This has already been explained in my answers to varied similar questions in … Flex your freshwater fish knowledge here. Some things can cross the barrier, others can't. Salt is a solute, which means that it is a substance that can be dissolved in a solvent; which in this case is water. The amounts and concentrations of the elements, however, usually vary according to the species and the characteristics of the water in which they live.

But unlike their freshwater brethren, they don’t have to do as much urination, since water is always passively leaving their system instead of entering. Once they have achieved this, they can survive in the salt water conditions. In this way, when the fish drink water, leftover salts which will not be used in a fish’s body, are secreted through cells present in their gills.

They can't break down the water molecule (which is H2O — two atoms of hydrogen and one atom of oxygen). For fish living in water, the need to drink is regulated by passive biological processes that vary depending on whether they live in fresh or salty water; and to a certain extent, their species. Lots of water will passively enter fish cells via, If your fish is in saltwater (the water is saltier than the fish), a lot of water is going to be coming out of the fish cells, so the cells would just shrivel up if the fish didn’t do anything. Urinating is a completely normal and essential organic function in these animals. So, let's now look at how this applies to a fish, starting with a freshwater species. These fish then drink water to regulate salt levels in the body and avoid dehydration, a completely normal phenomenon whereby they lose water through the skin.
