Current Population Trend:Unknown
Additional data:
Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:This species is found in algal beds and rocky reefs (Kuiter 2002). It is a protogynous sex changer (Nakazono 1979, Lee et al. 1992). Reproductive season includes May and June in Korea when water temperature begins to rise according to gonadosomatic index (Lee et al. 1992)

Use and Trade [top]

Use and Trade: This species is caught as food in Japan and Korea and is considered a tasty fish. It is not known to be collected in the aquarium trade.

Threats [top]

Major Threat(s): There are no major threats known for this species, although it is taken in the local fishery in Japan and Korea as food fish.

Conservation Actions [top]

Conservation Actions: There are no species-specific conservation measures in place for this species. However, its distribution overlaps several marine protected areas within its range (Wood 2007).
