Sebastes inermis

Sebastes inermis (Japanese red seaperch, dark-banded rockfish) is a species of rockfish native to the northwestern Pacific Ocean, where it occurs off the coasts of Japan and the Korean Peninsula. This species grows to a total length of 35 cm (14 in), and the heaviest recorded specimen weighed 800 g (1.8 lb). This fish is important to both commercial fisheries and the sport-fishing industry. It is also raised to supply market demand. The Japanese seaperches are twice as expensive as European seabass. Sometimes, the Japanese red seaperch is mixed up with Japanese black seaperch (Sebastes ventricosus) and Japanese seabass.
