Alaska's salmon and pollock sectors will count 2018 as one of their best in years, thanks to brisk global demand and tightening supplies of both whitefish and salmon.

Garrett Evridge, an Alaska-based fishery economist with the McDowell Group, told an audience Sunday at Pacific Marine Expo (PME) in Seattle the state's 2018 salmon season ranks as one of the most valuable on record, even though volumes were down.

"It's an interesting dynamic with low volume, but everything we caught was worth a lot," he said.
