What to know about Study reveals that bottom trawling catches thousands of fish species, including those most at risk

A study published in Reviews in Fish Biology and Fisheries reveals that bottom trawling captures over 3,000 fish species, including many at risk of extinction. Researchers highlight the lack of data on species impacted by trawling and call for improved management practices to protect marine biodiversity. The study emphasizes the urgent need for governments to regulate trawling activities within national waters.
