Short description Chiavi di identificazione | Morfologia | Morfometria

Spine dorsali (totale) : 3; Raggi dorsali molli (totale) : 15; Spine anali: 1; Raggi anali molli: 8; Vertebre: 28 - 29. This species is distinguished by the following characters: first gill arch with 18 rakers; eye diameter greater than width of suborbital bone; caudal peduncle depth more than twice its length; vertebrae 28-29, of them trunk 13; haemal arch of first caudal vertebra without spurs; D III,15; A I,8; ventral-fin soft rays 7; ventral fin is usually beyond vertical of posterior margin of pectoral fin insertion; anal fin begins beyond the vertical of last ray of dorsal fin (Ref. 117111).

Gonadal maturity stage II-III for of 3.1 cm SL male (Ref. 117111).

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=0.01072 (0.00442 - 0.02595), b=3.10 (2.89 - 3.31), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.2 ±0.2 se; based on size and trophs of closest relatives

Resilienza (Ref. 120179): Alto, tempo minimo di raddoppiamento della popolazione meno di 15 mesi (Preliminary K or Fecundity.).

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