A Meta‐Analysis on Environmental Triggers of Spawning Migrations Reveals a New Classification of Thermal Guilds in European Freshwater Fishes

open access: yesFish and Fisheries, Volume 27, Issue 3, Page 478-495, May 2026.
ABSTRACT Fish migration through river networks is essential for completing life cycles and accessing critical habitats, but fragmentation increasingly disrupts spawning movements. In Europe, over one million barriers limit connectivity and create trade‐offs between ecological integrity and human uses, such as hydropower, flood control, fisheries and ...
