More than 15 years have passed since Canada’s Species at Risk Act was enacted. To evaluate scientific progress in support of the Act, we identified research accomplishments up to 2017 for imperilled aquatic species in the Great Lakes – St. Lawrence River basin based on recovery documents and an expert survey, spanning 1182 activities across 68 research topics for 45 fish and mussel species. Greatest progress was observed for population ecology (38% of activities with major progress) and habitat science (28%), with comparably less progress on threats (mechanisms and impacts; 19%) and recovery (threat mitigation and reintroduction; 21%). As a result of lagging progress, threat and reintroduction topics were prioritized for a Canadian Freshwater Species at Risk Research Network (SARNET; 2017–2020), which focused on addressing key knowledge gaps with novel applications. This special issue outlines the SARNET projects, which span novel field, laboratory, and analytical activities. Continued research investment into novel and existing approaches is necessary to advance scientific achievements for fishes and mussels in support of the Species at Risk Act in Canada.

加拿大濒危物种法案十五年：评估五大湖区水生物种的研究进展 - 圣劳伦斯河流域

加拿大渔业和水产科学杂志，提前印刷。
自加拿大《濒危物种法案》颁布以来，已经过去了 15 年多。为了评估支持该法案的科学进展，我们根据恢复文件和专家调查确定了截至 2017 年大湖区 - 圣劳伦斯河流域濒危水生物种的研究成果，涵盖 45 种鱼类的 68 个研究主题的 1182 项活动和贻贝种类。人口生态学（38% 的活动取得重大进展）和栖息地科学（28%）取得了最大进展，威胁（机制和影响；19%）和恢复（威胁减轻和重新引入；21%）的进展相对较少。由于进展滞后，加拿大淡水物种风险研究网络（SARNET；2017-2020）优先考虑威胁和重新引入主题，它专注于通过新颖的应用解决关键的知识差距。本期特刊概述了跨越新领域、实验室和分析活动的 SARNET 项目。有必要对新的和现有的方法进行持续的研究投资，以推进鱼类和贻贝的科学成果，以支持加拿大的《濒危物种法案》。
