Discard Atlas of North Sea fisheries

The results presented in this discard atlas are based on landings and discards data from the official database of the Scientific, Technical and Economic Committee for Fisheries (STECF) of the European Union. Quantities of landings are derived from the national fisheries statistics which are recorded according to the control regulation (Council Regulation 1224/2009). These include logbook or sales slip records of the volume of landing by species and size grade per management area. Under the European Data Collection Framework, detailed biological data of the biomass, length, age, and species compositions of discards from the most important commercial fisheries are collected via national observer- or self-sampling programmes.
