Resumo: | This study deals with fish communities and associated habitats of New Caledonian remote coral reef ecosystems. It was conducted in June 2014 within the AMBIO project. It relies on remote unbaited underwater video observations, using the STAVIRO rotating technique.  The study takes place at Matthew and Hunter volcanic islands within the Coral Sea Natural Park which encompasses New Caledonia’s Exclusive Economic Zone. The sampling design covers the leeward coast of each island. 9 stations were validated within 2 days. Stations were analyzed to characterize the habitat surrounding each station, and fish communities, including fished species, emblematic species and functionally important species.  Species composition, abundances, trophic structure of communities as well as fisheries resources are described using the PAMPA computing tool. Corresponding maps are available on a Sextant server (sextant.ifremer.fr, AMBIO catalogue).  Coral reef development is more advanced at Hunter due to the absence of recent seismic activity, whereas at Matthew, the water is quite turbid, due to ongoing gaseous emissions (but only 2 valid stations at the latter island).  85 fish species and a turtle species were recorded. At Matthew, apex predators dominated observations, but the latter are scarce and located in the area covered by the sulfur plume. In Hunter, fish community is more diversified and more abundant with both apex predators and sedentary species usually encountered in coral reef ecosystems.  A large proportion of commercial species were observed at both islands (resp. 25% and 30% in Matthew and Hunter), but more fish resources were observed around Hunter.
