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 of Maine had led to overfishing despite regulation. Thus, overestimates of stock biomass due to generalisation of local estimates, and ignorance of environmental factors in growth or recovery potential of a cod fishery would lead to mismanagement and further collapse of stocks, through further unsustainable quotas, as in the past.
