Estimates based on models

Preferred temperature (Ref. 123201): 12.4 - 23.5, mean 17.8 °C (based on 262 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.7500   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.02239 (0.00864 - 0.05802), b=2.98 (2.75 - 3.21), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.7   ±0.1 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 (10 of 100). 🛈
