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=0.01148 (0.00455 - 0.02896), b=3.03 (2.81 - 3.25), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
營養階層 (Ref.
69278): 2.0 ±0.2 se; based on size and trophs of closest relatives
回復力 (Ref.
120179): 中等的, 族群倍增時間最少 1.4 - 4.4年 (tmax=8).
Fishing Vulnerability (Ref.
59153): Low to moderate vulnerability (33 of 100).
