Estimates based on models

Preferred temperature (Ref. 115969): 7.3 - 12.5, mean 10 (based on 1188 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 1.0020   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01047 (0.00607 - 0.01808), b=3.00 (2.85 - 3.15), in cm Total Length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).
Nivel trófico (Ref. 69278):  4.0   ±0.60 se; based on food items.
Resiliencia (Ref. 120179):  Alto, población duplicada en un tiempo mínimo inferior a 15 meses (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (23 of 100).
