Halfway through the season, a commercial summer chum salmon fishery on the Yukon River now appears unlikely. The summer chum return is both late and weak, and well below predicted. The Pilot Station sonar indicates that 65,177 chums have swum up the Yukon as of June 25. The median data for this date is 550,890 fish, which is a difference of almost a half million fish. Data indicates the return at this point in the season is lower than the very weak returns in 2000 and 2001.
