Estimates based on models
Preferred temperature (Ref.
123201): 14.7 - 23.2, mean 18.6 °C (based on 31 cells).
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5039 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00089 (0.00036 - 0.00223), b=2.98 (2.77 - 3.19), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Trophic level (Ref.
69278): 3.3 ±0.4 se; based on size and trophs of closest relatives
устойчивость к внешним воздействиям (Ref.
120179): высокий, минимальное время удвоения популяции до 15 месяцев (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
59153): Low vulnerability (10 of 100).
