SUMMARY:

Coral reefs are ecosystems that have high biomass and high productivity, providing support for the growth and development of marine organisms. In this way they have high ecological importance providing numerous services to the marine ecosystem. In recent years, major changes are taking place in the structure and ecological processes of coral reefs as a result of the increase in anthropic disturbances on a global and local scale, in the short or long term, characterizing a “crisis of functionality” in reefs, increasing rates of coral mortality and impairing the resilience potential of this ecosystem, giving rise to new reef systems with low rates of coral cover. The use of biota and information from ecological systems as quality indicators to understand the ecological status of reefs is growing. The present study aimed to evaluate the health of the coral community and the quality of reef areas through ecological and biochemical indicators. The efficiency of using these indicators as a monitoring tool and an effective instrument for decision-making in the management of these areas was evidenced in this dissertation over two chapters. In the first, the results suggest that the management of use through spatial zoning and compliance with regulations in these areas can contribute to the resilience of coral reefs, maintenance and efficiency of ecosystem, socioeconomic and cultural services in the APACC, also indicating that the creation of this zoning was an assertive decision that must be maintained and expanded. In the second chapter, it is suggested that the activities of antioxidant enzymes differ due to the seasonal effect, depending on the increase in river discharge and the concentration of some inorganic nutrients, and that even though they are exclusion areas, these zones are subject to impact and the corals are under stress. Attention is drawn to a more detailed monitoring of these areas to assist in the management and ensure efficiency in the conservation and maintenance of reef ecosystems
