For the record, I don't believe the stories, that there is a world shortage of Cod.
Go to the fjords of Norway
or watch the King Crabbers in the Bering Sea on TV, they use big cod as bait for their pots and even the US, has big stocks of cod.
But, we do have a shortage here, only because we allow the French, Belgium and Spanish fleets, to land illegal undersized fish and over quoted amounts, from UK waters, into their countries. Whilst hammering our home grown UK fleet, with penalties and even prison.
EU. madness
