There are many people who want to try their hand at raising brackish water fishes. But wonder what brackish water is and what is the list of brackish water fishes that are easy to keep? Let’s go with AgriSearch.net to find out the list and characteristics of brackish water fishes!
What is brackish water?
Brackish water is water with a higher salinity than fresh water but not as high as salt water. It could also be the result of mixing of seawater with fresh water, it occurs in estuaries, or it can occur in brackish fossil aquifers.
What is brackish water?
Certain human activities can also produce brackish water, for example in some civil engineering projects such as coastal dikes or the flooding of coastal wetlands to create brackish water ponds and lakes for brackish shrimp farming.
Or it is possible that the primary waste of salinity gradient energy technology can also produce brackish water.
Perhaps because brackish water is not suitable for the growth of most land plants, without proper management and control it can cause environmental damage.
List of brackish water fish in our country
Seabass also known as sea bass, they often live in rock caves or seagrass bottoms. Seabass is a typical fierce fish in estuaries, with a large number in canals, lagoons and especially in shrimp ponds.

In Vietnam, red snapper is a valuable fish species, this fish accounts for about 10-12% of bottom fish production in the Gulf of Tonkin.

Hopefully with the above information, you already know what brackish water is and what types of brackish water fish can be raised in this area. Hope the article can be of help to you.
Happy successful people.
