Étude et protection des tortues marines grosse tête (Caretta caretta) sur les plages de la Roche Percée et de la baie des Tortues - Bourail : rappo...

Ce rapport rend compte de la campagne 2008/2009 d'étude et de protection de la ponte des tortues marines Caretta caretta, dites "grosses têtes" sur la plage de la Roche Percée et la baie des Tortues à Bourail. La campagne est menée par l'Associ...

Global analysis of gene expression dynamics within the marine microbial community during the VAHINE mesocosm experiment in the southwest Pacific

Microbial gene expression was followed for 23 days within a mesocosm (M1) isolating 50m(3) of seawater and in the surrounding waters in the Noumea lagoon, New Caledonia, in the southwest Pacific as part of the VAriability of vertical and tropHIc tran...

Akanthepsilonema oceanopolis sp. nov. (Nematoda: Epsilonematidae), a new free-living marine nematode from the Condor Seamount (North-East Atlantic Oce...

Epsilonematids are epifaunal nematodes characterized by an epsilon-shaped body and the presence of ambulatory setae, which are used in their locomotion. Nematodes belonging to this family were recently found in deep sea, especially in cold-water cora...

High rate algal pond treatment for water reuse in a marine fish recirculation system: Water purification and fish health

Regardless of the degree of closure of a recirculation system, effluents are produced and replacement water is needed, which limits the possibility of locating a seawater production system away from the shoreline. At the Palavas Ifremer station, in t...

Seasonal variation of riverine nutrient inputs in the northern Bay of Biscay (France), and patterns of marine phytoplankton response

Seasonal variations in nutrient inputs are described for the main rivers (Loire and Vilaine) flowing into the northern Bay of Biscay. The river plumes are high in N/P ratio in late winter and spring, but not in the inner plume during the summer. Cons...

Métiers, effort and catches of a Mediterranean small-scale coastal fishery: The case of the Côte Bleue Marine Park

The overexploitation of fishery resources has led to a major fisheries crisis. In this context, artisanal fisheries, and in particular small-scale coastal fisheries, appear as relevant alternatives for a sustainable use of coastal resources. Marine P...

Evaluation of floating cages as an experimental tool for marine shrimp culture studies under practical earthen pond conditions

The New Caledonia blue shrimp Litopenaeus stylirostris is commercially produced under semi-intensive rearing conditions. The size of the farming earthen ponds (5–10 ha) and the subsequent production constraints make it difficult to use them as exper...

Robust assessment of population trends in marine mammals applied to New Caledonian humpback whales [plus Supplementary material]

Estimating population trends for long-lived, migratory animals is challenging but essential for managing populations. Here we propose using a simple but potentially robust method, the direct estimation of population growth rate (PGR) from capture-rec...
