Socio-economic aspects of the tiger shark diving industry within the Aliwal Shoal Marine Protected Area, South Africa

ML Dicken, SG Hosking

Abstract


Understanding socio-economic aspects of the tiger shark Galeocerdo  cuvier diving industry, including information on participant expectations, experiences and expenditure, is necessary for the effective management of the Aliwal Shoal Marine Protected Area on  the east coast of South Africa. Between January and December 2007, a total of 2 133 tiger shark dives was conducted by 1 065 divers (95% CI = 946–1 198). Data were collected by means of the administration of a semi-structured survey questionnaire to 197 (18.6%) dive participants. Respondents indicated that the direct value of tiger shark diving to the Aliwal Shoal region was R12 405 274 (95% CI = R10 777 324–14 228 541). A total of 1 000 Monte Carlo simulations was used to estimate confidence intervals. On a ranking from one (poor) to five (excellent), the average participant response to overall quality of dive and standard of dive operator was 4.6 and 4.7 respectively. The majority of divers (98.0%) observed a tiger shark, at an average of four per dive. Although tiger sharks approached to an average distance  of 1.6 m from divers, the majority (95.9%) felt safe and enjoyed the  experience. The majority of interviewees (88.5%) supported the use of chumming for a closer ‘tiger shark experience’.
