Cod stocks were depleted at a faster rate than could be replenished.The trawlers also caught enormous amounts of non-commercial fish, which were economically unimportant but very important ecologically. This incidental catch undermined the stability of the ecosystem by depleting stocks of important predator and prey species.

Technological factors

(File:Time series for collapse of Atlantic northwest cod.png|thumb|300px|Capture of the Atlantic northwest cod stock in million tonnes, with Canadian capture in blueBased on data from the FishStat database FAO.)(File:Time series for Atlantic northwest cod minus Canada.png|thumb|300px|Capture of the Atlantic northwest cod stock in million tonnes, apart from Canada)A significant factor contributing 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 fishers used technology that limited the volume of their catch, the area they fished, and let them target specific species and ages of fish. From the 1950s onwards, as was common in all industries, new technology was introduced that allowed fishers 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.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. The trawlers caught enormous amounts of non-commercial fish, which were very important ecologically. Economically unimportant incidental catch undermines ecosystem stability, depleting stocks of important predator and prey species. Significant amounts of capelin – an important prey species for the cod – were caught as bycatch, further undermining the survival of the remaining cod stock.

Ecology

Poor knowledge and understanding of the ocean ecosystem related with Newfoundland’s Grand Banks and cod fisheries, as well as technical and environmental challenges associated with observational metrics, led to a misunderstanding of data on the “cod stocks” (meaning residual and recoverable fish). Rather than metrics of megatonnage of harvest, or average size of fish,WEB,fisherycrisis.com/, The Starving Ocean, fisherycrisis.com, {{fcn|date=November 2022}} 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.{{sfnp|Cochrane|2000|p=6}} 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 federal government’s priorities were elsewhere.NEWS, Mackerel Wars, Koreatimes, 6 February 2013,www.koreatimes.co.kr/www/opinion/2018/06/197_130118.html , Gwynne, Dyer, 2 January 2023,

Socioeconomic factors

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.{{sfnp|Gien|2000|p=121}} 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.{{sfnp|Gien|2000|p=121}} Additionally, many companies, both foreign and domestic, and individuals had invested heavily in the fishery’s boats, equipment, and infrastructure.

Mismanagement

In 1949 Newfoundland joined Canada as a province, and thus Newfoundland’s fishery fell under the management of the Department of Fisheries and Oceans (DFO). The department mismanaged the resource and allowed overfishing.JOURNAL, Mason, Fred, The Newfoundland Cod Stock Collapse: A Review and Analysis of Social Factors, Electronic Green Journal, 2002, 17, UCLA Library, 152403457, 10.5070/G311710480,escholarship.org/uc/item/19p7z78s, 16 June 2021, free, BOOK, MacDowell, L., 2012, 12: Coastal Fisheries, An Environmental History of Canada, Vancouver, UBC Press, 978-0-7748-2103-2,books.google.com/books?id=j7-803ot3DIC, In 1969 the number of fishing trawlers increased, and coastal fishermen complained to the government.Taking Stock [Motion picture].

This resulted in the government redefining the offshore fishery boundaries several times and eventually extended its limits from {{convert|3|to|200|nmi|km mi|0}} offshore, 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. 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.JOURNAL, Ransom A.

The government wanted to reverse declining fish stocks by removing foreign fishing within the new inshore fishery boundaries. Fish mortality decreased immediately. 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 supply and increased the total allowable catch.JOURNAL, Ransom A. Myers, Jeffrey A. Hutchings, Nicholas J. Barrowman, 1997, Why do fish stocks collapse?

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. 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, 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. The moratorium was at first meant to last two years, hoping that the northern cod population would recover and the fishery. However, catches were still low, and thus the cod fishery remained closed.By 1993 six cod populations had collapsed, forcing a belated moratorium on fishing. 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. The previous increases in catches were wrongly thought to be due to “the stock growing” but were caused by new technologies such as trawlers.Intense fishing pressure also contributed to fisheries-induced evolution in Northern cod. Prior to the collapse of the population, maturation reaction norms of Northern cod shifted towards younger ages and smaller sizes in the decade leading up to the collapse.JOURNAL, 15118724, 2004, Olsen, E.

