Northern Pikeminnow
Ptychocheilus oregonensis
Northern pikeminnow are large native minnows of western North America, not northern pike. They have elongated bodies, large mouths, dark greenish backs and silvery undersides, without barbels. Young fish have a dark spot near the tail base. Adults eat aquatic invertebrates and small fish. Local management programs do not establish a general harvest rule: check current regulations for the exact water before fishing or retaining fish.
Lakes and moderately sized, slow-flowing streams. Young fish often school in shallow lake margins and quiet stream backwaters. Habitat suitability alone does not establish occurrence.
