Estimates based on models

Preferred temperature (Ref. 123201): 3 - 4.5, mean 3.9 °C (based on 108 cells).

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

Bayesian length-weight: a=0.00355 (0.00175 - 0.00721), b=3.08 (2.90 - 3.26), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.9 ±0.4 se; based on size and trophs of closest relatives

Resilienza (Ref. 120179): Molto basso, tempo minimo di raddoppiamento della popolazione più di 14 anni (Fec assumed to be <10).

Fishing Vulnerability (Ref. 59153): Moderate vulnerability (44 of 100).
