''Dissostichus eleginoides'', the Patagonian toothfish, is a species of cod icefish found in cold waters () between depths of and in the southern Atlantic, Pacific and Indian Oceans and Southern Ocean on seamounts and continental shelves around most sub-Antarctic islands. A close relative, the Antarctic toothfish (Dissostichus mawsoni), is found farther south around the edges of the Antarctic shelf; and a Marine Stewardship Council (MSC) certified fishery is active in the Ross Sea. The average weight of a commercially caught Patagonian toothfish is , depending on the fishery, with large adults occasionally exceeding . They are thought to live up to fifty years〔Collins MA, Brickle P, Brown J and Belchier M (2010) ("The Patagonian toothfish: biology, ecology and fishery" ) In: M Lesser (Ed.) ''Advances in Marine Biology'', Volume 58, pp. 229–289, Academic Press. ISBN 978-0-12-381015-1.〕 and to reach a length up to . Several commercial fisheries exist for Patagonian toothfish which are detailed below. ==Name== This species is also sold under the trade names Chilean Seabass in the USA and Canada; in Argentina, Peru and Uruguay; Legine australe in France; Mero in Japan and Spain, and Bacalao de profundidad in Chile. The name "Chilean Seabass" was invented by a fish wholesaler named Lee Lantz in 1977. He was looking for a name that would make it attractive to the American market. He considered "Pacific sea bass" and "South American sea bass" before settling on "Chilean sea bass".〔G. Bruce Knecht, ''Hooked: Pirates, Poaching, And the Perfect Fish", 2006. ISBN 1-59486-110-2. p. 9〕 In 1994, the U.S. Food and Drug Administration (FDA) accepted "Chilean Seabass" as an "alternative market name" for Patagonian toothfish,〔 and in 2013 for Antarctic toothfish. In the UK, the approved commercial designations for ''D. eleginoides'' and ''D. mawsoni'' are "icefish" and "toothfish".〔"The Fish Labelling (England) Regulations 2010", Statutory Instrument 2010 No. 420, 23 February 2010, (PDF ), came into force 6 April 2010〕 This has created some confusion as there is a genuine "icefish" (''Champsocephalus gunnari'') caught in subantarctic waters, which does not resemble toothfish in any way. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Patagonian toothfish」の詳細全文を読む スポンサード リンク
