In 1968 the cod catch peaked at 810,000 tons, approximately three times more than the maximum yearly catch achieved before the super-trawlers. Around eight million tons of cod were caught between 1647 and 1750 (103 years), encompassing 25 to 40 cod generations. The factory trawlers took the same amount in 15 years. [14]
Atlantic cod stocks were severely overexploited in the 1970s and 1980s, leading to their abrupt collapse in 1992. [1]Overexploitation, also called overharvesting or ecological overshoot, refers to harvesting a renewable resource to the point of diminishing returns. [2]
Jack mackerel caught by a Chilean purse seiner Fishing down the food web. Overfishing is the removal of a species of fish (i.e. fishing) from a body of water at a rate greater than that the species can replenish its population naturally (i.e. the overexploitation of the fishery's existing fish stock), resulting in the species becoming increasingly underpopulated in that area.
Cod (pl.: cod) is the common name for the demersal fish genus Gadus, belonging to the family Gadidae. [1] Cod is also used as part of the common name for a number of other fish species, and one species that belongs to genus Gadus is commonly not called cod (Alaska pollock, Gadus chalcogrammus).
Canadian Atlantic cod (Gadus morhua) are cold water fish weighting 2–3 kilograms (4.4–6.6 lb) in the wild. [1] Atlantic cod were originally found in the Atlantic Ocean, along the borders of both Canada, England and throughout the United States. Heavy fishing in the late 1800s and early 1900s, led to a massive decline in the cod population. [2]
There have been multiple notable examples of such an ecosystem collapse in the recent past, such as the collapse of the Atlantic northwest cod fishery. [10] More are likely to occur without a change in course, since estimates show that 87% of oceans and 77% of the land surface have been altered by humanity, with 30% of global land area is ...
