Over the past five years, EM Fluids of Ottawa (ON) has made a highly disruptive discovery that the physicochemical properties of water respond to highly specific signals generated by electromagnetic devices. With a power input of less than 0.1 watt, these signal can affect the physicochemical properties of water as far as 150 metres from the transducer (i.e., the "EMF device"). Notably, the device increases the interfacial gas transfer rate such that it is possible to rapidly increase dissolved oxygen concentrations in surface waters. Although there is no electromagnetic emission detectable outside the device, there remain uncertainties regarding if the device impacts aquatic life such as fish. This uncertainty impedes the ability to consider broader roll-outs in the field. This partnership brings together an applied fish ecologist (Dr. Cooke) and a limnologist (Dr. Vermaire) with engineers from EM Fluids in a collaborative framework to evaluate the effects of the EMF device on fish. Field and lab studies will be conducted to determine if the device has any negative effects on fish behaviour, physiology, condition and survival. There is a dire need to develop solutions that mitigate issues such as hypoxia so resolving this issue has the potential to enable the restoration of degraded aquatic ecosystems. Through direct interaction between the academic research team and industry partner, knowledge will be transferred to inform future design refinements and application of this device.

在过去的五年里，渥太华 (ON) 的 EM Fluids 取得了一项极具颠覆性的发现，即水的物理化学特性会对电磁设备产生的高度特定的信号做出反应。 输入功率小于 0.1 瓦时，这些信号可以影响距离传感器（即“EMF 设备”）150 米远的水的物理化学特性。 值得注意的是，该装置增加了界面气体传输速率，从而可以快速增加地表水中的溶解氧浓度。 尽管在设备外部没有检测到电磁辐射，但该设备是否影响鱼类等水生生物仍存在不确定性。 这种不确定性阻碍了考虑在该领域进行更广泛推广的能力。 此次合作将应用鱼类生态学家（Cooke 博士）、湖泊学家（Vermaire 博士）与 EM Fluids 的工程师聚集在一个协作框架中，以评估 EMF 设备对鱼类的影响。 将进行现场和实验室研究，以确定该装置是否对鱼类行为、生理、状况和生存产生负面影响。 迫切需要开发缓解缺氧等问题的解决方案，因此解决这个问题有可能恢复退化的水生生态系统。 通过学术研究团队和行业合作伙伴之间的直接互动，知识将被转移，为该设备的未来设计改进和应用提供信息。
