A major factor that contributed to the depletion of the cod stocks off the shores of Newfoundland included the introduction and proliferation of equipment and technology that increased the volume of landed fish. For centuries local fishermen used technology that limited the volume of their catch, the area they fished, and let them target specific species and ages of fish.[5] From the 1950s onwards, as was common in all industries at the time, new technology was introduced that allowed fishermen to trawl a larger area, fish deeper and for a longer time. By the 1960s, powerful trawlers equipped with radar, electronic navigation systems and sonar allowed crews to pursue fish with unparalleled success, and Canadian catches peaked in the late-1970s and early-1980s.[9]

The new technologies adversely affected the northern cod population by both increasing the area and depth that was fished, the cod were being depleted until the surviving fish could not replenish the stock lost each year;[10] and secondly, the trawlers caught enormous amounts of non-commercial fish, which were economically unimportant but very important ecologically: incidental catch undermines ecosystem stability, depleting stocks of important predator and prey species. With the northern cod, significant amounts of capelin – an important prey species for the cod – were caught as bycatch, further undermining the survival of the remaining cod stock.

Poor knowledge and understanding of the ocean ecosystem associated with Newfoundland's Grand Banks and cod fisheries, as well as technical and environmental challenges associated with observational metrics, led to misunderstanding of data on the "cod stocks" (meaning residual and recoverable fish). Rather than metrics of megatonnage of harvest, or average size of fish,[11] metrics of the residuum with high variation in the countable population due to sampling error, and dynamic environmental factors such as ocean temperature combined to make it difficult to discern the effects of exploitation to an inexpert regulator.[12] This led to uncertainty of predictions about the "cod stock", making it difficult for the Department of Fisheries and Oceans in Canada to choose the appropriate course of action, when the priorities of the federal government were elsewhere.[13]

In addition to ecological considerations, decisions regarding the future of the fisheries were also influenced by social and economic factors. Throughout Atlantic Canada, but especially in Newfoundland, the cod fishery was a source of social and cultural identity.[14] For many families, it also represented their livelihood: most families were connected either directly or indirectly with the fishery as fishermen, fish plant workers, fish sellers, fish transporters, or as employees in related businesses.[14] Additionally, many companies, both foreign and domestic, as well as individuals, had invested heavily in the boats, equipment and the infrastructure of the fishery.

In 1949 Newfoundland joined Canada as a province, and thus Newfoundland's fishery fell under the management of the Department of Fisheries and Oceans. The department mismanaged the resource and allowed overfishing.[15]

In 1969 the number of fishing trawlers increased, and inshore fishermen complained to the government.[16] This resulted in the government redefining the offshore fishery boundaries several times, and eventually extended its limits from three miles to 200 miles offshore,[15] as part of its claim for an exclusive economic zone under the UNCLOS.

In 1968 the cod catch peaked at 810,000 tons, approximately three times more than the maximum yearly catch achieved before the super-trawlers. Approximately eight million tons of cod were caught between 1647 and 1750 (103 years), a period encompassing 25 to 40 cod generations. The factory trawlers took the same amount in 15 years.[17]

In 1976, the Canadian government declared the right to manage the fisheries in an exclusive economic zone that extended to 200 miles offshore. The government wanted to reverse declining fish stocks by removing foreign fishing within the new inshore fishery boundaries.[15] Fish mortality decreased immediately.[16] This was not due to a rise in cod stocks, but because foreign trawlers could no longer fish the waters. Therefore, when Fisheries and Oceans set quotas, they overestimated the total stock, and increased the total allowable catch.[17] With the absence of foreign fishing many Canadian and U.S fishing trawlers took their place and the number of cod kept diminishing past a point of recovery.[15]

Many local fishermen noticed the drastic decrease of cod and tried to inform local government officials.

In a 1978 white paper, the Newfoundland government stated:[18]

It must be recognised that both the Federal and Provincial Governments, plant workers, and the private sector, which includes fishermen, all have a role to play at influencing and directing the course of development within the fisheries sector. It is essential, therefore, that various interest group conflicts be minimized and that the appropriate measures be taken to ensure that benefits accruing from the exploitation of fish stocks are consistent with rational resource management objectives and desirable socio-economic considerations.

In 1986, scientists reviewed calculations and data, after which they determined, to conserve cod fishing, the total allowable catch rate had to be cut in half. However, even with these new statistics brought to light, no changes were made in the allotted yearly catch of cod.[15] With only a limited knowledge of cod biology, scientists predicted that the population of the species would rebound from its low point in 1975.

In the early-1990s the industry collapsed entirely.

In 1992, John Crosbie, the Minister of Fisheries and Oceans at the time, set the quota for cod at 187,969 tonnes, even though only 129,033 tonnes had been caught the previous year.

