Iceland's cod collapse and ITQ recovery (1970s-1990s)
Iceland's cod fishery, the backbone of its economy, collapsed in the late 1970s and early 1980s from sustained overfishing. In 1984 the government introduced individual transferable quotas (ITQs), assigning each vessel a tradable share of the catch.
The quota system was deeply contentious, concentrating ownership and drawing protests from small-boat fishers.
The stock rebuilt over the following decades; Iceland's cod fishery is now MSC-certified and highly profitable, one of the world's best-managed.
Shows a cod stock collapsed by overfishing can rebuild under strict quota discipline — and that recovery takes years, not seasons, and carries real social costs.
