The use of fishers' knowledge through geographical information systems (GISs) is increasingly considered as a promising source of local information on small-scale coastal fisheries. In this paper we describe the first framework for mapping entire small-scale coastal fisheries using fishers' knowledge on catch size and fishing effort. Four mangrove and coral reef fisheries targeting invertebrates or finfish in New Caledonia (southwest Pacific) were mapped following a five-step framework: (i) stratified random sampling of regular fishers; (ii) collection of fishers' knowledge of fishing areas, fishing effort, and catch size through map-based interviews; (iii) data integration into a spatial geodatabase; (iv) statistical extrapolation of fisher data to the fishery scale; and (v) mapping of catch, effort, and catch per unit effort (CPUE) for each fishery using a GIS overlay procedure. We found evidence that fishers' knowledge supplied precise and accurate quantitative and spatial information on catch size, fishing effort and CPUE for entire fisheries. Fisheries maps captured the fine-scale spatial distribution of fishing activities in a variety of ways according to target taxa, gear type, and home ports. Applications include area-based marine conservation planning and fishery monitoring, management, and governance. This integrated framework can be generalized to a large range of data-poor coastal and inland small-scale fisheries. specialized fisheries mapping fishers' knowledge map-based interviews participatory GIS small-scale coastal fisheries spatial fisheries management NOUVELLE CALEDONIE OCEAN PACIFIQUE 040 126 71 7 1781-1792 2014 1054-3139 https://www.documentation.ird.fr/hor/fdi:010062633 10.1093/icesjms/fst204 1054-3139 [F B010062633] https://www.documentation.ird.fr/hor/fdi:010062633 https://www.documentation.ird.fr/intranet/publi/2014/11/010062633.pdf Accès réservé (Intranet de l'IRD) IRD - Base Horizon / Pleins textes 2014-12-05 2017-08-23 fdi:010062633 fre
