AbstractThe red shrimp Aristeus antennatus is the most important deep-sea demersal resource in the NW Mediterranean. In NE Spain it is fished by bottom trawling at the depths between 200 m and 900 m, and the fishing grounds are allocated around the margins of a system of submarine canyons, where it constitutes the only target species. This fishery is characterized by marked seasonality, with higher levels of landings occurring in summer. Combining Vessel Monitoring System data (VMS) with daily landings has the potential to substitute logbook data for stock evaluations, avoiding human error or misreporting. Also, when landings per size class are available, this approach allows the identification of the critical areas and/or periods for the exploitation of the smallest size classes in the population, constituting the basis for specific management decisions such as the establishment of protected areas or temporary fishery closures. The main objective of this study was to map and investigate the spatiotemporal distribution of the landings per size class of red shrimp in the fishing grounds of two of the main fishing ports of NE Spain, Blanes and Palamós
