Freshwater fish derive small amounts of salt from their freshwater habitat. If you place a freshwater fish in saltwater, the difference in habitat will cause the fish to burst.
The question needs to be refined, as there are hundreds of freshwater fish species.
There are freshwater drum, and saltwater drum species.
Saltwater fish have a natural habitat in the sea. Whereas, freshwater fish has a habitat in a river or a lake.
Humans eat freshwater shrimp. In their natural habitat, freshwater shrimp are often eaten by larger fish. The California freshwater shrimp is considered an endangered species, and is under protection.
By keeping freshwater environments clean, habitat remains suitable for this super abundant sunfish species.
It really depends on what fish you're studying. If you put a fish that lives in freshwater into saltwater, it will die. So your answer is, Freshwater Fish live in ponds, lakes, and freshwater rivers. Saltwater Fish live in oceans and seas. I hope this helps.
