The direct opposite of “anadromous” is “catadromous.” Anadromous fish are born in freshwater that migrate to the ocean as juveniles, and they grow into adults before migrating back into freshwater to spawn; catadromous species are born in saltwater. They migrate into freshwater as juveniles, grow into adults, then migrate back into the ocean to spawn.
