ASTORIA — One skipper said it was his worst season in 15 years of fishing. Another classified it a “weird” year with scattered schools and undersized fish. For a second straight year, the news hasn’t been good for Oregon and Washington commercial tuna fisherman. According to official figures from the Pacific Fisheries Information Network (PFIN), commercial landings are down from the previous year, dropping significantly from the 10-year average in both states. August has historically accounted for a majority of the tuna caught in a given season, but this year substantial schools arrived later than anticipated, after a majority of commercial fishermen left or turned their attention to other fisheries.
