Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.6250 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.02399 (0.01094 - 0.05261), b=2.99 (2.81 - 3.17), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
устойчивость к внешним воздействиям (Ref.
120179): высокий, минимальное время удвоения популяции до 15 месяцев (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
59153): Low to moderate vulnerability (29 of 100).
