Última Distribution spatiale des stocks de poissons récifaux démersaux d'intérêt commercial et effort de pêche en Province Nord de Nouvelle-Calédonie (Pacifique occidental) ArchiMer Letourneur, Yves; Labrosse, Pierre; Kulbicki, Michel. 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...

The fish assemblages of two shallow soft-bottom areas located in the Gulf of Fos (NW Mediterranean) were studied by means of 57 trawl surveys carried out on both seasonal and diel scales between 1983 and 1985. A total of 47 fish species was recorded, with a mean density and biomass of 650 individuals ha(-1) and 2.67 kg ha(-1), respectively. Most of the fluctuations observed were on the spatial scale. Strong differences in fish assemblages were observed between the two areas, with both higher species richness and biomass in the outer part of the gulf (La Gracieuse), while a higher density of individuals characterised its inner part (Bay of Carteau). This spatial pattern was due to a small number of species, such as the gobiids Gobius niger and Pomatoschitus...
