Descrição breve Chaves de identificação | Morfologia | Morfometria

Espinhos dorsais (total) : 11 - 13; Raios dorsais moles (total) : 10 - 12; Espinhos anais: 0; Raios anais moles: 11 - 13; Vértebras: 31. Mouth relatively small, upper jaw reaching about to middle of eye. Pectoral fins stout. Interpelvic process short and single. No prominent anterior corselet present. Swim bladder present. Vertebrae 14 precaudal plus 17 caudal, total 31 as in the mackerels (Scomber and Rastrelliger).

Estimates based on models

Preferred temperature (Ref. 115969): 22.6 - 27.8, mean 26.1 (based on 108 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.7500 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00955 (0.00464 - 0.01966), b=3.05 (2.88 - 3.22), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Nível Trófico (Ref. 69278): 4.5 ±0.80 se; based on food items.

Resiliência (Ref. 120179): Médio, tempo mínimo de duplicação da população 1,4 - 4,4 anos (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): High to very high vulnerability (75 of 100).

Categoria de preço (Ref. 80766): Very high.
