noun    (Concise Encyclopedia)

Any of several game fishes (genus Thymallus), similar to trout, that are found in cold, clear streams of Eurasia and northern North America. Graylings are silvery purple and reach a length of about 16 in. (40 cm). They have relatively large scales, a small mouth with weak teeth, and a sail-like, brightly coloured dorsal fin. They feed primarily on insects and spawn in shallow water in the spring. Pollution of streams has reduced the numbers of this excellent food fish.
