Introduction to Aquaponics
Kirk Gordon


Hydroponics and aquaponics are very similar in every way except
hydroponics requires the addition of fertilizer and there's no
fish in the nutrient solution.


In aquaponics, plants and fish live a symbiotic life with the
fish feeding the plants, and the plants cleaning and filtering
the fish's environment.


The fish waste becomes the plant's food source, consequently, the
plants' roots filter the water and keep the tank clean. In
essence, aquaponics could be considered a miniature ecosystem
because both plants and fish are thriving in the same
environment.


Aquaponics offer benefits to both Gardener's and Fish Farmers.
Fish Farmers may utilize aquaponics if they have difficulty
disposing the nutrient rich fish water, while hydroponics growers
benefit from having a constant supply of free plant food -
eliminating the need to purchase commercial fertilizers.


Unlike hydroponics or aeroponics, aquaponics is still a
relatively new cultivation technique. As more technology is
developed and the process is refined, it could potentially become
a space and money saving process for producing fish, vegetables
and herbs.


In hydroponics and aeroponics applications, the nutrient solution
needs to be prepared - measured, mixed, and then added to the
reservoir. In aquaponics, there's no mixing fertilizer involved,
making it a great way for beginners to cultivate plants. Only the
fish needs to be fed.

The number of commercial applications utilizing aeroponics is
still very limited. A number of universities globally are
currently exploring the science of aquaponics to advance this
extreme cultivation technique. Aquaponics is currently being used
in areas where the fish population is declining and/or their food
supply must be imported.
