Short description Chiavi di identificazione | Morfologia | Morfometria

Spine dorsali (totale) : 11 - 12; Raggi dorsali molli (totale) : 23 - 26; Spine anali: 2; Raggi anali molli: 9 - 10; Vertebre: 25. A moderate sized Cynoscion, the largest specimen is 353 mm TL. It can be distinguished from its congeners by : a long head contained 2.8 to 3 times in SL, a large eye contained 5.1 to 5.8 times in head length (HL), a low gill raker count, a relatively high number of dorsal-fin rays (23-26), a long pectoral fin contained 1.6 in HL, a dark steel grey color on its dorsum and a black pigmented oral cavity.

Estimates based on models

Preferred temperature (Ref. 123201): 13.9 - 16, mean 15 °C (based on 3 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00832 (0.00391 - 0.01767), b=3.07 (2.90 - 3.24), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.8   ±0.6 se; based on size and trophs of closest relatives
Resilienza (Ref. 120179):  Medio, tempo minimo di raddoppiamento della popolazione 1.4 - 4.4 anni (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Low to moderate vulnerability (30 of 100).
Price category (Ref. 80766):   Medium.
