Resumo: | • Conducted within the AMBIO project, this work deals with coral reef fish communities and associated habitats, in the New Caledonian lagoons. It aims at assessing the status and trends of habitats and mobile macrofauna in the Voh-Kone-Pouembout lagoon, in the light of demographic and industrial developments and accounting for the existing customary reserve of Oundjo. • It relies on 280 stations collected in 2007 and 2013 using the remote unbaited underwater video STAVIRO rotating technique, which were analysed to characterize habitat, fish assemblages, turtles and sea snakes, from a list of 490 species (AMBIO/A/1). • 143 species (including one turtle species and one sea snake species), belonging to 23 families were observed. The most frequent and abundant families were surgeonfish and parrotfish, then goatfish, butterflyfish and emperors. Groupers and rabbitfish were rarely observed.  • 27 indicators were computed, mapped (maps available on a Sextant server), and analysed using the PAMPA computing tool. Outcomes were organized in a dashboard for each management objective (biodiversity conservation and fisheries management). • Coral status is rather good and stable, and shows no impact from anthropogenic pressures, even close to the plant and shipping channel. • Frequency of sharks, rays and humphead wrasses clearly dropped between 2007 and 2013. Turtles were rarely observed in both years.  • Fish community is moderately diversified, particularly in the Living Coral habitat. Herviores dominate species assemblage and piscivores are not abundant. • The abundance of several fished species distinctly declined between 2007 and 2013, but trends differed according to areas.
