This project focuses on three main points, which are 1) a habitat map of the three banks and an assessment of the live coral coverage as a proxy of the Geyser bank's health, 2) a description of fish assemblages and a functional analysis relative to habitat type and time and 3) an estimate of the abundance index in structure size of the main exploited stocks. Overall, 42 habitats over 268 km² were mapped on the Geyser bank with 534 field verifications. On the Zélée bank, 24 habitats were mapped over 183 km² with 204 field verifications. Finally, 36 habitats were characterized on the 235 km² of the Iris bank with 98 field verifications. For each bank, two maps were produced, 1) one characterizing low typology levels (N4) describi...

This tetraodontid fish has been reported from the western Indian Ocean, the Red Sea, and the Mediterranean. In this report, we confirm its presence in Saint-Paul Bay in Réunion and this new observation completes the ichthyological inventory of Réunion Island.

Deux spécimens de cette espèce ont été photographiés récemment sur des habitats artificiels lors de suivis scientifiques en plongée sous-marine. La présente étude, fondée sur des données mor-phologiques et morphométriques, valide l'identification de ces spécimens comme P. bicolor et constitue ainsi le signalement le plus occidental de l'espèce dans l'océan indien. Dans un contexte général de dégradation des habitats récifaux et d'accès difficile à certains habitats naturels non récifaux (e.g. profondeur, surface impor-tante, éloignement d'un port), l'exemple de P. bicolor présenté dans cette étud...

Major bleaching was encountered; nearly 80 % of the corals were bleached or dead (covered with thin algal overgrowth) on fringing reefs along the north coast, and 50 % and 35 % of the corals were bleached or dead at two sites on the east coast. The observations revealed spatial and temporal heterogeneity in the extent of the bleaching and mortality. The genera that appeared most susceptible to bleaching were Pocillopora and tabular Acropora, while Porites seemed to have suffered the least. Observations on the bleached genera were consistent with those made during the 1997-1998 bleaching event.
