Abstract: Cage culture of Basa fish (Pangasius bocourti) in An Giang province was investigated through interview 55 households in Chau Doc city (20 households), Tan Chau (20 households) and An Phu districts (15 households). The collected information included general information of households, technical and financial variables in cage aquaculture. The results showed that each farming household had 3.36 cages with average volume of 623 m3/cage. The high stocking density of 151 fish/m3 leads to the high yield of 1,457 kg/10 m3/crop in this kind of cage culture. After a culture period of around 10 months, the fish reached commercial size of 940 g/fish. The survival rate was high, 89.1%, and FCR was 1.85. The initial investment for cage farming was very high, in average of 19.8 million VND/10 m3. Within one crop, the input cost was 33.3 million VND/10 m3 and gained profit was 10.75 million VND/10 m3 and the profit ratio was 0.32 times. The common challenges of Basa cage aquaculture were identified as polluted water, unstable farm-gate price and lacking investment capital.
