Data were collected through interviewing 60 vessels in Soc Trang and Bac Lieu provinces. The results showed that the average fishing production of the trawl net was 643 kg/trip and 18.9 tons/year with the time for each trip was about 4 days. The total cost for trawl net was 316 million VND/year and income was 608 million VND/year. The average technical efficiency of trawling was 86.3%. Captain-related factors such as experience, education, and age
vessel age, and production capital have an impact on the technical efficiency of the trawl net. To improve the technical efficiency of the trawl net industry, it is necessary to focus on training the captains, upgrading and exchanging large ships, and linking the market channels for the consumption of caught fishery products.
