Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00575 (0.00250 - 0.01326), b=3.07 (2.87 - 3.27), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trofisk nivå (Ref. 69278):  3.4   ±0.4 se; based on size and trophs of closest relatives
Resiliens (Ref. 120179):  Mellan, lägsta populationsfördubblingstid 1,4-4,4 år (tmax=4).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100).
