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.

Population [top]

There is very little population information for Epinephelus caninus, but it is known to be rare in the Canary Islands.

Fisheries-independent data
Fishery-independent survey at protected and unprotected areas in the Mediterranean indicated that it is now rare. The highest abundance observed was 0.2 individual per 250 m² (Charton et al. 2000).
Current Population Trend:Unknown
Additional data:
Population severely fragmented:No

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).

Feeds on fishes and invertebrates.

A single specimen from Majorca was aged at 75 years old; 164 cm TL; 67 kg (Morales-Nin, Bauza and Grau 2005).

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.
