In support of World Fish Migration Day, we would like to present a comprehensive database that details the migratory life histories of freshwater fishes in North America. The database can be obtained from USGS at https://www.sciencebase.gov/catalog/item/619d2dbcd34eb622f6951e8a and an article on the database has been published by the Journal of Biogeography (https://doi.org/10.1111/jbi.14367).

Description: Migratory freshwater fishes are those that must access discrete habitats to complete their life cycles and their migrations occur around the world and provide numerous ecosystem services for humans and natural systems; however, many migratory species are in decline globally. A limiting factor to successfully conserve freshwater migratory fishes is that the migratory life histories of many species are unknown or only partially described. To provide researchers with critical and comprehensive information to conserve migratory fishes, we developed the North American Freshwater Migratory Fish Database (NAFMFD). The database synthesizes current knowledge of migratory status, pattern and behaviour of native and non-native freshwater fishes throughout North America, including 1250 species representing 79 families and 325 genera. Results highlight the diversity of migratory life histories of freshwater fishes on the continent, including that at least 25% of North American freshwater fishes are migratory, 23% are non-migratory and 44% have undetermined migratory status. NAFMFD improves the quality of migratory data accessible to researchers, which supports a more holistic understanding of the threats encountered by migratory fishes, including habitat fragmentation. Collectively, this work offers new insights into the range of freshwater fish migratory life histories, stimulating a need to better understand this diversity globally.
