Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 0; Dorsal soft rays (total): 95 - 120; Anal soft rays: 85 - 102. Pectoral fin of eyed side shorter than head. Distal part of pectoral fin blackish (Ref. 232). Large mucus pores on the blind side of the head. Uniform coloration, rough scales. Body elongated with complete straight lateral line (Ref. 35388).

Inhabits soft mud bottoms in fairly deep water (Ref. 9988). Benthic (Ref. 58426). Feeds on crustaceans, polychaetes, brittle stars (Ref. 9988) and fishes (Ref. 58426). Marketed fresh or frozen; eaten steamed, fried, microwaved and baked (Ref. 9988).

Estimates based on models

Preferred temperature (Ref. 115969): 0.6 - 11.4, mean 7 (based on 1302 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.6250 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00457 (0.00365 - 0.00573), b=3.08 (3.01 - 3.15), in cm Total Length, based on LWR estimates for this species (Ref. 93245).

Trophic level (Ref. 69278): 3.2 ±0.2 se; based on diet studies.

Resilience (Ref. 120179): Medium, minimum population doubling time 1.4 - 4.4 years (K=0.15-0.2; tmax=25).

Prior r = 0.32, 95% CL = 0.21 - 0.48, Based on 8 full stock assessments.
