How do we use aquaponics system in agriculture


Aquaponics is an agricultural system which uses fish, plants and water to create a symbiotic environment. The bacteria in the fish waste helps produce hydroponic nutrients for plant growth while excess plant food provides nourishment for the aquatic animals. Aquaponics systems work by using an aquarium to raise fish and plants together.

Aquaponics is a form of agriculture that combines raising fish in tanks (recirculating aquaculture) with soilless plant culture (hydroponics). In aquaponics, the nutrient-rich water from raising fish provides a natural fertilizer for the plants and the plants help to purify the water for the fish.


How many fish should I raise in my aquaponic system?

In a smaller sized tank, <50 gallons of water, we recommend stocking the tank with 1″ of fish for every 1 gallon of water. For example, a 10-gallon tank could hold 10x 1″ fish or 5x 2″ fish. For larger fish in tanks over 50 gallons, we recommend a stocking density of 1 lb of fish per 5 -10 gallons of water, or 1-2 fish per 10 gallons of water.

How many fish can I grow in an aquaponics system?

That’s it. Aquaponics uses less than a tenth the amount of water a comparable soil-based garden uses.

Why do aquaponics require no soil?

Because there is no soil to till, there is no longer a need to use tractors and gas-powered farm equipment. Commercial aquaponics operations typically employ either a raft method, where the plants float in water until they are harvested, or media. Neither requires the kind of labor that soil-based farming does.

How does agriculture waste water?

Modern agricultural methods waste an incredible amount of water. Water is either sprayed or flooded through fields where a huge amount either evaporates into the air on a hot day, or seeps past the plant roots and into the water table, pulling chemical fertilizers, herbicides and pesticides down with it.

What are the main pollutant sources for aquaponics?

The main pollutant sources are CO 2 emissions from all the petroleum being used in farm production and food transportation, methane from cattle production, and nitrous oxide from over-fertilizing. Aquaponics requires none of these inputs. Petroleum needs in aquaponics range from much less to zero.
