Estimates based on models

Preferred temperature (Ref. 123201): 7.1 - 11.3, mean 8.5 °C (based on 22 cells).

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

Bayesian length-weight: a=0.01445 (0.00647 - 0.03228), b=3.05 (2.85 - 3.25), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.3 ±0.4 se; based on size and trophs of closest relatives

Widerstandsfähigkeit (Ref. 120179): mittel, Verdopplung der Population dauert 1,4 - 4,4 Jahre. (Assuming tmax>3).

Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100).
