Cod Wars Third Cod War (November 1975 – June 1976) began after Iceland again extended its fishing limits, now to from its coast. The British government did not recognise the large increase to the exclusion zone and so an issue occurred with British fishermen and their activity in the disputed zone. The conflict, which was the most hard-fought of the Cod Wars, saw British fishing trawlers have their nets cut by the Icelandic Coast Guard, and there were several incidents of ramming by Icelandic ships and British trawlers, frigates and tugboats. One of the most serious incidents occurred on 11 December 1975.
History of fishing lasted for more than 1000 years, passing through periods of Black Death, wars and other crises and still is an important Norwegian fish trade. The Portuguese have been fishing cod in the North Atlantic since the 15th century, and clipfish is widely eaten and appreciated in Portugal. The Basques also played an important role in the cod trade and are believed to have found the Canadian fishing banks in the 16th century. The North American east coast developed in part due to the vast amount of cod, and many cities in the New England area spawned near cod fishing grounds.
