Global commercial whaling moratorium

The Global commercial whaling moratorium marked a turning point in the regulation of whale hunting, but not a clean end to the whaling era. Instituted by the International Whaling Commission in 1982 and brought into effect in 1987 after a delay for whaling nations to comply, it curbed commercial hunting while leaving contested exceptions and other human-caused threats in place. Its history in the book is therefore one of partial protection: populations began to recover, yet the moratorium remained politically disputed and could not by itself reverse the accumulated damage.

Adoption and Limits

The International Whaling Commission instituted the worldwide moratorium in 1982 at the Metropole Hotel in Brighton. The decision was delayed to give whaling nations time to comply; the measure eventually took effect in 1987. Its arrival followed decades in which whales had been killed and processed on an industrial scale. The book sets the policy against that history, from whale-derived products that supported fortunes and household goods to post-war factory ships that turned catches into food, oil, and animal feed. By the time the moratorium came into force, protection could not simply restore what intensive hunting had removed.

The measure was not a universal prohibition on every form of whale hunting. Subsistence hunts by Inuit communities and other specified groups remained exceptions. Nor did the moratorium end commercial whaling in practice. The book describes continuing hunts conducted under research programs, as well as open commercial hunting by Norway and Iceland. Norway resumed commercial whaling in 1992 and regarded whales as a resource comparable to livestock, while the contested moratorium remained in place as a temporary compromise rather than a settled resolution.

Continued Hunting and Disputed Compliance

The book records substantial killing after the moratorium took effect. It estimates that about 25,000 great whales died in the years that followed. Japan’s Antarctic and North Pacific research programs killed thousands of small and large whales, including minke, Bryde’s, sei, and sperm whales; in 2006, the Antarctic program took 1,073 minke whales and 50 fin whales. The book also notes that Japan killed around 20,000 smaller whales, dolphins, and porpoises each year, animals not covered by the moratorium. The designation of research was itself contested: scientists questioned whether the programs produced information that could not have been collected by non-lethal means.

The policy’s reach was further limited by disagreement about cultural practice and political authority. Whaling nations challenged restrictions as foreign interference in traditions, while conservationists argued that the International Whaling Commission had treated the world’s whale populations as resources to allocate. The book points to the irony that Western governments had encouraged and assisted Japanese whaling after the Second World War, including the use of whale meat in school meals, before later condemning the practice. These reversals made the moratorium not only a conservation measure but also a site of conflict over who could define legitimate use of whales.

Protection Beyond the Hunt

The moratorium addressed commercial pursuit, but whales continued to face risks unrelated to deliberate hunting. The book describes deaths from fishing gear, vessel strikes, noise and chemical pollution, plastic ingestion, and changes in ocean conditions and food supply. It estimates that bycatch kills 300,000 cetaceans annually. Whales move across national jurisdictions and into international waters, so protective rules tied to particular areas cannot follow them everywhere; their exposure to human activity persists beyond the reach of any single conservation policy.

The North Atlantic right whale makes the limits of protection especially visible. Fewer than 400 remained in the North Atlantic in the account, and their population had stayed largely static despite protection from hunting beginning in 1935, changes to shipping lanes, and instructions for vessels to remain 500 yards away. Many were caught in fishing line, while ship strikes killed animals including females of breeding age. Their earlier vulnerability had been linked to traits that made them easy to hunt; those same habits of remaining near the surface and close to shore now expose them to busy shipping routes. The case shows why legal protection from hunting alone cannot ensure a population’s recovery.

Recovery and an Uncertain Future

The book nevertheless records signs of recovery. Humpback and minke whale numbers were increasing in northern and southern oceans; southern right whales were breeding successfully off South Africa and South America; and researchers reported fin whales in greater numbers in the Bay of Biscay and off southern Ireland. Blue whales were also passing through the Irish Sea, a route that had once made them accessible to hunters. Under the moratorium, great whales were reclaiming ancient routes, though the return of animals could also invite renewed claims that their populations were again sustainable enough to hunt.

Recovery remains vulnerable because population numbers alone do not represent the full consequences of depletion. The book notes that hunting can disrupt breeding and social structures, and that removing sperm whales may also destroy cultural knowledge passed between generations. The sperm whale population was growing at only about one per cent annually, a slow rate that makes it difficult to recover from heavy losses. At the same time, the Yangtze River dolphin was declared extinct during the period in which the book was being written, while the right whales of Cape Cod Bay were presented as facing a grave future. The moratorium thus stands as an important restraint, not a guarantee: it reduced one source of pressure while leaving whales exposed to renewed hunting and to the slower, continuing effects of human activity.
