Mighty predator

pikeminnow

The Sacramento pikeminnow, Ptychocheilus grandis, is a pike-like cyprinid most often found in low to mid-elevation streams and rivers of the Sacramento-San Joaquin basin and other northern California drainages. Juveniles like this fish recently captured are insectivorous but quickly become piscivorous as adults. They are most often found with other native fish and rarely in highly polluted water or in lakes with centrarchids (e.g. crappie, bluegill, largemouth bass).
