日中バイオロギングシンポジウム報告

　　　　　　　　　　　　　　　　　　　　水産情報工学部　行動生態情報工学研究室　赤松友成

中国湖北省武漢市　2007年11月6日-8日

２００７年１１月６，７日、中国科学院水生生物研究所、東京大学海洋研究所、水産総合研究センター水産工学研究所の主催により標記シンポジウムが中国湖北省武漢市で開催されました。翌８日は、淡水に生息するイルカ（スナメリ）の研究フィールドを訪れました。発表は２２件、参加者は４０名あまりで、日本側と中国側でほぼ半々でした。

バイオロギングサイエンスは、現在急速に発達しつつある学問分野です。このシンポジウムでは、日本および中国の研究者が主導したバイオロギングに関する研究成果を発表するとともに、互いの交流を深めることを目的としました。


中国科学院水生生物研究所のWang副所長のあいさつのあと、バイオロギングサイエンスの創始者の一人である内藤先生、中国チョウザメの研究を主導しているQiwei博士、東大海洋研究所の宮崎先生らのキーノートスピーチが行われました。その後、二日間にわたって２０題あまりの講演がありました。


最終日は、湖北省の半自然保護区でスナメリ観察を行いました。ここは揚子江の三日月湖で、淡水にすむ小型鯨類の保護区に指定されています。閉鎖系で捕獲や装置の回収が容易であるため、イルカの生物ソナーに関するバイオロギング研究がここで進みました。

Japan-China biologging science symposium
JC-BLOSS　　

Biologging science is growing up quickly in Asian region. Especially in China, many biologging projects have started recently. This symposium focuses on biologging research initiated by Chinese and Japanese researchers, including tagging, telemetry, tracking, and remote monitoring of terrestrial and aquatic animals at anywhere in the world. Oral and poster slots are opened for contributed papers. Presenters review their updated works and indicate the future perspective in biologging science. Students are especially encouraged to join this symposium (see details of Student Travel Grant Program). One day trip to the research site of finless porpoises in freshwater systems will be held on 8th of November.
