Northern Pikeminnow
- The northern pikeminnow has a head that is somewhat flattened between the eyes.
- A long snout and a large mouth - you can usually insert 2 to 3 fingers fully into an 11-inch pikeminnow's mouth.
- One of the best ways to determine the difference between a peamouth and a pikeminnow is to compare where the corner of the mouth ends. On a pikeminnow the corner of the mouth comes back to the eye, while on the peamouth, the corner of the mouth is well before the eye.
- The barbels at the corner of the peamouth's mouth are missing on the pikeminnow, as are the dark bars on the side.
- Pikeminnow from the Columbia River are generally a bright silvery color, while those from tributaries will usually be darker and more colored.

Peamouth
- Peamouth are the species most commonly confused with the northern pikeminnow. Body shape is similar to the pikeminnow, but usually slimmer.
- The peamouth's head is more rounded than a pikeminnow.
- The species two mouths are quite different. The peamouth's round mouth is much smaller than the pikeminnows. Generally you can only fit the tip of a finger in the peamouth's mouth.
- There is red coloring around the lips, and a small barbel at each corner of the mouth.
- Also look for two dark lateral bars on the side, which turn reddish during spawning time.
- Peamouth are a native fish, they do not prey on or compete heavily with salmonid smolts. Peamouth should not be wantonly killed and discarded as trash fish.
