Short description Identification keys | Morphology | Morphometrics

Distinguished from a similar species Richardsonius balteatus by having less anal rays (8-9, rarely 10), longer snout, more slender body and less slender caudal peduncle (Ref. 86798).

Biology     Glossary (e.g. epibenthic)

Occurs in margin of lakes and all types of stream habitats but usually in pools and slow runs (Ref. 86798).

Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = 0.7500   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00851 (0.00376 - 0.01926), b=3.06 (2.86 - 3.26), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  2.9   ±0.4 se; based on size and trophs of closest relatives
Resilience (Ref. 120179):  Medium, minimum population doubling time 1.4 - 4.4 years (tmax=5).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100).
