| - The AMBIO project conducted a comprehensive video-based baseline assessment of coral reef fish communities and associated habitats in the New Caledonian lagoons. The survey relies on remote unbaited underwater video observations, using the STAVIRO rotating technique. - The study pertains to the reefs of Astrolabe, Pétrie and Walpole Island, located within the Coral Sea Natural Park. The survey conducted in 2014 covers the entire area, and the sampling design was stratified according to reef type. 95 stations were validated. They were analyzed to characterize the habitat surrounding each station, and fish communities, based on a list of 565 fish species (cf. AMBIO/A/1). - 28 indicators were computed and mapped (maps available on a Sextant server).... |

| - The AMBIO project conducted a comprehensive video-based baseline assessment of coral reef fish communities and associated habitats in the New Caledonian lagoons. The surveys rely on remote unbaited underwater video observations, using the STAVIRO rotating technique. Chesterfield and Bellona remote reefs and atolls are located in the Coral Sea Marine Park, northwest of New Caledonia. -This 2013 survey is the first scientific survey covering the entire area, with a sampling design stratified according to reef type. 203 stations were validated within 10 days. They were analyzed to characterize the habitat surrounding each station, and fish communities, based on a list of 565 fish species (cf. AMBIO/A/1). - 34 indicators were computed and mapped (maps... |

| • 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... |

| Les diagnostics des peuplements de poisson d’intérêt halieutique et des principaux stocks mettent en évidence des états contrastés à Mayotte en 2017. A l’échelle des peuplements, toutes espèces confondues, aucun signe patent d’un état non satisfaisant lié à la pression de pêche exercée n’a été observé. Cette situation s’explique en grande partie par les familles les plus diversifiées et les plus abondantes, souvent herbivores, tels que les poissons chirurgiens et les perroquets, dont l’état est jugé satisfaisant. En revanche, l’état des quatre principales familles de grands carnivores (les mérous, les vivaneaux, les capitaines et les carangues) est qualifié de non satisfaisant. La raréfaction des grandes espèces, voire la perte de diversité dans les... |

| • In order to assess the sustainability of fish resources in the Natural Marine Park of Mayotte (Western Indian Ocean), indicators and monitoring protocols must be determined. • This study relied on the underwater video technique STAVIRO for assessing fish communities and resources. A pilot survey was conducted in Nov. 2014 in the south-east quarter of the Mayotte lagoon, an area encompassing the marine reserves of Longogori, M’Bouzi and the Saziley Marine Park. Out of 115 stations collected, 104 were analysed for habitat and fish, based on a list of 527 species with fishing, ecological, or emblematic interest (cf. AMBIO/A/1). • 43 indicators were computed, analysed, and for some mapped. The PAMPA computing tool was used in this purpose. • 130 fish species... |
