Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.6250 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00708 (0.00597 - 0.00839), b=3.06 (3.01 - 3.11), in cm total length, based on LWR estimates for this species (Ref.
93245).
Trofisk nivå (Ref.
69278): 3.8 ±0.6 se; based on diet studies.
Resiliens (Ref.
120179): Låg, lägsta populationsfördubblingstid 4,5-14 år (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
59153): High to very high vulnerability (72 of 100).
Nutrients (Ref.
