Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.6250 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00776 (0.00436 - 0.01383), b=3.02 (2.87 - 3.17), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).

Niveau trophique (Ref. 69278): 2.6 ±0.2 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): Low vulnerability (20 of 100).

Catégorie de prix (Ref. 80766): Unknown.
