Estimates based on models

Preferred temperature (Ref. 115969): 9.4 - 12.5, mean 10.5 °C (based on 10 cells).

Phylogenetic diversity index (Ref. 82805): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00309 (0.00144 - 0.00663), b=3.22 (3.05 - 3.39), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 4.0 ±0.6 se; based on size and trophs of closest relatives

Resilienza (Ref. 120179): Basso, tempo minimo di raddoppiamento della popolazione 4.5 - 14 anni (Fec assumed to be <100).

Vulnerability (Ref. 59153): High to very high vulnerability (74 of 100) .
