Overview: Deep-sea fisheries in the high seas in the North West Pacific began in the 1960s. Most of the deep-sea fishing in the high seas targeted seamount peaks along the Emperor and Hawaiian Seamount chains, with the latter feature having been mostly incorporated into the United States of America’s exclusive economic zone (EEZ) in 1977. The trawl fisheries over the Emperor Seamount were initiated by vessels from the former Union of Soviet Socialist Republics (USSR) in 1967. In 1969, Japanese trawlers began exploratory fishing operations near the Milwaukee Seamounts (Yuryaku and Kammu). The main target species were slender armourhead and alfonsino.
