Estimates based on models

Preferred temperature (Ref. 123201): 1.9 - 16.1, mean 12 °C (based on 8 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5625 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00372 (0.00160 - 0.00860), b=3.15 (2.94 - 3.36), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Niveau trophique (Ref. 69278): 3.9 ±0.6 se; based on size and trophs of closest relatives

Résilience (Ref. 120179): Faible, temps minimum de doublement de population : 4,5 à 14 années (Fec assumed to be <100).

Fishing Vulnerability (Ref. 59153): Moderate to high vulnerability (46 of 100).
