (CW) and carapace length (CL) were not different (p>0.05) among crabs given different feeding rates. For Phase 2, the feeding rate of 40-30-20% of crab biomass day-1 (week 1-2-3) resulted in lowest (p<0.05) FCR that was not significantly different from FCRs of crabs fed 50-40-30% and 60-50-40% of BW. Crab BW, CW and CL were not different (p>0.05) among feeding rate treatments. Profitability was better when feeding rate used was 100% of initial crab biomass day-1 for the entire Phase 1 or 100-50-40% of crab biomass day-1 (for week 1-2-3). A feeding rate of 50-40-30 % of crab biomass day-1 (week 1-2-3) was more profitable in Phase 2.en