Impact on Newfoundland

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 find employment.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,{{sfnp|Dolan, et al.|2005|p=202}} 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.{{sfnp|Gien|2000|p=121}} In response to dire warnings of social and economic consequences, the federal government initially provided 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. Newfoundland has since experienced a dramatic environmental, industrial, economic, and social restructuring, including considerable outward migration,{{sfnp|Kennedy|1997|p=315}} and increased economic diversification, an increased emphasis on education. As the predatory groundfish population declined, a thriving invertebrates fishing industry emerged, snow crab and northern shrimp proliferated, providing the basis for a new initiative that is roughly equivalent in economic value to the cod fishery it replaced.

Post-collapse management

In 1997 the Minister for DFO partly lifted the ban on Canadian cod fishing, ten days before a federal election. However, independent Canadian scientists and the International Council for the Exploration of the Sea doubted there had been sufficient recovery.WEB,www.ices.dk/marineworld/recoveryplans.asp, International Council for the Exploration of the Sea, Neil, Fletcher, Will Atlantic cod ever recover?,www.ices.dk/marineworld/recoveryplans.asp," title="web.archive.org/web/20060214020421www.ices.dk/marineworld/recoveryplans.asp,">web.archive.org/web/20060214020421www.ices.dk/marineworld/recoveryplans.asp, February 14, 2006, 2 January 2023, In general, depleted populations of cod and other gadids do not appear to recover easily when fishing pressure is reduced or stopped.JOURNAL, Jeffrey A. Hutchings, 2000, Collapse and recovery of marine fishes, Nature (journal), Nature, 406, 6798, 882–885, 10.1038/35022565, 10972288, 2000Natur.406..882H, 4428364,www.udc.es/dep/bave/jfreire/pdf_conservacion/Collapse_recovery_fisheries%20%28Nature%29.pdf, 2019-02-14,www.udc.es/dep/bave/jfreire/pdf_conservacion/Collapse_recovery_fisheries%20(Nature).pdf," title="web.archive.org/web/20110927052448www.udc.es/dep/bave/jfreire/pdf_conservacion/Collapse_recovery_fisheries%20(Nature).pdf,">web.archive.org/web/20110927052448www.udc.es/dep/bave/jfreire/pdf_conservacion/Collapse_recovery_fisheries%20(Nature).pdf, 2011-09-27, 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. Recognizing faults in processes is not recreational but an essential step in their improvement. In this case much was mishandled. One observer opined “this process stinks”;MAGAZINE,www.canadiangeographic.ca/specialfeatures/atlanticcod/cod.asp, Pauline, Comeau, July–August 1997, Confidential report calls Atlantic cod endangered, Canadian Geographic, 117, 4, 18–22, 2019-02-17,www.canadiangeographic.ca/specialfeatures/atlanticcod/cod.asp," title="web.archive.org/web/20111121014715www.canadiangeographic.ca/specialfeatures/atlanticcod/cod.asp,">web.archive.org/web/20111121014715www.canadiangeographic.ca/specialfeatures/atlanticcod/cod.asp, 2011-11-21, 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“Ottawa Citizen April 18, 1998, p. 1 for some of the ten management (sub) units addressed in the reportWEB,www.ucs.mun.ca/~kbell/cod/BELLcodrep980204/BELLCod980204sbmtd.html, Status of Atlantic Cod, Gadus morhua, in Canada, 2019-02-14, 2021-04-15,www.ucs.mun.ca/~kbell/cod/BELLcodrep980204/BELLCod980204sbmtd.html," title="web.archive.org/web/20210415125455www.ucs.mun.ca/~kbell/cod/BELLcodrep980204/BELLCod980204sbmtd.html,">web.archive.org/web/20210415125455www.ucs.mun.ca/~kbell/cod/BELLcodrep980204/BELLCod980204sbmtd.html, 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 characterized as “a plan to make it late.“WEB,www.ucs.mun.ca/~kbell/cod/i_CSWC.html, COSEWIC: armpit-length committee, K.N.I., Bell, Memorial University of Newfoundland, 2 January 2023, Press interest before the 1998 meeting 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 ... it is as good as I have ever seen in regards to content.” COSEWIC had already attempted to alterWEB,www.ucs.mun.ca/~kbell/cod/CORRESP/CODcoverALTRD-UNETH.htm, Letter to Cosewic members, April 10, 1998, 2 January 2023, the 1998 report unilaterally. The report remains one of an undeclared number that is illegally suppressed (COSEWIC refuses to officially release it unless it can change it “so that it ... reflects COSEWIC’s designation“), in this case despite kudos from eminent reviewers of COSEWIC’s own choice.WEB,www.ucs.mun.ca/~kbell/cod/CORRESP/IN/Reviews96_8-ScottNelson_.htm, Reviews of the Report*: Status of Atlantic Cod, Gadus morhua, in Canada, 2 January 2023, 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; either defense would involve explicit violations of ethics, of COSEWIC’s procedures at the time, and 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. It could not acknowledge or explain the contrast between areas where conservation measures were needed and areas where opposite observations were gaining press attention.WEB,www.ucs.mun.ca/%7Ekbell/cod/SARA/TelForum/BELL041020_Cod_Listing.htm, Endangered Cod, Red Herrings, Harps, and Hamster Wheels, K.N.I., Bell, 2 January 2023, 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.

