The authors’ initial global model of mangrove fisheries was built up front a detailed review of hundreds of studies from around the world, and informed by an expert panel. In terms of natural productivity, the most important areas are those with high input of freshwater and nutrients notably focused around estuaries, deltas and lagoons, particularly in the wet tropics. Fishing effort of course is uneven, but centered in areas where high populations live close to mangroves, or where smaller fishing populations may nonetheless have access to urban markets.
