Which migratory pattern describes species that spawn in freshwater after maturing in saltwater?

Anadromous describes a life cycle in which species grow up in saltwater and then migrate into freshwater to spawn. This matches the idea of maturing in the ocean and returning to freshwater to reproduce, as seen in salmon. The other terms don’t describe this migratory pattern: catadromous is the reverse—mature in freshwater and spawn in saltwater; oviparous and viviparous refer to egg-laying and live birth, not migration.
