Comments: 1991 biomass of lingcod in the Strait of Gerogia was estimated to be over 95% reduced from 1951 level; as of 2001 the abundance remained at very low and stable levels since the closure of commercial fishery in 1990; recommendation was to close the fishery to all types of gear (Ref. 87983). Also Ref. 91783, 93933, 95110.

Short description

Dorsal spines (total): 24 - 27; Dorsal soft rays (total): 21-24; Anal spines: 3; Anal soft rays: 21 - 24; Vertebrae: 55 - 59. Anal spines of adults buried in flesh, third spine closely applied to first ray (Ref. 6885). Head without scales; fleshy cirrus above each eye; large mouth; maxilla reaching almost to vertical from posterior margin of eye. Jaws with small pointed teeth interspersed with large fanglike teeth (Ref. 48751).

Ranges from the intertidal to 475 m depth (Ref. 6793). Adults are found near rocks, inshore and to 427 m (Ref. 2850). Young occur on sand or mud bottom of bays and inshore areas (Ref. 2850). Both migratory and non-migratory populations exist (Ref. 6885). Adults feed mostly on other fishes but also take crustaceans, octopi and squid (Ref. 4925). Young feed on copepods and other small crustaceans (Ref. 6885). A very important sport and commercial species (Ref. 2850). The liver is rich in vitamin A (Ref. 6885). Marketed fresh and frozen; eaten steamed, fried, broiled, boiled, microwaved and baked (Ref. 9988). Has sharp teeth and gill rakers that can cut fingers if handled.

IUCN Red List Status (Ref. 115185)
