Estimates based on models

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): 2.0 ±0.00 se; based on food items.

Generation time: 19.2 ( na - na) years. Estimated as median ln(3)/K based on 1 growth studies.

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 (86 of 100).

Catégorie de prix (Ref. 80766): Unknown.
