Case study 5 - Data rich stock Greenland halibut (Reinhardtius hyppoglossoides) stocks in the NAFO area

Case study coordinator: IEO (Spain) 

This Case Study is included in DEEPFISHMAN as a data rich stock, outside of the NE Atlantic. It is carried out by the Instituto Español de Oceanografía (IEO) and the Instituto Nacional de Recursos Biológicos (INRB-IPIMAR). IEO and IPIMAR will liaise with DFO (Canada) who will contribute as part of its own projects. The Greenland halibut stock in NAFO Subarea 2 and Div. 3KLMNO is considered to be part of a biological stock complex, which includes also NAFO Subareas 0 and 1. Prior to the 1990s Canada was the main participant in the fishery followed by USSR/Russia, Denmark (Faroe Islands), Poland and EU-Germany (GDR before 1989) fishing primarily in Subarea 2 and Division 3K. Since then the major participants in the fishery are EU-Spain, Canada, EU-Portugal, Russia and Japan. All except Canada fish in the NAFO Regulatory Area (NRA) mainly in Divisions 3LM and to a lesser degree in Divisions 3NO. In 2003 the NAFO Fisheries Commission implemented a fifteen years rebuilding plan for this stock.
