Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = 1.0000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01148 (0.00455 - 0.02896), b=3.03 (2.81 - 3.25), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trofisk nivå (Ref. 69278):  2.4   ±0.2 se; based on size and trophs of closest relatives
Generation time: 2.0 ( na - na) years. Estimated as median ln(3)/K based on 1 growth studies.
Resiliens (Ref. 120179):  Hög, lägsta populationsfördubblingstid mindre än 15 månader (K=0.5).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (24 of 100).
