长江江豚迁地保护需要注意的几个问题

Beware of Several Problems in Ex-situ Protection of Yangtze Finless Porpoise

迁地保护是保护生物学的重要手段之一,把小型鲸类从长江干流迁入故道,是中国在世界上首创的保护措施.本文回顾了30年来长江江豚(Neophocaena asiaeorientalis)的迁地保护历史,结合已有的研究成果和实践经验,对半自然水域中的水文环境、食物资源和日常管理的共性问题进行讨论与分析.这些建议旨在引起管理部门的重视,加强科学研究,确保迁地保护更好的发展.

Ex-situ conservation is one of the most important measures in biological conservation.The ex-situ conservation measure of moving small cetacean from main stream of the Yangtze River to its oxbow was first explored by chinese scientists and has been proved effective.This study reviewed the process of small cetacean over the past 30 years and analyzed the common problems,such as hydrodynamics environment,food resources and routine management.Recommendations were put forward according to the results.The study hope that these recommendations can be seriously considered by managers and scientific research can be strengthened to ensure sustainable development of small cetacean ex-situ conservation.
