Korte beschrijving Determinatiesleutels | Morfologie | Morfometrie

Dorsale zachte stralen (totaal) : 10; Anale zachte stralen: 21 - 24; Wervels: 34. Astyanax macal is distinguished from other congeners in Yucatan, Peten and Belize by having the following characters: predorsal length, 50% SL or shorter (50% or longer in A. altior and A. angustifrons); least depth, 12% SL or less (12% or more in A. altior); origin of anal fin usually without overlap to last dorsal-fin ray (usually overlapping in A. baileyi); double scaly sheath in anal-fin base (vs. single); bifid nuptial tubercles in male (vs. always simple); rostral fontanel, sides convex (vs. usually straight) (Ref. 118583).

Estimates based on models

Fylogenetische diversiteitsindex (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).

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

Weerstandsvermogen (Ref. 120179): Hoog, minimale populatieverdubbelingstijd minder dan 15 maanden (Preliminary K or Fecundity.).

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