Estimates based on models
Preferred temperature (Ref.
123201): 15.6 - 26.5, mean 23.5 °C (based on 180 cells).
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00324 (0.00142 - 0.00736), b=3.17 (2.99 - 3.35), in cm total length, based on LWR estimates for this Genus-body shape (Ref.
93245).
营养阶层 (Ref.
69278): 3.5 ±0.37 se; based on food items.
Generation time: 12.1 ( na - na) years. Estimated as median ln(3)/K based on 1
growth studies.
回复力 (Ref.
120179): 非常低的, 最小族群倍增时间超过14 年 (Tm=9-26; Tmax=33).
Fishing Vulnerability (Ref.
