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=0.00832 (0.00366 - 0.01891), b=3.10 (2.90 - 3.30), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
营养阶层 (Ref.
69278): 3.5 ±0.37 se; based on food items.
回复力 (Ref.
120179): 非常低的, 最小族群倍增时间超过14 年 (Assuming Fec<10).
Fishing Vulnerability (Ref.
59153): Very high vulnerability (90 of 100).
