The difference is saltwater fish tend to live in environments where there is salt available in the water (oceans) and freshwater fish live in environments that lack in salt(rivers, ponds, streams).

Oceans and seas are comprised of saltwater, and rivers are comprised of freshwater(drinkable, or potable)
It varies, but usually the rivers freshwater mixing into saltwater.
