Detailed explanation-1: -The sea water is saline having more concentration of salts and acts as hypertonic solution for the fresh water. So fresh water fish cannot survive in sea water as it causes the plasmolysis of the cells of the fish and ultimately the fish will die.
Detailed explanation-2: -If freshwater fish are put in saltwater, they lose water from their bodies due to the hypertonic environment. Their cells shrivel and die.
Detailed explanation-3: -All fish need an element of salt in the water. Koi carp need between 0.13 and 0.23% of salt in the water. The salt is drawn into their system via osmosis and keep the balance. If salt or freshwater fish are in the wrong water, salt will be drawn in or out of the body and kill the fish.
