Short description Chiavi di identificazione | Morfologia | Morfometria
Diagnosis: 15-16 gill rakers on first ceratobranchial; preorbital 16.7-17.5% HL; teeth in outer rows on dentary and premaxilla of mature males small and bicuspid (Ref. 57549).
Feeds on plankton, and basied on the shape and the silvery coloration, probably lives over sand in the open water (Ref. 5595).

Estimates based on models
Phylogenetic diversity index (Ref. 82804): PD50 = 0.5156 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01000 (0.00244 - 0.04107), b=3.04 (2.81 - 3.27), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).
Trophic level (Ref. 69278): 3.4 ±0.45 se; based on food items.
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).
Nutrients (Ref. 124155): Calcium = 641 [120, 1,692] mg/100g; Iron = 4.09 [1.08, 11.81] mg/100g; Protein = 18 [17, 20] %; Omega3 = 0.448 [0.149, 1.389] g/100g; Selenium = 37.8 [15.1, 88.7] μg/100g; VitaminA = 160 [35, 546] μg/100g; Zinc = 2.77 [1.78, 4.34] mg/100g (wet weight); based on nutrient studies.
