Short description

Dorsal spines (total): 0; Dorsal soft rays (total): 24-28; Anal soft rays: 33 - 39. Dorsal fins widely spaced, interspace between second and third fins longer than base length of first dorsal fin. Lateral line continuous over whole body. Color is blue-gray dorsally, grading to white ventrally. Sometimes with a small black blotch at the base of the pectoral fin.

Found over the continental slope and shelf to more than 1000 m, but more common at 300-400 m. Feeds mostly on small crustaceans but large individuals also prey on small fish and cephalopods. Makes daily vertical migrations: surface waters at night and near the bottom during the day. Sold fresh and frozen, and also processed as oil and fishmeal (Ref. 1371).

Trophic Level (Ref. 69278)
4.1 ±0.3 se; Based on diet studies.

Resilience (Ref. 69278)
Medium, minimum population doubling time 1.4 - 4.4 years (K=0.18-0.22; tm=1-5; tmax=20; Fec=6000)

Vulnerability (Ref. 59153)
Low to moderate vulnerability (33 of 100)
