Short description Morfologi | Morfometri

Distinguished from most species of Astyanax by the vertically elongated humeral spot, slightly expanded above the lateral line to posterodorsal margin of opercle, followed by a midlateral dark stripe expanded from the humeral region to the median caudal-fin rays, maxilla with 2-5 teeth (usually 3) and anal fin with 15-18 branched rays (Ref. 56783).

Found in headwater stream with clear water, light to moderate water current and bottom consisting of stones, sand and moderate amount of vegetal debris (Ref. 56783). Feeds most frequently on microcrustaceans (Cladocera and Copepoda), insect larvae (Chironomidae), adult insects and plant fragments (Ref. 56783).

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=0.01000 (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).

Trofisk nivå (Ref. 69278): 2.9 ±0.4 se; based on size and trophs of closest relatives

Resiliens (Ref. 120179): Hög, lägsta populationsfördubblingstid mindre än 15 månader (Preliminary K or Fecundity.).

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