Alaska blackfish (Dallia pectoralis) – a fish of the Dallidae family, inhabiting the Chukotka water basin. The body is black and brown. The dorsal and caudal fins are fringed with a thin orange stripe which turns red during the spawning period. The length is 20 cm. The spawning is fractional from May to July. A. B. feeds mostly on wrigglers. In winter it digs into silt and often gets frozen into the ice, staying alive for a long period, but still dying in significant amounts.
