Abstract: The main goal of this paper is to improve the understanding of the spatial distribution of small-scale inshore fisheries (SSF) in coastal waters of the Bay of Biscay. The study used a participatory process, in which fishers, regional administration, and researchers were involved in supplying the data. Displayed on a 1-km(2) grid, the data for effort and catch composition, variable costs, revenue, and profits at each site show the spatial patterns of the main SSF metier activities. This information indicates the economic value of the fishing grounds and the cost of reaching those areas, which can reveal possible trade-offs for more distant fishing grounds. Trammelnet vessels are widely dispersed, following economic incentives, while longliners also demonstrate high mobility, using many fishing sites, though the economic incentive does not always lead to high benefits. A narrow expansion range with activity close to the coastal area (trap, gillnet, and trammelnet users) suggests that the target-species stocks maintain their economic profitability even though it is lower than that in other coastal fleets. Such information helps develop a holistic approach to SSF management in this multi-use region by increasing the availability of high-quality multidisciplinary geospatial data, currently in short supply for this fleet.
