مرده یا زنده: اهمیت فزاینده غواصی کوسه در منطقه میانه آتلانتیک

In the Mid-Atlantic Azores, the emergence of a seasonal ecotourism shark diving industry strongly contrasts with a North Atlantic shark fishery for regional, national and foreign fleets. Shark diving may provide an economic alternative to fishing, promoting an ecological and economical sustainable use of these animals, favouring their conservation. Understanding socio-economic aspects of this new Mid-Atlantic industry is the first step towards its sustainability and ultimately shark conservation. Data were collected by means of questionnaire designed to solicit information on shark divers’ knowledge, socio-economic status, expenditures and expectations, conducted between July and August 2014 on Pico and Faial Islands, to 144 divers. The majority of respondents were male (71%), between 25 and 40 years (41%), mainly from Germany, Holland and Austria, and 44% visited the Azores purposely to dive with sharks. On average, 2.6 sharks were seen per dive and 97% of respondents did not perceive any form of shark aggression or threat. The estimated generated income of shark diving in 2014 for the Azores amounts to 1,983.347€ (around US$2,244.890). Such an amount may easily increase following the current rates of expansion for (eco)tourism in the Azores and the infancy of the local shark diving activity. Finally, it is worth saying that nearly 70% of participants were willing to pay an extra amount until 60€ to ensure that shark diving remains an option and more than half (53%) would like to see that amount invested in conservation.
