Aquaponic Gardening is the next major trend in sustainable living and urban agriculture. It combines the already used areas of hydroponic gardening and aquaculture to create a food and fish growth system that is economically viable and works on any scale. Backyard Aquaponics is a growing movement that has been gaining popularity in Europe and North America as people look for ways to either supplement their income or bolster their family food supply in "Today(TM)s" difficult economic climate.
Hydroponic gardening is the Practise of using water as the primary growth medium for plants, instead of soil. This requires a large growth tank to contain the water and a system for circulating the water through the system so that it reaches all of the plants. The water carries nutrients through the system which are added manually by the farmer. The best part of hydroponic gardening is the ability to maintain almost total control over the plant growth environment and the ability to accurately measure many variables that affect plant growth.
Growing plants in water has numerous advantages. It's good for the environment because it doesn't lead to soil erosion as normal farming does. It also allows the farmer to filter and purify the water as desired, and can help with rapid elimination of bacteria or other contaminants in case any sort of infestation occurs. Because nutrients dissolve uniformly in solution with the water, it's possible to consistently and accurately measure nutrient levels in the soil which can help farmers maintain the right pH and chemical balances within the environment. This means that conditions for optimal growth can be maintained for long periods of time with little worry, and as a result, farmers produce more crops per year and yield a greater quantity of biomass compared with conventional farms.
Growing fish is also important in the "Aquaponics" system and there are several different popular fish. Tilapia are the most popular because they are easy to raise and very delicious. While other fish engage in cannibalism for population control when kept at high densities, Tilapia do not. They are also valuable commercially and cost little to raise in terms of dollars spent on food versus pounds of Tilapia produced. Population control for Tilapia is also a simple task, as the introduction of a predatory fish like a Barracuda can reduce numbers of infant Tilapia and leave more food for the larger and more lucrative fish in the tank.
