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=0.01000 (0.00534 - 0.01873), b=2.95 (2.79 - 3.11), in cm Total Length, based on LWR estimates for this species & Genus-body shape (Ref. 93245).

Trofisk nivå (Ref. 69278): 3.6 ±0.50 se; based on food items.

Resiliens (Ref. 120179): Låg, lägsta populationsfördubblingstid 4,5-14 år (tmax=12).

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