Actinopterygii (ray-finned fishes) > Perciformes
(Perch-likes) > Lateolabracidae
Etymology: Lateolabrax: Greek, latos, a fish of the Nile + Greek, labrax, -akos = a fish (Dicentrarchus labrax) (Ref. 45335).
Environment / Climate / Range
Marine; freshwater; brackish; reef-associated; catadromous (Ref. 51243); depth range 5 - ? m. Subtropical, preferred 25°C (Ref. 107945); 44°N - 15°N, 106°E - 143°E
Western Pacific: Japan to the South China Sea.
Length at first maturity / Size / Weight / Age
Maturity: Lm ?, range 50 - ? cm
Max length : 102 cm TL male/unsexed; (Ref. 40637); common length : 16.1 cm SL male/unsexed; (Ref. 35840); max. published weight: 8.7 kg (Ref. 40637)
Found in moving water of inshore rocky reefs. Juveniles may ascend rivers and return to sea to spawn. Protandrous, sex change happens after maturation at age 2 (Ref. 36558). Spawning occurs during winter, in deeper rocky reefs or inshore areas. Predaceous, feeding on zooplankton at an early age and on small fish and shrimps as adults (Ref. 12497). Utilized as a food fish (Ref. 559). Family placement uncertain (Ref. 1830). Used in Chinese medicine (Ref. 12166).
Males mature at age 2 years, becoming females when older (Ref. 36558). Juveniles may ascend rivers migrating to the sea to spawn (Ref. 36558).
