Fish fences are used in tropical coastal regions to capture fish and funnel them into holding structures. The fences damage ecosystems and remove barriers to overfishing, according to a study published yesterday (May 21) in Nature Communications. The authors report a 15-year case study of the ecological and socioeconomic effects of fish fences in South America, West Africa, East Africa, the Persian Gulf, the Indo-Pacific, and Pacific Islands.
