Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5005 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00447 (0.00172 - 0.01163), b=3.10 (2.87 - 3.33), 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): Mycket låg, lägsta populationsfördubblingstid mer än 14 år (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Very high vulnerability (78 of 100).
