Estimates based on models

Preferred temperature (Ref. 123201): 1.8 - 3.1, mean 2.5 °C (based on 15 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5312   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00589 (0.00347 - 0.00998), b=3.25 (3.10 - 3.40), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).
Trophic level (Ref. 69278):  3.3   ±0.3 se; based on size and trophs of closest relatives
Resilience (Ref. 120179):  Medium, minimum population doubling time 1.4 - 4.4 years (Fec = 41,650-86580).
Fishing Vulnerability (Ref. 59153):  Low to moderate vulnerability (33 of 100).
Climate Vulnerability (Ref. 125649):  High to very high vulnerability (70 of 100).
