I'd like to put my 2 cents worth in here..... There are a couple of lakes
in my area where blue walleye can be caught...... whether or not they are
blue pike.... that could be another story..... but the lakes where they
occur are 1. up to 200-300 ft deep (and some huge fish show up on the sonar
at that depth.... but never caught one of whatever it is at that depth). 2.
Everywhere the blue walleye is caught, NO yellow walleye is found, period.
There is even one lake/river system separated into 3 parts by unnavigable
rapids. One section, pink walleye, another section, yellow walleye, and the
third section, blue walleye..... and guess where the deepest section is.....
yep... where the blue walleye are.
I hope that if DNA samples become available, that they become available to
check the fish up here.....
