The glib answer that has often been given to me in the House in years past as to why we should maintain the common fisheries policy is that
fish do not have passports. Of course that neglects the reality that there are three types of stocks: migratory stocks, non-migratory stocks and straddling stocks. We can look at what happens in countries that control their own fisheries, such as Iceland. Jóhann Sigurjónsson, the chief fishing scientist of Iceland, tells me that its fishing has so improved, and trawlers are catching the cod stocks so much more quickly, that fishermen are actually getting frustrated. They are being so successful and doing their work in so little time that they want to go and catch more. That is a sign of their success, having managed their own stocks for a number of decades.
