Global assessment on extent and impacts of bottom trawling
Please join us on July 15th to hear about the findings of a global assessment recently completed by CEA Consulting, Sea Around Us, Duke University, and Virgil Group to map the extent of bottom trawling in nearshore waters globally, explore its impacts, and identify possible solutions to address its worst impacts.

Bottom trawling is a widespread fishing practice responsible for nearly a quarter to a third of global seafood production. Yet the practice has also been the target of many NGO campaigns for the ways in which it can unselectively destroy marine habitat and the frequent conflicts between industrial bottom trawlers and small-scale fishers in many parts of the world. A recent Nature paper (Sala et al., 2021) suggests that bottom trawling may resuspend the carbon in marine sediments, affecting the ocean’s ability to absorb carbon dioxide.

In an effort to understand the extent of this fishing method and its environmental and social impacts, CEA Consulting, with the support of Sea Around Us, Duke University, and the Virgil Group, conducted a global assessment of the catch caught by bottom trawling gears using Sea Around Us catch reconstruction data. We also conducted a literature review of environmental and social impacts, explored opportunities to limit the worst impacts of this fishing method with experts, and conducted a case study of West Africa. The research team looks forward to sharing these findings with you.
