Commercial fish assemblages on New Caledonian fringing reefs submitted to different levels of ground erosion ArchiMer
Letourneur, Y; Labrosse, Pierre; Kulbicki, M.
A comparative study was conducted in two zones of the Northern Province of New Caledonia, one located windward (east coast) and the other located leeward (west coast). In each zone, three major sectors were investigated: fringing reefs close to areas of important mining activities, fringing reefs close to areas of moderate mining activities, and fringing reefs close to areas free of mining activities. In addition, on the west coast, fringing reefs close to areas of high natural ground erosion were also studied. Only commercial fish species sensus late were censused on a total of 163 stations, concerning 165 fish species. Substrate characteristics were not different between zones and sectors. However, significant differences were observed for living...

Etat de santé des habitats et peuplements de poissons des atolls d’Entrecasteaux, zone inscrite au Patrimoine Mondial de l’Humanité et Parc naturel de la mer de Corail. Evaluation initiale par stations vidéo rotatives STAVIRO ArchiMer
Schohn, Thomas; Pelletier, Dominique; Carpentier, Liliane.
The AMBIO project conducted a comprehensive video-based baseline assessment of coral reef fish communities and associated habitats in the New Caledonian lagoons. Observation relies on remote unbaited underwater video, using the STAVIRO rotating technique (Pelletier et al. 2012).  This survey was conducted in 2015 in Entrecasteaux Reefs, both located within the Coral Sea Natural Park, and part of World Heritage site. 109 STAVIRO were validated in 9 days, covering the reefs and geomorphological units in the area. Images were analyzed to characterize the habitat surrounding each station, and fishes based on a list of 565 species (Pelletier et al. 2016).  28 indicators were computed and represented on maps (Sextant server). Indicators were analyzed using the...

Evaluation de l’état de santé des habitats et peuplements de poissons de la zone de Voh-Koné-Pouembout, Campagnes de stations vidéo rotatives STAVIRO 2007-2013 ArchiMer
Giraud-carrier, Charlotte; Pelletier, Dominique.
• 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...

Fish fauna of a mixed meadow composed by the seagrasses Cymodocea nodosa and Zostera noltii in the Western Mediterranean ArchiMer
Guidetti, Paolo; Bussotti, Simona.
The fish fauna of a shallow meadow composed by the seagrasses Cymodocea nodosa and Zostera noltii was studied in the Gulf of Olbia (NE Sardinia, Italy; Western Mediterranean). Visual censuses were conducted monthly from August 1995 to August 1996. Environmental variables for water temperature, salinity and seagrass shoot density were collected on each sampling occasion. A total of 23 fish species from eight families were recorded. Planktivorous species (Atherinids) numerically dominated the fish community, followed by necto-benthic fish, chiefly Labrids and Sparids. There was no discernible trend in total fish density. Species richness, diversity, evenness and density of necto-benthic species, instead, displayed a distinct seasonal pattern, higher Values...

Rapport de campagne vidéo «STAVIRO» - Parc Naturel Marin de Mayotte du 6 au 24 novembre 2017. ArchiMer
Giannasi, Paul; Gaboriau, Matthias.
La campagne STAVIRO Mayotte 2017 avait pour objectif d’acquérir les données afin de dresser un état des lieux des peuplements ichtyologiques d’intérêt commercial sur l’ensemble des récifs de Mayotte à l’aide du protocole STAVIRO. Elle a permis de confirmer la faisabilité du déploiement du protocole STAVIRO sur les récifs de Mayotte, et de valider le dimensionnement d’une campagne couvrant l’ensemble du complexe récifolagonnaire de Mayotte et du banc de l’Iris. Au total, 276 stations ont été posées pour 203 stations considérées comme exploitables (bonnes ou moyennes). L’implication de nouveaux partenaires et prestataires dans cette campagne (RNN M’Bouzi, opérateurs touristiques) permet de faire connaître et de familiariser les acteurs avec les techniques...

Utilisation de la technique vidéo STAVIRO pour l’observation et le suivi des ressources et des écosystèmes récifo-lagonaires de Mayotte. Etude pilote et recommandations pour les suivis futurs ArchiMer
Roman, William; Pelletier, Dominique.
• 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...
