It is the mixture that forms in the part farthest from the sea, at the point where the current of the river has more force than the current of the sea. This area is called the famous “bottle neck” is also where the most delicate and small fish live, has a specific gravity that can be established according to the species, from 1,002 to 1,006.
However, it can cause damage to the environment, as it is detrimental to organisms that have not adapted to it. This becomes a problem when this water is deliberately grown, as is done in some regions of fish farms for human consumption. They also have an unpleasant taste to drink and can cause health problems.
The term “brackish” was used for the first time to describe the parts of drinking water that had been contaminated by seawater in the year 1500. The mixture of salt and fresh water creates slightly salty water that is no saltier than the water of the sea.
Sea, but still in bad taste. Many people also observed that water was harmful, due to the unique microorganisms that cause human diseases that develop in it. In nature, estuaries are a common site for brackish water. An estuary is a place where marine water and fresh water mix, usually around the opening of a river. The environment of the estuary is very peculiar since it unites the oceans and the rivers; they contain fish, plants and unique animals.
When the balance of an estuary is altered, it can be serious for the animals that inhabit the area of origin. Much anadromous fish appreciate estuaries because the slow change in salinity allows fish to adapt easily. In this other beautiful aquarium it shows off with its fish and rocks:
They can be represented in large tanks or larger than 100 lt, where an exquisite mixture of plants, rocks and woods is selected to replenish not a landscape but a piece of mangrove, whose job is to prevent much fresh water from flowing into the ocean and not too much sea water to enter the course of fresh water and land, making this area the most important natural brackish area.
The mangroves are named after the tree that creates them and I say well, the mangrove transforms the landscape like few species and is capable of turning a sandy and apparently sterile estuary into an impenetrable hell overflowing with life outside and inside the water. The mangrove survives the salt water and is capable of reproducing by sticking its fruits in the sandy bottom. The formation of multiple subterranean and aerial roots for breathing constitutes the framework of an aquarium-mangrove aquarium.
They are tropical and subtropical zones of the whole world and with own fauna that in addition, varies in function of the continent. At the level of the aquarium, the majorities of fish found in the field are Indo-Asian and curiously in the matter of reptiles predominate those of the new world. Mangroves are also classically brackish water zones.
Many mangroves are found along the coasts, so they are transition zones of salinity that rise and fall with the tide. Many types of fish and plants that live in these swamps are unique. In some regions, mangroves are an important buffer zone between the ocean and the land, protecting the land from the waves as a result of hurricanes and tsunamis. Semisalada water can also be found in some lakes and inland seas such as the Caspian Sea. Salinity in these lakes and seas can vary, depending on the flow of water and the passage of time.
It is not uncommon to see the stratification of brackish water, with cold salt water at the bottom and hotter and brackish or sweet at the top. Each layer houses different animals and the alteration of the layers can have lamentable results for the local ecology.
