Assessment of pelagic fish stocks in the North Sea and North Atlantic
Data on population parameters of pelagic fish stocks (herring, mackerel, horse mackerel, blue whiting and sprat) in the North Sea and North Atlantic are combined with catch records and landings statistics and provide input for the fish stock assessments of ICES. The results of these calculations serve as a basis for sustainable fisheries management.
Background and Objective
We participate in the annual international programs to identify population parameters of the pelagic fish species herring, mackerel, horse mackerel, blue whiting and sprat in the North Sea and North Atlantic. These data are combined with catch records and landing statistics, catch and bycatch records and sampling information from the commercial fleet and provide input for the fish stock assessments of the international ICES working groups. The results of these calculations serve as a basis for political decisions in the framework of the European Common Fisheries Policy (CFP) and in international agreements. The aim of this task is to provide real-time information on the development of commercially exploited fish populations to facilitate a sustainable management of the resources.
The four most important fish species for the German fishery (in terms of landings) are pelagic species. In the North Sea and the Northeast Atlantic, the stocks of North Sea herring, Northeast Atlantic mackerel, western horse mackerel and blue whiting are of special interest for the fishery, which is mainly conducted by large pelagic freezer trawlers. For the first two stocks, management regimes have been internationally implemented over the last decade. Both stocks are in very good condition, and present catches are sustainable. The TI-SF participates in both most important surveys and a number of other international programs for the determination of fishery-independent parameters.
