Population:	Abundant.
Population Trend:	Unknown

Habitat and Ecology [top]

Habitat and Ecology:	Habitat: From small lowland streams to large rivers. In channels, ditches, backwaters and lakes on sand bottom. Able to inhabit very degraded streams especially if siltation is a problem. In Baltic Sea at salinity up to 5 %. Biology: Females live up to five years, males up to three. Females spawn for the first time at 2-3 years, males at 1-2 years and more than 45 mm SL. Spawns in April-July, at temperatures above 18°C. Eggs are spawned in dense vegetation. Fractional spawner, producing 1-18 portions (under laboratory conditions). Larvae negatively phototactic, hiding under vegetation and in debris until beginning of exogenous feeding. Usually occurring together with hybridogenous, sperm-parasitic lineages, which have originated by hybridisation with C. elongatoides.
Systems:	Freshwater
