Short description Chiavi di identificazione | Morfologia | Morfometria

Spine dorsali (totale) : 1; Raggi dorsali molli (totale) : 6; Vertebre: 38 - 39. Head and body silvery, without pattern. Fins, except caudal fin, black distally, with clear basal portions; caudal fin entirely clear. Dorsal spine extending well past adipose-fin origin when adpressed. Anal fin with 5-6 simple rays, 11 branched rays. Premaxilla with 4 rows of teeth. Most similar to G. melanopterus in coloration and having the highest gill raker counts among its congeners (Ref. 40780).

Found in rivers and estuaries (Ref. 41236).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5039 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00676 (0.00307 - 0.01489), b=3.01 (2.83 - 3.19), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.3 ±0.4 se; based on size and trophs of closest relatives

Resilienza (Ref. 120179): Basso, tempo minimo di raddoppiamento della popolazione 4.5 - 14 anni (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Low vulnerability (21 of 100).
