Gudgeon (Gobio fluviatilis), a small fish of the Cyprinid family. It is nearly related to the barbel, and has a small barbel or fleshy appendage at each corner of the mouth. It is the gobione of Italy, goujon of France (whence adapted in M. English as gojon), and Grässling or Gründling of Germany. Gudgeons thrive in streams and lakes, keeping to the bottom, and seldom exceeding 8 in. in length. In China and Japan there are varieties differing only slightly from the common European type.
