Short description
Chiavi di identificazione | Morfologia | Morfometria
Spine dorsali (totale) : 10 - 17; Spine anali: 0; Raggi anali molli: 16 - 22; Vertebre: 41 - 45. Silvery-white with black melanophores surrounding each scale on the dorsal two-thirds of the body. The dorsal half of the body is almost translucent.
Usually occur in large schools near surface in open water, over dark sandy bottom (Ref. 35360). Well adapted to a life of heavy predation (Ref. 35360). Frequent skipping over the water surface is observed apparently in avoidance of predators (Ref. 35360).
Based on otolith data, these species spawn after their first winter and that only a small segment of the population lives through the second winter (Ref. 35360).

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5039 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01122 (0.00514 - 0.02450), b=3.04 (2.87 - 3.21), in cm total length, based on all LWR estimates for this body shape (Ref.
93245).
Trophic level (Ref.
69278): 3.1 ±0.41 se; based on food items.
Generation time: 1.1 ( na - na) years. Estimated as median ln(3)/K based on 2
growth studies.
Resilienza (Ref.
120179): Alto, tempo minimo di raddoppiamento della popolazione meno di 15 mesi (K=1.04-1.36; tmax=3).
Fishing Vulnerability (Ref.
59153): Low vulnerability (10 of 100).
