Aquaponics is a very exciting new and easy way to grow your own fresh and healthy organic vegetables without all of the messy hard work of a regular garden.

This fun new simple growing method produces up to 10 times more organic produce in half the time of a conventional garden.

The beauty of this system is that it is completely scaleable, so that you can create an aquaponics system that is as big or small as you desire.

Aquaponics, sometimes written as aqua ponics, is the science of producing sustainable food combining traditional aquaculture with hydroponics in a mutually beneficial environment, which will be discussed in this aquaponics how to article. To understand aquaponics it is important to know the meaning of the two subsystems involved. Aquaculture is the raising of aquatic animals such as fish, prawns, crayfish, etc. in tanks. Hydroponics involves cultivating plants in water.

These two systems are merged together to form a unique environment that leads to a synergetic relationship between animals and plants. There are evidences of aquaponic gardening in the Aztec civilization, where plants were grown on island like structures filled with waste materials from canals.

Oriental countries like China and Thailand have been using similar aquaponic plans for generations. Their paddy fields grow fish. Scientists and farmers all around the world have realized the advantages of these poly-cultural farming methods and are employing them vigorously.

Aquaponics how to make it work

The merging of two subsystems results in the creation of a favorable growth setting with minimum fluctuation in ambient nutrient and oxygen levels with heightened productivity.

Hydroponic systems depend on the usage of man-made nutrients for the ideal growth of plants. These nutrients are a precise combination of different chemicals, salts and other elements, which creates the optimal balance. The water built up in this system needs to be drained off periodically because the salts and chemicals react to produce toxic products for the plants.

On the other hand, aquaculture involves a large quantity of fish in comparatively small amount of water. These high stocking rates and closed circulation system often lead to the pollution of the tank with high concentrations of ammonia. Again, water has to be drained from the tank at least once each day.

Aquaponics combines these two systems to its advantage. It uses the plants and the means in which they grow to detoxify and purify the fish effluent water from the fish tanks and after purification the water is brought back to the fish tank. The water from the fish tanks is in turn highly nutritious for the optimum growth of the plants. Therefore, nothing is wasted, the water from each system can be reused and only requires a small amount of fresh water to be added periodically, to compensate for the loss of water due evaporation.

Aquaponics System
The plants are grown in this system with the roots submerged in the nutritious water from the fish tank, which facilitates the filtering of the toxic ammonia. When the water passes through this aquaponics system, it is detoxified and oxygenated enough to return back to the aquaculture containers. This is a continuous cycle. Some common applications of the aquaponics systems are:

• Deep-water aquaponics system: which is basically Styrofoam rafts that float on the water in deeper aquaculture troughs
• Recirculating aquaponics system: with solid media such as gravel, or clay beds in containers filled with water from aquaculture.
• Reciprocating aquaponics system: here the solid media container is intermittently flooded and drained.
• Other systems have top fed towers with nutrient-film channels. The PVC pipes are fitted with holes for pots or barrels, which are then filled with either gravel or rafts.

The aquaponics system grows most green leafy vegetables, but the most profitable varieties are Chinese cabbage, lettuce, tomatoes, okra, cantaloupe and bell peppers. Other types of vegetables that flourish in an aquaponics how to system include onions, taro, beans, kohlrabi, watercress, peas, turnips, parsnips, radishes, strawberries, melons, sweet potato and herbs.

Since the quantity of minerals and nutrients vary according to the different stages of growth of the plants, their harvesting is spread out; seedlings are grown at the same time as developing plants. This safeguards the stability of the amount of nutrient in the water due to the continuous symbiotic relationship, which cleanses impurities from the water.

Aquaponics System
Freshwater fish are the species most commonly raised in this system. But fish like crayfish and prawns are also grown. Tilapia is a favorite choice for both domestic and marketable projects that aim at raising edible fish. Some of the other varieties are barramundi, Silver Perch, or Eel-tailed catfish, Jade perch and Murray cod.

For moderate climates where it is difficult to maintain the water temperature the production of bluegill and catfish are suitable for domestic or non-commercial systems. Inedible aquaculture subsystems typically use fish species like Koi and goldfish.

