Estimates based on models

Preferred temperature (Ref. 123201): 5.2 - 11.5, mean 7.9 °C (based on 57 cells).

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

Bayesian length-weight: a=0.00525 (0.00237 - 0.01161), b=3.15 (2.96 - 3.34), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.3 ±0.5 se; based on size and trophs of closest relatives

Widerstandsfähigkeit (Ref. 120179): hoch, Verdopplung der Population dauert weniger als 15 Monate. (Preliminary K or Fecundity.).

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