日本珊瑚礁的恶化是一个严重的环境问题。传统的陆地生态系统养护政策有时很难适用于珊瑚礁保护，因为涉及的利益攸关方很多。为了解决这一问题，日本冲绳的潜水游客开始参加潜水商店提供的旅游，将珊瑚碎片移植到退化的珊瑚礁上，这似乎是一个有趣的尝试。然而，这里的问题是，当移植的碎片已经从天然珊瑚群落中取出时，它往往会导致一系列潜在的问题，例如供体群落的繁殖力下降，对被开发珊瑚的周围环境的负面影响以及移植碎片的物种多样性低。在本文中，我们研究了商业珊瑚移植在海洋生态系统保护中的优点，并提出了一些改革，可以帮助减轻使用有性繁殖珊瑚移植时遇到的问题。最后，我们讨论了冲绳商业移植如何应用于其他海洋生态系统的保护。
The deterioration of coral reefs in Japan is a serious environmental problem. Conventional conservation policies for terrestrial ecosystems are sometimes difficult to apply to coral reef protection because of the large number of stakeholders involved. In what seems to be an interesting attempt to solve this problem, tourist divers in Okinawa, Japan have begun to transplant coral fragments onto deteriorated coral reefs, by participating in a tour provided by diving shops. However, the problem here is that when the transplanted fragments have been taken out from the natural coral colonies, it tends to cause a host of potential problems such as decreasing fecundity of donor colonies, negative effects on the surrounding environment of the exploited corals and low species diversity of transplanted fragments. In this paper, we examine the merits of commercial coral transplantation in marine ecosystem conservation, and to suggest some reforms that could help to mitigate the problems encountered when using sexually propagated coral transplants. Finally, we discuss how the commercial transplantation in Okinawa could be applied to the conservation of other marine ecosystem.
