摘要
为探求提高大鲵（Andriasdavidianus）增殖放流成功率及其监测的有效方法，通过对浙江省庆元大鲵国家级自然保护区内增殖放流点周边环境选择及大鲵生存状况的追踪调查，分析了不同生境、不同饵料组成、水质情况对增殖放流大鲵成活及生长的影响，探讨了影响大鲵生存的因素，并分析了3种标记方法的优缺点。结果表明，选择具有深穴或岩石覆盖洞穴多、饵料鱼类资源丰富、水质优良且水流较缓的实验地作为增殖放流点，有利于放流大鲵的存活和生长。3种标记方法的对比表明无线电动物标签效果最好，荧光标记次之，打烙印标记方法不宜采用。
The influence of habitats environment and prey composition and water quality on growth of Andrias davidianus in Qingyuan aquatic germplasm resources reserve was analyzed to improve the successful rate of A. davidianus enhancement . Three marking and tagging methods were analyzed and compared to explore an effective monitoring method. The results showed that the spot which had deep hole or rock cover cave, abundant bait resources, good water quality and slower water flow was advantageous to the survival and growth of artificial-bred A. davidianus in the wild. Radio tags was the best in three methods, fluorescence labeling was better, branding mark method should not be used because it cause body damage and induce water mildew consequently.
