Aquaponics is a system that re-circulates both aquaculture and hydroponic vegetables, flowers and herbs. Aquaculture is the growing of fishes in a re-circulating system, while hydroponics is the growing of plants without soil.
In Aquaponics, nutrient-rich water from the fish tank are pumped into the vegetable growbed. Water will then trickle through the growbed and back into the fish tank.
During this process, plants extract the water and nutrients they need for growing, hence cleaning the water for the fishes. Bacteria that live on the surface of the growbed and on the gravels placed in the fish tank convert ammonia waste from the fish into nitrates that is useful for the plants. This process is termed the Nitrogen Cycle.
Research has shown that Aquaponics uses 90% less water as compared to traditional vegetable farming. Furthermore, Aquaponics not only produce vegetables, breeding of fishes can also be done through this process!
Aquaponics is an interesting concept that has not been extensively tested in Singapore. A wide range of educational knowledge can be gained through learning Aquaponics with us, such as:
- Learning the life cycle of plants and fishes
- Educating our children on eco-friendly messages and encouraging water conservation
- A strong understanding of the co-relationships between plants and animals
- Reduce, reuse and recycle
- Nurturing caring hearts
Here at Ecoponics, we offer Aquaponics Science Classes to Students from Primary and Secondary Schools in Singapore. As Singaporeans do not have the luxury of having a lot of interactions with farm life, using a aquaponics system allows them to better understand how they can get their food, even in the concrete city of Singapore.
Students have given us feedback that they enjoyed the classes a lot and were very interested in both the growing of vegetables and the rearing of fishes in the same ecosystem. Some children even wanted to purchase the aquaponics kits!
