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=0.00479 (0.00189 - 0.01213), b=3.13 (2.91 - 3.35), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trofisk nivå (Ref. 69278):  3.4   ±0.45 se; based on food items.
Resiliens (Ref. 120179):  Låg, lägsta populationsfördubblingstid 4,5-14 år (Assuming fec < 100).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100).
