Market access, population density, and socioeconomic development explain diversity and functional group biomass of coral reef fish assemblages

► Fishing pressure explains diversity and function of coral reef fishes. ► But markets, population density and socioeconomic development explain fishing. ► Market access strongly increases fishing, reducing key functional group biomass. ► Human population density increases fishing, affecting reef fish diversity. ► Socioeconomic development has weak positive and negative effects on fishes.
