- W2189338045 abstract "South Africa has a diverse marine environment, including coastal upwelling and subtropical waters. Over 550 fish species are directly impacted by fisheries. About 15 of these are well‐ managed, whereas the remainder have proved too expensive or too disaggregated to monitor and assess. Many fish species have declined drastically in range and abundance as a result of harvesting. Other pervasive threats are mining and alien species. Presently South Africa has twenty‐one MPAs and a few closed areas for fisheries, dating back to 1964. Nineteen percent of the coastline is covered by MPAs, and 9% is no‐take, but the fraction of the EEZ that is protected is only 0.41%. A systematic conservation assessment recognised gaps in protection on the west coast, along sandy beaches and offshore. MPAs have led to local recoveries in fish populations, as shown by abundance indices and size‐ structure. Fish community structure, reef invertebrate communities, and fish physiology have also responded to protection. Models have suggested that reef fisheries have responded positively to MPAs, but tests of this prediction have not been possible. Fish movements studies have suggested many likely mechanisms for protection and fishery enhancement. Support for coastal MPAs is strong, but it varies among user groups and fishing sectors. In contrast, the declaration of offshore MPAs has not found easy acceptance among industrial bodies. A comprehensive conservation planning exercise has recently earmarked certain offshore areas for protection, but the extent to which they will deliberately contribute to fisheries management is uncertain." @default.
