Mapping and monitoring of pressure from fishery on the marine benthic environment is necessary to support an ecosystem approach to fisheries management (EAFM). In many cases this need is not reflected in official fisheries statistics and logbooks, where focus typically is on catch rather than effort. Consequently, most logbook information is not well suited for quantitative estimation of seafloor impact (swept area and impact severity) of the different gears and trips. We developed a method to overcome this information deficiency of official statistics and produced European wide high-resolution fishing intensity maps (total yearly swept area within grid cells of 1*1 minutes longitude and latitude) for 2010, 2011 and 2012. The annual distribution and intensity of bottom trawling on the European continental shelf was analyzed for different management areas and gear groups, distinguishing between surface and sub-surface effects. Fishing pressure indicators were calculated and compared for each management area; i) proportion of area untrawled, ii) proportion of area with an annual swept area intensity ≥ 1, and iii) proportion of area where 90% of the effort is concentrated).
