Can a fish be dehydrated?

Generally, it may take up to 10 hours for fish to dry. Many factors may influence how long or how fast your fish dries, such as how humid it is where you are, thickness of strips and the amount of fish in the dehydrator. Your best bet is to check on your fish as it dries and test it.
As well as getting water through osmosis, saltwater fish need to purposefully drink water in order to get enough into their systems. Where their freshwater counterparts direct all of the water that comes into their mouths out through their gills, saltwater fish direct some into their digestive tract.
Why do fish not get thirsty?
in order to replenish that water, they have to drink seawater and process the salt out. But they live in seawater constantly. They can drink whenever they like. So really, they’re never going to get thirsty because they’re going to drink tiny amounts of seawater as and when they need it and keep themselves topped up.
Fish don’t have to worry about getting thirsty because they live in water and can absorb water through their skin and gills. Seawater fish drink water to avoid dehydration, while freshwater fish don’t drink water because they have a higher salt concentration in their blood than in the water they are surrounded by.
