Discussing fishing, the fishing rights in the North Sea, Atlantic amnd Scandinavian seas were decided by the London Fisheries Convention of 1964. Of the signatories to this only Italy and Luxemborg ( one which has no fishing industry, the other too far away from the North Sea/Atlantic areas to make a difference) were then included in the CFP.
Furthermore, the UK currently has the largest fishing ports in the EU, Fraseborough and Peterhead.
Changes to the rules about where different nations were allowed to fish came in 1976, when the 12 nautical mile exclusive zones were extended to 200.
This greatly benefited the UK because having lost the Cod wars with Iceland ( finally decided 1973/4) the traditional fishing areas agreed in the 1964 agreement were no longer fished by UK fishermen and they now had to come back in to fish in areas traditionally used by other countries.
The UK government chooses who gets quotas, and has a policy of selecting large firms atm.
Oh and please don't mention Farage and fishing, he had his chance to make a difference, he didn't, but chose to grandstand on the Thames instead, he is exactly what Geldof called him, a fraud.
