Definition - What does Backyard Aquaponics mean?
Aquaponics is a systematic, two-way cycle of aquaculture in which fish and other aquatic creatures produce waste that provides nutrition to hydroponically grown plants. The plants then filter the water in which the plants and animals live. Aquaponics combines aquaculture (aquatic animal farming) with hydroponics (the cultivation of plants using mineral nutrient solutions in water solvents instead of soil).
Specifically, backyard aquaponics is becoming a commonplace term in the aquaponics industry to refer to an aquaponics garden or set-up that is smaller than a commercial garden set-up. Most aquaponic systems are set up outdoors, so this term depicts a small, hobby-sized garden located on a residential property.
A backyard aquaponic garden or set-up can provide a household both with fresh fish and fresh produce, appealing to residents who wish to lead a more sustainable, self-sufficient lifestyle.
MaximumYield explains Backyard Aquaponics
Conventional aquaculture faces major toxicity problems, mainly due to the fact that the excretions from the aquatic animals can amass inside the water in which they are raised.
Aquaponics can be a solution to this as water from an aquaculture system is sent down to a hydroponic culture where the derivatives are decomposed by nitrifying bacteria primarily into nitrites, consequently into nitrates. The plant life takes nutrition from this and subsequently circulates the water back to the aquaculture structure.
As aquaponics is a relatively newer agricultural system, it is not so popular compared to conventional aquaculture and hydroponics. The exact date when it started is unknown. However, in 1979, the first large-scale aquaponics system was developed at the University of the Virgin Islands. The first major research on aquaponics was conducted in Alberta, Canada ,in the late 1990s.
