Biology     Glossary (e.g. epibenthic)

Occurs in pools and runs of medium to large rivers. Also found in lakes. Pelagic up to 1.8 cm in length (Ref. 1998). Young feed on planktonic cladocerans, copepods, ostracods, and mites; chironomid, trichopteran and ephemeropteran larvae; and bottom ooze (Ref. 1998). Adults feed on algae, diatoms, insects, amphipods, and mollusks (Ref. 1998). May feed on salmonid eggs (Ref. 1998). Preyed upon by mergansers, osprey, eagles, and bears (Ref. 1998). Edible but not highly favored (Ref. 1998).

Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00389 (0.00180 - 0.00842), b=3.12 (2.94 - 3.30), based on all LWR estimates for this body shape (Ref. 93245).
Trophic Level (Ref. 69278):  3.1   ±0.41 se; Based on food items.
Resilience (Ref. 69278):  Low, minimum population doubling time 4.5 - 14 years (tmax=15).
Vulnerability (Ref. 59153):  Moderate to high vulnerability (46 of 100) .
Price category (Ref. 80766):   Unknown.
