Kurzbeschreibung Morphologie | Morphometrie

This species, a member of the orthodus species-group of Astyanax, differs from other members of the group by the following characters: differs from villwocki, superbus, gandhiae, bopiensi, boliviensis, yariguies by the absence of a dark stripe on the sides of the body (vs. dark lateral stripe present or anterior prolongation of the caudal peduncle spot extending anteriorly over the silvery lateral stripe); differs from A. orthodus in having the caudal peduncle spot extending onto the ventral and dorsal margins of the caudal peduncle, covering 4-6 horizontal scale rows (vs. covering 2-4 horizontal scale rows on the caudal peduncle) and in having an unpigmented band across the anal-fin rays in both sexes (vs.pigmentation uniform on analfin rays); differs from A. moorii in body depth > 39% SL (vs. < 39% SL), the dorsal-pectoral fin distance > 40.5% SL (vs. < 40.5% SL), maxilla length < 33.5% HL (vs. > 33.5% SH), upper jaw length < 32% HL (vs. > 47% SH) and by the number of lateral-line scales 36-41 (vs. 44-50) (Ref. 119406).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = No PD50 data [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01738 (0.00782 - 0.03863), b=3.06 (2.89 - 3.23), 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

Widerstandsfähigkeit (Ref. 120179): hoch, Verdopplung der Population dauert weniger als 15 Monate. (Preliminary K or Fecundity.).

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