Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00776 (0.00362 - 0.01664), b=2.98 (2.80 - 3.16), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Trophic level (Ref.
69278): 3.6 ±0.4 se; based on size and trophs of closest relatives
устойчивость к внешним воздействиям (Ref.
120179): низкий, минимальное время удвоения популяции 4.5-14 лет (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
59153): Low vulnerability (16 of 100).
