Freshwater fish have been widely introduced worldwide, and freshwater ecosystems are among those most affected by biological invasions. Consequently, freshwater fish invasions are one of the most documented invasions among animal taxa, with much information available about invasive species, their characteristics, invaded regions, invasion pathways, impacts, and management. While existing reviews address specific aspects of freshwater fish invasions, there is still a gaping lack of comprehensive assessments of freshwater fish invasions that simultaneously address pivotal and connected elements of the invasion process. Here, we provide a holistic review, together with quantitative assessments, divided into four major parts: ( a) introduction pathways, ( b) characteristics of nonnative species andinvaded ecosystems that explain successful invasion processes, ( c) invasion impacts and their mechanisms, and ( d) management. We highlight data gaps and biases in the current databases and highlight a basic lack of understanding of several aspects of freshwater fish invasions. In addition, we provide recommendations for future studies.

淡水鱼入侵：全面回顾


淡水鱼已在世界范围内广泛引入，淡水生态系统是受生物入侵影响最严重的生态系统之一。因此，淡水鱼类入侵是动物类群中记录最多的入侵之一，有大量关于入侵物种、其特征、入侵区域、入侵途径、影响和管理的信息。虽然现有的审查涉及淡水鱼入侵的具体方面，但仍然严重缺乏对淡水鱼入侵的全面评估，同时解决入侵过程中的关键和相关要素。在这里，我们提供了全面的回顾和定量评估，分为四个主要部分：（a）引入途径，（b）解释成功入侵过程的非本地物种和入侵生态系统的特征，（c）入侵影响及其机制，以及（四）管理。我们强调了当前数据库中的数据差距和偏差，并强调了对淡水鱼类入侵的几个方面基本缺乏了解。此外，我们还为未来的研究提供建议。
