CHUB (Leuciscus cephalus), a fish of the Cyprinid family, belonging to the same genus as the roach and dace. It is one of the largest of its family, attaining a length of 2 ft. and a weight of 5 to 7 lb. It does not avoid running waters, and is fond of insects, taking the fly readily, but its flesh, like that of the other Leucisci, is tasteless and full of bones. It is common in Great Britain and the continent of Europe. In America the name of "chub" is given to some other members of the family, and commonly to the horned dace (Semnotilus atromaculatus); well-known varieties are the river chub (Hybopsis kentuckiensis) and Columbia river chub (Mylochilus caurinus).
