Climate change significantly impacts marine fisheries by altering ocean temperature, changing fish migration patterns, and affecting the availability of prey species. Warmer waters can lead to shifts in species distribution, often pushing fisheries toward higher latitudes or deeper waters. Additionally, ocean acidification affects the health of coral reefs—vital habitats for many fish species. These changes can disrupt local economies that rely on fishing for livelihoods and food security, while also threatening the sustainability of various fish populations.
