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=0.00851 (0.00478 - 0.01517), b=2.97 (2.82 - 3.12), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).

Trofisk nivå (Ref. 69278): 3.5 ±0.4 se; based on size and trophs of closest relatives

Resiliens (Ref. 120179): Mellan, lägsta populationsfördubblingstid 1,4-4,4 år (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100).
