The name Aquaponics is a portmanteau word.
From Aquaculture and Hydroponics.
In 1985 McMurtry and Sanders developed a commercial aquaponic system with the name " - Integrated Aqua Vegeculture System - "., which processes the fish excretions from tilapia cichlids by filtering them through algae and bacteria on sand filters for growing tomato plants.
This basic research begun by McMurtry and Sanders was developed by the University of Virgin Island in a special research program for aquaculture - aquaponics. There are now aquaponics systems ranging from small systems to large commercial production plants. They can be found all over the world and are used both in industrialized and in developing countries. In aquaponic systems the water must not be exchanged or additionally filtered, since it is refed into the cycle through the described biological treatment processes and made available again for fish farming in the required quality. Thus , the ecological problem of the eutrophication of natural waters due to the unregulated disposal of waste water from aquaculture does not occur.
Fresh water must be supplied only for losses due to absorption by the plants or the removal of biomass from the system.
"Willst du für ein Jahr vorausplanen, so pflanze Reis. Willst du für ein Jahrzehnt vorausplanen, so pflanze Bäume. Willst du für ein Jahrhundert planen, so bilde Menschen." "Do you want to make a plan for a year, plant rice. Do you want to make a plan for a decade, plant trees. Do you want to make a plan for a century, educate people."
(Zhuang Zi 369-270 v.Chr.)
