I didn't even know that folks out west fished for cod. Many, many years ago, my uncle's family was associated with a part time commercial salmon fisherman and I used to go on the boat to help out. That meant reeling in the tackle (downrigger reels attached to outrigger poles running baits rigged off the main cable), replacing bait, and unhooking the trash fish. Trash fish included cod (not rock cod), whiting (huge 5#) and flounders (aka ping pong paddles), and short salmon. Anyway, we threw back a lot of these, especially the whiting. We kept the occasional flounder, but the rest either went back or was kept for crab bait. Would fish for rockcod on the drift with salmon rods, but in the pre braid days, it was a pain. Regular cod just got tossed back. Wonder if it is still like that.
