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

Threats [top]

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