Publication Abstract

A search for intrgressive hybridisation in the rudd, Scardinius erthropthalmus, the roach, Rutilus rutilus and its hybrid

D. Thompson and K.Iwadou

Rudd, roach and their hybrids from an interbreeding population at Norwich were examined electrophoretically for seven enzymes; an examination of pharyngeal teeth supplemented the data. The rudd were compared to rudd from Lake Trawsfynydd, Wales, a lake free from roach. No differences were observed between the rudd from the two localities and no evidence was found of introgression within the fish from Norwich.
