A valuable yet often discarded and unused by-product of aquaculture is the manure generated by the fish. What many traditional fish farm operations have considered to be “waste” we consider to be a valuable nutrient resource that most be put to beneficial use if we are to truly emulate the process of nature. There are numerous methods to achieve beneficial usages for this nutrient source one is: Aquaponics – A tried and Proven Method.
Aquaponics is a farming method that populations around the world—notably the Aztec civilization and people throughout Asia with rice paddies—have used for thousands of years. Aquaponics systems grow fish and produce in a single system. The fish are fed an outside source of food and produce waste. These wastes then provide the essential nutrients that allow the plants to grow.
Aquaponics realizes several important benefits over dry-land agriculture, including reduced energy, 95% less water consumption and a more efficient operating model.
The traditional agriculture industry uses vast amounts of water resources—food production consumes more than 70% of global freshwater sources. In addition, farming tends to be energy intensive and requires constant labor over great swaths of land.
In addition to offering the benefits of reduced energy use and improved crop output, aquaponics yields many community benefits, including: Better nutrition options in underprivileged communities: urban environments that are known as “food deserts” could greatly benefit from locally grown produce; communities in remote and/or infertile land areas could access fresh produce and protein.
