Wikipedia Abstract

The northern pikeminnow, or Columbia River dace (Ptychocheilus oregonensis) is a large member of the minnow family, Cyprinidae. Until 1999, when the American Fisheries Society officially changed the common name to pikeminnow, the four species of this genus were known as squawfish. Female northern pikeminnow reach sexual maturity at about six years, males in three to five. They can live longer than 15 years, reaching over 24 inches and eight pounds. The current world record weight for the pikeminnow, 13½ pounds, is held by Christopher Borger and Michael Ray of Edmonton, Alberta. A mature female can lay 30,000 eggs annually. Pikeminnow are voracious predators, and in the Columbia and Snake Rivers, salmon smolts comprise a large part of their diets. Their populations have flourished with the
