Effects of geomorphological zones, reefs and seasons on coral reef fish communities of Réunion Island, Mascarene Archipelago, SW Indian Ocean

The echinoderms of the soft bottoms of the South-Western lagoon of New Caledonia;Proceedings of the sixth international coral reef symposium

A bionomic mapping survey of the soft bottoms of the South-Western lagoon of New Caledonia was carried out by dredging. From analysis of the sediments and the fauna and flora found in 489 dredgings, it was possible to define three main benthic commun...

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...

Comparative ichthyotoxicity of shallow and deep water sponges of New Caledonia;Proceedings of the sixth international coral reef symposium

A survey of comparative ichthyotoxicity in marine sponges from shallow and deep water in the Southern province of New Caledonia was conducted. Test fish #Gambusia affinis$ (#Vertebrata, Pisces$) were exposed to aqueous macerates of 30 shallow water a...

Foraminifera in the diet of coral reef fish from the lagoon of New Caledonia : predation, digestion, dispersion

Les foraminifères benthiques marins sont abondants et représentent une source de nourriture potentielle pour les poissons. Les études précédentes des foraminifères dans le régime alimentaire des poissons se sont appuyées sur de petits nombres...

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...

Economic valuation of ecosystem services from coral reefs in the South Pacific : taking stock of recent experience

The economic valuation of coral reefs ecosystem services is currently seen as a promising approach to demonstrate the benefits of sustainable management of coral ecosystems to policymakers and to provide useful information for improved decisions. Mos...
