Effect Of Probiotics On Growth, Survival And Yield Of Penaeus vannamei (Boone, 1931) In Culture Ponds At Susaram Village, Srikakulam District, Andhra Pradesh

Abstract

The main objective of this study was to evaluate the growth, survival rate and yield of Penaeus vannamei during 120 days of culture period in two experimental ponds with same stocking densities i.e.1,25,000 PL/ acre  pond. Out of two ponds, one is probiotic treated pond and other is control pond. The Blanca, CP. Pvt. Ltd., shrimp feed was given as supplementary feed in both experimental ponds. The Probiotic, SUPER-PS, CP. Pvt. Ltd. was applied in treatment pond. The experiment was done in Winter Season at Susaram village, Srikakulam District, Andhra Pradesh. In the present study Penaeus vannamei yield observed after completion of the 120 days experimental period was1562.2 kg/acre in control pond, whereas the highest yield 2246.4 kg/acre was reported in treatment pond. The survival rate 60% and 72% was noticed in control and treatment ponds respectively. The Specific Growth Rate observed in control pond was 4.535% , whereas in Treatment pond it was 4.654%. The lowest Average Daily Growth 0.17g/day was notice in control pond, whereas the highest growth 0.20g/day was noticed in treatment pond. The lowest FCR 1:1.25 was reported in treatment pond and highest FCR 1:2.13was noticed in control pond.
