Captive breeding programs are one of the many tools used by conservation practitioners as a means of conserving, supporting, and supplementing populations of imperilled species. Captive breeding programs exist around the globe for freshwater mussels and fishes, but the availability of evidence exploring the effectiveness of these programs has not yet been explored using systematic map criteria. This systematic map aims to identify, collate and describe the evidence that exists on the effectiveness of captive breeding programs, for the purpose of achieving conservation targets for imperilled freshwater fishes and mussels in the wild. The outputs of this systematic map will help to inform conservation managers and policy makers who are responsible for protecting imperilled freshwater species by identifying existing information and highlighting key information gaps for captive breeding programs operating in temperate regions. This systematic map will search for, compile, and map existing literature on the effectiveness of captive breeding programs for the conservation of imperilled freshwater fishes and mussels. The systematic map will search using five bibliographic databases, two public search engines, and 19 specialist websites and will include both primary and grey literature. All studies that discuss details related to captive breeding programs for the conservation of imperilled freshwater fishes and/or mussels in temperate regions will be included in the map. The systematic map will produce a narrative report describing the evidence, including knowledge gaps evidence clusters, and a MS-Excel searchable database of articles and extracted metadata.

圈养繁殖和释放计划能否实现对濒临灭绝的淡水鱼和贻贝的保护目标？确定可用证据的系统地图方案

圈养繁殖计划是养护从业人员用来保护，支持和补充濒危物种种群的众多工具之一。淡水贻贝和鱼类的圈养繁殖计划在全球范围内存在，但是尚未使用系统的地图标准来探索探索这些计划有效性的证据。该系统地图旨在确定，整理和描述有关圈养繁殖计划有效性的证据，以实现对野生野生濒危淡水鱼和贻贝的保护目标。该系统地图的输出将通过识别现有信息并突出温带地区实施的圈养繁殖计划的关键信息空白，从而有助于向负责保护濒危淡水物种的保护管理人员和决策者提供信息。该系统地图将搜索，汇编和绘制有关圈养繁殖计划对保护淡水鱼类和贻贝的有效性的现有文献。系统地图将使用五个书目数据库，两个公共搜索引擎和19个专业网站进行搜索，并将包括原始文献和灰色文献。所有讨论与圈养繁殖计划有关的细节的研究都将纳入地图，这些繁殖计划旨在保护温带地区的濒危淡水鱼和/或贻贝。
