Ok Francis I am running with you but let us try this. BOTH tribal and non treaty harvest go selective and achieve a mortality on release ( on paper now ) of say a tenth of a percent. ( fish wheels could do that you know ) Assuming as always the division of impacts stays as it is at present and each user group is capped by its impact %. ( the silly little rule thing kicks in I assume ) I don't see the sports gaining any % of the ESA impact thing so are you saying this would have zero impact on the sports fishery? I can see commercial and tribal catches going off the charts and sports drop as the pool of fish is drastically reduced.

The farther up stream the greater the harvest would reduce the pool of fish. Not arguing your math just the history of probable outcomes with such things.
