phylum | Chordata | Walleye is a freshwater perciform fish native to most of Canada and to the northern United States. It is a North American close relative of the European pikeperch. The walleye is sometimes called the yellow walleye to distinguish it from the blue walleye, which is a subspecies that can be found in the southern Ontario and Quebec regions.

Blue walleye (invalid)
phylum | Chordata | The blue walleye(Sander vitreus glaucus), also called the blue pike, is an invalid subspecies of walleye alleged to have inhabited the Great Lakesof North America. Morphometric studies led biologists to classify the blue walleye as a separate species in 1926, although it was later downgraded to a subspecies. Listed as an endangered species by the United States in 1967, it was declared extinct in 1983.
Genetic analyses conducted in the 21st century show that blue walleye were not genetically different from yellow walleye, rendering the taxon invalid. For more information, visit the Wikipedia entry Get back to Perches |
