Effect of Stocking Density on Growth Performance, Survival
and Economic Efficiency of Litopenaneus vannamei (Boone, 1931)
Cultured in Quang Nam Province
ABSTRACT
An experiment was carried out with two treatments corresponding to two stocking densities (200 and 400 postlarvae12/m2) with 4 replicates to determine the effect of stocking density on growth performance, survival and economic efficiency of intensive white leg shrimp farming in Quang Nam province The results showed that with density of 200 and 400 postlarvae12/m2 after 90 days of stocking, the final weight, yield, survival and profit were 13.04 and 10.9 g/each shrimp; 15.55 and 20.66 tons/ha/crop; 65.24 and 56.86%; 489.2 and 62.8 million VND/ha/crop Keywords: density, intensive, profit, survival, yield, white leg shrimp
