Estimates based on models

Preferred temperature (Ref. 123201): 9.7 - 18.4, mean 13.4 °C (based on 113 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.6250   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00355 (0.00171 - 0.00737), b=3.10 (2.92 - 3.28), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  4.5   ±0.62 se; based on food items.
Resilience (Ref. 120179):  Low, minimum population doubling time 4.5 - 14 years (Fec=21-22).
Fishing Vulnerability (Ref. 59153):  High to very high vulnerability (72 of 100).
