Estimates based on models

Preferred temperature (Ref. 123201): 18 - 28.3, mean 25.3 °C (based on 18 cells).

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

Bayesian length-weight: a=0.00048 (0.00025 - 0.00091), b=3.28 (3.12 - 3.44), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245).

Trofisk nivå (Ref. 69278): 4.5 ±0.8 se; based on diet studies.

Resiliens (Ref. 120179): Låg, lägsta populationsfördubblingstid 4,5-14 år (tmax=30).

Fishing Vulnerability (Ref. 59153): Very high vulnerability (90 of 100).

Price category (Ref. 80766): Medium.
