Uses: live export: yes;
Comments: Known from northern Namibia southward (Ref. 3200). Caught with bottom trawls (Ref. 36731). Was previously an important commercial species, but it was heavily overfished and catches now only amount to a few hundred tonnes a year (Ref. 36731). Specimens held at the MFMR. Also Ref. 5304, Ref. 27121, Ref. 27637, 54854.

Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 0; Dorsal soft rays (total): 82 - 100; Anal spines: 0; Anal soft rays: 65 - 78; Vertebrae: 55 - 57. Dorsal and anal fins continuous with caudal fin (Ref. 36731). Right pectoral fin more than half of, but shorter than head length; left pectoral fin present (Ref. 36731). Brownish with small dark specks; sometimes with bars on body (Ref. 3200).

Larvae are pelagic (Ref. 27121, Ref. 36731), while adults live close to the sea bed (Ref. 36731). Adults feed on worms, crustaceans, mollusks, and fish (Ref. 27121, Ref. 36731). Utilized as a food fish (Ref. 4931).

Estimates based on models

Preferred temperature (Ref. 115969): 9.2 - 11.9, mean 10.4 (based on 37 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.7500 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00977 (0.00466 - 0.02049), b=3.07 (2.90 - 3.24), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.5 ±0.45 se; based on food items.

Resilience (Ref. 120179): Low, minimum population doubling time 4.5 - 14 years (K=0.07).

Fishing Vulnerability (Ref. 59153): Moderate to high vulnerability (50 of 100).

Climate Vulnerability (Ref. 125649): Very high vulnerability (89 of 100).

Price category (Ref. 80766): High.
