Morphology





Blue walleye of Canada are genetically different than the extinct "blue pike" of Lake Erie. They are albino for yellow color and have blue color in the mucous of their skin. The blue color forms on the dorsal (upper) part of the body and is particulary noticable in the two dorsal fins and the upper part of the tail.

I have gaught many Blue Walleye in Lac Gilberte, Quebec which is about 60 miles north of Mont Laurier. Average size is 15 to 22 inches and they are excellent eating. Lac Gilberte has only the blue ones.

Lots of soft blue clay in lakes in my area . Kenora Ontario.Possible theory that either vegitation growing in clay is eaten by cray fish or others than eaten by fish.Walleyes tend to forage close to the bottom and also may eat the residue of blue clay well they are feeding.The blue in the fish in our area is even in the flesh of the walleye.This is just a nother hypothisis.Email address . wendy13c@shaw.ca

Every fall we catch dozens of blue walleye, the flesh has a blue hue to it. Sowden Lake area. It seems that they are in all the little lakes around here

I was recently fishing in CRANE LAKE by ORR in northern MINNESOTA and we caught a blue walleye and a regular walleye at the same time . Your information was very helpful as the only person I talked to that knew any thing about blue walleye was our director of area fisheries Chris Kavanaugh. Thank You , Brian

In 1998, i caught a Blue Walleye @ Restoule Lake Prov. Park in Ont. Part of the French River System. I knew what it was because my Family use to catch them in a lake along the Can. Nat. R.R. noth of Parry Sound, south of the French River, back in the mid 20's to the mid 40's. Over the years i have been told that there was no such thing, or Blue Pike either.
I use to catch, what we called Blue Pike, North of Kirkland Lake, Ont. on the East Side of Hwy. #11, North of Kenogami, back in 1969,70. Ike, alwaysyours@rogers.com

We went fishing at the end of July 2008 to Whitewater Lake, just N of Armstrong ON. We caught lots of blue walleye in this lake, but in one spot only.

I Haven't caught any Blue Walleye yet, but just recently was fishing a small lake near Rabbit Lake (Temagami Ontario Region) and all the walleye we caught had that intense "Sandercyanin" mucous first time I've noticed this.

Dear Anonymous: Thank you for your sighting of blue slime on the fish near Rabbit Lake. The phenomenon is spreading. We hypothesize the spread is due to increased ultraviolet radiation from the sun hitting the earth in Canada because of depletion of ozone over the north pole. Sandercyanin does not hurt the fish or the fish meat. Good fishing. Wayne Schaefer

I just returned from fishing in Northwestern Ontario and the topic of the Blue Walleye came up. The area is near Savant Lake, which is roughly 85-90 miles north of Ignace.

There are four lakes in question here:

Harold: 50.327557,-90.610828
Harris: 50.270394,-90.645475
Handy: 50.359765,-90.584049
Conant: 50.363456,-90.615778

I've fished all four and the walleyes that come out of each are very distinctive. The fish in Conant and Harris have the typical coloring with the dark back, yellow sides and faded almost white belly. The fish in Harold have a much darker, yellow belly. The fish in Handy will very often have the blue/gray coloring with no yellow on them at all. I've fished a number of other lakes in the area and I've never seen this blue coloring in any other than Handy.

Harold and Handy are connected via a small river/stream on the north end of Harold and are right next to each other. I don't understand why this blue color would manifest itself in this one lake but not in any others in the area.

Dr. I have several questions:
1.Are theese fish born this color?
2. you say they are albino of yellow, so are theese fish albino then pick up this blue protein?
3. do they stay this color in the winter under the ice?
