Characterizing small scale fisheries effort is challenging worldwide. Their functioning is not fully understood due to the lack of information on fishing season, catch effort, and gear types used. This work aims to present different approaches to characterize the Algarve artisanal fishery fleet. The Algarve artisanal fishing fleet is mainly composed of small vessels that target a large variety of coastal species using multiple fishing gears (trammel nets, gill-nets, traps, long-line). The data compiled from various literature will provide baseline information on the catch as well as the evolution of the fleet over the past fifteen years. Methods, such as face-to-face interviews, on board-observations and Automatic Identification System (AIS) data will be used to characterize the spatial distribution of the fishing effort. For example, boat speed obtained through AIS can be used to determine the vessel activity. The fishing effort data collected will then be compiled into a GIS database. This information can be used later on for marine planning such as MPA implementation. It will ensure long term livelihood for the fishing community and a sustainable exploitation of the resource.
