Wikipedia Abstract

The broad whitefish (Coregonus nasus) is a freshwater whitefish species. Dark silvery in colour, and like a herring in its shape, its distinctive features include a convex head, short gill rakers, and a mild overbite. It is found in the Arctic-draining streams, lakes, and rivers of far eastern Russia and North America. Its prey includes larval insects, snails, and shellfish. It is eaten by humans and brown bears.
