freezer trawler

A freezer trawler is a type of fishing vessel designed to drag trawl nets through the water or along the seabed to catch fish. These vessels are often large and powerful, equipped with engines and deck machinery for operating the nets. The defining characteristic of a freezer trawler is its onboard capability to preserve the catch by freezing it. Some freezer trawlers may also gut and sort the fish before freezing, though extensive processing is typically done after the fish are landed. Modern trawlers can function as floating factories, cleaning and freezing fish at sea. Steel is the most common material for constructing larger freezer trawlers.12
