Short description Identification keys | Morphology | Morphometrics

Chrosomus saylori resembles C. erythrogaster but differs from this species by having S-shaped gut (vs. double-looped) and black on underside of head in breeding males (Ref. 86798).

Inhabits rocky pools of headwaters and creeks, usually along undercut banks or around large rocks (Ref. 86798).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5078 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01000 (0.00244 - 0.04107), b=3.04 (2.81 - 3.27), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).

Trophic level (Ref. 69278): 2.5 ±0.1 se; based on size and trophs of closest relatives

Resilience (Ref. 120179): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100).
