Short description Identification keys | Morphology | Morphometrics

This species is distinguished from all other congeners except A. nigripinnis by having a wide infraorbital bar, its dorsal portion approximately so wide as orbital diameter (vs. distinctly narrower than orbit); differs from A. nigripinnis in having dorsal-fin origin posterior to anal-fin origin (vs. anterior) and a wide, nearly triangular basihyal, its width ca. 50 % basihyal length (vs. nearly rectangular, width ca. 35 % basihyal length) (Ref. 57613).

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).

Trophic level (Ref. 69278): 3.1 ±0.3 se; based on size and trophs of closest relatives

Resilience (Ref. 120179): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).

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