It is called as aquaculture both to study as to the technique of cultivating living species, animals and plants, either in salt or fresh water.
It should be noted that it is considered one of the most important economic activities in the world, since through it it is possible produce food for people, raw materials that once obtained can be used for industrial or medicinal use or simply produce aquatic beings that will be opportunely used to repopulate some areas, as a domestic company or with an ornamental purpose.
As previously indicated, aquaculture can be practiced in both fresh and salt water, that is, in the sea itself, but it can also be carried out in specially prepared and controlled environments for the activity.
Among the most common species cultivated are microalgae, crustaceans, clams, oysters, mussels and mollusks.
Aquaculture, also called aquaculture For many it is a truly millenary activity, since there are antecedents of the practice of it there far away in time, around the year 3,800 B.C. in Asia, to be more precise. Such a situation can even be verified as a consequence of the existence of laws of that time that punished the theft of species.
There are also many references to its practice in the heyday of the Greeks and Romans.
Meanwhile, towards the century XVIII breakthroughs would occur as a result of discoveries in the field of artificial fertilization of salmon and trout
Although there are different techniques and technologies to apply to this activity, it does not require too many demands if you want to do it without too many devices. They can be carried out on sandy seabed or on special structures supported on the seabed. On them it is sown, and with respect to feeding it will be done by natural means.
However, it is also feasible to carry out aquaculture in a more controlled and technological way so that production is much higher.
