Resumo: | Fish from lagoon and reef in New Caledonia are mainly caught by artisanal fisheries and subsistence fishing. The present study aimed at estimating these fish standing stocks, at finding the main factors influencing the spatial distribution of these fish, and at estimating the maximum sustainable yield with considerations for socio-economic aspects sensu late. A total of 1406 stations was surveyed in the Northern Province of New Caledonia. Sampling was stratified according to three zones (north, east and west) and three biotopes (coral reefs, near-reef areas and lagoon bottoms). This work demonstrates the existence of important fish stocks of commercial interest in reefal and lagoonal waters of the Northern Province, estimated at about 138 300 t. The standing stocks, which may be considered as non-exploited in the north zone, were mainly composed by large individuals belonging to slow-growing species ('K' strategy). The current catches of fish are globally very low, approximatively 10-times less than the pressure which would achieve a maximum sustainable yield. The characteristics of the local market for fish in New Caledonia, mainly in the Northern Province,:indicate that fish consumption directly reflects fishing pressure. Indeed, subsistence fishing (25.7 kg of fish per inhabitant and per year) represents 92 % of the total fishing pressure, thus the commercial fishing activities may be considered as a minor component. So, it seems that the demography and local feeding habits will probably be the most important factors which will determine the future variations of artisanal fishing activities and status of standing stocks in the northern Province of New Caledonia.
