中文摘要：
Yangtze 无鳍的海豚(Neophocaena phocaenoides asiaeorientalis ) 当前从 Yichang 被限制到长江的中间、更低的活动范围到上海，中国，和毗连的 Poyang 和 Dongting 湖。它的人口尺寸由于人的活动的重影响在最后几十年期间显著地减少了，包括猎物种类，引起伴随的产地损失和降级的水发展工程，水污染，和有害钓鱼的齿轮和碰撞与机械化容器引起的意外死亡过度捕捞。仍然是个人的数字在 2006 对约 1800 感到不满，这被估计，每年象 5% 一样高以率正在减少的一个数字。三项保存措施 - 自从 1990 年代初，在 situ 和前 situ 保存和俘虏，繁殖被用于这只唯一的海豚的保护。七天赋和二“半天赋”保留到目前为止被建立了。自从 1996，无鳍的海豚的一个小组成功地在中国科学院的流体生物学的研究所在一台设备被扶养了；三个婴儿在 2005 年 7 月 5 日在监禁出生了， 2007 年 6 月 2 日和 2008 年 7 月 5 日。这些是在在世界上的监禁曾经出生的第一淡水鲸的。自从 1990，在长江的主要溪流抓住，或救的几组这些海豚被介绍了进 Tian'e-Zhou 半天赋储备。这些努力证明了那，不是仅仅这些动物在区域熬过的罐头，他们也是自然地并且成功地复制。超过 30 头小牛从那以后储备地出生了，与一～三出生的各个年。考虑死亡和转移，有约 30 个个人， 2007 的结束住在储备。在在 2008 年 4 月捕获的八成熟女性之中，五被证实怀孕。这个努力在世界上在鲸的种的远距离的保护代表第一次成功的尝试，并且为 Yangtze 无鳍的海豚的保存建立一个稳固的底。一堂课必须从中国河海豚(Lipotes vexillifer ) 的悲剧被拉，它已经被宣布多半绝灭。强壮、有效、适当的保护的措施必须快速被执行阻止 Yangtze 从成为第二只中国河海豚的无鳍的海豚，并且总体上节省长江的生物多样性。
英文摘要：
The Yangtze finless porpoise （Neophocaena phocaenoides asiaeorientalis） is currently limited to the middle and lower reaches of the Yangtze River from Yichang to Shanghai, China, and the adjoining Poyang and Dongting Lakes. Its population size has decreased remarkably during the last several decades due to the heavy impact of human activities, including overfishing of prey species, water development projects that cause attendant habitat loss and degradation, water pollution, and accidental deaths caused by harmful fishing gear and collisions with motorized vessels. It was estimated that the number of remaining individuals was down to approximately 1800 in 2006, a number that is decreasing at a rate as high as 5% per year. Three conservation measures - in situ and ex situ conservation and captive breeding have been applied to the protection of this unique porpoise since the early 1990s. Seven natural and two ＂semi-natural＂ reserves have so far been established. Since 1996, a small group of finless porpoises has been successfully reared in a facility at the Institute of Hydrobiology of the Chinese Academy of Sciences; three babies were born in captivity on July 5, 2005, June 2, 2007 and July 5, 2008. These are the first freshwater cetaceans ever born in captivity in the world. Several groups of these porpoises caught in the main stream of the Yangtze River, or rescued, have been introduced into the Tian＇e-Zhou Semi-natural Reserve since 1990. These efforts have proven that, not only can these animals survive in the area, they are also to reproduce naturally and successfully. More than 30 calves had been born in the reserve since then, with one to three born each year. Taking deaths and transfers into account, there were approximately 30 individuals living in the reserve as of the end of 2007. Among eight mature females captured in April 2008, five were confirmed pregnant. This effort represents the first successful attempt at off-site protection of a cetacean species in the world, and establishes a solid
