Trevor, I lived in BC when I was a teenager and everyone out there called them Pickerel and I also lived in Alberta for a few years until I retired in 2017 and they were a 50/50 split between Pickerel and Walleye
When I lived out west, Alberta and the NWT 1986-2008 (in the NWT is where I first heard'em called "dore" and had no idea what kind of fish the guy was talking about at the time, but figured it out PDQ.) and in all my extensive travels across western Canada, I heard them called both Walleye and Pickerel. BUT, when I lived there, it was more common to hear Walleye than it was pickerel.
As I said in the post you responded to, "T
he reality is, whether here in Ontario, or elsewhere in this country (and I AM speaking from experience) doesn't really matter whether you call it a walleye or a pickerel, they KNOW what kind of fish you're speaking of, and it has NOTHING to do with Canadian vs Americanisms...it DOES however have everything to do with where you were brought up, and WHAT you were brought up calling this particular fish likely since you were old enough to hold a rod yourself. " It really depended on who I was talking too. Younger people called'em walleye, the older people who have been calling them pickerel since long before I was even a thought called them Pickerel. I didn't care either way because I KNEW what fish they were talking about.
I grew up calling them pickerel because that's what the person who taught me how to fish, my dad, called them. Today, and since long before I moved back here from out west, because I've learned there IS a difference between the walleye and a true "pickerel" they're not even in the same family, I call them walleye because it's "technically" correct. Ultimately tho, I prefer to call'em LUNCH. It's easier and NOBODY gets upset with me about it.
But when someone refers to it as a pickerel when talking to me, I don't get all upset and correct them. No need, because like probably almost, if not everyone else, I KNOW what fish they're talking about. It's NOT a big deal and I don't understand why it seems to be each time this topic of discussion comes up in the forum.
