|Habitat and Ecology:||Habitat: |
Clear, well oxygenated brooks in piedmont and montane zones. 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 July-September, overwinters, and spawns in March-May, later at higher elevations, when temperatures reach 7-10°C. Spawning individuals cease their normal daylight avoidance reaction and reproduce on sunny days. Males dig shallow nests in habitats with moderate current. Dies after spawning.
|Major Threat(s):||Locally threatened by damming in headwaters and pollution.|
