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=0.00776 (0.00343 - 0.01757), b=2.97 (2.79 - 3.15), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245).
Trofisk nivå (Ref. 69278):  2.8   ±0.26 se; based on food items.
Resiliens (Ref. 120179):  Mellan, lägsta populationsfördubblingstid 1,4-4,4 år (Assuming tm=1; Fec=50).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100).
