The Don ruffe (Gymnocephalus acerina) is a freshwater fish of the family Percidae that grows up to 21 cm.
Description
The Don ruffe is a perch-like bottom fish of the family Percidae reaching about 21 cm. It resembles the common ruffe but has a longer, pointed snout; the yellow-brown body is covered with small dark spots and bears a continuous, spiny dorsal fin. The species lives in the fresh water of the Black and Azov Sea drainages, in slow to moderately flowing lower reaches of rivers such as the Don and the Dnieper. Mainly at night it searches the bottom for insect larvae, small crustaceans, worms and fish eggs. In spring it spawns on sand and gravel, where the eggs stick to the substrate. Through river works and water pollution it has declined locally, though globally it is assessed as Least Concern.
