Estimates based on models

Preferred temperature (Ref. 115969): 2.3 - 13, mean 9.9 (based on 221 cells).

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

Bayesian length-weight: a=0.00138 (0.00084 - 0.00228), b=3.21 (3.06 - 3.36), in cm Total Length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).

Trofisk nivå (Ref. 69278): 3.1 ±0.30 se; based on food items.

Resiliens (Ref. 120179): Mellan, lägsta populationsfördubblingstid 1,4-4,4 år (Assuming tmax>3).

Fishing Vulnerability (Ref. 59153): Low to moderate vulnerability (30 of 100).
