Sacramento Pikeminnow
Ptychocheilus grandisAlso known as Sacramento Squawfish, Hardhead Pike
Sacramento pikeminnows are voracious apex predators native to northern and central California waterways, capable of growing to impressive lengths over several decades. These powerful fish inhabit warm lowland rivers, clear mountain streams, and foothill reservoirs where adults hunt crustaceans and smaller fish. While historic dam construction and water diversions altered many native channels, pikeminnows remain adaptable top predators across California watershed systems.

Responsible observation
