Suivi environnemental du milieu marin (2010-2012) - Qualité physico-chimique des eaux (ST15 & ST16) et des sédiments - Synthèse mars, mai, août et...

Cette étude fait suite à une demande de définition de « l'Etat de référence » de la qualité physico- chimique et des niveaux de concentration des métaux dissous des eaux et des sédiments dans la zone sous influence portuaire. Ce pro...

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

Scientific and technical studies carried out under semi-intensive farming conditions, with large earthen ponds (Fig 1), to assess the effects of treatments on zootechnical results are highly complex due to the many logistical, economic and/or experim...

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...

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...

Further brominated bis- and tris- indole alkaloids from the deep water New Caledonian marine sponge Orina sp.
