Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01000 (0.00579 - 0.01726), b=3.01 (2.86 - 3.16), in cm total length, based on LWR estimates for this species & Genus-body shape (Ref. 93245).

Trofisk nivå (Ref. 69278): 3.0 ±0.38 se; based on food items.

Resiliens (Ref. 120179): Mellan, lägsta populationsfördubblingstid 1,4-4,4 år (tmax=10).

Fishing Vulnerability (Ref. 59153): Moderate to high vulnerability (50 of 100).
