Sardines are seined with big nets in the ocean off the Columbia River. There are only two short seasons (July and September) on these large fish, which can grow up to 10″. They are harvested at their fattest, away from the spawning season.
Remember Steinbeck’s Cannery Row about how fisherman “annihilated” the sardine resource off Monterey California? Well now we know that sardines have been cyclical for eons, disappearing all by themselves, without the help of man. About twelve years ago they showed up again off the Oregon coast in great numbers. An old fishery was renewed after a long absence.
