The cross shelf distribution of coral reef fishes according to their trophic structure is examined for 123 visual transects in the SW lagoon of New Caledonia. Abundance is maximum nearshore whereas biomass is evenly distributed across shelf. Piscivores (4-19 % of biomass) are dominated by serranids, with increasing numbers of lutjanids and carangids near the barrier reef, the latter being characterized by mullids and lethrinids. Small, abundant species are differentially distributedd, pomacentrids, dominating nearshore, are gradually replaced by apogonids and Anthias spp. near the barrier reef. Grazers are the main group in biomass but their importance decreases from 65 % on the coast to 28 % on the barrier reef. Scarids, the main component of grazers (> 50 % of biomass) show an even cross shelf distribution, whereas acanthurids in biomass from 19 % on the coast to 46 % on the barrier reef, siganids showing the opposite trend. Comparison with the neighbouring Great Barrier Reef indicates some analogies such a close species pool, similar biomass distribution of large grazers, of several families of invertebrates feeders and planktivores
