【 摘 要 】

The objective is polyculture technology of red tilapia larasati fish and white shrimp with different combinations density. The material is saline red tilapia larasati 3.29 ± 0.018 g and white shrimp with initial weight 1.39 ± 0.025 g. Seeds are density of red tilapia larasati larvae 5 and 10 larvae / m2fish. And white shrimp 5 larvae / m2and 10 larvae / m2. An artificial feed used enzyme dose of 2.25 g / kg. The experimental using complete randomized design 4 treatments and 3 replications that is given seeds 5 larvae / m2larvae red tilapia larasati and given 5 larvae / m2white shrimp (A), 5 larvae / m2red tilapia) and 10 m2/ m2of white shrimp (B), 10 m2larvae and 5 m2white shrimp (C), 10 m2larvae and 10 m2white shrimp (D)). The data were growth of absolute weight, survival rate, FCR, and water quality data (temperature, salinity, pH, O2, NO2, NH3). Data were analyzed of variance (F test). The results showed significantly effect (P
