Spatial Characterization of the Artisanal Fisheries in the Algarve (South Portugal)

Fishing grounds of the artisanal fisheries of the western part of the Algarve (South Portugal) were characterized, determining their sediment and habitat composition, depth and distance to harbor. The data were compiled using GIS software. In this study, the fishing effort was classified and the high fishing effort area of the four main gears types (traps, pots, nets and hooks) favored by local fishermen were examined. The aim was to identify the sediments and habitats chosen by the fishermen. This was calculated by examining the percentage of high fishing effort occurring in the total area of each sediment or habitat present in the study area. In coastal waters, rock, sand and mixed sediment seemed to be favored over others habitats. The characteristics identified for each fishing ground could then be linked with some ecological features and essential habitat of the main target species. Identifying fishing grounds and essential fish habitats can be a tool to understand the distribution of the resource and the dynamics of the fisheries exploiting it.
