Freshwater fish that wind up in seawater will have a similar experience, eventually dying as their bodies become overly dehydrated
. It's critical that fish use osmosis to regulate salt in their bodies.
How do you rehydrate fish?

So fish need to
drink lots of seawater
to stay hydrated. And because seawater is so salty, they also must pump out the excess salt, both through their kidneys and using specialized cells in their gills.

18 months to three years
.
Can you rehydrate dried fish?
In the re-hydrating stage, the dried fish is left to stand in a tank of preferably cold water for several hours
. The ratio of the quantities of fish to water affects the amount of salt that is dissolved out of the fish, which affects the final taste of the product. A ratio of fish:water of 1:20 gives good results.
Why do most fish live in salt water?
Here is his answer. The reason some fish normally live in freshwater and others live in seawater is that
one or the other environment provides them with opportunities that have traditionally contributed to their survival
. An obvious difference between the two habitats is salt concentration.
How do fish deal with salt?
To stop the exploding fish phenomenon,
their gills have special cells that selectively pump salt in, or out of their blood
. In freshwater fish, the cells constantly pump salt in, and in saltwater fish, they constantly pump salt out. Saltwater fishes' kidneys also help to filter out some of their salt.

Do fish ever drink water?
Freshwater fish never drink water
because their bodies are saltier than the surrounding water. Osmosis draws water into the fish's body through its skin and gills, unlike saltwater fish, where the water is drawn out of the body.
Why is electrofishing done at night?
1) Safety – although the field of electricity is very localized to the front of the boat, between 250 and 500 volts is directed into the water, generally at 4 to 6 amperes. Electrofishing surveys are done at night
when the lake is quiet and there is less chance of people or pets swimming in areas being surveyed
.
Does fish get thirsty?
They don't ever get thirsty
. Marine fish are what's called hypertonic to the seawater. So essentially, they lose water through their gills to the seawater. The seawater is saltier than their blood.

By making alcohol, crucian carp and goldfish can survive where no other fish can
, meaning they can avoid predators or competitors.
Can fishes pee?
Fish urinate either through their gills or through a “urinary pore.”
The latter eliminates urine that has been filtered via the kidneys. Saltwater varieties excrete most urine through the gills, while freshwater fish do so through the urinary pore. Saltwater fish take in a great deal of salt and must excrete it.
