Wikipedia Abstract

The Alaska blackfish, Dallia pectoralis, is a fish that grows to 7 in (180 mm) in length. It is elongated and cylindrical, with a dark olive-brown coloration. Four to six dark blotches run vertically along the sides, and the belly is white. The fins have reddish-brown speckles. Once thought to be an herbivore, its primary diet is midges and mosquito insect larvae. Alaska blackfish are found in swamps, ponds, lakes, and streams with vegetation for cover, in tundra and forested locations not far inland. Their range includes Alaska and the Bering Sea islands. Alaska Natives once ate these fish and fed them to their dogs, catching them in the fall and freezing them for use over winter.
