The study on the fishing activities of trawlers and gill nets was conducted from May to October 2018 in Kien Giang province. The results showed that the trawlers and gill nets had highest number of fishing boats and yields. Trawlers and gill nets have been operated whole year round. The main fishing season of trawlers was from October to coming April and from April to August for the gill nets. The fishing capacity of trawling boats was (47.8±24.6 HP) which was much larger than that of gill net boats (26.6±11.4 HP). The fishing yield and ratio of trash fish in the final product of trawlers were 39.4±15.9 tons/year and 22.83%, respectively and they were also higher than those of gill nets (26.6±11.4 tons/year; 16.8%). Profit of trawlers (338±114 million VND) was significantly higher than that of gill nets (143±73 million VND), however, rate of return of trawlers (0.66 times) was lower than that of gill nets (0.73 times). For the sustainable development of trawlers and gill nets, the development and management of fisheries resources should be promoted, and training fishermen to use appropriated fishing equipment to increase their fishing efficiency.
