Estimates based on models

Preferred temperature (Ref. 123201): 5.5 - 12.3, mean 8.2 °C (based on 236 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5625   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00263 (0.00121 - 0.00572), b=3.18 (2.99 - 3.37), 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.
Resilienza (Ref. 120179):  Basso, tempo minimo di raddoppiamento della popolazione 4.5 - 14 anni (Fec assumed to be <100).
Fishing Vulnerability (Ref. 59153):  High to very high vulnerability (69 of 100).
Price category (Ref. 80766):   Unknown.
