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=0.01047 (0.00456 - 0.02402), b=2.98 (2.80 - 3.16), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245).

Trofisk nivå (Ref. 69278): 3.9 ±0.68 se; based on food items.

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

Fishing Vulnerability (Ref. 59153): Moderate to high vulnerability (51 of 100).

Price category (Ref. 80766): Unknown.
