Abstract
Abstract The study was aimed to evaluate the growth, survival rate and production of white shrimp ( L. vannamei ) culture under different stocking density in controlled tank. This research was conducted at Experimental Pond Installation. Research Institute for Coastal Aquaculture and Fisheries Extension in Maros Regency, South Sulawesi. Indonesia. Juveniles of white shrimp size in weight 0.14 g/ind were cultured for 70 days in three different stocking densities: 100, 200 and 300 ind/m 3 in a total of nine fibre tanks sized of 2 m 3 . The study used Completely Randomized Design (CRD). with three replications for each treatment. The parameters observed were growth rate, survival rate, production, feed conversion ratio of white shrimp and water quality condition. The results showed that the different stocking density had a significant effect (P <0.05) on growth, survival rate and production of white shrimp. The final weight and absolute weight of vaname shrimp decreased as density increased to 300 ind/ m 3 . The final weight of vaname shrimp in treatments A. B and C were 13.70 g/ind, 12.27 g/ind and 10.90 g/ind respectively. Survival rate and production of white shrimp in this study ranged from 80-95% and 1.24-2.42 kg/m 3 respectively. Water quality measured during the experiment was suitable for the growth of white shrimp.
