Description

The Pacific ocean perch is a rockfish (Sebastidae) from the northern Pacific. The species grows to about 50 cm and has an elongate, bright-red body with a large, spiny head. It is abundant in deeper water well offshore; young fish are pelagic up to about three years. It grows slowly and can live long. It is viviparous, with planktonic larvae. As a bottom predator it feeds on crustaceans and small fishes. It is an important commercial species. The dorsal, pelvic and anal fin spines are venomous and give a painful puncture wound.
