Estimates based on models

Preferred temperature (Ref. 123201): 7.2 - 11.7, mean 10 °C (based on 32 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5001   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00479 (0.00250 - 0.00917), b=3.06 (2.89 - 3.23), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).
Trophic level (Ref. 69278):  3.5   ±0.37 se; based on food items.
Resilience (Ref. 120179):  High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (15 of 100).
Price category (Ref. 80766):   Medium.
