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 and invaded ecosystems that explain successful invasion processes, (c) invasion impacts and theirmechanisms, 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. specialized MONDE 034 036 53 427-456 2022 1543-592X https://www.documentation.ird.fr/hor/fdi:010086708 10.1146/annurev-ecolsys-032522-015551 1543-592X [F B010086708] https://www.documentation.ird.fr/hor/fdi:010086708 https://www.documentation.ird.fr/intranet/publi/2023-01/010086708.pdf Accès réservé (Intranet de l'IRD) IRD - Base Horizon / Pleins textes 2023-01-11 2025-02-24 fdi:010086708 fre
