British boats were excluded from Icelandic waters in 1976. In 1977 a fishing limit was set up by the European Economic Community, and British waters were opened to other Community members. This led to overfishing. Landings decreased 28% between 1967 and 1997, with fishing now mainly off Scotland. Other sorts of fishing also take place on a commercial basis such as for crab, lobster, shellfish and mackerel. Sport fishing is popular from coasts and
Collapse of the Atlantic northwest cod fishery with these new statistics brought to light no changes were made in regards to the allotted yearly catch of cod. With only a limited knowledge of cod biology, scientists predicted that the population of the species would rebound from its low point in 1975 and when Canada extended its fishing boundaries in 1976, fish mortality decreased immediately. This was not due to a rise in cod stocks, it was because foreign trawlers could no longer fish the waters. Therefore, when Fisheries and Oceans set quotas, they overestimated the total stock, and increased the total allowable catch. In 1992, John Crosbie,
