Description

The white sturgeon is one of North America's largest freshwater fishes and occurs along the Pacific coast from Alaska to California. The species has an elongate, grey body with rows of bony plates (scutes) and bears barbels beneath the pointed snout above a downward-facing, protrusible mouth. Exceptional individuals reach six metres and over a hundred years of age. The fish is anadromous: it lives largely in the sea and coastal waters and migrates far up rivers to spawn. It feeds on fishes and bottom animals. The species yields meat and caviar.
