A medium-sized fish, the chub is a member of the carp family. It can sometimes be seen swimming near the surface of rivers and streams, often in large shoals. Omnivorous, chub feed on invertebrates, small fish, fish eggs, plants and seeds. Spawning takes place in spring and summer, during which time, the female distributes her eggs among gravel and vegetation.

What to look for

A slender fish, the chub is greenish-silver in colour with reddish, rounded fins. It is larger than the dace and has redder fins; it is more slender than the roach.

Where to find

Widespread in lowland England, but rarer in Wales and Scotland.