In 1992 the government announced a moratorium on cod fishing.[15] The moratorium was at first meant to last two years, hoping that the northern cod population would recover, and along with it the fishery. However, catches were still low,[19] and thus the cod fishery remained closed.

By 1993 six cod populations had collapsed, forcing a belated moratorium on fishing.[17] Spawning biomass had decreased by at least 75% in all stocks, by 90% in three of the six stocks, and by 99% in the case of "northern" cod, previously the largest cod fishery in the world.[17] The previous increases in catches were wrongly thought to be due to "the stock growing" but were actually caused by new technologies such as trawlers.[16]

Approximately 37,000 fishermen and fish plant workers lost their jobs due to the collapse of the cod fisheries; many people had to find new jobs, or further their education to be able to find jobs.

The collapse of the northern cod fishery marked a profound change in the ecological, economic and socio-cultural structure of Atlantic Canada. The moratorium in 1992 was the largest industrial closure in Canadian history,[20] and it was expressed most acutely in Newfoundland, whose continental shelf lay under the region most heavily fished. Over 35,000 fishermen and plant workers from over 400 coastal communities became unemployed.[14] In response to dire warnings of social and economic consequences, the federal government intervened, initially providing income assistance through the Northern Cod Adjustment and Recovery Program, and later through the Atlantic Groundfish Strategy, which included money specifically for the retraining of those workers displaced by the closing of the fishery.[21] Newfoundland has since experienced a dramatic environmental, industrial, economic, and social restructuring, including considerable emigration,[22] but also increased economic diversification, an increased emphasis on education, and a thriving invertebrates fishing industry emerging: as the predatory groundfish population declined, snow crab and northern shrimp proliferated, providing the basis for a new industry that is roughly equivalent in economic value to the cod fishery it replaced.[21]

In 1992, following the early 1990s collapse of Canadian stocks, the Canadian Department of Fisheries and Oceans (DFO) banned fishing for northern cod (that is, cod to the north and east of the island of Newfoundland, in Northwest Atlantic Fisheries Organization areas JKL as shown on this map. This caused great economic hardship in Newfoundland and Labrador. The collapse was blamed on warm water, or harp seals, and it had even been suggested that the cod were still there; only rarely was overfishing acknowledged, or management's role in that.

In 1995, Brian Tobin, the Canadian Federal Minister of Fisheries and Oceans, reopened the hunt on the harp seal, which prey on cod, stating: "There is only one major player still fishing the cod. His name is harp and his second name is seal."[23]

In 1997, inspired by the Grand Banks cod fishery collapse, the Marine Stewardship Council was founded to set global standards for sustainable fishing.

In 1997 the Minister for DFO partly lifted the ban on Canadian cod fishing, ten days before a federal election, although independent Canadian scientists and the International Council for the Exploration of the Sea doubted there had been sufficient recovery.[24] In general, depleted populations of cod and other gadids do not appear to recover easily when fishing pressure is reduced or stopped.[25]

In 1998 the Committee on the Status of Endangered Wildlife in Canada (COSEWIC) assessed Atlantic Cod. COSEWIC's designations in theory are informed by reports that it commissions and by expert discussion in the panel, and it claims to be scientific and apolitical. Recognising faults in processes is not recreational, but an important step in their improvement. In this case much was mishandled. One observer opined "this process stinks";[26] the same observer later joined, and then became Chair of, COSEWIC. COSEWIC listed Atlantic cod as "vulnerable" (this category later renamed "special concern") on a single-unit basis, i.e. assuming a single homogeneous population. The basis (single-unit) of designation and the level (vulnerable) assigned was in contrast to the range of designations including "endangered"[27][28] for some of the 10 management (sub) units addressed in the report[29] that COSEWIC had commissioned from Dr. K.N.I. Bell. That contradiction between the report and the listing reflected political pressure from the DFO; such bureaucratic pressure had been evident through three years of drafts.

The 1998 designation followed on from a deferral in 1997 and bureaucratic tactics including what one COSEWIC insider characterised as "a plan to make it late".[26][30] Press interest before the 1998 meeting[28] had, however, likely deterred a further deferral. COSEWIC's 'single unit' basis of listing was at the behest of DFO, although DFO had previously in criticism demanded (properly, given the new evidence) that the report address multiple stocks. Bell had agreed with that criticism and revised accordingly, but DFO then changed its mind without explanation.

