RESUMO:

Recreational diving is a touristic activity fastest growing in the world, generating employment, income and contributing to the visibility of the importance of the conservation of the reef environments. Despite the socioeconomic advantages, when performed without control, recreational diving can cause negative impacts to the reef ecosystem. Several studies on coral reefs in the world have characterized these impacts by proposing management strategies and biological indicators for monitoring. The peculiarities of Brazilian reefs, with low coral cover and high seaweed and sponge cover, make it necessary to identify and define proper management strategies for this type of use. The present study aims to evaluate the impact of recreational diving causes in a Brazilian Marine Protected Area (MPA). The first chapter presents the survey of the main tourist destinations of recreational diving in Brazil, evidencing their similarities and the current state of research in which they are, regarding the impacts of recreational diving. The results indicate the growth of recreational diving in Brazil and its potential as a promoter of the conservation of reef environments. In the second chapter, it was characterized the behavior of recreational divers in an MPA in the brazilian northeast, quantifying the frequency of touches on the reef substrate related to the profile of the diver and characteristics of the type of diving performed. The average frequency of touches (FT) observed was significantly lower in the studied reef when compared to other studies on coral reefs in the Caribbean, Mediterranean and Australia. The variables that influenced the FT were: type of diving (scuba > snorkel), sex (men > women) and in the age group (above 50 years, higher than in the other age groups). The discussion in this chapter approaches how the physical characteristics of the place of study may have influenced the reduction of FT, as well as the posture of tourism professionals. The third chapter is under construction and deals with the impacts of recreational diving on the ichthyofauna and the benthic reef community, proposing appropriate indicators to the characteristics of Brazilian reefs. In this chapter, it is possible to observe changes in the richness, composition, biomass and trophic classes of fish, and analyze changes in substrate cover, biologic vulnerability, invertebrates’ megafauna and coral health in high and low use areas over two years. The fourth and final chapter approaches with the use of alternative methodologies in an Environmental Education (EE) project aimed at its effectiveness, focusing on the impacts that tourism promotes. The results indicate that the combination of scientific knowledge, local knowledge, use of media and visits to non-formal environment are fundamental to the effectiveness of an EE project. This thesis presents pioneers data on the impacts that recreational diving generates in Brazilian reef environments, effectively contributing to the management and development of sustainable tourism in marine protected areas.
