Grimsby, also
Great Grimsby, is an English coastal seaport town and administrative centre in North East Lincolnshire, on the South Bank of the Humber Estuary, close to the North Sea. It was the home port for the world's largest fishing fleet by the mid-20th century, but fishing fell sharply thereafter. The Cod Wars denied the United Kingdom access to Icelandic fishing grounds and the European Union, under its Common Fisheries Policy, parcelled out fishing quotas to other European countries in waters within 200-nautical-mile (370 km) of the UK coast. Grimsby has since suffered post-industrial decline, although food production has risen within the economy since the 1990s. The Grimsby–Cleethorpes conurbation acts as a cultural and economic centre for much of north and east Lincolnshire. Grimsby people are called Grimbarians; the term
codhead is also used jokingly, often for football supporters. Great Grimsby Day is 22 January.
