Estimates based on models

Preferred temperature (Ref. 115969): 1.6 - 2.5, mean 1.8 (based on 1197 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 1.0000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00776 (0.00428 - 0.01408), b=3.04 (2.87 - 3.21), in cm Total Length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).
Trophic level (Ref. 69278):  4.2   ±0.1 se; based on diet studies.
Resilience (Ref. 120179):  High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (23 of 100).
