Effective conservation requires that species recovery measures are informed by rigorous scientific research. For imperilled freshwater fishes and mussels in Canada, numerous research gaps exist, in part owing to the need for specialized research methods. The Canadian Freshwater Species at Risk Research Network (SARNET) was formed and identified or implemented approaches to address current research gaps, including (1) captive experimental research populations, (2) nonlethal methods for estimating abundance and distribution, (3) nonlethal field methods to measure life-history parameters, (4) species distribution models informed by co-occurring species, (5) conservation physiology to inform habitat and threat science, (6) evidence syntheses to evaluate threats and recovery measures, (7) disease-transmission models to understand mussel–host relationships, (8) experimental mesocosms and manipulative experiments to evaluate key habitat stressors, (9) threat and hazard models for predictive applications, and (10) rigorous evaluation of surrogate species. Over a dozen threat- and recovery-focused SARNET research applications are summarized, demonstrating the value of a coordinated research program between academics and government to advance scientific research on, and to support the recovery of, imperilled freshwater species.

有效的保护要求物种恢复措施以严格的科学研究为依据。对于加拿大濒临灭绝的淡水鱼类和贻贝，存在许多研究空白，部分原因是需要专门的研究方法。加拿大淡水物种风险研究网络 (SARNET) 成立并确定或实施了解决当前研究差距的方法，包括 (1) 圈养实验研究种群，(2) 估计丰度和分布的非致命方法，(3) 非致命野外方法测量生活史参数，(4) 由共生物种提供信息的物种分布模型，(5) 保护生理学为栖息地和威胁科学提供信息，(6) 评估威胁和恢复措施的证据综合，(7) 了解贻贝-宿主关系的疾病传播模型，(8) 用于评估关键栖息地压力源的实验性中观和操纵性实验，(9) 用于预测应用的威胁和危害模型，以及 (10) 对替代物种的严格评估。总结了十多个以威胁和恢复为重点的 SARNET 研究应用，证明了学术界和政府之间协调研究计划的价值，以推进对濒危淡水物种的科学研究并支持恢复。
