Issue
This species is placed in the genus EpinephelusBloch, 1793 in Eschmeyer (CofF ver. May 2011: Ref. 86870) as the placement of this species is uncertain in Craig et al. (2007: Ref. 83414).

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

Marine; reef-associated; non-migratory; depth range 5 - 30 m (Ref. 5222). Tropical; 40°N - 24°N, 121°E - 142°E (Ref. 5222)

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

Northwest Pacific: known with certainty only from Japan, Korea, and China. Reports from other areas appear to be based on misidentifications of Epinephelus octofasciatus.

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: buff body with 7-8 dark bars; 3 pale interspaces below soft dorsal fin; last dark bar covers most of caudal peduncle and extends to the base of the last 2-3 dorsal fin rays; blackish brown pelvic fin rays; median fins blackish brown distally with narrow pale margin; dark maxillary streak usually hidden by maxilla; pale gill rakers and gill arches, without minute melanophores; depth of body contained 2.5-3.1 times in SL; head length 2.4-2.6 times in SL; distinctly convex interorbital area, convex dorsal head profile; diameter of posterior nostrils of adults 3-4 times bigger than anterior nostrils; angular preopercle, with enlarged serrae at angle; 1-2 small spines anterior to angle at lower edge of preopercle; serrate or smooth lower edge of subopercle and rear edge of interopercle, convex upper edge of operculum; maxilla reaches to below rear half of eye, distinct step on lower edge of maxilla; 2 rows of teeth on midlateral part of lower jaw (Ref. 89707).

Biology     Glossary (e.g. epibenthic)

Occurs near shore, including semi-enclosed sea areas in rocky reefs in shallow waters (Ref. 11230). Feeds on fishes and crustaceans (Ref. 89707). Commercially cultured in Japan.

Estimates based on models

Preferred temperature (Ref. 123201): 15.9 - 24.1, mean 20.3 °C (based on 175 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5001   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00977 (0.00522 - 0.01830), b=3.05 (2.89 - 3.21), in cm total length, based on LWR estimates for this species & Genus-body shape (Ref. 93245).
Trophic level (Ref. 69278):  4.0   ±0.66 se; based on food items.
Resilience (Ref. 120179):  Very Low, minimum population doubling time more than 14 years (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Very high vulnerability (90 of 100).
