Gymnocephalus is a genus of perches native to western Eurasia. They are collectively called ruffes and resemble the common perches (Perca), but are usually smaller and have a different pattern.[1]
Species[edit]
There are currently five recognized species in this genus:[1]
- Gymnocephalus acerina (J. F. Gmelin, 1789) (Donets ruffe)
- Gymnocephalus ambriaelacus Geiger & Schliewen, 2010
- Gymnocephalus baloni Holčík & K. Hensel, 1974 (Danube ruffe)
- Gymnocephalus cernua (Linnaeus, 1758) (ruffe)
- Gymnocephalus schraetser (Linnaeus, 1758) (schraetzer)
Geographic distribution[edit]
In Europe they are found in the Caspian, Black, Baltic and North Sea basins; in Asia in the Aral Sea basin and the Arctic Ocean basin eastward to Kolyma drainage.[2]
