Biology     Glossary (e.g. epibenthic)

Inhabits rubble and gravel riffles (sometimes runs and pools) of fast creeks and small to medium rivers as well as rocky shores of lakes (Ref. 5723, 86798). Young up to 4 months are pelagic (Ref. 1998). Form schools (Ref. 1998). Feeds on mayflies, blackflies, and midges (Ref. 1998). Spawns over pits in loose gravel substrate (Ref. 51972). Widely used as bait in the USA (Ref. 1998). Artificially propagated in Minnesota, USA in long narrow ponds having weak water flow (Ref. 1998).

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

Ovarian development probably of the group-synchronous type. Fecundity is determinate based on release of great majority of oocytes in a given spawning season, few signs of atretic oocytes and oocyte diameter distribution points to lack of substantial production of new oocytes (Ref. 51971). Spawn on rock and gravel. Larvae benthic (Ref. 7471). According to a study (Ref. 10280), although no nest is built, a territory is established and one parent guards the nest. In Manitoba, females lay 200-1200 transparent eggs hatching in 7-10 days at 15.6°C. Young are pelagic and inhabit quiet waters inshore; pelagic stage lasts 4 months before typical bottom dwelling existence of adults commence (Ref 1998). Spawn in riffles over gravelly bottom near nest of river chub.

Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5020   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00617 (0.00306 - 0.01241), b=3.08 (2.90 - 3.26), based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic Level (Ref. 69278):  3.2   ±0.40 se; Based on food items.
Resilience (Ref. 69278):  Medium, minimum population doubling time 1.4 - 4.4 years (tm=2; tmax=5; Fec = 1,155).
Prior r = 0.47, 2 SD range = 0.21 - 1.06, log(r) = -0.76, SD log(r) = 0.4, Based on: 2 tgen, 1 tmax, 4 Fec records
Vulnerability (Ref. 59153):  Low to moderate vulnerability (35 of 100) .
