本稿では,中国におけるトラフグ養殖と輸出,および日本市場の対応を考察する.その成果を,フグ流通,水産物流通の空間構造を検討する一助とする.中国の養殖業者は,高収益を得るため,高級魚であるトラフグの養殖に着手した.日本との立地条件などの違いから,異なる養殖手法が開発され,日本より低密度で大量の生産が行われている.今後は,生産拡大により生じる供給過剰への対策が必要で,中国国内でのフグ食自由化,市場形成が望まれる.今日の日本のトラフグ流通は,低価格の中国産フグが新たな構成要素として加わり,集荷地域が海外へも拡大するとともに,フグ利用・消費層が広がった.調理・提供の都合から生産するフグのサイズの目標が決まるなど,販売・消費のニーズが,流通の構造や構成要素とその活動,要素間の相互関係を規定する大きな要因となっている.また,中間魚輸入や,市場卸売業者によるフグ食文化の紹介や中間魚取引の仲介も確認された.

The purpose of this study is to examine puffer (tiger puffer, ocellated puffer) aquaculture and its exports from China and the imports and handling in Japan. This should help explain the details of puffer distribution and examine the spatial structure of fishery product distribution.<br> Producers in China began the aquaculture business of puffers in 1994. In 2000, about 1000 tons of Chinese puffers were exported to Japan. The aquaculture businesses are located in north China areas such as the Yellow Sea and Sea of Bohai. Chinese fish breeders began their business of puffer aquaculture to earn large profits since puffers are sold at high prices. Chinese puffer aquaculture has achieved mass production and low density by different methods from Japanese aquaculture, for example, the use of breeding rooms to pass the cold winters and the utilization of ponds where shrimp were previously cultured. It is necessary to take countermeasures to reduce the oversupply in the market owing to the expansion of production. Since consuming puffers is currently prohibited in China, free transactions of the sale and consumption of puffers are expected in the future as well as the establishment of domestic markets.<br> Today, low-cost puffers aquacultured in China are acknowledged as a new factor in puffer distribution. The areas that import puffers have been expanding overseas, and the users and consumers of puffers include all types of people. The target size of puffers varies depending on the size individual consumers prefer for cooking. This type of demand for selling and consuming puffers has become a major factor regulating the distribution structure, the actions of its elements and the interrelations of such elements. Cultured fish transactions, the introduction of puffers to the food culture, and the intermediations of cultured fish transactions by marketing wholesalers are also recognized.
