The growth in tourism in the Cape Verdean Sal Island has been a cause as well as a consequence of a number of investments (both by the State and the private entities) to create synergies for that sector, ensuring and promoting the island’s touristic attractiveness. Such increases in the number of visitors, allied with the island’s marine biodiversity - that make up much of its economic potential - have caused the growth of the diving industry, which has become one of the biggest attractions for tourists. In light of the scarcity of scientific studies on the impacts associated with this activity and means for diver engagement, the local diving operators have proposed the development of several tools.

An Underwater Species Identification Guide and four underwater routes were proposed for four popular scuba diving sites off Santa Maria Bay (Sal Island, Cape Verde): “Kwarcit”, “Sargo”, “Três Grutas” and “Tchuklassa”. To better understand how the diving industry could promote environmental education, conservation and enhance biodiversity awareness among divers, we also established the diver tourists’ profile using an online survey.

A total of 347 respondents, of which 85% have higher education, showed that 67% stay more than seven nights in Cape Verde. Moreover, natural reefs are the 1^st dive site to be visited, while artificial reefs preference increases after a second dive on the man-made reefs. The majority would recommend the use of the Underwater Species Identification Guide and the underwater routes.

The results showed that divers strongly embrace the use of new tools for better understanding of diving site biodiversity and that the diving industry can play an important role in the enhancement of biodiversity awareness.
