I remember going out of Port Colborne for Blues with dad in the mid fifties , they were a small pickeral , average a pound and a half maybe rarely over 2, we would anchor deep water much like perching today and use minnows. Yellows were a trolling game , June Bug spinners were popular with a worm on the hook, they pulled like crazy for a 6 year old
edit: we called them Blue Pickerel the Yanks from Buffalo called them Blue Pike
