What Is Aquaponics And How Does It Work?

Aquaponics is a sustainable and symbiotic approach to cultivating plants and fish together in a closed-loop system. It combines aquaculture (raising fish) with hydroponics (growing plants in water) to create an efficient and eco-friendly method of food production.

The symbiotic relationship between fish and plants:

  • Fish produce waste in the form of ammonia through their excretions.
  • Beneficial bacteria, known as nitrifying bacteria, convert the ammonia into nitrites and then nitrates.
  • Nitrates serve as a valuable nutrient source for plants, promoting their growth.
  • As the plants uptake the nitrates, they act as a natural filter, purifying the water for the fish.

Nutrient cycling in an aquaponics system:

  • Fish excrete ammonia-rich waste, which is toxic to them in high concentrations.
  • Nitrifying bacteria, specifically nitrosomonas and nitrobacter, convert ammonia into nitrites and then nitrates.
  • Plants absorb nitrates as their primary source of nutrients, removing them from the water.
  • By removing nitrates, plants effectively purify the water, creating a healthy environment for the fish.
  • Clean water is then recirculated back to the fish tanks, closing the loop and ensuring the sustainability of the system.

Benefits of aquaponics:

  • Efficient use of water: Aquaponics uses 90% less water compared to traditional soil-based farming.
  • No need for chemical fertilizers: The fish waste provides all the essential nutrients plants need to grow, eliminating the need for synthetic fertilizers.
