Abstract
The study conducted a survey of the products of 30 fishing sets of the trawler fishery from February to March, 2022 in the waters of Quang Binh province. This paper focuses on the estimation of the impact level of trawl fishery on fisheries resources of 18 important economic species groups and 12 targeted species. The results showed that the catch productivity decreased by about 10% in the last 3 years, the proportion of the commercial species groups decreased while the trash fish group increased (accounted for 64.7%); The group of economic species but immature caught accounted for a high proportion of the catch ranging between 63.3 and 91.1% with an average of 78.9% and the sublegal-sized individuals accounted for a high proportion of the catch, ranging between 71.8% and 92.1%; All aquatic economic species exceed the prescribed threshold on the percentage of juvenile fish that are allowed to be mixed in the catches.
