Collapse of the Atlantic northwest cod fishery. The Atlantic fishery abruptly collapsed in 1993, following overfishing since the late-1950s, and an earlier partial collapse in the 1970s. [1] It is expected to recover to historical, sustainable levels by 2030. [2]
Cod fisheries. Cod fisheries are fisheries for cod. Cod is the common name for fish of the genus Gadus, belonging to the family Gadidae, and this article is confined to three species that belong to this genus: the Atlantic cod, the Pacific cod and the Greenland cod. Although there is a fourth species of the cod genus Gadus, Alaska pollock, it ...
Cod fishing on the Newfoundland Banks. Cod fishing in Newfoundland was carried out at a subsistence level for centuries, but large scale fishing began shortly after the European arrival in the North American continent in 1492, with the waters being found to be preternaturally plentiful, and ended after intense overfishing with the collapse of the fisheries in 1992.
The Atlantic cod (pl.: cod; Gadus morhua) is a fish of the family Gadidae, widely consumed by humans. It is also commercially known as cod or codling. [3] [n 1]In the western Atlantic Ocean, cod has a distribution north of Cape Hatteras, North Carolina, and around both coasts of Greenland and the Labrador Sea; in the eastern Atlantic, it is found from the Bay of Biscay north to the Arctic ...
Technological advances in fishing (such as using large factory-ships and sonar), as well as geopolitical disputes over territorial sea and exclusive economic zone (EEZ) boundaries, led to overfishing and a serious decline in the fish stocks of the Grand Banks from around 1990. The Canadian Grand Banks fishery was closed in 1993. [10]
On July 2, 1992, the Honourable John Crosbie, Canadian Federal Minister of Fisheries and Oceans, declared a two-year moratorium on the Northern Cod fishery, [68] a designated fishing region off the coast of Newfoundland, after data showed that the total cod biomass had suffered a collapse to less than 1% of its normal value. [69]
The collapse of the Atlantic northwest cod fishery off Newfoundland, [22] and the 1992 decision by Canada to impose an indefinite moratorium on the Grand Banks, is a dramatic example of the consequences of overfishing. [23]
But during the 2018-2019 heat wave, Pacific cod were able to go to these warmer-than-usual waters and ate a portion of what was left of the snow crab population.
