Monitor the adaptation of released captive-raised Amazonian manatees to the wild by animal-borne recorders

总体目标是监测释放的圈养亚马逊海牛适应野外生活的情况，以改善康复计划。海妖是唯一现存的食草水生哺乳动物。尽管利用沿海浅水栖息地，很多仍然未知的喂养行为，由于限制，特别是居住在黑暗的水域栖息地的类群：亚马逊海牛。关于释放海牛的一个重要问题是，当他们喂养自己一旦释放。在这项研究中，我们专注于直接记录海牛喂养的声音。我们的目标是从记录的声音中检测进食事件，以便了解海牛在释放到野外后何时，什么样的植物以及吃了多少。

The overall objective is to monitor the adaptation of released captive-raised Amazonian manatees to the wild in order to improve the rehabilitation program. Sirenians are the only extant herbivorous aquatic mammals. Despite utilizing coastal shallow habitats, much remains unknown about the feeding behaviour due to the limitations, especially for taxa that inhabit dark water habitats: Amazonian manatees.One of the vital questions about released manatees is when they are feeding on their own once released. In this study, we focused on the direct recording of the manatee feeding sounds. We aim to detect the feeding events from the recorded sound in order to understand when, what kind of plants, and how much the manatee eat after releasing into the wild.
