Abstract
Beach seine fishing ranks among the most destructive in shallow coastal ecosystems worldwide, resulting in overfishing, habitat destruction, and biodiversity loss. Despite regulatory measures, illegal fishing continues across the Western Indian Ocean (WIO). This review gathers insights on beach seine fishing in the region from scientific papers and grey literature published over 30 years, from 1994 to 2024. We examine the historical evolution and document reported evidence on the ecological effects, management responses, socioeconomic considerations, and governance challenges associated with the fishery. The introduction of beach seine fishing in the region dates back to the 1650 s in South Africa and expanded to the entire region, with the most recent introduction occurring in Madagascar in the 1960s. Studies reporting catch characteristics, such as yield, species composition, and size distribution, were numerous, representing 81 % of the publications. However, quantitative assessments of broader ecological and socio-economic impacts were limited. Diverse management measures implemented, including complete bans (in Kenya, Tanzania and Madagascar), gear-based spatial and seasonal closures (in Mauritius, Mozambique, and South Africa), and technical restrictions on gear dimensions and use (in Mozambique, Mauritius, South Africa, and the Seychelles). Fishing gear exchange programmes have had varying levels of success, but remain the most promising. Drawing on experiences and lessons from the region and beyond, we outline a practical roadmap of actions implemented to phase out destructive fishing practices effectively. We advocate for long-term, holistic and multifaceted actions that foster community-led transitions while balancing ecological sustainability with socio-economic resilience.
期刊介绍:
Marine Policy is the leading journal of ocean policy studies. It offers researchers, analysts and policy makers a unique combination of analyses in the principal social science disciplines relevant to the formulation of marine policy. Major articles are contributed by specialists in marine affairs, including marine economists and marine resource managers, political scientists, marine scientists, international lawyers, geographers and anthropologists. Drawing on their expertise and research, the journal covers: international, regional and national marine policies; institutional arrangements for the management and regulation of marine activities, including fisheries and shipping; conflict resolution; marine pollution and environment; conservation and use of marine resources. Regular features of Marine Policy include research reports, conference reports and reports on current developments to keep readers up-to-date with the latest developments and research in ocean affairs.
