Their initial role was fish trading, but has evolved to include fishing activity management and the administration of all members’ fishing rights and can even extend to proposing conservation and management measures (e.g. limiting landing quantities of small legally marketable fish to improve prices and sustain the stocks). “Cofradías” are now assembled under the umbrella of the PO model in order to access the powers that the EU’s legal framework provides for POs, such as proposing market measures that are extended to other producers. Offshore POs are usually associated with both the South Western Waters RAC, and the North Western Waters RAC. Inshore POs take part in the South Western Waters RAC and the Pelagic RAC.
