Facts from the source article.

Key facts and history

Cod have three rounded dorsal fins and two anal fins, with pelvic fins set under the gill cover.[3] Atlantic cod live in colder waters throughout the North Atlantic, while Pacific cod are found in both eastern and western Pacific regions.[4] Cod has been an important economic commodity since the Viking period around 800 AD.[5] In the 17th and 18th centuries, cod became a major commodity in Massachusetts and Newfoundland.[6]

On July 2, 1992, Canada declared a two-year moratorium on the Northern Cod fishery after the biomass collapsed to less than 1% of its normal value.[7] Dried cod accompanied Norwegians on their travels, which led to the emergence of a market for this product in southern Europe that has persisted for over a millennium.[5] The two-year moratorium was made permanent, and roughly 12,000 tonnes of Northwest cod continue to be harvested each year by local fishers.[8]

What the cited sources add

The same source reports that between the 1960s and 1990s, the cod population declined by as much as 95 percent.[9] A 2019 report commissioned by Oceana Canada estimated that healthy northern cod stocks could support economic activities worth $233 million in 11 years.[9] The Alaska pollock is a member of the cod family, according to a 2014 SeafoodSource article.[10] The same announcement notes that Northern cod is now the largest spawning stock biomass of any cod stock in the world.[11]

Northern Gulf cod remains in the critical zone, with no directed commercial fishery authorized from 2026–27 to 2028–29.[11]
