A study on feed utilization, and the suitability of water quality and the estimation of vaname shrimp (Litopenaeus vannamei) growth and production of an intensive system was conducted in Pelabuan Ratu, West Java during Mei-Agustus. The research was aim at evaluating feeding practices, and suitability of its water quality obtained. This study was based on observations six ponds during one growout period (100 days) with causal design and ex post-facto method to obtain data on water quality and production. The result showed that degradation of water quality occurred not until the 40th day of cultivation, and progressively decreased up to the end of the growout period. The high level of feed utilization produced suitable water quality, and high shrimp growth rates, thus, yielding high shrimp biomass. Feed-shrimp biomass relationship could be expressed by the following quadratic regression: y = 0.00006x2 + 1.3506x + 7.3864 (R2 = 0.9801), from which the maximum shrimp biomass was reached at 7 593 kg on 11 255 kg feed, giving a feed conversion ratio of 1.48.
