    ENGLISH ABSTRACT: The aim of this study was to determine the scale of marine poaching in the Table Mountain National Park by analysing the amounts of South African abalone, West Coast rock lobster, and shellfish, finfish and bait species confiscated from fishers operating in the park’s marine protected area between 2000 and 2009. The research objectives were fourfold, namely to strengthen conceptual frameworks on illegal harvesting in protected areas; identify the quantities of the various species seized by park officials over the decadal period; cartographically plot the areas in which confiscations took place; and distinguish the different resource users and stakeholders operating in the park and examine the roles they play in resource exploitation. Data was collected from offence logbooks maintained by SANParks rangers and managers, and from records kept by Marine and Coastal Management and the South African Police Services. GIS outputs indicated seizure events over the spatial area of the park. Further data relating to the levels of poaching was sourced from illegal fishers operating in the park who discussed their operations candidly. The research findings indicate that poaching of both abalone and rock lobsters has increased significantly over time. Other marine species show lesser amounts of resources poached over the ten-year period. Spatial outcomes suggest that confiscations of abalone occur predominantly on the east coast of the park, while higher seizure events occur on the west coast for lobsters. Shellfish, finfish and bait species were confiscated in equal amounts from illegal fishers on both the east and west coasts. Future research recommended includes garnering further confiscations data from the police services and undertaking contemporary baseline assessments to discover the effects poaching has had on the resource base since the previous stock assessment in 2001. The challenge laid out for the custodians of the Table Mountain National Park marine protected area is to provide and protect cultural and environmental resources, without compromising biodiversity management, community associations and conservation strategies.
