Estimates based on models

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

Bayesian length-weight: a=0.01259 (0.00609 - 0.02604), b=3.04 (2.87 - 3.21), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Niveau trophique (Ref. 69278): 3.6 ±0.50 se; based on food items.

Résilience (Ref. 120179): Faible, temps minimum de doublement de population : 4,5 à 14 années (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Moderate vulnerability (44 of 100).

Catégorie de prix (Ref. 80766): Very high.
