Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5313   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00372 (0.00182 - 0.00758), b=3.17 (2.99 - 3.35), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trofisk nivå (Ref. 69278):  3.2   ±0.1 se; based on diet studies.
Resiliens (Ref. 120179):  Hög, lägsta populationsfördubblingstid mindre än 15 månader (tm=1; tmax=1).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100).
