** Basic principles of Aquaponics
Aquaponics refers to a multi-tiered system for sustainable food production. In other words, it is a bio-integrated system that combines hydroponics and recirculating aquaculture. Aquaponics is used as a model for ecological food production according to several basic principles: In other words, Aquaponics is a method of growing food without using soil. Instead, they use water to grow plants, which is a type of hydro-culture. Hydroponics is another type of Hydro-culture. Aquaponics uses Hydroponics as part of the overall aquaponics system. And also Aquaponics also uses a recirculating aquaculture system.

Some people refer to the use of hydroponics as fish or organic hydroculture as Aquaponics.

1.Waste in one biological system serves as a nutrient for a second biological system, which is facilitated by microbial activity.

2. Plant-to-plant integration increases diversity and results in multinutrient multicultures that produce multiple products.

3. Water is reused through biological filtration and recycling.

4. Local food production provides access to healthy food and improves local economies.

In a word, such aquaponic can be called a natural ecosystem. A microcosm called the nitrogen cycle is formed in the system that connects the fish tank and the flower bed where plants are grown, which continuously supplies nutrients to plants and clean water to fish. As shown in the figure below, the nitrogen cycle is formed naturally, not artificial, like hydroponic cultivation.
