Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00692 (0.00403 - 0.01189), b=3.07 (2.92 - 3.22), in cm total length, based on LWR estimates for this species & Genus-body shape (Ref. 93245).

Trofisk nivå (Ref. 69278): 4.4 ±0.8 se; based on size and trophs of closest relatives

Resiliens (Ref. 120179): Hög, lägsta populationsfördubblingstid mindre än 15 månader (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Low vulnerability (24 of 100).
