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=0.00389 (0.00180 - 0.00842), b=3.12 (2.94 - 3.30), in cm Total Length, based on all LWR estimates for this body shape (Ref. 93245).

Trofisk nivå (Ref. 69278): 3.9 ±0.6 se; based on size and trophs of closest relatives

Resiliens (Ref. 120179): Låg, lägsta populationsfördubblingstid 4,5-14 år (Preliminary low fecundity).

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