Litopenaeus vannamei is a new species to India; right now culture technology is not comparable with black tiger shrimp. Bearing all those in mind the present study was carefully carried out. In the present study an attempt has been made to culture the white leg shrimp, L. vannamei in two ponds each with 0.6 ha in Kodakaramulai, Sirkali taluk, Nagai District, Tamilnadu. The salinity of the two ponds was ranging between 22-30 ppt and DO values fluctuated between 4.0 mg/l and 5.0 mg/l in the morning and between 4.5 mg/l and 6.5 mg/l in the evening. Ammonia was recorded maximum 0.3ppm and minimum was 0.1ppm. During the culture after 50th DOC there was a poor growth observed in both ponds due to white gut and white fecal matter. Immediately feed probiotic (Bacillus sp) mix with the feed for three weeks and two meals per day. The problem was slowly rectified. The maximum Survival 85% in pond 2 and 82% survival was recorded in pond1. The present study confirm that, shrimp farming community need more awareness to use feed probiotic, proper water qualitymanagement and feed management is essential for the successful culture.
