I just wanted to pose this question not only because of the Steady population of of Walleye within Lake Winnipeg that present the Greenback form of Walleye, something seen less often in other Walleye color morphs (Minus the extinct Blue Pike of Lake Eerie). What I've seen of other morphs is that they can either spring up out of nowhere and then vanish like a genetic ghost in the night, or they present solely in the pigments within the outer mucus lining of the fish, this being seen with with Blue Morphs of Walleye where the mucus pigmentation is the reason for the fishes color rather than the pigmentation of the fishes scales themselves, separating them from the extinct Blue Pike form of Walleye.

I'm mostly asking this question as I've struggled to find a Greenback genealogical study, not that its not out there, but I'm not always the best at finding things. I'm very interested in  Populations of Fish Endemic to Single Lakes mostly as a hobby, but it seems the study of Freshwater fish in the Large lakes of Canada can sometimes get overlooked. (I understand the Glacial Ice Sheets kept unique species levels low so less endemism isn't super surprising, but the possibility still excites me) 

If anyone knows any Information or research Pages that would be spectacular, if not I hope you found my speculative thought fun!
