Maturity: L_m ? range ? - ? cm
Max length : 38.5 cm TL mâle / non sexé; (Ref. 11953)

Although most captures have been made with bottom trawls, specimens have recently been taken in midwater trawls fished close to the bottom, suggesting forays to the water column by individuals of different sizes (Ref. 11953).

Estimates based on models

Preferred temperature (Ref. 123201): 2.1 - 9.4, mean 6.3 °C (based on 41 cells).

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

Bayesian length-weight: a=0.00219 (0.00111 - 0.00431), b=3.20 (3.03 - 3.37), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Niveau trophique (Ref. 69278): 3.3 ±0.1 se; based on size and trophs of closest relatives

Résilience (Ref. 120179): Faible, temps minimum de doublement de population : 4,5 à 14 années (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Low to moderate vulnerability (29 of 100).
