Although widespread, Epinephelus caninus is heavily fished in some parts of its range, but there is very little population information to determine the extent of any decline. Therefore, this species is listed as Data Deficient until more information comes available. The species should be carefully monitored and re-assessed regularly.

Habitat and Ecology [top]

Habitat and Ecology: General
Epinephelus caninus is a demersal species that occurs on sandy mud bottoms 30 to 400 m. A maximum weight of 78 kg was reported by Jose Manuel, Spain (05/05).

Threats [top]

Major Threat(s): Overfishing for commercial trade is a major threat in many parts of its range, e.g., in the Mediterranean and the coast of west Africa.

Conservation Actions [top]

Conservation Actions: Epinephelus caninus occurs in protected areas in the Mediterranean, but there is no protection in its African range. Harvest management is recommended for the overfished part of its range.
