  The trial was conducted in earthen pond with average initial weight of 4.5 ± 0.4 mg/PLs of green tiger shrimp, to examine the effect of three stocking density and two water exchange rate on growth performances, production traits and feed composition. Eighteen earthen ponds (2200 m2) were stocked with either, 5, 15 and 25 PLs/m3, and received either 10 or 20% of water exchange rate. The results revealed that, mean final weight (g/PLs), gain in weight (g/PLs), gain in weight %, SGR (% /day), feed conversion ratio, protein productive value (PPV), protein efficiency ratio (PER), fat gain and energy utilization were significantly (p≤0.01) the best at the lowest stocking density. While, total production exhibited significantly the opposite trend. There significant differences (P≤0.05) were found between water exchange rate in term of mean final.. View More»
