What would happen if I were to put a Freshwater fish in Saltwater?

Question

Besides it dying.

Answer 1

The salt water would cause the tissues of the fish to dry out as osmosis occurs and the fluid of the fish's body tries to dilute the surrounding salt and then the fish would die.

On another note: the freshwater eel lives for part of its life in freshwater then migrates to the bahamas and salty water to breed then die; a very few fish are able to make a jump from fresh to salt water, but other fish live near river drainage areas where the two waters mix and do fine

Answer 2

From "Ask a Scientist":
Answer 1: For most fish, they would die. But some, like eels and salmon, can move
freely between the two at certain stages of their lives. To do this they have special
mechanisms of excretion and absorption of salt and water.--ProfBill

Answer 2: If you put a freshwater fish into saltwater, most fish would lose weight
(from losing water from its body) and eventually die. Approximately 2% of all 21000
species of fish actually move from freshwater to saltwater or from salt to fresh at some
point in their lives, the move would kill any other fish. But even with these special
varieties of fish, the move must be gradual so their bodies can adjust, or they too,
will die from the change. If you want to learn more about why the freshwater fish will
lose water, (or why a saltwater fish in freshwater would gain water), look up the words
"diffusion" and "osmosis".

Answer 3

it will see as if it is in freshwater but after about 5-10 minutes it will slow down and then die. I know this because i feed freshwater feeder fish to my saltwater fish and the feeder fish that dont get eaten survive and then die. It will not float. Its a fish if its in any type of water it will swim!

Answer 4

It would either get really sick or die. I would not do it but if you don't have saltwater try getting freshwater and putting actual salt in it. Well, hope this helps!! Good luck!! :]

Answer 5

There's a fish called Freshwater Eel that can lives in salt water. So it depens on what kind of fish you put. It may die and it may survive.

Answer 6

First, it would struggle in distress near the surface, because it is more buoyant in salt water than in fresh.
Second, it would lose water through its gills.

...and eventually, unless it's one of those dual-adapted fish the others are mentioning, it would die.

I used to feed my pet crab (marine) some gambusias (freshwater).

Answer 7

It would die. Freshwater fish have their organs attapted to freshwater and if they are put it salt water their gills and organs wouldnt work properly.

Answer 8

The fish would shrink in size and then die. This is because water would be expelled out of the fish because of the properties of diffusion.

Answer 9

if u put a freshwater fish in salt water then it will die... i jus went over this in my biology cp class like 2 weeks ago

if u want to kno why it will die then hit me up in a message and i will tell u...

Answer 10

beside die some would float some will sink left there long enough they will stink
