Walleye Identification
The walleye’s unique characteristics (shape, eye, fins and teeth) makes it fairly easy to identify.
Walleye
Average Size of Adults:
Commonly 12 to 28 inches and 0.5 to 8 pounds. Largest individuals may achieve 20-22 pounds in Missouri and some other states.
Identifying Characteristics:
- Slender bodied with two separate dorsal fins, large mouth and numerous teeth
- Back and sides olive brown to nearly black
- Belly and lower tip of tail fin are white.
- Distinguished from its close relative, the sauger by larger streaks (versus spots) on the first dorsal fin and a dark blotch near the base of the last few dorsal spines; lack of scales on the cheek; and a pronounced white blotch on the lower lobe of the tail fin.
Sauger
The sauger is similar to the walleye and is managed under the same regulations. They have a similar body shape and teeth and inhabit larger rivers.
Examine dorsal and tail fins to tell the difference between walleye and sauger
Spiny dorsal fin
- On the spiny dorsal fin, walleye will have a single dark blotch at the base of the last few spines.
- On the entire spiny dorsal fin, sauger have many small dark spots. However, there is no single dark blotch at the base of the last few spines.
Caudal/tail fin
- Walleye have a white patch along the lower tip.
- Sauger have no white patch along the lower tip.
