ABSTRACT
Litopenaeus vannamei is a fast-growing aquaculture species in India; right now, culture technology is not comparable with black tiger shrimp. Keep in mind the present experimental study was carried out. In the present study has been made to farming of the white leg shrimp, L. vannamei in three ponds each with 0.6 ha in Nellore, Nellore District, Andhra Pradesh. The salinity of the two ponds was ranging between 15-20 ppt and DO values fluctuated between 4.0 mg/l and 6.0 mg/l in the morning and between 4.5 mg/l and 6.5 mg/l in the evening. Ammonia was recorded maximum 0.2ppm and minimum was 0.1ppm. During the culture after 55th DOC there was a poor growth observed in both ponds due to white gut and white faecal matter. Immediately after observing the disease condition taken the feed probiotic (Bacillus sps.) mix with the feed for three weeks and two meals per day. The problem was slowly rectified. The maximum Survival 88% in pond 2 and 85% survival was recorded in pond1. The present study confirms that, shrimp farmers need more awareness to use specific feed probiotic, best management practices like proper water quality management and feed management for the successful shrimp farming.
