Descrição breve Chaves de identificação | Morfologia | Morfometria

Espinhos dorsais (total) : 0; Espinhos anais: 0; Raios anais moles: 12 - 15. Scutes present along back (before dorsal fin) as well as along belly. Upper jaw with median notch. Gill rakers fine and slender, about 130 to 150 in lower limb. Anal fin short, well behind last dorsal fin ray. Scales with pectinated hind border. A dark spot behind gill cover and up to 4 series of vertically oval spots along flank.

Occurs in coastal waters, forming large schools. Feeds by filtering phytoplankton (diatoms) and zooplankton (especially copepods), but will also take small fishes and crustaceans. Breeds in spring (Chile), depositing its eggs in coastal waters on sand, to which the sticky eggs cling, the larvae rising and joining the surface plankton on hatching. Marketed fresh, frozen, or canned.

Estimates based on models

Preferred temperature (Ref. 115969): 11.3 - 23, mean 20 (based on 12 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 1.0000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00724 (0.00435 - 0.01206), b=3.13 (2.98 - 3.28), in cm Total Length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).

Nível Trófico (Ref. 69278): 2.1 ±0.0 se; based on diet studies.

Resiliência (Ref. 120179): Elevada, tempo mínimo de duplicação da população menor que 15 meses (Assuming tm=1).

Fishing Vulnerability (Ref. 59153): Low vulnerability (21 of 100).

Climate Vulnerability (Ref. 125649): High vulnerability (58 of 100).

Categoria de preço (Ref. 80766): Low.
