Title is self explanatory. Do freshwater fish ever accidentally find themselves in brackish or saltwater? How do they deal with that?

There’s not a definite line between salty water and fresh water.
Generally rivers will end with a delta, where the tides change the salinity of the water.
There’s some fish that can survive in this environment, but generally they’ll just keep to fresher waters.
Catastrophic events like a flood can cause them to be washed out to sea. Unless they make it back to fresh water quickly, they will die.
