“Genetic analyses conducted in the 21st century show that the blue walleye was not genetically different from the yellow walleye (Sander vitreus), rendering the taxon invalid.”
It’s just a normal walleye with different colour skin.
Caught one on the inner bay in 10 FOW south of bait island a few years ago when the high water was in. I posted a photo of it here. Surprised me enough to ask what it was. I catch yellows regularly. There is a history of blues in Erie. Others here had great info about them at the time.
Bluish walleye as apposed to yellow walleye are common in some areas. While I've only caught yellow pickerel in Lake Erie I caught many of the blue variety in Quebec. We had both kinds in the tributaries of the Ottawa River in northwestern Quebec.
My father who worked for the fishery in picton, Ontario said the blue pigmentation comes from phosphorus and other minerals in the water. Can’t source that info but I have caught quite a few in the far north, nothing around here.
Bleu's from Lac Kipawa..
Agree, the pigment is in the slime, which is blue and seems to be taken up by the fins.
Environment, water colour, bacteria?
Rainy day Blue(s)...
We used to catch a few in West Arm from time to time. Funny enough, we actually caught a Perch with a blue tinge to it there once. I’ll try to round up a picture.
