Aquaponics is the a growing technique that combines elements of aquaculture (raising aquatic animals such as snails, fish, crayfish or prawns) and hydroponics (growing plants in water and without soil) together in one integrated system. Aquaponics can be used to generate revenue by selling produce to tourists. This can also be a means of reducing dependencies on food importation. Aquaponics offers the ability to turn waste into a resource. This has a lot of potential towards promoting self-sustainable agriculture. Aquaponic Gardening enables home fish farming. You can now feel good about eating fish again. Aquaponic Gardening uses 90% less water than soil-based gardening because the water is re-circulated and only that which the plants take up or evaporates is ever replaced.
Aquaponic systems recirculate and reuse water very effectively. The system relies on the relationship between the animals and the plants to maintain a stable aquatic environment that experience a minimum of fluctuation in ambient nutrient and oxygen levels. Aquaponic systems can also be used to replicate controlled wetland conditions. Constructed wetlands can be useful for biofiltration and treatment of typical household sewage. Aquaponic systems can also be utilized to produce organic vegetables and herbs, and provide indoor decor at the same time. These systems can serve as a source of herbs and vegetables indoors.
Aquaponics has also been used as a sustainable, environmentally-friendly method of filtering the water of a polluted lake. So, not just farming can benefit from aquaponics! With a little bit of creative thought, aquaponics and other sustainable farming methods can help with many of today's problems.
