Actually €200 Billion since 1974 according to EU Statistics. At the moment EU Fishery is approximatley €20 billion pa of which 40% of edible fish are fished in Irish territorial waters (90% of which are hauled by non Irish based vessels)

Do you think Ireland has the resources to pull €200b of fish out of the seas?
