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=0.00562 (0.00251 - 0.01261), 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): 3.4 ±0.4 se; based on size and trophs of closest relatives
回复力 (Ref.
120179): 中等的, 族群倍增时间最少 1.4 - 4.4年 (tmax=4).
Fishing Vulnerability (Ref.
59153): Low vulnerability (10 of 100).
