Korte beschrijving Determinatiesleutels | Morfologie | Morfometrie

Dorsale stekels (totaal) : 0; Anale stekels: 0; Anale zachte stralen: 43 - 48. Belly with around 26 scutes. Lower jaw not strongly projecting; hind tip of maxilla meets lower bulge of maxilla blade and is overlapped by it; teeth very small or minute. Dorsal fin well behind midpoint of body; anal fin long, its origin before dorsal fin origin. A silver band along flank.

Occurs in coastal waters and off river mouths (e.g. Río Mayo, Gulf of California) thus perhaps tolerating lowered salinities. Feeds on planktonic crustaceans. Spawns over an extended period off Costa Rica.

Estimates based on models

Preferred temperature (Ref. 123201): 23.3 - 28.6, mean 26.9 °C (based on 38 cells).

Fylogenetische diversiteitsindex (Ref. 82804): PD₅₀ = 0.7500 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00724 (0.00405 - 0.01297), b=3.14 (2.98 - 3.30), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).

Trofisch niveau (Ref. 69278): 3.8 ±0.59 se; based on food items.

Weerstandsvermogen (Ref. 120179): Hoog, minimale populatieverdubbelingstijd minder dan 15 maanden (Preliminary K or Fecundity.).

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

Prijsklasse (Ref. 80766): Low.
