Summary ²

The Eurasian ruffe (also simply ruffe or pope), Gymnocephalus cernua, is a freshwater fish found in temperate regions of Europe and northern Asia. It has been introduced into the Great Lakes of North America, reportedly with unfortunate results. Its common names are ambiguous – "ruffe" may refer to any local member of its genus Gymnocephalus, which as a whole is natively endemic to Eurasia.
