Estimates based on models

Preferred temperature (Ref. 123201): 2.3 - 4.2, mean 2.5 °C (based on 553 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 1.0000   [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).
Trophic level (Ref. 69278):  3.2   ±0.31 se; based on food items.
Resilience (Ref. 120179):  Medium, minimum population doubling time 1.4 - 4.4 years (Assuming tmax>3).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (13 of 100).
