Has anyone tried to do this or is it posibble? and would it possibilly make a fish imune to salt water and fresh water?

It wouldnt have to mate under normal circumstances, we could have scientists manualy put the sperm in the egg.

They couldn't mate even through artificial insemination as the previous answer stated. they are completely different species.
Even if offspring were created by this union they would be sterile.
Like a mule.
Making freshwater fish immune to salt water would take genetic engineering.
However there are some salt water species that do spend a considerable amount of time in fresh water. (some sharks etc...)

Saltwater fish typically do not mate at all in captivity. No, it would not be possible to make a fish immune to salt and fresh water. What other environment would they live in then?

Then there are the salmon that are born in fresh water but live most of their lives in the sea only to go back up the freshwater and die…
although they are not “immune” to either.

It's not possible...they're too genetically different. There are some fish that can tolerate both fresh and saltwater. Salmon and bull sharks come to mind....there are probably some others.
