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). There are also a number of biological and physiological differences relating to water and salt retention and excretion.
Sirens are typically found in freshwater environments such as swamps, rivers, and lakes. They are not adapted to live in saltwater habitats and are primarily found in the southeastern United States.
