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=0.00676 (0.00300 - 0.01523), b=3.17 (2.98 - 3.36), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
營養階層 (Ref.
69278): 3.3 ±0.4 se; based on size and trophs of closest relatives
Generation time: 6.1 ( na - na) years. Estimated as median ln(3)/K based on 1
growth studies.
回復力 (Ref.
120179): 中等的, 族群倍增時間最少 1.4 - 4.4年 (K=0.18; tmax=5).
Fishing Vulnerability (Ref.
59153): Moderate vulnerability (39 of 100).
