POPULATION MANAGEMENT OF MARINE MAMMALS AND ENVIRONMENTAL STUDY ON THEIR HABITATS

我们调查了海洋哺乳动物的分类、繁殖、生长、行为、取食栖息地以及它们被危险化学品(有机氯化合物、有机锡化合物和重金属等)污染的栖息地的环境状况。发表科技论文37篇，发表图书、报告36篇。我们还在国际和国内科学学会做了49次报告，并向公众做了28次讲座。基于这些科学结果，我们建议对海洋哺乳动物进行实际管理，其中不仅包括生活史参数的信息，还包括海洋污染的信息。我们通过主页(http：//wakame.ori.u-tokyo.ac.jp)向世界各地的公众传播这些科学信息。

We investigated taxonomy, reproduction, growth, behavior, feeding habitat of marine mammals, and environmental condition of their habitats polluted by hazardous chemicals (organochlorine compounds, organtin conpounds, and heavy metals, etc). Concerning this project, we published 37 scientific papers, and 36 articles of book and report. We also made 49 presentations in the international and domestic scientific society, and also 28 lectures to public people. Based on these scientific results, we recommended actual management of marine mammals, which involved not only information on life history parameters but also information on marine pollution. We disseminated these scientific information to the public people in the worlds by home page (http : //wakame.ori.u-tokyo.ac.jp).