By the time of COSEWIC's 1998 cod discussion, the Chair had been ousted for having said "I have seen a lot of status reports ... [i]t is as good as I have ever seen in regards to content",[26] and COSEWIC had already attempted to unilaterally alter[31] the 1998 report. The report remains one of an undeclared number that are illegally suppressed (COSEWIC refuses to officially release it unless it can change it "so that it ... reflects COSEWIC's designation"),[30] in this case despite kudos from eminent reviewers of COSEWIC's own choice.[32] COSEWIC in defense asserted a right to alter the report or that Bell had been asked to provide a report that supported COSEWIC's designation;[30] either defense would involve clear violations of ethics, of COSEWIC's procedures at the time, and of the norms of science. The key tactics used to avert any at-risk listing centered on the issue of stock discreteness, and DFO's single-stock stance within COSEWIC contradicted the multiple-stock hypothesis supported by the most recent science (including DFO's, hence DFO's earlier and proper demand that the report address these). Bell has argued that this contradiction between fact and tactic effectively painted management into a corner from which it could not acknowledge or explain the contrast between areas where conservation measures were clearly needed and areas where opposite observations were gaining press attention.[33] In effect, DFO's opposition to a listing compromised its ability to carry out its conservation mandate.

In 1998, the Committee on the Status of Endangered Wildlife in Canada (COSEWIC) listed the Atlantic cod as "vulnerable", a category subsequently rebranded as "special concern", though not as an endangered species. This decision process is formally supposed to be informed by Reports that are commissioned from authors. Dr. Kim N.I. Bell authored the 1998 Status Report for COSEWIC.[34][35] This was the first such report on a commercial fish species in Canada. The potential designation change (from Not At Risk to Endangered) was highly contentious, because many considered that the collapse of Atlantic Cod had resulted ultimately from mismanagement by DFO. The Report (section: Author's Recommendation of Status) therefore discussed at great length the process of developing a recommendation for the designation. The Report contained discussion addressing points that had been offered by DFO, because although COSEWIC had a mechanism for the 'jurisdiction' (i.e. the department responsible for the 'species' (here, for the population), to provide objections to an author), it had no mechanism for those objections to be objectively arbitrated as a matter of science. Rebuttal by authors was untraditional and unexpected. That is undoubtedly why, before the meeting which was to decide the designation, COSEWIC had massively unannouncedly edited the Report, thereby introducing many errors and changing meanings, including removing the word "few" from "there are few indications of improvement", and expunging a substantial section which engaged various objections raised by DFO. When the unauthorised "edits" were discovered by the author, COSEWIC was obliged to circulate a letter explaining that it had sent out a version that lacked the author's approval, and had to provide the author's version to members.[36][37]

The Report contained, under a subsection "Designation by geographic management units (as preferred by DFO in 1996)", recommendations (or options) for 10 geographic management units, being Not At Risk or Vulnerable (for 1 management area), Threatened or Endangered (for 5 management areas), and to Endangered (for 4 management areas). In its designation, COSEWIC:

1. Disregarded population structure and provided a recommendation based on the presumption of a single homogeneous population (which even DFO's own internal documents concluded was unlikely, compared to heterogeneity).
2. Disregarded the arithmetic that clearly put declines in high "at risk" categories, and applied a decision of vulnerable, a lower-risk category, to the entire species within Canadian waters.

COSEWIC did not account for the variation of its designation from the Report's recommendation, and did not admit that variation. COSEWIC also refused to release the Report, although its rules required it to. Bell, the Report's author, subsequently stated[38] that political pressure by the DFO within COSEWIC was what accounted for the difference.

In 1998 in a book Bell argued[39] that the collapse of the fishery and the failure of the Listing process were ultimately facilitated by secrecy (as long ago in the defence science context observed by the venerable C. P. Snow[40] and recently cast as "government information control" in the fishery context[41]) and the lack of a code of ethics appropriate to (at least) scientists whose findings are relevant to conservation and public resource management. He wrote that a proper code of ethics would acknowledge the obligations of all to conservation, the right of the public to know and understand scientific findings, the obligation of scientists to communicate vital issues with the public, and would not acknowledge the right of bureaucrats to impede[42] that dialogue, and that to be effective, such ethical issues need to be included in science curricula.

In 1999, Kurlansky in a book wrote that the collapse of the cod fishery off Newfoundland, and the 1992 decision by Canada to impose an indefinite moratorium on the Grand Banks, is a dramatic example of the consequences of overfishing.[43][44]

In 2000, WWF placed cod on the endangered species list. The WWF issued a report stating that the global cod catch had dropped by 70% over the last 30 years, and that if this trend continued, the world's cod stocks would disappear in 15 years.[45] Åsmund Bjordal, director of the Norwegian Institute of Marine Research disputed the WWF's claim, noting the healthy Barents Sea cod population.[46] Cod (known in Norway as skrei or torsk) is among Norway's most important fishery exports and the Barents Sea is Norway's most important cod fishery. In 2015, the Norwegian Seafood Council invited Crown Prince Haakon to take part in opening the year's cod fishing season on the island of Senja.[47]

