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=0.00603 (0.00509 - 0.00714), b=3.13 (3.09 - 3.17), in cm total length, based on LWR estimates for this species (Ref. 93245).
Niveau trophique (Ref. 69278):  3.3   ±0.4 se; based on size and trophs of closest relatives
Résilience (Ref. 120179):  Milieu, temps minimum de doublement de population : 1,4 à 4,4 années (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100).
