Acquaculture
An estuary is the place where freshwater and saltwater meet.
Saltwater and Freshwater mixed is called brackish water.
This process is called "saltwater intrusion." It occurs when saltwater moves into and contaminates freshwater sources, typically in coastal areas where there is excessive water extraction from wells or a decrease in freshwater flow.
To make saltwater into freshwater, you can use a process called desalination, which removes the salt content. One common desalination method is called reverse osmosis, where pressure is applied to push saltwater through a membrane, leaving freshwater on one side and concentrated saltwater on the other. Another method is distillation, where saltwater is heated to create steam that condenses into freshwater, leaving the salt behind.
Estuaries

The place where saltwater and freshwater meet is called an estuary. Estuaries are typically found at the mouths of rivers, where freshwater from rivers mixes with saltwater from the ocean. This unique environment supports diverse ecosystems and provides critical habitats for various species of fish and wildlife.
I would believe it to be called Freshwater. In the oceans it would be Saltwater.

Usually an Estuary. In these regions the salt content of the water varies and is commonly called "Brackish water".
