Assessor/s:

Reviewer/s:

Justification:
A widespread species and abundant in Poland and Ukraine. However it is suspected to be undergoing a slow population decline with recent and on-going economic development, but not at a rate to qualify for a threatened or Near Threatened category.

European Union 27 = LC. Same rationale as above.

History:

2008	–	Least Concern (IUCN 2008)
2008	–	Least Concern
1996	–	Data Deficient

Population:	Abundant in Poland and Ukraine, but suspected to be gradually declining overall.
Population Trend:	Decreasing

Habitat and Ecology [top]

Habitat and Ecology:	Habitat: Lowland, piedmont and montane zones in clear, well oxygenated brooks. Ammocoetes in detritus-rich sands or clay sediments. Biology: Non-predatory, freshwater resident. Ammocoetes stage lasts 3.5-4.5 years. Feeds on detritus and micro-organisms, metamorphoses in September-December, overwinters and spawns in late April-early May, later at higher elevations, when temperatures reach 11-16°C. Spawning individuals cease their normal daylight avoidance reaction and reproduce on sunny days. Males dig a shallow nest in habitats with moderate current. Spawners form aggregations. Dies after spawning.
Systems:	Freshwater
