Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5156 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00741 (0.00333 - 0.01648), b=2.97 (2.78 - 3.16), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Niveau trophique (Ref. 69278): 3.5 ±0.6 se; based on size and trophs of closest relatives

Résilience (Ref. 120179): Milieu, temps minimum de doublement de population : 1,4 à 4,4 années (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Moderate vulnerability (40 of 100).

Catégorie de prix (Ref. 80766): Unknown.