By 2002, after a 10-year moratorium on fishing, the cod had still not returned.[48] The local ecosystem seemed to have changed, with forage fish, such as capelin, which used to provide food for the cod, increasing in numbers and now eating the juvenile cod. The waters appeared to be dominated by crab and shrimp rather than fish.[48] Local inshore fishermen blamed hundreds of factory trawlers, mainly from Eastern Europe, which started arriving soon after WWII, catching all the breeding cod.[48]

In 2003, COSEWIC in an update designated the Newfoundland and Labrador population of Atlantic cod as endangered, and Fisheries Minister Robert Thibault announced an indefinite closure of the cod fishery in the Gulf of St. Lawrence and off the northeast coast of Newfoundland, thus closing the last remaining cod fishery in Atlantic Canada. In the Canadian system, however, under the 2002 Species at Risk Act (SARA)[49] the ultimate determination of conservation status (e.g. endangered) is a political, cabinet-level[50] decision; Cabinet decided to not accept COSEWIC's 2003 recommendations. Bell has explained[33] how both COSEWIC and public perceptions were manipulated, and the governing law broken, to favour that decision.

In 2004, the WWF in a report agreed that the Barents Sea cod fishery appeared to be healthy, but that the situation may not last due to illegal fishing, industrial development, and high quotas.[51]

In a 2004 book on the subject, Charles Clover claims that cod is only an example of how modern unsustainable fishing industry is destroying ocean ecosystems.[52]

In 2005, the WWF—Canada accused foreign and Canadian fishing vessels of deliberate large-scale violations of the restrictions on the Grand Banks, in the form of bycatch. WWF also claimed poor enforcement by NAFO, an intergovernmental organization with a mandate to provide scientific fishery advice and management in the northwestern Atlantic.[53][54]

In 2006, the Norwegian Institute of Marine Research considered coastal cod (but not the North East Arctic cod) endangered, but has since reversed this assessment.[55]

In November 2006, Fisheries and Oceans Canada released an article suggesting that the unexpectedly slow recovery of the cod stock was due to inadequate food supplies, cooling of the North Atlantic, and a poor genetic stock due to the overfishing of larger cod.[56]

In 2010 a study by the Northwest Atlantic Fisheries Organization found that stocks in the Grand Banks near Newfoundland and Labrador had recovered by 69% since 2007, though that number only equated to 10% of the original stock.[57]

In 2010, Greenpeace International added the Atlantic cod to its seafood red list, "a list of fish that are commonly sold in supermarkets around the world, and which have a very high risk of being sourced from unsustainable fisheries."[58] According to Seafood Watch, cod is currently on the list of fish consumers should avoid. In the book The End of the Line, it is claimed cod is an example of how unsustainable fishing is destroying ocean ecosystems.[59]

In summer 2011, a study was announced that showed East Coast cod stocks around Nova Scotia showed promises of recovery starting in 2005, despite earlier thoughts of complete collapse.[57] It said that on the Scotian Shelf after the cod were gone, the small plankton-eating fish (capelin etc.) that the cod ate multiplied to many times their old numbers and ate cod eggs and cod hatchlings, but in the early 2000s collapsed, giving in 2005 a window of opportunity for the cod to start to recover; but more time and studies were needed to study the long-term stability of the stock increase.

In 2011 in a letter to Nature, a team of Canadian scientists reported that cod in the Scotian Shelf ecosystem off Canada were showing signs of recovery.[60] Brian Petrie, a member of the team, said "Cod is about a third of the way to full recovery, and haddock is already back to historical biomass levels".[61] Despite such positive reports, cod landings continued to decline since 2009 according to Fisheries and Oceans Canada statistics through 2012.[62]

In 2015, two reports on cod fishery recovery suggested stocks may have recovered somewhat.[63][64]

• A Canadian scientist reported that in particular areas, cod were increasing in numbers, health, normalising in maturity and behaviour, and offered a promising estimate of increased biomass.[65]
• A US report suggested that a failure to consider reduced resilience of cod populations due to increased mortality in warming surface water of the Gulf of Maine had led to overfishing despite regulation. Thus, overestimates of stock biomass due to generalisation of local estimates, and ignorance of environmental factors in growth or recovery potential of a cod fishery would lead to mismanagement and further collapse of stocks, through further unsustainable quotas, as in the past.[66][67]

In June 2018, days before this image of an advertisement for cod for sale as fast food in New Brunswick after the long moratorium on the commercial Atlantic northwest cod fishery was taken, the federal government reduced the cod quota, finding that the cod stocks had fallen again after just two years of fair catches.

Seafood Watch says that consumers should avoid some cod populations.[68]
