they cannot live in salt water because they are not used to that environment. The water is different and they are not used to it. That would be like putting a human that lived in a hot place like Mexico, and putting them in a cold place like Antarctica (with no clothes, equipment, etc.) The human would most likely die due to the extreme temperature change and inability to adapt.

Putting a fish into excess salt water upsets the balance in osmosis, in which cells naturally try to balance the level of salt/other stuff and water inside and outside the membrane. If the fish lives in fresh water, and is dropped into salt water, its outer cells (eyes, mouth, around the scales) will try to get the inside of the cell to match the concentration of salt in the water. This will cause the cells to expel water (salt does not pass though the membranes) and they will shrivel up. Needless to say, this is often fatal for the fish, as this process occurs wherever it is hit by the water. It will live for a while before this occurs, so for very short periods (minutes) it can painfully live in the alternate environment.

If you put a Saltwater Fish into fresh water, the alternate case occurs, and the cells absorb water until they burst, so creating the same outcome.

What kind of fish lives by the delta fresh water fish or salt water fish?

Both kinds of fish can live in a delta area. The line between salt water fish and fresh water fish seems to be getting blurrier. Sharks and other typically salt water fish are found many miles up stream in rivers that empty into the ocean. It appears that salt water fish adapt better than fresh water fish as the fish found in fresh water are not found out at sea.


What water balance problem to salt ocean fish face?

Lets See If This Answers Your Question... Fresh Water Fish have A Liver That Can Process All Kinds of Stuff From Fresh Water. Wether It Be Dirty Water, Clean Water, or Sometimes Even Slightily Toxic Water... But The Transition To Fresh To Salt Lies In The Very Word Itself, SALT WATER... The Liver of A Normal Fresh Water Fish Can Only Handle Bits of Amount of Salt, But The Water In The Ocean Is So Strong That The Liver of A Fresh Water Fish Just Over Loads and Shuts Down Killing The Fish... Thats Why Salt Water Fish Have Evolved Their Livers To With Stand Lethal Amounts of Salt In The Water... The Same With Salt Water Fish, They Can Not Process Fresh Water Because their Livers Are Only Made To Process Salt Not Fresh... Some Fish Actually Can Do Both Like The BULL SHARK, Salman, (not a fish) Salt Water Crocidile...
