The results showed that semi-intensive farming is mainly practiced, accounted for 53.3 percent, pond area ranged from 0.3 to 1.5ha with an average area of 0.58 +/- 0.01ha per pond, ponds were rectangular shape with the average depth of 1.43 +/- 0.015m (ranging from 0.6 to 1.8m), pond bottom with muddy sand accounted for 69.2 percent. Pond preparation after each culture crop was focused by farmers, especially in forms of semi-intensive and intensive farming. Profits gained was various among culture models, gradual increasing from improved extensive to intensive farming models. Profits gained in improved extensive, semi-intensive and intensive models of culture were 54.4, 212.8 and 267.2 million VND, respectively.
