Abstract Context Improving the welfare outcomes for captured animals is critically important and should underpin ‘best-practice’ trapping. Most Australian States and Territories have regulations and guidelines that form a legal framework for the maximum number of hours an animal can be restrained in a trap. Because servicing all traps within preferred time frames (less than 24 h) can be logistically difficult or is considered undesirable for efficacy reasons, some jurisdictions have adopted relatively long trap-checking intervals (up to 72 h). Aims We developed and tested the signal transmission and alert efficacy of a foot hold-trap alert system, based on Celium technology, so as to advise trappers of the activation of individual foot-hold traps, even in remote locations. Methods We refined the Celium trap-alert system and designed a below-ground wireless node that transmits a message via satellite or by using the cellular system when a foot-hold trap is sprung. We tested signal transmission and alert efficacy in three locations, with a focus in Australia. Key results Transmission of signals from nodes to hubs and to a smart-phone application were used to resolve interference problems and to identify signal limitations and strengths. During the capture of 34 dingoes, 91% of captures resulted in an alert being received. False negatives were attributed to technical issues with nearby transmitters swamping signals, and software problems that have since been resolved. In 40 captures of dogs and foxes, only one trap-alert transmitter (mole) was uncovered by a target animal and no devices were damaged by animals post-capture. Conclusions This cable-less trap-alert system successfully uses both cellular and satellite networks to transmit messages from desert and coastal locations to trappers, in Australia. We confirmed that this trap-alert system is not detected by target predators in the areas tested and can be effectively used to alert trappers when traps have been sprung. Implications This trap-alert system provides a tool to improve welfare outcomes for trapped target and non-target animals through Australia and New Zealand and wherever trapping occurs. It, furthermore, provides a solution to checking traps daily when the distance to and between traps cannot be covered within an appropriate time frame. Although trap alerts can never replace the value of daily trap checking by the trapper, they provide a solution to a management problem, namely, one of accessibility to sites.

用于诱捕落脚点的卫星和电信警报系统

摘要 背景 改善被捕获动物的福利结果至关重要，应成为“最佳实践”诱捕的基础。大多数澳大利亚州和领地都制定了法规和指导方针，形成了一个法律框架，规定动物可以被限制在陷阱中的最大小时数。由于在首选时间范围内（少于 24 小时）维修所有捕集阱可能在后勤上很困难，或者出于有效性原因被认为是不可取的，因此一些司法管辖区采用了相对较长的捕集阱检查间隔（最多 72 小时）。目标我们开发并测试了基于 Celium 技术的足部陷阱警报系统的信号传输和警报功效，以便即使在偏远地区也能建议捕捉者激活单个足部陷阱。方法 我们改进了 Celium 陷阱警报系统，并设计了一个地下无线节点，该节点通过卫星或在出现立足点陷阱时使用蜂窝系统传输消息。我们在三个地点测试了信号传输和警报功效，重点是澳大利亚。主要结果 从节点到集线器和智能手机应用程序的信号传输被用来解决干扰问题并确定信号限制和强度。在捕获 34 只澳洲野狗期间，91% 的捕获导致收到警报。误报归因于附近发射器淹没信号的技术问题，以及此后已解决的软件问题。在 40 次捕捉狗和狐狸的过程中，目标动物仅发现了一个陷阱警报发射器（鼹鼠），并且在捕获后动物没有损坏任何设备。结论 这种无电缆陷阱警报系统成功地使用蜂窝和卫星网络将信息从沙漠和沿海地区传输到澳大利亚的捕猎者。我们确认该陷阱警报系统不会被测试区域的目标捕食者检测到，并且可以有效地用于在陷阱出现时提醒捕食者。影响 该陷阱警报系统提供了一种工具，可以改善澳大利亚和新西兰以及发生陷阱的任何地方的被困目标和非目标动物的福利结果。此外，当无法在适当的时间范围内覆盖到陷阱和陷阱之间的距离时，它提供了一种每天检查陷阱的解决方案。
