Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5001   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00759 (0.00494 - 0.01165), b=3.00 (2.87 - 3.13), in cm Total Length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).
Trofisk nivå (Ref. 69278):  4.2   ±0.8 se; based on size and trophs of closest relatives
Resiliens (Ref. 120179):  Mycket låg, lägsta populationsfördubblingstid mer än 14 år (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  High to very high vulnerability (72 of 100).
