| Abstract: | The occurrence of hybrids between chub, Leuciscus cephalus , and roach, Rutilus rutilus , from three rivers in England is reported. The hybrids are described and illustrated, and means of identification are indicated. Chub X roach hybrids, like those between other leuciscine cyprinid species, can be positively identified by the number and form of the pharyngeal teeth. |
