About

The roach is a small to medium-sized fish. It is a member of the carp family and has the typical carp shape. It is found in large ponds, lakes and slow-flowing rivers. One of the most common fish in lakes, roach often gather in large shoals in shaded areas. They are omnivorous, feeding on invertebrates, fish eggs, plants and seeds. Roach spawn in April and June, sticking their eggs to rocks and plants; the newly hatched fish stay attached to the vegetation until they have eaten their yolk sac.

How to identify

The roach is a fairly deep-bodied, silvery fish, with dark, reddish-brown fins. It is deeper-bodied than both the slender chub and dace, but is very similar to the Rudd whose protruding lower lip is its defining characteristic.

Distribution

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