翻訳と辞書　辞書検索 [ 開発暫定版 ] スポンサード リンク Tuna Penning ： ウィキペディア英語版 Tuna Penning Tuna penning is a practice used in marine aquaculture, in which smaller tuna are caught off shore and moved back to large, in-water enclosures. The pens are typically located in the relatively shallow waters of sheltered areas, such as bays or coves. Tuna penning is primarily used for Atlantic Bluefin Tuna (ABT), a highly profitable stock for the global fish market. The tuna caught for penning are typically caught between May and July by purse-seine vessels, and then transported back to pens, where they are fattened until October–January before being frozen and shipped out. While in the pens, the tuna are fed primarily fresh fish, such as sardines, squid, and mackerel. In the past decade, tuna penning has become a large sector within the fish aquaculture industry, and takes place primarily in the Mediterranean. In 2010, ABT constituted 8% of global fish exports, the majority of which was shipped to Japan.〔 Tuna penning is regulated by the International Commission for the Conservation of Atlantic Tunas (ICCAT), and each farm is required to register both the number of tuna it has and the total capacity of the farm.〔 ==Geography== Large scale tuna penning production began in the 1980s off the coast of Canada. In the 1990s, the practice was moved over to Spain, and quickly spread through the Mediterranean. In the Mediterranean, the main producers are Italy, Malta, and Spain. Other tuna penning locations include Turkey, Croatia, Cyprus, Greece, Tunisia, and Libya. As of a 2010 census, there are over 60 tuna farms in the Mediterranean, with a total capacity of nearly 61,000 tons of tuna.〔 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「Tuna Penning」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
