Estimates based on models

Preferred temperature (Ref. 123201): 11.1 - 11.4, mean 11.2 °C (based on 7 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5156 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01000 (0.00244 - 0.04107), b=3.04 (2.81 - 3.27), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).

Trofisk nivå (Ref. 69278): 3.5 ±0.5 se; based on size and trophs of closest relatives

Resiliens (Ref. 120179): Mellan, lägsta populationsfördubblingstid 1,4-4,4 år (Assuming tm=2-4).

Fishing Vulnerability (Ref. 59153): Low vulnerability (16 of 100).
