Today in History—July 2: The Canadian Cod Fishery Collapse

On this day in 1992, the Canadian government confirmed what thousands of people in Newfoundland and Labrador already knew: Cod fishing—and life as they knew it—was over.

North Atlantic cod had supported the province for half a millennium, at one point supplying as much as 60 percent of the fish eaten in Europe. Entire communities were built around the fishery, and more than 10 percent of the province’s population worked in the industry. Some fishing families could trace their involvement back six generations. Handline catches and small-scale fishing were a way of life.

In 1885 the Canadian Ministry of Agriculture declared the cod supply simply inexhaustible.

On July 2, 1992, the Canadian Ministry of Fisheries declared it exhausted.

At a press conference in a hotel ballroom in St. John’s, the province’s capital, officials announced a two-year moratorium on cod fishing to give the population stocks time to recover. Angry fishermen stormed the ballroom. Security guards barricaded the doors with chairs and called for reinforcements.

The announcement triggered the largest mass layoff in Canadian history.

The collapse had been decades in the making. In 1885 no one could have imagined the effects of radar, sonar, refrigeration, and factory trawlers that enabled fishers to find, catch, process, and freeze unthinkable quantities of cod—all without ever returning to shore. Quotas remained high, based on flawed and wildly optimistic population estimates. Industrial fishing, poor management, and destructive and indiscriminate bottom trawling by ships the size of city blocks left too few fish to breed and replenish the population.

The two-year moratorium was renewed again and again. Cod are slow to grow and reproduce, and the effects of climate change—warming their waters and reducing their preferred prey—didn’t help.

Coastal communities were decimated. Unemployment in the province peaked at 20 percent, and within a decade, Newfoundland and Labrador had shed 10 percent of its population. The Canadian economy forfeited hundreds of millions of dollars every year the ban remained in place.

A cautiously managed commercial cod fishery reopened in 2024. But the collapse of North Atlantic cod remains a stark reminder that nothing is inexhaustible.
