Bottom trawling is widely used to harvest fish and other marine life by dragging weighted nets along the seafloor. Multiple reports describe the process as indiscriminate: nets sweep up most organisms they encounter, and the gear can destroy or disturb seafloor habitats in the areas where it operates. One outlet notes that bottom trawlers account for about one-quarter of the world’s fisheries catches by weight, raising broader concerns about ecological impacts and potential economic and social effects. Both sources emphasize that basic information about the scale of what is being caught—such as how many fish species are taken and which species are most affected—remains an important unanswered question. The coverage frames bottom trawling as a practice that can remove large amounts of marine life while also altering the seafloor environment, but it highlights a need for clearer data on species composition and catch outcomes to better assess impacts.
