Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5781 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01096 (0.00607 - 0.01980), b=3.08 (2.91 - 3.25), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref.
93245).
营养阶层 (Ref.
69278): 4.0 ±0.68 se; based on food items.
Generation time: 2.2 (1.9 - 4.6) years. Estimated as median ln(3)/K based on 13
growth studies.
回复力 (Ref.
120179): 中等的, 族群倍增时间最少 1.4 - 4.4年 (K=0.23-0.73; tmax=9).
Fishing Vulnerability (Ref.
59153): Low to moderate vulnerability (26 of 100).
