Vannamei shrimp is an aquaculture product that is very popular because it has quite high selling power. Efforts to increase production are often carried out either by extensification or intensification. The Aquaculture Production Business Service Center in Karawang is trying to develop superintensive vaname shrimp farming technology with an indoor system. Rearing is carried out in fiber tanks with a volume of 1,500 ltr and the initial number of shrimp is 650 (A), 520 (B), and 400 (C). The initial seeds used have an initial weight of + 10.54 gr. Shrimp rearing was carried out for 28 days using a recirculation system and the parameters observed were the weight and survival of the shrimp as well as testing water quality as supporting parameters. The highest survival result was tank C (85%), then tank B (80%) and the lowest was tank C (78%). The high density in tank A caused high mortality at the beginning of rearing. The results of the final weight of the shrimp were not much different, namely 15.91 gr (A), 15.04 gr (B) and 15.04 gr (C). The ammonia concentration increased in the third week but returned to normal in the fourth week. The range of ammonia for each tank was 0.008-0.05 mg/L (A), 0.005-0.059 mg/L (B) and 0.002-0.041 mg/L ( C). This activity is a preliminary test for development on a larger scale in the following year.
