Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 1.0010 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00575 (0.00275 - 0.01206), b=3.08 (2.88 - 3.28), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref.
93245).
Trophic level (Ref.
69278): 3.3 ±0.4 se; based on size and trophs of closest relatives
Generation time: 2.0 ( na - na) years. Estimated as median ln(3)/K based on 1
growth studies.
устойчивость к внешним воздействиям (Ref.
120179): средний (среднего размера), минимальное время удвоения популяции 1.4-4.4 года (tmax = 6; Fec = 5,370).
Fishing Vulnerability (Ref.
