Estimates based on models
Preferred temperature (Ref.
123201): 18.5 - 20.8, mean 19.8 °C (based on 28 cells).
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5001 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00479 (0.00208 - 0.01103), b=3.08 (2.89 - 3.27), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
营养阶层 (Ref.
69278): 2.9 ±0.36 se; based on food items.
Generation time: 1.1 ( na - na) years. Estimated as median ln(3)/K based on 2
growth studies.
回复力 (Ref.
120179): 高度, 族群倍增时间少于 15个月 (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
