Estimates based on models

Preferred temperature (Ref. 115969): 3.3 - 13, mean 4.6 (based on 398 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5630   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00102 (0.00046 - 0.00225), b=3.06 (2.88 - 3.24), in cm Total Length, based on all LWR estimates for this body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.5   ±0.42 se; based on food items.
Resilience (Ref. 120179):  Very Low, minimum population doubling time more than 14 years (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Moderate vulnerability (42 of 100).
