Fishermen have nicknamed it УstokerФ for its dark color. Some individual specimens are as long as 50 cm. The species is widespread in the north from the area of Sovetskaya Gavan in Tatar Strait to the south of Korea. Groups of dark perch are not numerous (not more than 20 specimens in one place), this being due to their feeding habits, given that they feed on large invertebrates and fish. Now, the young of both these species form common schools to separate therefrom as they grow.
