Short description Claves de identificación | Morfología | Morfometría

Differs from congeners by the presence of a pronounced occipital hump, regardless of size, sexual maturity or sex; shorter predorsal length; more elongate terminal dorsal-fin spine; and shorter snout (Ref. 53256).

The largest specimen caught was in the immature stage (Ref. 53256).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.6250 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01995 (0.00906 - 0.04395), b=3.01 (2.83 - 3.19), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).

Nivel trófico (Ref. 69278): 3.3 ±0.5 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).
