Tamaño / Peso / Age

Maturity: L_m ? range ? - ? cm
Max length : 10.0 cm TL macho / no sexado; (Ref. )

A blind cave fish that recently evolved from the surface form Astyanax mexicanus. A length estimate for this species is 10 cm (Glenn Owens, pers.comm. 2009).

Life cycle and mating behavior Maturities | Reproducción | Spawnings | Egg(s) | Fecundities | Larva

Expels eggs in a more or less haphazard fashion, the substrate on which the species spawns must have crevices and pores into which the adhesive eggs can roll and be hidden so to prevent predation by its parents or other cave inhabitants.

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).

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

Resiliencia (Ref. 120179): Alto, población duplicada en un tiempo mínimo inferior a 15 meses (Preliminary K or Fecundity.).

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