Estimates based on models
Preferred temperature (Ref.
123201): 7.5 - 16.6, mean 11.4 °C (based on 142 cells).
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5078 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00089 (0.00058 - 0.00137), b=3.30 (3.17 - 3.43), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref.
93245).
Trophic level (Ref.
69278): 3.9 ±0.2 se; based on diet studies.
устойчивость к внешним воздействиям (Ref.
120179): низкий, минимальное время удвоения популяции 4.5-14 лет (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
59153): Low to moderate vulnerability (35 of 100).
