What is Aquaponics?


Aquaponics is a combination of aquaculture and hydroponics. Aquaculture is the practice of cultivating fish and other aquatic animals, and hydroponics is a system of growing plants without soil. Aquaponics combines these two practices to create an ecosystem in which the fish and plants thrive together.

In an aquaponic system, fish waste provides nutrients for the plants, and the plants filter the water for the fish. It’s a closed loop system that is very efficient and sustainable. This system is perfect for those who want to grow their own food while also conserving water and reducing waste.

How Do Freshwater Fish Feed Off Aquaponic Plants?

Freshwater Fish

When fish are raised in an aquaponic system, they produce waste that contains ammonia. Ammonia is toxic to fish, but it’s a great source of nitrogen for plants. The ammonia is converted into nitrates by bacteria that live in the growing medium of the plants. The nitrates are then taken up by the plants and used as food.

The plants in an aquaponic system grow much faster than in a traditional soil-based system. This is because they have a constant supply of nutrients and water. The plants also help to filter the water, removing harmful chemicals and bacteria. This creates a healthy environment for the fish.
