Short description
Morfologi | Morfometri
Mjukstrålar i ryggfenan (totalt): 78-87; Taggstrålar i analfenan 2; Mjukstrålar i analfenan: 41 - 50; Ryggkotor: 84 - 93. Upper head profile slightly convex, rising gently from snout to dorsal-fin origin. Orbits nearly touching dorsal profile; interorbital space slightly concave. Pelvic fins reduced to 1 scale-like spine and 1 - 2 tiny rays. Pyloric caeca 16 - 18. Color of body is black or brown with a silvery shine along the abdomen.
Benthopelagic on the continental shelf and slope, up to a depth of 400 m or more; generally found over sandy bottoms at a depth between 100 and 250 m (Ref. 9351). During cold season, it is often seen near the surface at nights when the moon is full (Ref. 9351). May also be encountered in surge zones and sometimes observed to be beached in large numbers by the shore (Ref. 9351). A schooling species which feeds on cephalopods, euphausiids and small fishes, including Engraulis mordax and juvenile Merluccius productus. Marketed fresh and frozen (Ref. 9351). Excellent food fish, also processed into fish meal and oil (Ref. 9351).
