Estimates based on models

Preferred temperature (Ref. 123201): 4.9 - 8.6, mean 6.3 °C (based on 84 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01000 (0.00495 - 0.02022), 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):  3.7   ±0.5 se; based on size and trophs of closest relatives
Resilience (Ref. 120179):  Very Low, minimum population doubling time more than 14 years (tmax=87; tm=10).
Fishing Vulnerability (Ref. 59153):  Low to moderate vulnerability (31 of 100).
Price category (Ref. 80766):   Medium.
