This fish has a thick body and a large head with a huge toothless mouth. The Chub is a wary fish. Most of its life is spent skulking in the roots of trees at the water’s edge or between thick weedbeds and it will rarely go out into open water. Chubs are omniverous but prefer to feed on small fish, crayfish and caddis larvae. They will wait under overhanging trees where they will wait for insects and berries to drop off into the water and eat those also. They are found in most river systems, and in selected Scottish rivers and in many parts of Europe.
Spawning occurs in the late spring, with the fish going to fast gravelly shallows to lay their eggs on streamer weeds and the roots of bankside trees. Like most fish, chubs are cannibalistic, eating young fish of their own kind.
Despite having no teeth, chubs have extremely strong throat teeth (pharyngeal teeth). They use these to crush and grind up tough items.
The old English name of the Chub is Chavander.
The color of the chub is bronze or slate gray on the back giving way to silver-gold sides and white underparts. The pelvic and anal fins are orange red, the dorsal and tail fins, blue gray.
