Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5029 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00617 (0.00279 - 0.01364), b=3.07 (2.87 - 3.27), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Niveau trophique (Ref. 69278): 3.9 ±0.4 se; based on size and trophs of closest relatives

Generation time: 5.6 ( na - na) years. Estimated as median ln(3)/K based on 2 growth studies.

Résilience (Ref. 120179): Milieu, temps minimum de doublement de population : 1,4 à 4,4 années (K=0.20; tmax=9).

Fishing Vulnerability (Ref. 59153): Low vulnerability (13 of 100).

Catégorie de prix (Ref. 80766): Unknown.
