Poor production of pink salmon mystifies

In 2016, commercial fishermen have only harvested 8 million pinks as of Aug. 15 in Prince William Sound, the state’s largest pink run. Only one-third are hatchery fish, a marked turn from last years’ massive pink haul of 96 million in the Sound, a 20-year record-breaker over 93 million pinks in 2003. Of these, 80 percent were hatchery fish. Southeast Alaska’s run is doing as badly with only 13.4 million harvested, less than half the already-substandard forecast of 34 million fish. Dan Gray, the area management biologist for Southeast Alaska’s commercial fisheries, said he and fishermen both are stumped as to the poor run’s nature, but seem to think the warm Gulf of Alaska “blob” of 2015, which raised surface temperatures 2 degrees Celsius, has some impact. “Maybe it wasn’t the best thing for high sea survival,” he said.
