Summary

Description

Sebastes marinus is a large, robust member of the scorpionfish family that may reach up to 1 m in length although is usually about half that size. Like similar species it has relatively large and tall fins including an almost truncate tail fin, rounded anal, pectoral and pelvic fins, and a continuous dorsal fin. The dorsal fin is split into two parts, the first with 14-16 strong spines at the front and as many rays at the back. The anal fin has 3 spines and about 8 soft rays. It is bright red with a dusky area behind the opercle.

Recorded distribution in Britain and Ireland

Found off the coasts of Scotland and north-east England.

Habitat

The ocean perch is a pelagic species usually found at depths over 100 m. Juveniles may be found in shallower, inshore waters.

Identifying features

  • Up to 1 m in length.
  • Dorsal fin with 14-16 strong spines at the front and as many soft rays at the back.
  • Anal fin with 3 spines and about 8 soft rays.
  • Bright red colouration with dusky area behind the opercle.
  • Lower preopercular spine is directed downward and slightly backward.
  • More than 55 oblique scale rows below the lateral line.

Additional information

The ocean perch, also known as the golden redfish, can be distinguished from the small redfish Sebastes viviparous by its larger size but also by not having several large dark lateral bands like those of Sebastes viviparous.
