Estimates based on models

Preferred temperature (Ref. 123201): 10.7 - 19, mean 12.8 °C (based on 115 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.6250 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01905 (0.00827 - 0.04391), b=2.97 (2.77 - 3.17), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.5 ±0.50 se; based on food items.

Widerstandsfähigkeit (Ref. 120179): mittel, Verdopplung der Population dauert 1,4 - 4,4 Jahre. (tm=1; tmax=6).

Fishing Vulnerability (Ref. 59153): Low vulnerability (20 of 100).

Preiskategorie (Ref. 80766): Unknown.
