The term aquaculture comes from the Latin “aqua” means “water”, in Spanish culture. Aquaculture is made up of the methods and studies of cultivation of aquatic varieties such as plants and animals. Aquaculture is the main economic profession for the creation of food, which are raw materials for industrial and pharmacological use, and living organisms for crops and placement of ornaments to decorate a thing. Aquaculture is the cultivation method that can be practiced in fresh water and is generally described as having a low density of dilute salts and a complete low of dissolved solids, fresh water is located in the areas of the earth such as ice sheets, ice fields, glaciers, lagoons, lakes, rivers, lightning and under the ground as groundwater that are the enacuifers and streams as well as salt water.
Sea water is salty due to the density of diluted mineral salts that encompasses 35%, 3.5% or 35 g / l as a measure. The average capacity of the area is 1,025 g / ml, being more intense than fresh water and pure water. But from the most common cultures correspond Platonic organisms that is the main organisms of the microscopic ones that float in salty or fresh waters that are macroalgae, mollusks, crustaceans.
Aquaculture is classified by two different types, which is extensive aquaculture and semi-intensive and intensive aquaculture.
Extensive aquaculture, are the low-power and technological cultivation methods, they are also the best known because they are the marine filter specimens that are known as oysters, clams and mussels and those of marine macroalgae that run on the sandy bottoms of the surface intertidal or on the structures supported on the bottom, which are the stakes and tables of crops or floating, such as the trays and lines.
La acuicultura semitensiva e intensiva, es el procedimiento de cultivación mas controlado y que da mayor productividad, donde la ciencia y la participación es mucho mayor a los extensivos. En la cultivación de los peces lo meten en jaulas flotantes y los mantienen en el mar o en los lagos.
