| • Conducted within the AMBIO project, this work deals with coral reef fish communities and associated habitats, in the New Caledonian lagoons. It relies on remote unbaited underwater video observations, using the STAVIRO rotating technique. • The study takes place in the Pouebo area, part of the New Caledonian World Heritage site, and encompassing three no-take marine reserves enclosed within a Locally Managed Area (LMA). • The sampling design covers the entire area, and was stratified according to reef geomorphology and protection status. 86 stations were validated within 4 days. They were analyzed to characterize the habitat surrounding each station, and fish communities, based on a species list that includes fished species, emblematic species and... |

| Background. There is need for more information on behavioural rhythms of fishes in relation to their habitat use in few or not previously monitored areas, such as coralligenous habitats. Some studies have compiled inventories of observable fish species in this habitat, but no studies have been performed on the temporal patterning of fish behaviour, especially at the scale of the day. The presently reported study aims at providing knowledge on finescale fluctuations of abundances and behaviour of two fish species in coralligenous habitats throughout the diurnal period. Materials and methods. Fish fauna was filmed hourly, for several days, from dusk to dawn, with autonomous, programmable, and rotating video systems. Diurnal variations in abundances per... |
