Those walleyes are definitely great eating. My son (Montana Boy) went to Door County in Wisconsin and caught over 200. The guys he went with were complaining that the fishing wasn't as good as normal.
Back in the 60's, we used to go to Lac LaRonge in northern Saskatchewan. We'd catch 6-8 pound fish as fast as you could get a big hair jig tipped with pike belly meat into the water.
