Etymology:

Environment: milieu / climate zone / depth range / distribution range Ecology

Marine; bathydemersal; depth range 150 - 300 m (Ref. 5222). Deep-water; 44°N - 39°S, 29°E - 136°W (Ref. 5222)

Distribution Countries | FAO areas | Ecosystems | Occurrences | Point map | Introductions | Faunafri

Indo-West Pacific: Somalia and South Africa to Japan, Australia and New Zealand. Except for Japan, China, and Korea, most distribution records for Epinephelus septemfasciatus are probably based on this species. Reported as Epinephelus compressus by Postel et al. (Ref. 6453).

Size / Weight / Age

Maturity: Lm ?  range ? - ? cm
Max length : 130 cm TL male/unsexed; (Ref. 4787); max. published weight: 80.0 kg (Ref. 4787); max. reported age: 43 years (Ref. 92312)

Short description Morphology | Morphometrics

Dorsal spines (total): 11; Dorsal soft rays (total): 14-15; Anal spines: 3; Anal soft rays: 9. Distinguished by the following characteristics: body buff with 8 broad dark brown bars; blackish brown pelvic fins and distal half of the soft dorsal and anal fins; faint dark band from eye to the middle opercle spine; presence of blackish maxillary streak; minute melanophores covering gill rakers and gill arches; depth of body contained 2.2-2.7 times in SL; head length 2.4-2.5 times in SL; distinctly convex interorbital area, convex dorsal head profile; angular preopercle, enlarged serrae at angle; 0-3 small spines at lower edge of preopecle anterior to angle; distinctly serrate lower edge of subopercle and rear edge of interopercle; convex upper edge of operculum; posterior nostrils 2-3 times larger than anterior nostrils; maxilla reaches to below rear half of eye (Ref. 89707).

Biology     Glossary (e.g. epibenthic)

Probably occurs in rocky reefs. Its apparent rarity may be due to its preference for relatively deep water.

Estimates based on models

Preferred temperature (Ref. 123201): 13.4 - 21.2, mean 15.7 °C (based on 136 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5001   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01349 (0.00612 - 0.02972), b=3.03 (2.86 - 3.20), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245).
Trophic level (Ref. 69278):  4.0   ±0.7 se; based on size and trophs of closest relatives
Generation time: 10.0 ( na - na) years. Estimated as median ln(3)/K based on 2 growth studies.
Resilience (Ref. 120179):  Very Low, minimum population doubling time more than 14 years (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  High to very high vulnerability (68 of 100).
Price category (Ref. 80766):   Very high.
Nutrients (Ref. 124155):  Calcium = 12.9 [6.0, 29.5] mg/100g; Iron = 0.31 [0.14, 0.67] mg/100g; Protein = 17.8 [16.0, 19.6] %; Omega3 = 0.353 [0.188, 0.660] g/100g; Selenium = 18.7 [8.2, 43.5] μg/100g; VitaminA = 8.75 [1.65, 45.73] μg/100g; Zinc = 0.27 [0.19, 0.41] mg/100g (wet weight);
