This proposal describes a purchase of acoustic telemetry equipment to support significant research activities on migratory fish species in the Linnansaari research laboratory at the University of New Brunswick. Overall, 50 passive acoustic receivers and necessary deployment and maintenance parts will be acquired. Three different varieties of passive receivers are being purchased because of the range of freshwater to ocean conditions necessitating different features onboard the receivers; the receivers range from basic data storage functions to Bluetooth data transmission and automated “pop-off” release systems. Additionally, an active tracking receiver unit will be acquired to facilitate fine-scale movement and behaviour studies. The acoustic tracking equipment will be used to support six ongoing, two starting, and one planned telemetry projects wherein minimally 11 highly qualified personnel, including three members of First Nations, are trained as aquatic telemetry specialists. The supported projects study the migration ecology of three sea-run and one landlocked Atlantic salmon populations, two spatially distinct American eel populations, and a population of shortnose sturgeon, striped bass, and sea-run brook trout, in a timeframe between 2021-25. All but one of the studied migratory fish populations are already considered for listing with a conservation status by the Committee on the Status of Endangered Wildlife in Canada, or are in severe decline; one of the studied fish populations is exponentially increasing, raising questions of interactive predatory effects on the other co-occurring fish populations. Depending on the studied fish population, the objective of the acoustic telemetry studies is to either i) better understand the causes for the continued decline (e.g., mortality rates, reasons and locations), ii) identify significant habitat areas for conservation or management action, iii) confirm the efficiency of current mitigation measures (e.g., efficiency of fish passage structures in hydropower context) or iv) understand the effect of population recovery of a fish predator on other migratory fish populations inhabiting the specific river system. All fish populations studied by using the proposed equipment are socio-economically important species that have historically attracted significant fishing tourism, and thus, economic spin-off in Atlantic Canada. Understanding the causes of the current declines or effectiveness of mitigation will help fisheries managers better protect these populations for future Canadian generations. In addition, all these species are of traditional and cultural importance and are significant for food and ceremonial purposes for local Mi'kmaq and Wolastoqey communities who are also active participants in the field research of this proposal.

该提案描述了购买声学遥测设备的购买，以支持新不伦瑞克大学Linnansaari研究实验室中有关候选鱼类的重要研究活动。总体而言，将获取50个被动声音接收器以及必要的部署和维护零件。由于接收器上的不同特征所必需的不同特征的淡水范围，因此购买了三种不同的被动接收器。接收器范围从基本数据存储功能到蓝牙数据传输和自动化的“ pop-off”发布系统。此外，将获得一个主动跟踪接收器单元，以促进精细的运动和行为研究。 声学跟踪设备将用于支持六个正在进行的，两个起始和一个计划的遥测项目，其中最少的11名高素质的人员，包括三个民族的三名成员，被培训为水上遥测专家。支持项目研究了三个海洋跑步和一个内陆大西洋鲑鱼种群的迁移生态，两个在空间上不同的美国鳗鱼种群，以及2021 - 25年之间的时间范围内，有一个空间上不同的美国鳗鱼种群，一个小的矮小st鱼，条纹鲈鱼和海溪鳟鱼。除一名研究生的迁徙鱼类种群外，所有其他人都已考虑列出加拿大濒危野生动植物状况的咨询状况，或者处于严重下降； Studiod鱼类种群之一是指数增加，这引发了对其他同时发生鱼类种群的互动掠食性影响的问题。根据研究的鱼群的不同，声学遥测研究的目标是i）更好地了解持续下降的原因（例如，死亡率，原因和位置），ii）ii）ii）识别出重要的栖息地领域，以保护或管理行动，iii III）确认了当前的疾病效率或在水中的效率（例如，水域的效率）的效率（例如，水域的效率）（例如，iv的效率），IV的效率），IV的效率），IV的效率））IV的效率））IV的效率））居住在特定河流系统的人群。 使用拟议的设备研究的所有鱼类种群都是社会经济上重要的物种，在历史上吸引了大量的捕鱼旅游业，因此在加拿大大西洋上衍生了经济衍生物。了解当前下降或缓解有效性的原因将有助于渔业经理更好地保护这些人群将来的加拿大世代。此外，所有这些物种都具有传统和文化的重要性，对于当地的Mi'kmaq和Wolastoqey社区而言，他们也是该提案现场研究的积极参与者而言。
