Merlucciidae (Merluccid hakes)
|A bottom otter trawl is a cone-shaped net consisting of a body, normally made from two, four and sometimes more panels, closed by one or two codends and with lateral wings extending forward from the opening. A bottom trawl is kept open horizontally by two otter boards. A boat can be rigged to tow a single or two parallel trawls from the stern or from two outriggers.|
|These are trawlers on which the fish is preserved by freezing.
|Species EnvironmentPatagonian grenadier is a schooling benthopelagic species which are concentrated on the outer part of the continental shelf (depth range 30-500). Feeds mainly on fish (herring, anchovies, lantern fishes). Migrates southward in spring and summer and northward in winter. Blue grenadier appear to live usually on or near the bottom (depth range 10-1 000 m), but may occasionally move up into mid-waters. Large adult fish generally occur deeper than 400 m, while juveniles may be found in shallower water.|
