The present study is the report on the culture of L. vannamei in the brackish water shrimp farm in Bhimavaram, west Godavari district, Andhra Pradesh, India. The study was conducted in four culture ponds at different stocking densities. Crab fencing and bird netting was done before pumping water to prevent the autoentrants. The average pH reading for the AM was 7.9 to 8.8, while a pH of 8.2 to 9.1 was recorded in the PM. After 110th days of pond culture, the mean average weights of the shrimp at harvest were 21.2, 18.9, 19.6, and 17.5; survivals were 82, 92, 81, and 80 %; FCR was 1.4, 1.34, 1.38, and 1.35. The average production was 8750, 9813, 8138, and 8591 kg/ha for P1, P2, P5, and P6, respectively. Two way ANOVA was attempted between stocking density and Average body weight (ABW). The calculated p value was 0.0017. Its shows the relationship between stocking density and average body weight is highly significant. So ABW increases with less stocking density and vice versa. The present investigation it was concluded that L.vannamei culture is successful in brackish water environment and the growth is directly related to stocking density.
