Abstract
Vannamei shrimp ( Litopenaeus vannamei ) is a fishery product that has high economic value. The nature of vaname shrimp that is able to adapt to a wide salinity, causes maintenance to be carried out in low salinity media . The maintenance of vaname shrimp in freshwater media can be a solution to increase the production of vaname shrimp. There are several obstacles in the maintenance of vannamei shrimp in freshwater media including : namely the concentration of dissolved minerals in fresh water is very low so that absorption from the environment cannot be used to fulfill the metabolic needs of freshwater organisms , therefore mineral additions are needed to meet the metabolic needs of freshwater organisms such as CaO and MgSO 4 . The purpose of this study was to determine the effect of CaO and MgSO 4 on growth and to determine the optimal dose of CaO and MgSO 4 . The results of this study are the highest survival rate at P3 with a yield of 70.33%, a specific growth rate of 3.33%, a specific length growth rate of 8.56%, an FCR of 1.66, a calcium content of 31,143 and a magnesium content of 28.92, temperature ranged from 27-30 C, pH 7.9 – 8.3, DO 4.1-6.8 mg/L, salinity 0 ppt, ammonia 0.1 mg/L, and alkalinity 118-140 Conclusions from this study namely the addition of minerals CaO and MgSO 4 can affect the growth of white shrimp and the best dose is 80 ppm CaO and 40 ppm MgSO 4 .
