Short description Morphology | Morphometrics

Dorsal spines (total): 11 - 12; Dorsal soft rays (total): 23-26; Anal spines: 2; Anal soft rays: 9 - 10; Vertebrae: 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

Resilience (Ref. 120179): Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Low to moderate vulnerability (30 of 100).

Price category (Ref. 80766): Medium.
