Collapse of the Atlantic northwest cod fishery
(詳細はFederal Minister of Fisheries and Oceans, John Crosbie, declared a moratorium on the Northern Cod fishery, which for the past 500 years had largely shaped the lives and communities of Canada's eastern coast. The interplay between fishing societies and the resources which they depend on is obvious to almost any observer: fisheries transform the ecosystem, which pushes the fishery and society to adapt.〔Hamilton et al., 195.〕 In the summer of 1992, when the Northern Cod biomass fell to 1% of its earlier level,〔Hamilton and Butler, 1.〕 Canada's federal government saw that this relationship had been pushed to breaking point, and declared a moratorium, ending the region's 500-year run with the Northern Cod.
==Causes of the collapse==
Academics have highlighted these three contributing factors in the eventual collapse of the cod fishery.
