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.

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.

Threats [top]

Major Threat(s): Locally threatened by damming in headwaters and pollution.

Errata [top]

Errata reason: When the 2010 assessment of this species was published in 2011, a 2013 citation reference was accidentally attached to the account and hence the previous version of the assessment showed it as being published in 2013 when it should have been 2011. The error is corrected here and is therefore given a 2016 citation date; the 2011 reference that should have been used in the citation is under the References.
