Chub and our canals
Chub are often found in large shoals at the river surface and are found in some canals.
They have a very varied diet, with their large mouths able to feed on worms, crayfish, flying insects, small fish, berries and other plant matter. With such food sources, they can grow quickly, often reaching an impressive size.
How to identify a chub
These fish are dusky silver in colour, often with a brown-bronze sheen. Chub are quite distinctive with a blunt snout, rounded body and very large mouth.
Small chub can often be confused with dace, which are smaller and more slender with duller fins. Chub also tend to have a wider mouth shape and curved dorsal and pelvic fins with a reddish tinge.
