Abstract
In the northwestern part of the Sea of Japan, hunchback sculpin Malacocottus gibber occurs in the depth range from 160 to 940 m (maximum trawling depth) at a water temperature of 0.1–2.6°C except its atypical capture at a depth of 79 m. In the southern area (below 47°10′ N), it prefers the depth range of 300–500 m in the warm season and depths over 400 m in the cold season. In the northern area (above 47°10′ N), it tends to live at depths from 500 to 700 m throughout the year; in the cold period, its density increases in this area as a result of M. gibber approaches from smaller depths. M. gibber forms denser concentrations and begins to occur at a shallower depth under higher temperature conditions in the southern area than in the northern one. Its maximum length is 31 cm. It reaches maturation at a length of 15–18 cm; the proportion of males (in particular, adult individuals) is higher in this size group than among juveniles. On the whole, the population is dominated by females at a sex ratio of 1.5 : 1.0. M. gibber is a euryphage that feeds mainly on northern shrimp, squids of the genus Gonatopsis, polychaetes, gammarids, and euphausiids. In the spring–summer period, the average daily ration of individuals 11–25 cm long is 2.5% of body weight; no significant size-age and seasonal dynamics is observed in the feeding intensity.
