Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.7500 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00380 (0.00146 - 0.00990), b=3.12 (2.89 - 3.35), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref.
93245).
Trofisk nivå (Ref.
69278): 3.1 ±0.4 se; based on size and trophs of closest relatives
Resiliens (Ref.
120179): Låg, lägsta populationsfördubblingstid 4,5-14 år (K=0.10-0.14; tmax=33).
Fishing Vulnerability (Ref.
59153): Moderate to high vulnerability (48 of 100).
