How can science contribute to an ecosystem approach to pelagic, demersal and rock lobster fisheries in South Africa?

Abstract

South Africa is committed to moving towards an Ecosystem Approach to Fisheries (EAF) and has laid the foundations for this using a three-pronged approach: through a project (EAF Feasibility Study) under the Benguela Current Large Marine Ecosystem Programme; through a dedicated scientific working group established by the Marine and Coastal Management branch of South Africa's Department of Environmental Affairs and Tourism; and through collaborative scientific and modelling studies within the joint French-South African ‘Upwelling Ecosystems' Programme. This contribution provides an overview of the progress made towards developing an EAF in South Africa, both on the scientific front in terms of improved understanding of the functioning of the Benguela ecosystem and the ways in which its ecosystem components interact, and regarding the practical ways being explored to enable scientific advice to feed in to South African fisheries management while taking into account broad stakeholder concerns. The paper focusses particularly on the role played by scientific contributions (research and monitoring) to address these ecosystem issues in three important South African fisheries — pelagic, demersal and rock lobster — so that the appropriate management measures can be put into place. Socio-economic concerns are included for the rock lobster fishery.
