The common name of the Northern Squawfish has been changed to Northern Pikeminnow by the American Fisheries Society.
The Northern Pikeminnow is a large member of the minnow family native to the Pacific slope of Western North America. Formerly known as "Northern Squawfish", the name was changed to Northern Pikeminnow by the American Fisheries Society in 1998. It has a long snout with a large mouth extending back to the eye. The body is dark green or dusky green above and silvery or creamy white below, with clear fins. Northern Pikeminnow are similar in shape to the non-native walleye, but lacks the walleye's obvious teeth and spiny fin rays.
The Northern Pikeminnow of the Columbia river is not the same as the threatened Colorado Pikeminnow. They are two distinct species.
