Factory ship From Wikipedia, the free encyclopedia For the novel by Takiji Kobayashi sometimes translated as "The Factory Ship", see Kanikōsen.. The German factory ship Kiel NC 105 .. AA factory ship, also known as a fish processing vessel, is a large ocean-going vessel with extensive onboard facilities for processingaand freezing caught fish.

These vessels sailed into remote waters and processed the whale oil on board, discarding the carcass. Later whalers converted the entire whale into usable products. The efficiency of these ships and the predation they carried out on whales contributed greatly to the animals' precipitous decline. Contemporary factory ships are automated and enlarged versions of these earlier whalers. Their use for fishing has grown dramatically. For a while, Russia,Japan and Korea operated huge fishing fleets centred on factory ships, though in recent times this use has been declining. On the other hand, the use of factory ships by the United States has increased. Some factory ships can also function as mother ships. The basic idea of a mother ship is that it can carry small fishing boats that return to the mother ship with their catch. But the idea extends to include factory trawlers supporting a fleet of smaller catching vessels that are not carried on board. They serve as the main ship in a fleet operating in waters a great distance from their home ports. Types[edit] Fish processing ships consist of various types, including freezer trawlers, longline factory vessels, purse seine freezer vessels, stern trawlers and squid jiggers. Factory stern trawler [edit] The Polish factory trawler Wiesbaden See also: Fishing trawler A factory stern trawler is a large stern trawler which has additional onboard processing facilities and can stay at sea for days or weeks at a time. A stern trawler tows a fishing trawl net and hauls the catch up a stern ramp. These can be either demersal (weighted bottom trawling); pelagic (mid-water trawling); or pair trawling, where two vessels about 500 metres apart together pull one huge net with a mouth circumference of 900 meters. Freezer trawler [edit] A freezer trawler fully processes the catch on board to customers’ specifications, into frozen-at-sea fillet, block or head and gutted form. Factory freezer trawlers can run to 60 to 70 meters in length and go to sea for six weeks at a time with a crew of over 35 people. They process fish into fillets within hours of being caught. Onboard fishmeal plants process the waste product so everything is utilized.

Many states offer subsidies to their fishing fleets, which is unsustainable in the long term. According to Oceana, the global fishing fleet is currently up to 250 percent larger than it needs to be to catch what the oceans can sustainably produce. [10].
