Walleye vs Yellow Perch

The check that settles it

Perch has bold dark vertical bars and no canine teeth, and rarely exceeds a pound.

Why this matters beyond curiosity

  • Look-alike species often carry different limits. Walleye and sauger, black and white crappie, pike and muskie, blue and channel catfish — each pair can have different sizes, seasons and daily limits in the same water.
  • Check it before the fish goes in the livewell. Most of the tests on this site take seconds and are far easier on a fish you are still holding.
  • If you cannot tell, release it. That is the answer that is never wrong, and it is the one a warden will not argue with.
  • Regulations are set by your state or province and change annually. This site identifies fish; it does not tell you the rules. Check the current regulations for the water you are on.

Walleye and sauger frequently have different limits, and their hybrid — the saugeye — is stocked in many waters and is often regulated as one or the other. Check your state.

Confirming a walleye

  • White tip on the lower lobe of the tail. Sauger lacks this.
  • A dark blotch at the rear base of the spiny dorsal fin, but no rows of spots on the fin membrane.
  • Large glassy eyes that reflect a torch beam.
  • Two completely separate dorsal fins and obvious canine teeth.

Confirming a yellow perch

  • Six to eight bold dark vertical bars on a yellow-gold body.
  • Orange or reddish pelvic and anal fins.
  • Two separate dorsal fins but no canine teeth.
  • Rarely exceeds a pound.
