Estimates based on models

Preferred temperature (Ref. 123201): 3.5 - 9.1, mean 5.3 °C (based on 733 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 1.0000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00309 (0.00121 - 0.00790), b=3.12 (2.90 - 3.34), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.5   ±0.4 se; based on size and trophs of closest relatives
Widerstandsfähigkeit (Ref. 120179):  mittel, Verdopplung der Population dauert 1,4 - 4,4 Jahre. (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (25 of 100).
