Abstract

This contribution briefly recalls the declining status of global fisheries and marine ecosystems, with emphasis on the Central West Atlantic and the Caribbean. It then present a methodology for studying the potential effect of global warming on marine biodiversity and fisheries, whose results lead to the conclusion that fisheries catch potentials will shift toward higher latitudes, and lead to severe impacts in tropical waters, including the wider Caribbean. These finding highlight the need to rebuild fish population, particularly through marine protected areas, as high biomasses are needed both as basis for sustainable fisheries and to mitigate the effect of climate change.
