Estimates based on models

Preferred temperature (Ref. 115969): 3.6 - 8, mean 4.9 (based on 1084 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5625   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.02754 (0.01504 - 0.05042), b=2.95 (2.78 - 3.12), in cm Total Length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).
Trophic level (Ref. 69278):  3.4   ±0.2 se; based on diet studies.
Resilience (Ref. 120179):  Medium, minimum population doubling time 1.4 - 4.4 years (Assuming tmax>3).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100).
