Vendace, the name given in Great Britain to a fish of the salmon family and genus coregonus (Cuv.). This fish, G. Willughbii (Jard.), or C. albula (Cuv. and Val.), is 7 to 8 in. long, delicate greenish brown above, shading into silvery below, with the lower fins bluish white; iris silvery, tinged with yellow. The mouth is very small, and without teeth except a few minute ones on the tongue; scales large; first dorsal higher than long; lower jaw the longer. The arches of the gills are furnished on the inner side with numerous long processes barbed on each side and projecting into the cavity of the mouth; those of the two sides meet and form a complete strainer, arresting the small crustaceans on which they feed until enough have been collected to be swallowed, the water at the same time flowing freely over the gills. It is highly esteemed for food, having somewhat the flavor of the smelt; it is caught only in nets; it is in best condition about Aug. 1, when it is fat and well flavored; the food consists chiefly of minute crustaceans.
