Northwest Pacific: southern China, Taiwan, East China Sea, Korea, and southern Japan (Kyushu to about 38°N on both coasts of Honshu). Reported specimen from Viet Nam may be Epinephelus fasciatomaculosus and records from the Philippines and India are unsubstantiated.

Biology     Glossary (e.g. epibenthic)

Rock-reef species inhabiting depths to at least 55 m. Juveniles are often found shallower than 10 m (Ref. 089707). A highly prized food fish usually caught by hand-lining over rock strata. Found in Hong Kong live fish markets (Ref. 27253).

Estimates of some properties based on empirical models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01820 (0.01073 - 0.03085), b=3.09 (2.94 - 3.24), based on LWR estimates for species & Genus-BS (Ref. 93245).
Trophic Level (Ref. 69278):  4.0   ±0.65 se; Based on food items.
Resilience (Ref. 69278):  Medium, minimum population doubling time 1.4 - 4.4 years (Assuming tm=2).
Vulnerability (Ref. 59153):  Moderate to high vulnerability (46 of 100) .
Price category (Ref. 80766):   Very high.
