Vaname Shrimp Cultivation (Litopenaeus vannamei) on High Stocking Densities in Controlled Ponds

Andi Gusti Tantu, Suryawati Salam, Muhammad Ishak

Efforts to increase the productivity of ponds can be done by increasing stocking densities accompanied by providing excellent input and adequate technological support. Three stocking densities are 750; 1,000; and 1,250 individu/ m², applied to ponds with an area of 1,600 m² with water depth of 2.0 m, equipped with aeration systems in the form of windmills and root blowers, submersible pumps, automatic feeders, central drain and collector drain as well as wastewater treatment plants. The capacity of the aeration system is 500 kg of shrimp/HP biomass. Shrimp kept for 110 days. The results showed that the stocking density applied resulted in a final shrimp weight which was relatively the same range 15.50-16.45 (15.60 ± 0.40) g/individual with a daily growth value of 0.165-0.185 (0.17 ± 0.01) g/day. The production obtained is 13,714 kg; 18,285 kg; and 21,942 kg. Value of feed conversion ratio 1.42, 1.39, 1.54 and electricity needs 3.21, 2.53, 2.42 kw/kg of shrimp and 2.25 water requirements, 1.65, 1.63 m³/kg shrimp. The lowest shrimp production cost is IDR. 30,526/kg of shrimp on a stocking density of 1,000 individu/ m² with an operating profit of IDR 585,142,857.14/year. The stocking density of 1,000 individu/m² produces better performance, so it is recommended to be a reference for high stocking densities for vaname shrimp farming.
