The EU's Common Fisheries Policy, which began in 1970, aimed at creating a common market for fisheries products by providing for free access to the waters of all member states and introducing structural funds to ensure modernisation of the sector. In 1976 it was agreed that, as from 1 January the following year, member states would extend their exclusive economic zone, which included the limit of their fishing zones, to a distance from their coastlines. In 1980 the EU concluded a fisheries agreement with Spain, which did not become a member of the EU until 1985, which gave the latter (which had the largest fishing fleet in Europe) limited rights to fish in the waters of the member states. In 1983 concerns over the effect that equality of access might have on fishing stocks led to the introduction of certain controls, notably the concept of "total allowable catches" which set maximum quotas of fish which could be caught by each member state, and the British Fishing Boats Act 1983 (BFBA). In 1985, with Spanish accession, everything changed and the BFBA no longer applied to the Spanish fishermen.
