This study aimed to determine shrimp performance such as growth, survival rate and biomass production of the whiteleg shrimp (Litopenaeus vannamei) cultured in sandy ponds using plastic mulch and different densities (100, 200 and 300 shrimp m-2). The experiment was conducted using 9 ponds of 3x4x1 m (12 m3). Experiments were designed in 3 different stocking densities as treatments and repeated 3 times.
Shrimps were cultured in a period of 75 days by measuring daily growth, survival rate (SR), food conversion ratio (FCR), and biomass production. The water quality on daily temperature, pH, salinity, DO and transparency, nitrite, ammonia, and TOM were observed every two weeks. Post larvae (PL9) L. vannamei was fed with 30% protein powder and crumbs fed 4 times per day. Water refreshment was done periodically at the time of filling. Observations were conducted on final weight, daily growth, survival rate, FCR, and biomass production using ANOVA uni-variate analysis. The final weight of 9.58-12.93 g, survival rate between 61.75-97.99%, daily growth between 0.1138-0.1655 g, FCR between 0.92 and 2.06 and biomass
production 14.99-22.37 kg m-2 were recorded. Density affects growth, SR, FCR, and biomass production of shrimp (P<0.05). Growth decreased with increasing density (P<0.05), survival decreased with increasing density (P<0.05), while biomass production was significantly different between all treatments (P<0.05).
Low density can be applied to aquaculture L. vannamei in sandy ponds using mulch. |
