I did see this from the WDFW site: Now my question is what did the test fishery show this year? Was the commercial session adjusted in response to the test fishery results?

The Management Process

The recreational and commercial salmon fishing seasons for chum are set in the same manner as other salmon fisheries. (See How Salmon Fishing Season are Set Fact Sheet) The basic method is to review the pre-season forecast of abundance and then design fisheries that open in areas and during times when healthy stock predominate and weak stocks are relatively unaffected. Hood Canal Summer Chum are of special concern because of their threatened status under the Endangered Species Act. Consequently, fishing for chum salmon is prohibited in Hood Canal (Catch Record Card Area 12) and Admiralty Inlet (Catch Record Card Area 9) through the summer and early fall.

The fall and winter chum runs in Puget Sound are very healthy. The run size of fall chum is monitored in-season by test fisheries in Area 20 south of Vancouver Island as the fish pass through the Strait of Juan de Fuca and during October in Puget Sound in the vicinity of Apple Cove Point. If these test fisheries indicate the run is either much larger or much smaller than predicted in the pre-season forecast then commercial seasons are adjusted accordingly. Because the recreational harvest of chum is still relatively small, in-season adjustments to recreational fishing seasons focused on chum are rare.
