Estimates based on models

Preferred temperature (Ref. 123201): 4.6 - 9.5, mean 6.4 °C (based on 72 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01000 (0.00499 - 0.02004), b=3.09 (2.92 - 3.26), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.6   ±0.5 se; based on size and trophs of closest relatives
Resilience (Ref. 120179):  Low, minimum population doubling time 4.5 - 14 years (tmax=26).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (13 of 100).
