Distribution of fishing intensity of pulse- and beam trawling in the North Sea

Within this study, we quantify the fishing intensity that is allocated at the various sediment- and energy habitats type areas found in the North Sea by selected Dutch bottom fishing vessels. For 2010 traditional beam trawlers and for 2014 pulse trawlers are selected. Trawling frequency, as a measure of impact, equals the surface area covered by the fishing gear per unit time as a fraction of the surface area of a specific habitat.
