Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.7500 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01122 (0.00514 - 0.02450), b=3.04 (2.87 - 3.21), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).

Trofisk nivå (Ref. 69278): 2.0 ±0.1 se; based on size and trophs of closest relatives

Resiliens (Ref. 120179): Låg, lägsta populationsfördubblingstid 4,5-14 år (Fec=17).

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