The Convention on the Conservation of Migratory Species of Wild Animals (CMS) provides a global framework for protecting migratory species, yet freshwater fishes remain underrepresented in the CMS appendices. Strengthening links between research, science communications, policy development and CMS implementation can generate synergistic effects that enhance conservation of migratory freshwater fishes.
