Here is omething to consider:

In the Green/Duwamish river system in the Puget Sound region the hatchery production of summer steelhead has introduced a small wild population where no native summer stock had existed and the juveniles of that introduced stock compete for the food and habitat resources with the native winter steelhead. It would be in the best interest of the native stocks to allow harvest of these non-native wild fish as a means of reducing that competition. The moratorium prevents that from happening.
