• A mangrove ecosystem encompasses two environments, a larger flooding area with a characteristic wetland forest, and a less flooded area, more saline with little or no vegetation cover, known as hypersaline tidal flats ( apicuns ). Cardisoma guanhumi is a non-abundant, semi-terrestrial crab that lives mainly in apicuns . This environment is smaller and less impacted in comparison with mangrove forests. This study aims to investigate the spatial relation between apicuns and mangroves as a habitat extent of C. guanhumi along the Brazilian coast and its implications on fishery management and conservation status of this species in Brazil. The study was based on apicum and mangrove extent maps of the Brazilian coast. The maps were analyzed based on variations in latitude and environmental and socio-political aspects. Along the Brazilian coast, we found 11,721 km 2 of mangroves and 402 km 2 of apicuns . The habitat of C. guanhumi varied greatly with latitude and is interdependent of mangrove ecosystem. This latitudinal gradient and the apicum -mangrove relation suggest the need for different management strategies of this fishery species along the Brazilian coast. Such strategies should be used to maintain the population of C. guanhumi in sizes that guarantee its conservation and recovery aiming to remove this species from the category of vulnerable in the Brazilian red list of threatened species.
