Distribution Countries | FAO areas | Ecosystems | Occurrences | Introductions | Faunafri

North America: widespread with highly disjunct distribution in Canada and USA. The former Blue Ridge race of the Atlantic slope of the Appalchian Mountains is now recognized as a distinct species Cottus caeruleomentum.

Adults occur in rubble and gravel riffles, less often in sand-gravel runs of headwaters, creeks and small rivers. Also found in springs and their effluents and rocky shores of lakes (Ref. 1998, 10294). Feed mainly on aquatic insect larvae, but also on crustaceans, annelids, fishes, fish eggs, and plant material (Ref. 1998, 10294). Spawn in the spring (Ref. 1998). A male guards the cluster of eggs laid by different females (Ref. 1998). Neither anterolateral glandular groove nor venom gland is present (Ref. 57406).

Estimates of some properties based on empirical models

Phylogenetic diversity index (Ref. 82805): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01097 (-0.17964 - 0.20159), b=3.02687 (2.91905 - 3.13469), based on LWR estimates for this family-BS (Ref. 93245).

Trophic Level (Ref. 69278): 3.3 ±0.46 se; Based on food items.

Resilience (Ref. 69278): High, minimum population doubling time less than 15 months (tmax=2).

Vulnerability (Ref. 59153): Low to moderate vulnerability (33 of 100) .

Price category (Ref. 80766): Low.
