초록
Trawl fishing is a major concern worldwide, and there is considerable debate about its impact on marine ecosystems. In this study, we used the vessel monitoring system (VMS) data collected in the southwest Atlantic Ocean from 2016to 2019 to estimate the fishing effort and trawled area. Spatial distribution of trawl activities according to the latitudeand longitude and the hotspots where fishing was concentrated each year were identified. Trawling activities of theKorean vessels were mainly distributed between 40-52°S and 56-63°W. The species caught during the fishing periodcomprised five Cephalopoda, three Chondrichthyes, ten Osteichthyes, and other fish. The Argentine hake Merlucciushubbsi and Argentine shortfin squid Illex argentinus were the dominant species in the catch.
