Providing food for the whales requires, primarily, changes in location. The harvest needs to shift to areas past the whales. First, of course, is the ending of fisheries on juvenile and immature salmon. Then, fish those that pass the whales.

Another benefit is that the cost in fuel per pound will be reduced as the fish will be significantly larger and closer to "home".

Managers could still use the same escapement goals. It would change fisheries but not eliminate fishing on salmon.
