Bottom trawl fishing - Dragnet fishery

Japanese: 底引網漁業 - そこびきあみぎょぎょう（英語表記）dragnet fishery

This is a type of fishing that involves sinking a fishing net (bottom trawl) to the seabed and dragging it along the sea. It ranges from coastal fishing by small fishing boats to deep-sea bottom trawl fishing by trawlers and mechanized boats. In the waters around Japan, the border is 128°30′ east longitude, and it is divided into west trawl fishing and east trawl fishing (also called offshore bottom trawl fishing, west of 153° east longitude). The west trawl fishing area is mainly the East China Sea and the Yellow Sea, while the east trawl fishing area is the East China Sea, the Pacific Ocean, the Sea of Japan, and the Sea of Okhotsk, and the fishing methods of the fishing boats are also different. The best fishing areas are those with a shallow seabed and no obstacles, but because the fishing is done indiscriminately, there are many problems with coordination with small-scale fisheries and resource conservation. From the standpoint of resource conservation, this is a licensed fishing area, and strict regulations are imposed.

Japanese:

海底に網漁具 (底引網) を沈め，引航して行う漁業。小型漁船によって沿岸で行われるものから，トロール漁船や機船による遠洋底引網漁業まで広い範囲にわたっている。日本近海では東経 128°30′を境界に以西底引網漁業と以東底引網漁業 (沖合底引網漁業ともいい，東経 153°以西) に区分される。以西は主として東シナ海，黄海を漁場とし，以東は東シナ海，太平洋，日本海，オホーツク海にわたり，漁船の操業形態も異なる。漁場としては海底がなるべく深くなく，障害物のないところが適するが，海底生物を無差別に漁獲するため，小規模な漁業との調整や資源保護上の問題が多い。資源保護の立場から許可漁業とされ，きびしい規制が課されている。
