Geographic Range [top]

Range Description:	Streams in Carpathians draining to Danube, Dniestr, Vistula and Odra. Baltic basin, especially in northern Sweden and Finland between 64 and 68°N, central Finnish lakes area, a few streams in southern Finland, Lake Ladoga and southern Lake Onega drainage, a few lakes in northern Germany (extirpated), Lake Hancza (Poland) and Skjernaa drainage (Denmark).

Population [top]

Population:	Abundant.
Population Trend:	Unknown

Habitat and Ecology [top]

Habitat and Ecology:	Habitat: Northern, and mountain and foothill streams, oligotrophic lakes. In Carpathian streams usually more upstream than C. gobio, very rarely syntopic. Biology: Lives up to six years. Spawns for the first time at 2-4 years, about 40 mm SL. Spawns in February-April, when temperature rises above 5°C. Females spawn once a year. Most individuals spawn 2-3 seasons. They lay adhesive eggs in a compact clutch on ceiling of small cavities in gravel or rock bottom. Males guard eggs until hatching. Males may guard egg clutches of several females. Nocturnal, shifts to day-activity during winter in the Arctic. Feeds on a wide variety of benthic invertebrates.
Systems:	Freshwater
