They don't rely much on fish runs, they prefer big game, shellfish and then small game in winter, mostly berries and wild vegetation in summer. If fish runs were their food source they would have left this area long ago.

The ones out here eat a shatload of clams and oysters in winter on nightime tides, tracks are washed away by daylight by the incoming tides.

Shellfish is the lowest effort, highest nutritional yield avialable, and plentiful.
