Estimates based on models

Preferred temperature (Ref. 123201): 13.6 - 20.1, mean 18.3 °C (based on 34 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00324 (0.00142 - 0.00736), b=3.17 (2.99 - 3.35), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245).

Niveau trophique (Ref. 69278): 3.3 ±0.3 se; based on size and trophs of closest relatives

Résilience (Ref. 120179): Très faible, temps minimum de doublement de population supérieur à 14 ans (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Very high vulnerability (90 of 100).

Catégorie de prix (Ref. 80766): Unknown.
