Estimates based on models

Preferred temperature (Ref. 115969): 8.7 - 12.5, mean 10.4 °C (based on 514 cells).
Phylogenetic diversity index (Ref. 82805):  PD50 = 0.7520   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01259 (0.00634 - 0.02500), b=3.04 (2.86 - 3.22), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).
Trophic level (Ref. 69278):  4.0   ±0.66 se; based on food items.
Resilience (Ref. 120179):  Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153):  Moderate vulnerability (38 of 100) .
