When I fished the western basin of Lake Erie out of Colchester harbour with my Dad back in the mid 40s, he said we were fishing for pickerel. So for years, I called them pickerel too. After listening to so many Americans referring to the same fish as walleye, like aplumma, I did some research. And I too learned that the correct name for my favourite eating fish, Sander vitreus , was actually walleye. Consequently, I haven't been pickerel fishing for a long time. Au contraire, I've been and continue to go walleye fishing. Even so, it doesn't bother me much that so many Ontario fishermen refer to this fish as a pickerel. Old habits are difficult to overturn.
