We developed a long-term tagging method that can be used to understand species assemblages and social groupings associated with large marine fishes such as the Sand Tiger shark Carcharias taurus. We deployed internally implanted archival VEMCO Mobile Transceivers (VMTs; VEMCO Ltd. Nova Scotia, Canada) in 20 adult Sand Tigers, of which two tags were successfully recovered (10%). The recovered VMTs recorded 29,646 and 44,210 detections of telemetered animals respectively. To our knowledge, this is the first study to demonstrate a method for long-term (~ 1 year) archival acoustic transceiver tag implantation, retention, and recovery in a highly migratory marine fish. Results show low presumed mortality (n = 1, 5%), high VMT retention, and that non-lethal recovery after almost a year at liberty can be achieved for archival acoustic transceivers. This method can be applied to study the social interactions and behavioral ecology of large marine fishes.
我们开发了一种长期标记方法，可用于了解与沙虎鲨（Carcharias taurus）等大型海洋鱼类相关的物种组合和社会群体。我们在20条成年沙虎鲨体内植入了档案型VEMCO移动收发器（VMTs；加拿大新斯科舍省VEMCO有限公司），其中两个标签成功回收（10%）。回收的VMTs分别记录了29646次和44210次遥测动物的探测。据我们所知，这是第一项展示在高度洄游的海洋鱼类中进行长期（约1年）档案声学收发器标签植入、保留和回收方法的研究。结果显示假定死亡率较低（n = 1, 5%），VMT保留率较高，并且对于档案声学收发器而言，在自由生活近一年后可以实现非致死性回收。这种方法可应用于研究大型海洋鱼类的社会互动和行为生态学。
