| - 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).... |

| A beam trawl survey of the Bay of Vilaine was conducted from 1981 to 1997. Changes in the commercial fish community were analyzed by comparing the characteristics at the year and decadal scales. The community structure and nursery function of the Bay were steady during the period. However, specific richness, assiduity and distribution indices demonstrated a reduction in the second decade. The global abundance fell from 105.8 ind.ha-1 to 31.3 ind.ha-1. This trend was less marked for the external more marine stratum, which exhibited the lowest densities. The results are discussed in terms of ecological meaning of such a community, compared with the overall demersal fish community. The reasons of the decrease are questioned regarding nursery habitat, local... |

| - 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... |

| Depuis son introduction en Bretagne, au début des années 70, peu d'études ont été consacrées à l'huître creuse Crassostrea gigas sur cette région, sauf lors de pollutions (Amoco Cadis) ou d'anomalies de croissance de la coquille. En l'absence de données récentes, des stations expérimentales "d'élevage" ont été mises en place sur 8 sites conchylicoles bretons. Un lot d'huîtres de "18 mois" est réparti en début d'année dans 96 poches, à raison de 6 poches par station et 2 stations par site. Des mesures de biométrie, de composition de la chair, d'lindex de qualité, de taux de survie, et de parasitisme sont réalisées après 7 mois d'élevage. Après étude des résultats variable par variable, une analyse descriptive par A.C.P. montre 6 groupes de sites ou stations... |
