A framework for mapping small-scale coastal fisheries using fishers' knowledge

Collecting spatial information on fisheries catch and effort is essential to understanding the spatial processes of exploited population dynamics and to manage heterogeneously distributed resources and uses. The use of fishers' knowledge through geog...

Checklist of the fishes of New Caledonia, and their distribution in the Southwest Pacific Ocean (Pisces)

A checklist of the fishes of New Caledonia is presented. A total of 2328 species in 246 families have been recorded from the region. Eight of these species are not native, but have been introduced. Five fish families are represented only by introduce...

Remote High-Definition Rotating Video Enables Fast Spatial Survey of Marine Underwater Macrofauna and Habitats

Observing spatial and temporal variations of marine biodiversity from non-destructive techniques is central for understanding ecosystem resilience, and for monitoring and assessing conservation strategies, e.g. Marine Protected Areas. Observations ar...

Reconstructing individual food and growth histories from biogenic carbonates

Environmental conditions experienced by aquatic organisms are archived in biogenic carbonates such as fish otoliths, bivalve shells and coral skeletons. These calcified structures present an accretionary growth and variations in optical properties - ...

Assessing the impact of removing reserve status on the Abore Reef fish assemblage in New Caledonia

We propose a statistical approach based on multivariate analysis and general linear models to test the consequences of removal of reserve status from the Abore Reef fish assemblage of the Abore Reef reserve, New Caledonia. Consequences on fish densit...

Metabolomic variability of four macroalgal species of the genus Lobophora using diverse approaches

Among comparative metabolomic studies used in marine sciences, only few of them are dedicated to macroalgae despite their ecological importance in marine ecosystems. Therefore, experimental data are needed to assess the scopes and limitations of diff...

Intermediate water flows in the western South Pacific : as revealed by individual Argo floats trajectories and a model re-analysis

Thanks to the autonomous Argo floats of the OUTPACE cruise (Oligotrophy to UlTra-oligotrophy PACific Experiment) and of the THOT (TaHitian Ocean Time series) project, some features of intermediate-flow dynamics, at around 1000 m depth, within the cen...

Thanks to the autonomous Argo floats of the OUTPACE cruise (Oligotrophy to UlTra-oligotrophy PACific Experiment) and of the THOT (TaHitian Ocean Time series) project, some features of intermediate-flow dynamics, at around 1000 m depth, within t...

Surveillance des milieux récepteurs - Rapport annuel 2020 - Milieu marin

La surveillance du milieu marin dans la zone d'influence globale du complexe de Vale Nouvelle-Calédonie (ci-après Vale NC) et les zones témoins associées est effectuée sur la base de quatre groupes d'indicateurs physico-chimiques et biologiques,...

Analyse écorégionale du milieu marin de la Nouvelle-Calédonie

WWF-France a souhaité développer un projet pour la protection des récifs et des lagons néocalédoniens. Cette plaquette présente l'atelier qui avait été mise en place permettre l'identification de 19 aires prioritaires pour la conservation du ...
