The study was conducted from September 2014 to February 2015 through survey of 90 small scale white leg shrimp farmers (HH), 12 cooperatives (Co) 12 Farms (F) and 12 companies (Com) by using questionnaire. The results indicated that the total cultured area (ha/HH) and cultured ponds (ponds/HH) of NH were respectively 4.6 and 4.9 lower than Co (32.4; 30.3), F (15.1; 13.1) and Com (92.9; 83.7). Stocking densities, survival rate, cultured periods and harvested size of shrimp were highest in Com, followed by F, Co, HH, respectively shrimp yield 13.9 respectively; 10.6; 10.9 and 8.37 tons /ha/crop. The lowest production costs of F and highest in Comwere67.5 to 73.9 VND/kg, respectively. The profits (Mill/ha/crop) of all cultured forms were rather high, HH (596), Co (692), F (696) and Com (1,038) respectively. Benefit per cost was ranged at 1.0; 0.85; 1.03 and 1.04 times respectively. Profitability ratio in this research was very high, except for HH (unprofitable 6% of HH). Biosecurity level and staff capacity building activities of Com form was more considered than the other forms.
