Estimates based on models

Preferred temperature (Ref. 123201): 11.9 - 19.1, mean 16 °C (based on 116 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5020   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00537 (0.00260 - 0.01111), b=3.09 (2.90 - 3.28), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.3   ±0.1 se; based on diet studies.
Resilience (Ref. 120179):  Medium, minimum population doubling time 1.4 - 4.4 years (Fec=200-2,000).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100).
