French Marine Economic Data 2013

The maritime economy includes the activities linked to the sea, namely: - Marine resource extraction: living resources and marine minerals, - Exploitation of marine space and of physical properties of marine waters (energy plants - using marine wat...

Etude des tris précoces en élevage de crevettes P. stylirostris dans un objectif de sélection génétique. Février à Juillet 2000.

Schemes optimisation for genetic improvement for growth of Penaeus stylirostris requires the development of technologies for grading shrimps easily. This work shows that bar and mesh graders are very suitable for early selection at post-larval stages...

Experimental evaluation of co-culture of juvenile sea cucumbers, Holothuria scabra (Jaeger), with juvenile blue shrimp, Litopenaeus stylirostris (Stim...

The co-culture of juvenile sea cucumber Holothuria scabra (Jaeger), or 'sandfish', with juvenile blue shrimp Litopenaeus stylirostris (Stimpson) was tested by growing groups in co-culture and monoculture for 3 weeks in tanks with enriched sand substr...

Ongoing geographical spread of Tomato yellow leaf curl virus

Tomato yellow leaf curl virus (TYLCV) seriously impacts tomato production throughout tropical and sub-tropical regions of the world. It has a broad geographical distribution and continues to spread to new regions in the Indian and Pacific Oceans incl...

Stratégies de lutte contre la tique du bétail en Nouvelle-Calédonie. Synthèse des connaissances

La tique du bétail introduite sur le territoire en provenance d'Australie lors de la Seconde Guerre mondiale, constitue une des principales contraintes de l'élevage bovin. Elle génère des pertes économiques qui peuvent être insupportables pour ...

Vallitalea pronyensis sp nova, isolated from a marine alkaline hydrothermal chimney

A novel thermotolerant, anaerobic, Gram-stain-positive, spore-forming bacterium was isolated from a hydrothermal chimney in Prony Bay, New Caledonia. This strain, designated FatNl3(T), grew at 15-55 degrees C (optimum 30 degrees C) and at pH 5.8-8.9 ...

Late Holocene sea-level change and reef-island evolution in New Caledonia

In New Caledonia, numerous rays are distributed on platform reefs in the southwest lagoon behind the barrier reef. At Mba Island, a vegetated sand cay in this area, we examined Holocene sea-level change, and reef development and evolution. The late H...

Colonization and release processes of viruses and prokaryotes on artificial marine macroaggregates

Marine organic aggregates are sites of high of viral accumulation; however, still little is known about their colonization processes and interactions with their local bacterial hosts. By taking advantage of a novel approach (paramagnetic functionaliz...

Segregation in diet between Black Noddy (Anous minutus) and Brown Noddy (A. stolidus) from the southern lagoon of New Caledonia

The Black Noddy (Anous minutus) and the Brown Noddy (A. stolidus) occur sympatrically in the Southern Lagoon of New Caledonia, breeding on islets located at the edge of a wide, productive coral-reef lagoon next to oceanic waters enriched by a seasona...

Characterization of Alkaliphilus hydrothermalis sp nov., a novel alkaliphilic anaerobic bacterium, isolated from a carbonaceous chimney of the Prony h...

A novel anaerobic, alkaliphilic, Gram-positive staining bacterium was isolated from a hydrothermal chimney in the Prony Bay, New Caledonia. This strain designated FatMR1(T) grew at temperatures from 20 to 55 A degrees C (optimum 37 A degrees C) and a...
