Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5001 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01413 (0.00744 - 0.02681), b=3.11 (2.95 - 3.27), in cm total length, based on LWR estimates for this species & Genus-body shape (Ref.
93245).
营养阶层 (Ref.
69278): 3.2 ±0.0 se; based on diet studies.
回复力 (Ref.
120179): 中等的, 族群倍增时间最少 1.4 - 4.4年 (Fec=1000).
Fishing Vulnerability (Ref.
59153): Low vulnerability (21 of 100).
