The Northern pikeminnow, Columbia River dace or colloquially Squawfish (Ptychocheilus oregonensis) is a large member of the minnow family, Leuciscidae.[2] This predatory freshwater fish is native to northwestern North America, ranging from the Nass River basin to the Columbia River basin.[2] A good deal of concern has been expressed regarding the impact northern pikeminnow populations may have on salmon in Columbia and Snake River impoundments.[3]
