Estimates based on models

Preferred temperature (Ref. 123201): 3.3 - 4.3, mean 3.7 °C (based on 65 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01000 (0.00244 - 0.04107), b=3.04 (2.81 - 3.27), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).
Niveau trophique (Ref. 69278):  3.2   ±0.6 se; based on size and trophs of closest relatives
Résilience (Ref. 120179):  Haut, temps minimum de doublement de population inférieur à 15 mois (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100).
