Estimates based on models
Preferred temperature (Ref.
123201): 20.8 - 28.5, mean 24.7 °C (based on 42 cells).
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5020 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01259 (0.00802 - 0.01977), b=3.15 (3.02 - 3.28), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref.
93245).
Trophic level (Ref.
69278): 3.2 ±0.45 se; based on food items.
Generation time: 1.0 ( na - na) years. Estimated as median ln(3)/K based on 2
growth studies.
устойчивость к внешним воздействиям (Ref.
120179): высокий, минимальное время удвоения популяции до 15 месяцев (k >0.30).
Fishing Vulnerability (Ref.
59153): Low vulnerability (13 of 100).
