Short description Identification keys | Morphology | Morphometrics

Dorsal soft rays (total): 9; Anal soft rays: 20 - 22; Vertebrae: 32 - 33. Astyanax salvatoris is distinguished from other congeners in Oaxaca by following characters: anal-fin rays 20-22 (vs. 21-26); total gill rakers, mean 17 (vs. mean 22 or more in A. finitimus); anterior fontanel sharp-tipped (vs. blunt), long (vs. shorter in A. finitimus); in dorsal view, supraoccipital short, wide-based (vs. long, narrow-based in A. aeneus); 4 maxillary teeth, 2 larger followed by 2 smaller (vs. 1-3, all about same size); epibranchial III distal segment straight (vs. curved in A. finitimus); preopercular ventral rim, convex (vs. straight in A. aeneus); and predorsal elements irregularly expanded (Ref. 118583).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01148 (0.00526 - 0.02507), b=3.08 (2.91 - 3.25), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245).

Trophic level (Ref. 69278): 2.9 ±0.4 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).
