| Abstract |
Climate change has significantly impacted marine ecosystems, including the migration patterns of pelagic fish in the tropics. This study uses a systematic literature review (SLR) approach to examine the economic impact of changes in the spatial distribution of pelagic fish triggered by increased ocean temperatures, changes in currents, and water stratification. The review of 38 selected studies out of 194 screened indicates that changes in fish migration have a significant impact on the capture fisheries sector, particularly through reduced catches, rising operational costs, and growing uncertainty for fishers. In addition, developing countries in the tropics face greater economic risks due to limited adaptation and high dependence on fisheries as a source of livelihood and foreign exchange. This research highlights the importance of ecosystem-based adaptive policies, investment in climate-responsive fisheries information systems, and regional cooperation in managing transboundary fish stocks sustainably. The findings support the establishment of digital skills training programs, community-based adaptation, and support for technology-based maritime entrepreneurs are strategic steps to build coastal communities that are resilient to climate change. |
