Ruff

 

(Acerina cernua), a fish of the perch family. Length, 10–15 cm (rarely reaching 30 cm); weight, 20–50 g (sometimes reaching 200 g).

The ruff is found in bodies of water in northern Asia and northern and central Europe; in the USSR its range extends from the Baltic basin to Kolyma. It lives primarily in lakes, but is also found in rivers with sluggish currents. More rarely it is found in salt water—for example, in the Aral Sea. The ruff usually lives in schools near the bottom. Sexual maturity comes at an age of two or three years. Spawning takes place from April to June on sandy or rocky land, or in floodplains on vegetation. The eggs are laid in portions with intervals of several days between individual spawnings. Fertility ranges from 4,000 to 200,000 eggs. The ruff feeds on invertebrates of the bottom and on the fry and eggs of other fish. It is caught everywhere t9gether with other fish, and should be fished intensively, since it is a competitor of more valuable commercial fishes.
