Biology     Glossary (e.g. epibenthic)

Inhabits runs and flowing to standing pools of headwaters, creeks, and small to medium rivers as well as lakes and ponds. Usually found over mud or sand, often near vegetation (Ref. 5723, 86798). Forms schools (Ref. 1998). Fry feed on diatoms, copepods, ostracods, and other small planktonic and demersal crustaceans (Ref. 1998). Diet changes to terrestrial and aquatic insects, algae, mollusks, fish eggs (including their own), and small fishes like other redside shiners, other minnows, and trout (Ref. 1998). Preyed upon by mergansers, loons, and mink (Ref. 1998).

Life cycle and mating behavior Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae

Adults move into spawning streams in the afternoon and evening. Spawning occurs as one female and one or two males thrash violently side by side for a few seconds. Fertilized eggs adhere to gravel and vegetation on the bottom.

Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.7500   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00813 (0.00390 - 0.01696), b=3.13 (2.96 - 3.30), based on LWR estimates for this Subfamily-body shape (Ref. 93245).
Trophic Level (Ref. 69278):  3.4   ±0.49 se; Based on food items.
Resilience (Ref. 69278):  Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153):  Low to moderate vulnerability (28 of 100) .
