Wind-induced variability in larval retention in a coral reef system : a biophysical modelling study in the South-West Lagoon of New Caledonia

In the present work, a biophysical dispersal model is used to understand the role of the physical environment in determining reef fish larval dispersal patterns in the South-West Lagoon of New Caledonia. We focus on a reef fish species, the humbug da...

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...

Spatial distribution of small pelagic fish in the lagoon of New Caledonia;Proceedings of the 6th international coral reef symposium

Two acoustic surveys have been done in the lagoon all around New Caledonia, with a digital integrator. The cruises lasting two weeks were done at six month interval. Much information has been obtained on stock biomass and spatial distribution of fish...

Larval Dispersal Modeling of Pearl Oyster Pinctada margaritifera following Realistic Environmental and Biological Forcing in Ahe Atoll Lagoon

Studying the larval dispersal of bottom-dwelling species is necessary to understand their population dynamics and optimize their management. The black-lip pearl oyster (Pinctada margaritifera) is cultured extensively to produce black pearls, especial...

Does coastal lagoon habitat quality affect fish growth rate and their recruitment? Insights from fishing and acoustic surveys

Ensuring the sustainability of fish resources necessitates understanding their interaction with coastal habitats, which is becoming ever more challenging in the context of ever increasing anthropogenic pressures. The ability of coastal lagoons, expos...

Spatial and temporal extension of eutrophication associated with shrimp farm wastewater discharges in the New Caledonia lagoon

Shrimp farming in New Caledonia typically uses a flow-through system with water exchange rates as a tool to maintain optimum hydrological and biological parameters for the crop. Moreover, the effluent shows hydrobiological characteristics (minerals, ...

Girodazole : "from the lagoon of Noumea to cancer patients";Troisième symposium sur les substances naturelles d'intérêt biologique de la région Pa...

Le girodazole est une nouvelle molécule antitumorale isolée à partir de l'éponge #Pseudaxinyssa cantharella$, récoltée en Nouvelle Calédonie. Cette molécule a été sélectionnée pour des études cliniques du fait de sa structure nouvelle, d...

Lagoon islets as indicators of recent environmental changes in the South Pacific – The New Caledonian example

The question of the impacts of climate change and sea level rise on small islands is currently much discussed. The many thousands of Pacific islands in their different contexts (geodynamic, climatic, etc.) and the insufficient data available explain ...
