Short description Claves de identificación | Morfología | Morfometría

Hyphessobrycon hamatus is distinguished from all species of the genus, except H. socolofi Weitzman and H. erythrostigma (Fowler), by the presence of small bony hooks on the dorsal, anal, pelvic, and pectoral fins of males. The new species differs from H. socolofi and H. erythrostigma in the lower number of anal-fin rays (iii-v, 16-18, average=17, n=28) versus (iv, 28-30 and iv, 27-29, respectively), and by the absence of a black spot on dorsal fin versus the presence of such pigmentation.

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).

Nivel trófico (Ref. 69278): 2.9 ±0.3 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).
