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.
