Estimates based on models

Preferred temperature (Ref. 123201): 0.7 - 6.3, mean 3.2 °C (based on 435 cells).

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

Bayesian length-weight: a=0.00832 (0.00544 - 0.01272), b=3.14 (3.01 - 3.27), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).

Trophic level (Ref. 69278): 3.8 ±0.2 se; based on diet studies.

Widerstandsfähigkeit (Ref. 120179): niedrig, Verdopplung der Population dauert 4,5 - 14 Jahre. (tm=6-8; tmax=9-13; K=0.08-0.21; Fec=2,00-10,000).

Fishing Vulnerability (Ref. 59153): High to very high vulnerability (68 of 100).

Preiskategorie (Ref. 80766): Very high.
