AbstractKnowing the principal factors affecting the spatial distribution of marine resources is pivotal to evaluate their spatial distribution, predict and mitigate the potential impact of human activities and design accurate and effective management actions. In this study, we aimed to model the fishing niche of the burrowing decapod Nephrops norvegicusm(Norwegian lobster), an economical important and iconic resource in the Mediterranean Sea. We used a long temporal series of fishing data from 2005 to 2016 from the Northwestern Mediterranean Sea. For each year, we combined accurately spatial fishing information obtained from vessel monitoring system (VMS) with fish landings databases and environmental related,variables (depth and habitat type).,In overall for all years, spatial fishing habitat model output revealed that N. norvegicusin the Northwestern Mediterranean Sea was fished in depths ranging between 50 and 600 meters, with the maximum biomass fished at ~80 and ~400 meters depth. Also, as expected by its burrowing habits, the fishing habitat type of N. norvegicus was dominated by sand and muddy subtracts. Moreover, we found variations in the maximum biomass fished by the fisheries among years, suggesting subtle changes in the fisheries of this demersal crustacean
