I did not eat the cisco. I was fishing northern Quebec at the time, after landing it the local I was fishing with called it an F#&%ing chub and proceeded to kill the fish and toss it overboard. He explained the cisco's are out competing game fish for food, and they grow quickly which only makes them prey for large predators like pike. It was very shocking, and to this day I'm still confused by it still think it was the wrong, but who was I to say.
