How Bottom Trawling Is Starving Coastal Communities Worldwide
Bottom trawling is reshaping coastal communities around the world. The practice now accounts for over a quarter of all marine fish caught globally. Yet its expansion is pushing local food supplies to the brink, leaving many without reliable access to affordable seafood. In Alaska's Yukon-Kuskokwim Delta, industrial trawling over the past two decades has slashed salmon and whitefish numbers by 40–60%. The decline has disrupted traditional Yup'ik fishing methods, cutting off a key food source for Indigenous families. Meanwhile, in southern Brazil, a 12-nautical-mile trawling ban has helped stabilise nearshore fish stocks, limiting local declines to just 10–20%.
The impact stretches further. In Goa, India, families face rising seafood prices as trawlers divert high-quality fish to global markets. Women in the Global South and Indigenous regions suffer most, losing income as small-scale fisheries collapse. Even when total fish catches remain steady, food insecurity grows when communities can no longer access affordable seafood. Beyond economic strain, trawling sparks conflict. Industrial vessels often replace artisanal fishers, damaging ecosystems and deepening inequality. Experts now urge policymakers to embed food security into fisheries management, ensuring coastal communities retain access to their traditional resources.
The contrast between Alaska's collapsing stocks and Brazil's recovery highlights the stakes of trawling policies. Without stricter controls, industrial fishing will continue to erode local food systems. For now, exclusion zones and targeted bans remain among the few proven ways to protect both fish populations and the people who depend on them.
