Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5312 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00245 (0.00114 - 0.00526), b=3.13 (2.95 - 3.31), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Trophic level (Ref.
69278): 3.7 ±0.2 se; based on size and trophs of closest relatives
устойчивость к внешним воздействиям (Ref.
120179): низкий, минимальное время удвоения популяции 4.5-14 лет (Fec assumed to be <100).
Fishing Vulnerability (Ref.
59153): High vulnerability (61 of 100).
