Bottom otter trawls

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.

Vessel types: Otter trawlers

These are trawlers on which the fish is preserved by freezing.

Characteristics

Species EnvironmentAtlantic halibut is a benthic species usually found on soft bottom but occasionally caught pelagically in depths ranging between 50-2 000 m. Feeds mainly on other fishes (cod, haddock, pogge, sand-eels, herring, capelin), but also takes cephalopods, large crustaceans and other bottom-living animals.
