    The South African coastline stretches from the mouth of the Orange River in the northwest to Kosi Bay in the northeast, a distance of some 3000 km. It covers a wide range of habitats from kelp beds to mangrove forests and coral reefs. The Benguela ecosystem on the west coast is characterised by upwelling and extends from Cape Point northwards, constituting the Namaqua biogeographic province. The warm temperate Agulhas biogeographic province is found on the south coast from Cape Point to East London and the Natal biogeographic province along the sub-tropical east coast. Marine biodiversity in south Africa is particularly high as a result of this environmental variability. Commercial, recreational and subsistence fisheries are discussed, many of which are harvested sustainably because of conservation legislation instituted by management agencies. There is no room for complacency, however, as there has been a serious depletion in some instances. Demographic pressures on the estuarine and coastal environments are cause for concern as well as the popular misconception of the sea providing an endless supply of food and as a repository for unlimited waste

    A survey of the invertebrate subtidal and estuarine resources on the Transkei coast was undertaken in April 1993 by the Oceanographic Research Institute in association with the University of Transkei (UNITRA). This survey examined the stocks of abalone, rock lobsters, mud crabs, oysters, subtidal mussels, and sand and mud prawns. During the latter half of 1993, the Zoology Department of UNITRA examined shellfish resources in the intertidal zone along the coast. Information on past and current levels of utilisation of all resources was collated and, where possible, survey and biological data were combined to make preliminary assessments of the potential for sustainable utilisation
