Short description Chiavi di identificazione | Morfologia | Morfometria

Spine dorsali (totale) : 0; Raggi dorsali molli (totale) : 13 - 21; Spine anali: 0; Raggi anali molli: 15 - 17. The filamentous last dorsal fin ray distinguishes this species from members of any other eastern Pacific clupeoid genus. Lower gill rakers 50 to 87 in fishes over 14 cm standard length (intermediate between O. medirastre with 41 to 69 and O. libertate with 63 to 110, but neither of these occur in the Galapagos Islands).

Forms schools.

Estimates based on models

Preferred temperature (Ref. 123201): 14.5 - 23.7, mean 19.3 °C (based on 4 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5312 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00912 (0.00433 - 0.01920), b=3.04 (2.87 - 3.21), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.3 ±0.4 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 (22 of 100).

Price category (Ref. 80766): Low.

Nutrients (Ref. 124155): Calcium = 175 [97, 371] mg/100g; Iron = 1.71 [0.94, 3.00] mg/100g; Protein = 19.2 [18.0, 20.4] %; Omega3 = 0.442 [0.231, 0.860] g/100g; Selenium = 36.6 [17.6, 89.3] μg/100g; VitaminA = 43.8 [14.7, 136.6] μg/100g; Zinc = 1.05 [0.70, 1.62] mg/100g (wet weight);
