Do you never get tired of salmon? Evidence for extreme salmon specialization at Prince Rupert harbour, British Columbia

Faunal evidence from five village sites at Prince Rupert harbour, British Columbia reveals very high levels of dependence on one food resource, salmon, during the period from 500 BC to AD 1000. At some of these sites, it appears that little else in the way of vertebrate fauna was consumed. Comparisons with faunal data from other parts of the Northwest Coast show that the Prince Rupert villagers during this period were extreme salmon specialists, as highly focused on this one resource as any the Northwest Coast culture, and among the most highly resource specialized hunter–gatherer cultures worldwide.
