This ugly, dark, eel-like fish, with tiny eyes, a ridiculously short dorsal fin and very long anal fin, a wide mouth with six long barbels, grows to enormous sizes in some Continental rivers, especially the Danube. It is found in a few ponds in Bedfordshire and Buckinghamshire where it was artificially introduced. It is a sluggish fish, usually hidden in the mud or under roots, and feeds on almost anything edible from fish, frogs and rats to bread. Largest angled* in Britain 37½ lbs.
