Some marine fish can live in fresh water. But most marine fish are adapted to salt water; because of the salt in the water their body needs to do things differently, and they are used to being in salt water. If you put them in fresh water, their body can't do the same thing, therefore most of them die. For more information, see the related question.

It is about osmoregulation. Salt water fish has some level of salt in its cells, which is low in concentration than marine water and more than the freshwater. If you put a saltwater fish in fresh water, excess amount of water will enter the cells of the fish and the cells rupture. This is why salt water fish cannot survive in freshwater.
