Kurzbeschreibung Bestimmungsschlüssel | Morphologie | Morphometrie

Differs from all putative congeners by having 17-19 gill rakers on the lower limb of the first arch (vs. 11-17). Further distinguished from all congeners by the combination of the following characters: a slender body, with depth 3.7-4.2 times in SL; 14-15 branched anal-fin rays; 26-28 lateral line scales, all of which bear lateral canals; flanks with golden-bronze reflective coloration overlain by dark brown chromatophores, and dark midlateral pigmentation stripe absent (Ref. 55980).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5078 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01148 (0.00528 - 0.02495), b=3.00 (2.82 - 3.18), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

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

Widerstandsfähigkeit (Ref. 120179): hoch, Verdopplung der Population dauert weniger als 15 Monate. (Preliminary K or Fecundity.).

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