Abstract

The research was aimed to determine the production performance of white shrimp on different stocking densities. The experiment was conducted by using 9 ponds and treated with densities of (100, 200 and 300) shrimp m-2 with three replications. Feeding with 30% protein content of 3% biomass day-1 was given 4 times. The collected parameters consisted of water physical-chemical as well as shrimp biological aspects. Parameters such as temperature, transparency, pH, DO and salinity were observed daily, whereas nitrate, nitrite, ammonia and TOM and shrimp biological parameters were observed every 2 weeks. Physical and chemical data were analyzed descriptively, while growth data, survival rate, FCR and production biomass were analyzed by one-way ANOVA. The result showed that the growth rate was 0.1138 g day-1 to 0.1655 g day-1, the composition of the length and weight class consisted of small, medium and large. The survival rate was 61.75% -97.99%, the final weight was (9.58-12.93) g shrimp-1, FCR was 1.00-2.00 and biomass production was (14.99-22.37) kg m-2. Stocking densities affected to growth, survival, FCR and biomass production (P<0.05). Growth and survival rate decreased with increasing density, whereas biomass production was significantly different between all treatments. Low density can be applied to white shrimp farming in sand farms using mulch