The potential designation change (from Not At Risk to Endangered) was highly contentious because many considered that the collapse of Atlantic Cod had ultimately resulted 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 DFO had offered 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 author discovered the unauthorized “edits,” 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.WEB, Bell, Kim N. I., Cod: what happened?

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 its designation variation 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 that political pressure by the DFO within COSEWIC was what accounted for the difference.In 1998 in a book, Bell arguedCONFERENCE, Bell, K. N.

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.WEB,www.worldwildlife.org/who/media/press/2004/WWFPresitem711.html, WWF – No more cod in 15 years, WWF report warns, Worldwildlife.org, 13 May 2004, 22 September 2010, 10 August 2010,www.worldwildlife.org/who/media/press/2004/WWFPresitem711.html," title="web.archive.org/web/20100810145832www.worldwildlife.org/who/media/press/2004/WWFPresitem711.html,">web.archive.org/web/20100810145832www.worldwildlife.org/who/media/press/2004/WWFPresitem711.html, Ã…smund Bjordal, director of the Norwegian Institute of Marine Research, disputed the WWF’s claim, noting the healthy Barents Sea cod population.WEB, Tisdall, Jonathan,www.aftenposten.no/english/local/article319556.ece, Cod not endangered species, Aftenposten.no, 25 April 2002, 22 September 2010,www.aftenposten.no/english/local/article319556.ece," title="web.archive.org/web/20080629194826www.aftenposten.no/english/local/article319556.ece,">web.archive.org/web/20080629194826www.aftenposten.no/english/local/article319556.ece, 29 June 2008, 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.

The local ecosystem seemed to have changed, with forage fish, such as capelin, which used to provide food for the cod, increase in numbers, and eat the juvenile cod.

• A Canadian scientist reported that, cod were increasing in numbers, health, normalizing in maturity and behavior, and offered a promising estimate of increased biomass in particular areas.
• 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 generalization of local estimates and ignorance of environmental factors in the 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.NEWS, Goode, Erica, Cod’s Continuing Decline Linked to Warming Gulf of Maine Waters,www.nytimes.com/2015/10/30/science/cods-continuing-decline-traced-to-warming-gulf-of-maine-waters.html, The New York Times, 29 October 2015, JOURNAL, 1, Pershing, Andrew J., Alexander, Michael A., Hernandez, Christina M., Kerr, Lisa A., Le Bris, Arnault, Mills, Katherine E., Nye, Janet A., Record, Nicholas R., Scannell, Hillary A., Scott, James D., Sherwood, Graham D., Thomas, Andrew C., Slow adaptation in the face of rapid warming leads to collapse of the Gulf of Maine cod fishery, Science, 13 November 2015, 350, 6262, 809–812, 10.1126/science.aac9819, 26516197, 2015Sci...350..809P, free,

In June 2018, the federal government reduced the cod quota, finding that the cod stocks had fallen again after just two years of fair catches.
