So what is the best solution we can implament Norm, assuming we have an open wish-list that goes beyond burning all their boats?
EASY, a total allowable catch with NO discards. An area can support a certain amount of fish so they , DEFRA, give it a TAC, a total allowable catch. So many tons of, cod, haddock plaice, you name it, DEFRA have a TAC for it. Divide that by the boats with a licence or licences. Say a TAC of 5,000 tons, total, per boat. Video, sat nav, lie detectors, you name it, they, DEFRA, use it. When a boat has caught it's TAC it's laid up for the rest of the year. If they catch rubbish fish, bad luck, learn. If they catch quality fish, good luck, experienced skipper. No discards, if they're over their TAC it's taken out of next years quota. TACS/rules to be enforced with £1,000,000 fines and loss of boat and licence for ever, second or subsequent offences, 5 years in prison, not options. Try it, not many will cheat, well not more than twice.
