Chub

(Squalius cephalus)

Chub is a cyprinid fish that is widespread throughout central and southern Europe. It is indigenous to England but, until 2004, had not been formally recorded in Ireland. It is a species that inhabits rivers with a moderate flow, but can also be found in lakes. It was probably intentionally introduced to Ireland by anglers. Chub feed on aquatic plants and invertebrates when young but, as they mature, they feed more selectively on larger prey items, including young fish. They could result in an imbalance among our native fish communities if they establish large populations.
