Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5001 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00302 (0.00141 - 0.00645), b=3.24 (3.07 - 3.41), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Trofisk nivå (Ref.
69278): 4.0 ±0.6 se; based on size and trophs of closest relatives
Resiliens (Ref.
120179): Låg, lägsta populationsfördubblingstid 4,5-14 år (Preliminary low fecundity).
Fishing Vulnerability (Ref.
