Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 10; Dorsal soft rays (total): 10; Anal spines: 3; Anal soft rays: 10.

Inhabits offshore reefs (Ref. 9710), trawling grounds of the continental shelves and offshore rocky bottoms (Ref. 30573). Juveniles inshore on muddy substrates (Ref. 48635). Solitary or in small groups (Ref. 90102). Feeds mostly on bottom invertebrates and small fishes (Ref. 30573). Potential commercial fish if sufficient stocks can be located (Ref. 9775). Marketed fresh (Ref. 9775); sometimes with a strong and unpleasant flavor (Ref. 11888).

Estimates based on models

Preferred temperature (Ref. 123201): 21.6 - 28.3, mean 26.8 °C (based on 971 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5010 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01905 (0.01114 - 0.03260), b=2.89 (2.74 - 3.04), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).

Trophic level (Ref. 69278): 3.8 ±0.0 se; based on diet studies.

Generation time: 4.8 ( na - na) years. Estimated as median ln(3)/K based on 1 growth studies.

Resilience (Ref. 120179): Medium, minimum population doubling time 1.4 - 4.4 years (K=0.23).

Fishing Vulnerability (Ref. 59153): Moderate vulnerability (42 of 100).

Price category (Ref. 80766): High.

Nutrients (Ref. 124155): Calcium = 24.1 [12.4, 44.5] mg/100g; Iron = 0.444 [0.237, 0.745] mg/100g; Protein = 19.7 [17.7, 21.7] %; Omega3 = 0.133 [0.079, 0.191] g/100g; Selenium = 49.7 [31.1, 84.0] μg/100g; VitaminA = 47.9 [15.7, 134.6] μg/100g; Zinc = 0.876 [0.633, 1.196] mg/100g (wet weight);
