I think the term you want is "sporadic salt-tolerant fresh-water fish."
There are 6 classifications of salt-tolerant fresh-water fish all based on time and habits those fish spend in salt water.
* Primary Fresh water only
* Secondary Fresh water, with short term salt tolerance
* Vicarious Saltwater only
* Complementary A Diadromous that only takes over fresh water habitat in the absence of primary and secondary fish
* Diadromous Migratory fish that live in different types of water at different stages of life
* Sporadic Lives and breeds in either type of water typically without migration
If you mean the fish can originate in fresh water, go into salt water to grow and then go back into fresh water to breed (like some Salmon species) the term to describe this is (anadromous).
