Yes, Northern Cod Is Still Far Below Pre-Moratorium Levels — And the Numbers Are Stark
“The northern cod stock remains far below the pre-moratorium TAC of 250,000 tonnes recorded in the late 1980s”
The argument in brief
The claim that northern cod remains well below the pre-moratorium Total Allowable Catch of roughly 250,000 tonnes is true. Despite three decades of partial recovery since the 1992 moratorium, Fisheries and Oceans Canada consistently places the stock in the 'critical zone,' and current commercial harvests run to only a few thousand tonnes per year. The fish simply are not there in the numbers needed to support anything close to 1980s harvest levels.
Data: DFO Historical Catch Records & Stock Assessments
Why it spread
The northern cod collapse is a story people already know and care about, especially in Atlantic Canada where it devastated communities. The sheer scale of the contrast — a quarter-million-tonne fishery reduced to near zero — makes the statistic feel almost too dramatic to be true, which is exactly why it keeps circulating. It is also a story with no comfortable ending yet, so each new assessment renews public interest.
The claim is accurate. Before Canada closed the northern cod fishery in 1992, the Total Allowable Catch for the 2J3KL stock peaked at around 266,000 tonnes in 1988–1989, according to DFO historical catch records. Today, where limited commercial fishing is permitted at all, annual harvests sit in the low thousands of tonnes — roughly 1–5% of that peak. The stock has not recovered.
Fisheries and Oceans Canada's own 2023 stock assessment confirms the northern cod spawning stock biomass remains in the 'critical zone,' well below the threshold scientists call Blim — the point below which serious harm to the stock is considered likely. DFO estimates current spawning biomass at roughly 400,000–500,000 tonnes, which sounds large until you consider that the pre-collapse stock was many times that size and that biomass, not just fish numbers, determines how much can safely be harvested.
The historical baseline matters here. A landmark 1994 study by Hutchings and Myers in Nature documented how the stock fell from peak abundance to near-commercial extinction in just a few years, establishing the scale of the collapse. Oceana Canada's recovery reports go further, estimating current biomass at less than 1% of unfished historical levels — a figure that underlines just how far the stock remains from anything resembling full recovery.
To be fair to the strongest version of the counterargument: there has been genuine, measurable recovery since the moratorium. Scientists and fishers in Newfoundland have noted more cod in inshore areas in recent years, and DFO data does show a slow upward trend. But 'recovering' and 'recovered' are very different things. CBC News coverage of the 2023 DFO assessment noted that scientists and fishers alike agree the stock is nowhere near the biomass levels that would support pre-moratorium harvest volumes.
This story stays in circulation because the northern cod collapse is one of the most dramatic environmental disasters in Canadian history, and the slow pace of recovery keeps it relevant. The contrast between the abundance of the 1980s and today's carefully rationed fishery is genuinely striking. Watch for claims that frame any signs of recovery as proof the crisis is over — the data does not support that conclusion.

The 2J3KL northern cod stock biomass remains at a fraction of its pre-collapse levels. DFO assessments consistently show the stock in the 'critical zone' well below Blim, with spawning stock biomass estimated at roughly 400,000–500,000 tonnes in recent years, far below the historical productive levels that supported 250,000+ tonne harvests.
- ICES/DFO Historical Catch Records – Northern Cod (2J3KL)
Historical records confirm the Total Allowable Catch (TAC) for northern cod reached approximately 266,000 tonnes in 1988–1989 before the 1992 moratorium. Current limited commercial harvests are in the range of a few thousand tonnes annually, reflecting the stock has not recovered to support pre-moratorium TAC levels.

This landmark peer-reviewed study documented the collapse of northern cod from peak biomass levels supporting TACs of 250,000+ tonnes in the late 1980s to near-commercial extinction by 1992, establishing the baseline against which recovery is measured.
- WWF-Canada / Oceana Canada – Northern Cod Recovery Reports
Oceana Canada reports that northern cod biomass remains at less than 1% of its pre-collapse historical levels when measured against unfished biomass, and current stock levels cannot support anything approaching the pre-moratorium TAC of ~250,000 tonnes.

News coverage of DFO's 2023 stock assessment confirmed northern cod remains in the critical zone and that scientists and fishers agree the stock is nowhere near the biomass levels that would support pre-moratorium harvest levels.
