Short description Morphology | Morphometrics

Anal soft rays: 8. Dorsal fin usually with 8 rays; anal fin with 8 rays; 38-44 scales on back from head to dorsal fin; 65-78, usually 67-75, scales on lateral line; and 12-15 scales above lateral line (Ref. 86798).

Biology     Glossary (e.g. epibenthic)

Inhabits rocky and sandy pools and runs of small to large rivers. Usually found in clear, warm streams (Ref. 5723). Voracious minnow with pike-like habits. Small pikeminnows (less than or equal to 7 cm SL) are found in shallow water with cover and lower velocities. The microhabitat use of these juveniles is controlled by the presence of large pikeminnows which connotes intraspecific predation. The microhabitat shift is observed to be significantly influenced by the presence rather than the number of large pikeminnows in the area (Ref. 55069).

Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5625   [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), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).
Trophic level (Ref. 69278):  2.0   ±0.2 se; based on size and trophs of closest relatives
Resilience (Ref. 120179):  Very Low, minimum population doubling time more than 14 years (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Very high vulnerability (84 of 100).
Price category (Ref. 80766):   Unknown.
