Crab Factory Ship (Kani Kosen) - Crab Factory Ship

Japanese: カニ工船(蟹工船) - かにこうせん

A mother ship for crab fishing in the North Pacific. It was called a crab factory ship because the crabs it caught were canned on board. Crab fishing is carried out in a fleet consisting of one mother ship, a converted second-hand cargo ship of 5,000 to 6,000 tons, two or three 90 to 100 ton independent ships, and six to nine fishing boats (Kawasaki ships) on the mother ship. When the independent ships arrive at the fishing grounds, they set crab gill nets on the seabed. After about eight to ten days, the Kawasaki ships are lowered from the mother ship, reel in the gill nets with net haulers, remove the crabs caught in them, and deliver them to the mother ship.

北洋で行われていたカニ漁業の母船。漁獲したカニを船内で缶詰に加工していたのでカニ工船とよばれた。カニ漁業は5000～6000トンの中古の貨物船を改造した母船1隻，90～100トンの独航船2～3隻および母船にのせた漁艇(川崎船)6～9隻により1船団を構成し操業する。漁場に着くと独航船はカニ刺網を海底に設置する。8～10日ほどおいて，母船からおろされた川崎船がこの刺網をネットホーラーで巻き上げ，刺網にかかったカニをはずして母船にとどける。
