Effect of density on growth and production of Litopenaeus vannamei of brackish water culture in rainy season with artificial diet, India

Danya Babu Ravuru and Jagadish Naik Mude

The Pacific white shrimp Litopenaeus vannamei (Boone, 1931) is an Ecological important tropical and euryhaline species. The culture of L. vannamei was taken from three ponds each one 0.6 ha for the study. Semi Intensive culture system was selected in Chinaganjam village (Prakasam District). The species L.vannamei (post larvae) stocking densities taken from three samples each one (3, 60,000) 60 species/m2 and survival were 84, 86 and 88%. In rainy seasons in month of June to September, the water quality parameters were measured fortnightly in a month at 7a.m. The production was 6248, 6633 and 6945kg / 104, 110 and 112 days and FCR was 1.64, 1.51 and 1.71 for P1, P2 and P3, respectively. The artificial diet was provided 4times/day given made by Manamei feed pellets (Protein 35 and 34%). The final growth was 21.2, 22.20 and 22.70g/104,110 and 112 days, respectively.
