Aquaponics - Aquaculture Meets Hydroponic Farming
There
are a variety of methods used in aquaculture, but the system - by
definition - is a closed system. This in itself poses a problem - the
large amounts of water needed to successfully sustain a healthy colony
of aquatic life. When you grow commercial amounts of fish or other
aquatic species you must clean the water continuously due to the high
amounts of toxins given off by the waste of the crop.
Hydroponics itself poses problems of its own, namely the constant flow of water and addition of nutrients - a costly and time-consuming effort. Water must be constantly monitored for necessary supplementing with food and other components for plant health, and the constant, open circulation of water results in large amounts of evaporation of water that must be replaced continuously.
Enter Aquaponics and its benefits. If the fish needs clean water to survive, and the plants need constant nutrients, why not give each what it needs in a compatible, symbiotic relationship that, when balanced, becomes a complete ecosystem needing just a minimal amount of maintenance? That plan was put into place, and by aquponics we have the ever-expanding research of combining the two systems for the greater good, enabling more food to be grown in less space, and less water being used to grow it.

Urban Aquaponics Basic Components
There are three part components to the system:
Your Fish, The Plants You Grow, and The Hardware You Use To Build.
1. Fish
A variety of freshwater fish can and have been used for aquaponics systems,
including carp, goldfish, trout, smallmouth bass, largemouth bass, catfish, and
tilapia to name a few.
2. Plants
Based upon your decision surrounding your choice of fish, and the stage of their
maturity, you will now need to give thought to your plants.
The Ultimate Aquaponics Home System is a float based system, and you can
either start your seedlings already in the floats or you can transfer the shoots
from a seedling bed attached to the system (an option for which your plans here
allow) or from a conventional seedling tray.
3. Hardware
Schedule 40 PVC, Pump, Floats, lumber, and water treatment products.
Many of the hardware items can be purchased locally.
