Short description Morphology | Morphometrics

Dorsal spines (total): 0; Dorsal soft rays (total): 9-11; Anal spines: 0; Anal soft rays: 10 - 16. Body elongate, moderately compressed laterally. Head relatively long, snout narrow, elongate; mouth terminal, lower jaw usually equal to upper jaw but may be longer or shorter. Overall coloration silvery with pink iridescence. Pale blue or green on back, becoming blue-green on the sides. Ventral surface silvery white. Pigmentation on premaxillae and on top of the head. Fins mainly clear or white, translucent, with lightly scattered pigmentation, pelvic fins immaculate.

Formerly commercial important, but now extinct (Ref 12269).

Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00490 (0.00263 - 0.00913), b=3.19 (3.03 - 3.35), in cm Total Length, based on LWR estimates for this species & Genus-body shape (Ref. 93245).

Trophic Level (Ref. 69278): 3.3 ±0.3 se; Based on size and trophs of closest relatives

Resilience (Ref. 69278): Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).

Vulnerability (Ref. 59153): Moderate vulnerability (38 of 100) .
