Wow, can you ever tell it's a slow posting period, or what?!
I grew up catching (chain) pickeral in NJ. Kind of a "mini pike", getting me ready for the bigger stuff in later years. I was puzzled to hear some call walleye "pickeral". Think this is a north of the border term for walleye (?) I agree with CCB: 2 different species, technically, if you ask me.
But: who really cares
what they're called, as long as they are on your line?
(Reminds me of the "Jackelope"...does anyone know what I'm talking about.....!?........I'm punchy these days with all the bad luck flying about.) It's like dodging bullets here, there's so much whizzing around.) Anyway, a "pickerwall" or "wallpick" or whatever(!) would make an amusing illustration.
