Binding of hydroponics and aquaculture systems in the sixties of the twentieth century coined by fusion, the term aquaponics being its main drivers researchers William Mc Larney and Ronald D. Zweig. Since then there have been major advances mainly in Australia that currently can be considered the pioneer in the combined techniques of aquaponics.
The system is based on the use, by crop plants, organic waste generated by fish. Using a closed circulation of water, it passes from the tank housing the fish horticultural cultivation trays and returned, clean oxygenated, the vessel containing the fish.
Advantages of Aquaponics
The aquaponic system performance, elapsed stabilization phase (4 to 6 weeks), exceeds exclusively hydroponic systems and far superior to traditional cultivation substrate or soil.
1. Once stabilized, has outperformed hydroponics and traditional agriculture provides.
2. No residual contamination and water consumption, compared with other types of agriculture is minimal due to the recirculation system. Just replace that lost by evaporation.
3. Not required in hydroponic nutrient solutions or expensive as fertilizer as in conventional agriculture. Depending on the composition of the water in the area, just add some trace elements (iron, calcium and potassium) since the system does not generate autonomously in sufficient quantities.
4. Fish produced are healthier than those kept in typical aquaculture production volume is higher. It is not necessary to cover residues in fish and other aquaculture procedures are expelled or sea or freshwater courses avoiding eutrophication (excess of organic matter in the middle).
5. In the same area are produced vegetables and fish for optimal quality. 6. High resistance to pests and diseases can also be treated through Integrated and non-pesticide.
