Purpose : To understand mechanisms and controlling factors of coral bleaching and coral disease in coral reefs in the Mauritius, To know temporal and spatial distributions of fundamental chemical and biological parameters in coral reefs in the Mauritius. Results : Primary production and N2 fixation indicated that the contribution of coral rubbles and cyanobacteria mats maybe very important for the reefs. Evaluation of benthic community was usefull to understand the organisms diversity in the reefs. Corals health condition is good, without showing any bleaching pattern and almost no diseases were observed. And also coexsistence between seagrass and coral are important conditions for keeping health coral in the Mauritius. We concluded that actual condition of reef is quite healthy despite the strong human activities(fisheries and turism) impacting this reef, and this is maybe due to the good water exchange in the reef.
