Estimates based on models

Preferred temperature (Ref. 123201): 12.4 - 15.8, mean 14.3 °C (based on 29 cells).

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

Bayesian length-weight: a=0.00263 (0.00139 - 0.00497), b=3.21 (3.04 - 3.38), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 4.5 ±0.80 se; based on food items.

Widerstandsfähigkeit (Ref. 120179): sehr niedrig, Verdopplung der Population dauert mehr als 14 Jahre. (Fec=2).

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

Preiskategorie (Ref. 80766): Medium.
