Probiotic Tiger Shrimp (Penaeus monodon) Farming at Different Stocking Density and its Cost Benefit Analysis

Abstract

Shrimp aquaculture production in much of the world is depressed by disease. So probiotics farming has tremendous scope for controlling various diseases. Determination of suitable stocking density of shrimp for probiotic farming is very necessary because of profit. In this present study different stocking densities ponds were cultured by using various probiotics and compared them with each other. Per Kg production cost were lower in 10 pcs/m2 compared with 5 pcs/m2 and 15 pcs/m2. FCR was low (1.3) in 5 pcs/m2 densities and high (1.6) in 15 pcs/m2 densities. Survival of 5 pcs/m2 densities shrimps were 70%, 10 pcs/m2 densities shrimps were 60% and in 15 pcs/m2 densities shrimps were 48%. By cost benefit analysis of this culture, it is easy to say which density culture is most profitable and suitable. This present study showed that 10 pcs/m2 densities were most profitable (159010 Tk, profit 63%), 15 pcs/m2 densities were not so profitable (124013 Tk, profit 37%) because of slow growth and 5 pcs/m2 densities were not so profit (68295 Tk, profit 40%) because of high production cost and low production. So we can easily conclude that 10 pcs/m2 cultures were most profitable in semi-intensive probiotic shrimp farming system.
