Kurzbeschreibung Morphologie | Morphometrie

Rückenflossenstacheln (insgesamt): 2; Rückenflossenweichstrahlen (insgesamt): 9; Afterflossenstacheln 2-3; Afterflossenweichstrahlen: 18 - 21. Astyanax turmalinensis differs from the other species of the genus by the following combination of characters: presence of 20 to 24 anal fin rays; 34 to 36 scales in lateral lines; 1 or 2 teeth in the maxillary bone; greatest body depth at pelvic fin origin; caudal peduncle oval spot horizontally elongated, prolonging into median caudal fin rays, onward becoming a dark band laterally on the body, tapering anteriorly, to a point slightly anterior to middle of standard length; humeral black spot present, truncate anteriorly, usually circular posteriorly, extending anteroventrally, followed by a clear area and then subsequentely a vertically elongated dark area of loosely-assembled chromatophores. Snout slender, about the same mength as eye diameter; four teeth in the outer row of the premaxillary bone; posterior border of anal fin concave anteriorly.

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

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).
