Les sols des fonds de bassins et leur gestion durant les assecs. Etat des connaissances

Shrimp culture in New Caledonia has developed according to the "intensified" semi-intensive model which uses ponds that stretch over several hectares. Local shrimp farms are for the most part installed in "tannes", barren, highly saline areas of the ...

Contrat de Plan Etat Région Poitou-Charentes 1994-1998. Convention 95 RPC R 62 - Programme Pathologie - Rapport Scientifique année 1995

Le but de ce programme pathologie est de rechercher et d'étudier les agents pathogènes connus et inconnus chez les mollusques bivalves marins, plus particulièrement chez l'huître creuse, Crassostrea gigas, afin d'identifier d'éventuels agents ca...

The major outer membrane protein OmpU of Vibrio splendidus contributes to host antimicrobial peptide resistance and is required for virulence in the o...

Vibrio splendidus, strain LGP32, is an oyster pathogen associated with the summer mortalities affecting the production of Crassostrea gigas oysters worldwide. Vibrio splendidus LGP32 was shown to resist to up to 10 mu M Cg-Def defensin and Cg-BPI bac...

Comparative genomics of pathogenic lineages of Vibrio nigripulchritudo identifies virulence-associated traits

Vibrio nigripulchritudo is an emerging pathogen of farmed shrimp in New Caledonia and other regions in the Indo-Pacific. The molecular determinants of V. nigripulchritudo pathogenicity are unknown; however, molecular epidemiological studies have sugg...

Characterization of molecular processes involved in the pearl formation in Pinctada margaritifera for a sustainable development of pearl farming indus...

Tahiti’s pearl farming industry plays a major socio-economic role in French Polynesia. In an increasingly competitive market where the production of high quality pearls becomes essential, research can help secure and ensure sustainable production. ...

Is it possible to raise, offspring of the 25th generation of Litopenaeus vannamei (Boone) and 18th generation Litopenaeus stylirostris (Stimpson) in c...

Peneid shrimp are commonly reared in clear-water aquaria or tanks for short-term studies of 4-6 weeks during controlled experiments, such as nutrition studies to estimate dietary nutrient requirements. Recently, in line with the genetic program at Ce...

Phytoplankton community structure in the VAHINE mesocosm experiment

The VAHINE mesocosm experiment was designed to trigger a diazotroph bloom and to follow the subsequent transfer of diazotroph-derived nitrogen (DDN) in the rest of the food web. Three mesocosms (50m(3)) located inside the Noumea lagoon (New Caledonia...

Atelier marin, vers un suivi optimal des lagons et récifsIndicateur de pression de pêche en Nouvelle-Calédonie

Document qui donne de l'information sur les indicateurs de pression et d'impact de la pêche. les méthodes de suivi sont également abordées (pêche professionnelle et non professionnelle).

Monthly variability of self-recruitment for a coral reef damselfish

Understanding the dynamics of marine populations is critical to managing marine systems effectively and requires information on patterns of population dispersal and connectivity that are still poorly known. We used transgenerational marking to study ...

Introduction to the project VAHINE : VAriability of vertical and tropHlc transfer of diazotroph derived N in the south wEst Pacific

On the global scale, N-2 fixation provides the major external source of reactive nitrogen to the surface ocean, surpassing atmospheric and riverine inputs, and sustains similar to 50 % of new primary production in oligotrophic environments. The main ...
