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=0.00851 (0.00355 - 0.02043), b=2.93 (2.74 - 3.12), in cm total length, based on LWR estimates for this Genus-body shape (Ref.
93245).
Trofisk nivå (Ref.
69278): 3.3 ±0.4 se; based on size and trophs of closest relatives
Resiliens (Ref.
120179): Låg, lägsta populationsfördubblingstid 4,5-14 år (Assuming Fec < 100).
Fishing Vulnerability (Ref.
