The Northern pikeminnow, Columbia River dace or colloquially Squawfish (Ptychocheilus oregonensis) is a large member of the minnow family, Leuciscidae. This predatory freshwater fish is native to northwestern North America, ranging from the Nass River basin to the Columbia River basin. A good deal of concern has been expressed regarding the impact northern pikeminnow populations may have on salmon in Columbia and Snake River impoundments.

The renaming effort was undertaken due to the word squaw being an ethnic slur for Native American women. Behavior and habitat Northern pikeminnows can live at least 11 years, reaching up to 35 in (89 cm) in total length and 15 lb (6.8 kg) in weight. Female northern pikeminnow reach sexual maturity at about six years, males in three to five. A mature female can lay 30,000 eggs annually. Pikeminnow are adept predators, and in the Columbia and Snake Rivers, salmon smolts comprise a large part of their diets. Their populations have flourished with the development of the Columbia…
