RETURN OF THE MISSING, THOUGHT TO BE EXTINCT, GREAT LAKES BLUE FISH? UPDATE!

In an earlier video, I talked about a legendary and abundant BLUE FISH that suddenly went missing from the Great Lakes. But then - a fish matching that description started being caught in smaller lakes although the legendary BLUE FISH was said to be extinct. What was happening? I made some speculations and then gathered evidence from hundreds of fishermen and some fisheries scientists. This video is an update on this unfolding mystery.
CALIPER - I mentioned that it would be handy to take a caliper fishing with you and I briefly showed one in the video. They are really helpful for measuring small things like eye diameters. You can get them at local hardware stores or Amazon for $8 to $10 and you will find many uses for it once you have one.
A FORM TO TAKE FISHING - I will attach a form here with some questions all typed up. It would be a good idea to print one and keep it in your tackle box for when you catch your next BLUE FISH. Take a photo of your fish!

NOTE - When I was describing the length of a Blue Walleye's muzzle as being about the width of one of its eyes, I was working from Dr. Schaefer's fish diagrams. If you have an inexpensive plastic caliper with you, you won't have to rely on any such approximations. You can just take a careful measurement and jot it down on "the form to take fishing".

I live nearby Bancroft Ontario and have geard rumours and even seen a picture of blue walleye at one lake nearby. Always wondered why

I think that pockets of people have known about blue walleye in various lakes but A) fishermen tend to be confidential about their secret or favourite lakes, and B) until KZbin and other social media became prevalent, people would only hear about blue walleye through word of mouth or through fishing magazines. But now that knowledge is out there … I expect we’ll be hearing from lots of people who have caught or seen blue walleye. Tell your friends!!!

In the 1990s I seen a walleye caught a tributary of Lake Erie that was extra yellow almost a gold color. It was in the spring spawn I’ve never seen a blue walleye or notice any bluish color walleye.

Hi, Ronald - That sounds like a beautiful fish! What was the substrate like where you caught it? I’ve had fishermen tell me that they caught tan-coloured walleyes over sandy lake bottoms, dark green walleyes in a dark green river, and that a typical walleye can turn very pale when kept in a pale-coloured live well for a length of time. All kinds of things may affect colour. It is an interesting topic and walleyes show lots of variety.

@@DrDave-Ecologic it was during the spring‘s spawn in the Sandusky River it was a gravel substrate the rest of the walleye from that location we’re regular colored. It held its golden color in the cooler.

@@ronaldyoung9430 Hey, Ronald - thanks for that info. In piecing together stories like yours, patterns are bound to emerge in what fishermen are finding throughout a wide geographical range. Much obliged!
