Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5001 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00676 (0.00446 - 0.01025), b=3.06 (2.94 - 3.18), in cm total length, based on LWR estimates for this species & Genus-body shape (Ref. 93245).

Niveau trophique (Ref. 69278): 3.9 ±0.63 se; based on food items.

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 (42 of 100).
