Do fish drink fresh water?

"The answer to this question differs, depending on whether you're talking about saltwater fish or freshwater fish. Freshwater fish do not actively drink water, but absorb the water through their skin and gills. On the other hand, saltwater fish do actively drink sea water. Their gills process the water and take out the salt. The salmon is an interesting example of a fish that lives in both fresh and salt water, and consequently, they have the characteristics of both types of fish. Salmon are born in fresh water, and migrate to the ocean. While living in the ocean, they drink saltwater by opening their mouth; their gills then rid their bodies of the salt and minerals. When the salmon enters freshwater streams to spawn, they stop drinking the water and instead absorb it through osmosis (osmosis means that the water passes through the cells of the fish's skin into its body).


How does mucus help salmon?

Mucus helps salmon by providing a protective barrier on their skin and gills, which helps prevent infections from pathogens and parasites. It also aids in osmoregulation, helping to maintain the balance of salts and water in their bodies as they navigate different aquatic environments. Additionally, mucus can enhance their ability to swim by reducing friction in the water. Overall, it plays a crucial role in the health and survival of salmon.
