Cod Stocks Plummet: Bay of Fundy's Future Uncertain

Atlantic cod populations in the Bay of Fundy and on the Scotian Shelf continue to struggle, with recent assessments highlighting a dire situation. Data from 2024-25 indicates the lowest recorded numbers of young cod and alarmingly high mortality rates. These stocks have been classified as critically endangered since approximately 2008 and show no signs of improvement.

Scientists are uncertain about the precise reasons behind the persistent decline, suggesting a combination of factors such as increased predation and warming ocean temperatures may be at play. The assessment also points to a reduction in the age structure of the cod population, with older fish having not been observed in surveys or bycatch since the 1990s. This species is primarily caught as bycatch, with a limited total allowable catch of 660 metric tonnes.

While management responses have been noted as positive, marine conservationists emphasize that recovery is exceptionally difficult for populations that have already collapsed. Weaker stocks are more susceptible to environmental pressures and other ecological challenges, akin to a vulnerable individual contracting a secondary illness. Climate change is also identified as a significant factor, particularly in areas like the Gulf of Saint Lawrence and parts of the Scotian Shelf experiencing accelerated warming, further impacting these vulnerable fish stocks.
