Actinopterygii (ray-finned fishes) > Perciformes
(Perch-likes) > Sparidae
Etymology: Pagrus: Greek, pagros = a fish, Dentex, sp. (Ref. 45335).
Environment / Climate / Range
Marine; demersal; oceanodromous (Ref. 51243); depth range 10 - 200 m (Ref. 41299). Subtropical; 34°N - 15°N
Length at first maturity / Size / Weight / Age
Maturity: Lm ?, range 54 - ? cm
Max length : 100.0 cm SL male/unsexed; (Ref. 559); common length : 30.0 cm TL male/unsexed; (Ref. 2115); max. published weight: 9.7 kg (Ref. 40637)
soft rays: 8. Body with many bluish dots when fresh. Shallow body, body depth 2 or more in SL. Transverse scales 6.5-7.5. All spines of dorsal fin tough and not elongated. Posterior margin of caudal fin black, lower margin white (Ref. 42199).
Northwest Pacific: northeastern part of South China Sea (Philippines excluded) northward to Japan.
Occurs from 10 to 50 m depths, often on rough grounds, but also on softer bottoms. Also inhabits reefs (Ref. 9988). Adults migrate into shallower parts of their depth range to spawn in late spring and summer; juveniles occur mainly in the shallower areas. It is a popular food fish throughout its range. It is high-priced in Japan and used in various occasions such as wedding and festival. Feeds on benthic invertebrates, including echinoderms, worms, mollusks and crustaceans; also on fishes. Marketed live, fresh and frozen; eaten steamed, pan-fried, broiled, boiled and baked (Ref. 9988). Cultivated in cages (Ref. 9988). Used in Chinese medicine (Ref. 12166).
Conflicting descriptions of the reproductive style of this species have been reported, e.g., Ref. 34228 describe this species as being a gonochorist (Ref. 28504). After clarificatory analyses on the protogynous characteristics of this species, gonochorism is confirmed (Ref. 103751).
