Habitat and Ecology [top]

Habitat and Ecology:	Habitat: Usually in large lowland rivers and nutrient-rich lakes. Migrates to tributaries for spawning in moderate current on gravel or submerged vegetation. Biology: Juveniles gregarious, adults more solitary. Lives up to 15 years. Spawns for the first time at 5-6 years. Spawns in March-April, when temperature rises above 10°C. Females spawn only once each season. Adults often undertake long spawning migrations. Individual females spawn with several males. Males assemble at spawning grounds and follow ripe females. Females attach the sticky eggs to gravel or submerged plant material. Feeding larvae and juveniles inhabit a wide variety of shoreline habitats. They leave the shores for deeper waters when growing. Reaches up to 130 mm SL during first year. Feeds on a wide variety of aquatic and terrestrial animals and plant material. Large individuals become predominantly piscivorous. Sometimes hybridises with Aspius aspius.
Systems:	Freshwater
