Vendace (Coregonus vandesius), a species or variety of the large genus Coregonus (q.v.), found in rivers and lakes of Sweden, and in the Castle Loch at Lochmaben in Scotland. It is popularly said to have been introduced at Lochmaben by Queen Mary; but the statement rests on no authority. Like most of its congeners, the vendace is a palatable fish. Its food consists chiefly of minute crustaceans. It generally swims in shoals, often with a remarkable separation of the sexes. It attains a length of 6-8 inches; the outline rises quickly from the snout to the dorsal fin, and the body tapers rather suddenly at the tail; the under jaw projects a little; the tail is deeply forked, and the dorsal and ventral fins are long. The back is brown, the sides tinged with yellow, the cheeks partly white, and there is a red heart-shaped mark between the eyes. The vendace spawns in November and December, and multiplies rapidly; but it is now scarce at Lochmaben.