Aquaponics System Advantages
Some of the unique benefits of this system are:

• Constant conservation of water
• Organic fertilization of plants with natural products like fish effluent
• Elimination of solid waste disposal from aquaculture
• Reduction in solid land for crop production
• Reduction of environmental footprint
• Reduction of pathogens

Aquaponics how to do it yourself

There are some deterrents that may discourage you from creating your own backyard Aquaponics system. Most of the aquaponics system design depends heavily on man-made energy, technological solutions, and constant environmental monitoring; the initial investment in infrastructure is also worth considering. Therefore, the aquaponics system plans have to be highly efficient, maximizing energy conservation and minimizing risks. Once you have acquired the necessary aquaponic supplies and the right Aquaponics plans, getting involved in DIY aquaponics will surely yield fruitful results.

There are several aquaponics forum that can guide you in the process. Some great aquaponics starter kits are also available in the market that can help you set up a very basic system with inexpensive supplies and provide you with the needed experience and confidence to initiate a bigger and more complex project.

The three main components of this practice are water, food given to the fish, and energy to force water between the two subsystems. There are several products available to ensure the successful functioning of these systems. Some of the supplies needed for a basic home aquaponics project include:

• Rootcubes, which are specially designed foam for hydroponics subsystems.
• Netpots, with plastic mesh around the edges and across the bottom.
• Hydrokorrels, these are kiln-fired clay pebbled with favorable pH values.
• Plant starter nutrients.
• High protein fish foods, which promote rapid growth in fish.
• Plumbing parts, such as bulkhead fittings, etc.
• And finally, aquaponics aeration systems, which could include tank, aerator, tube diffuser, etc.

Before initiating an aquaponics project make sure that the size of the aquaponic fish tank is right for the desired fish species and relevant to the space. The selection of the correct water pump and filtration system is vital as it should be able to maintain the stability of the nutrient and oxygen levels.

A more complex system design will require more maintenance time. Some people prefer using recycled materials to build the structure for their projects as they are cheaper but in such cases make sure to check the previous contents of the containers.

The benefits and profitable outcomes of an aquaponics how to system can definitely outweigh the constraints. When managed efficiently, an aquaponics system can persistently yield produce. This could be the vegetables grown in the hydroponics subsystem, and edible fish and other aquatic species bred in an aquaculture subsystem.

What To Consider When Making Your Aquaponics Plans

A lot of consideration goes into making aquaponics plans. As you start up this very rewarding venture you need to think about your purpose. You need to decide if you want to do this so that you can have a supply of fresh vegetables and fish for use in your home. Maybe you want to get into the business of supplying supermarkets or restaurants with fish and fresh vegetables. Which way you want to go will determine the kind of aquaponic system you use, as well as the fish and plants you will grow.

Aquaponics Plans

To set up an aquaponics system you may require a large area. It depends on your purpose for setting it up. You could have a small unit on your patio or in your backyard, or you could have a large commercial unit on your farm. So consider the following systems and which would best serve your purpose.

1.  Gravity Feed System
The fish tank is constructed in such a way that there is a drain at the bottom. Fish waste is able to collect at the bottom of the tank. The water is periodically pumped to the grow beds, together with the waste that has settled. One end of the grow beds will be slightly elevated so the water will flow to the lower end, like it would on a hill. The water, less waste, is now purified and drains back into the fish tank.

You can use a sump waste collector. A well-illustrated aquaponics diagram would show a pipe directing the water to the grow beds and another leading the waste away in a different direction. You can remove the waste separately to avoid the possibility of it collecting and blocking the water holes. The water would be pumped to the grow beds separately.

2.  Constant Flow System
In this system, water is allowed into the grow beds to a certain depth (mostly 12 inches). The roots of the plants extend directly into the water. Water is then pumped continuously to and from the fish tank. In this system the plants will have to be secured to withstand the moving water.

 3.  Drip System
This works almost the same way that irrigation does in gardening or farming. Water from the fish tanks is pumped to manifolds that are right next to the plants. Small holes are drilled into the manifolds. You can insert small tubes into these holes if you choose to and put the ends of these tubes into the growth medium. Some aquaponics kits come complete, saving you the need to do any drilling. They also come with aquaponics how to guides detailing how you should set them up.

Each of these systems must be cleaned regularly. Clogged or dirty filters could hamper the efficient running of your aquaponics system. Blocked pipes can stop the flow of water, which is essential for your system.

Commercial Aquaponics

Getting into commercial aquaponics is very profitable. It allows you to get fresh produce for your customers. The beauty of the system is that no fertilizers are used. You control what goes into the water, which can be as strict or diverse a diet as you think is necessary. You will be able to provide organic produce, something a lot of customers are leaning towards.

Aquaponic system plans give you the added advantage of making the most use of your land. Most commercial aquaponics systems include a greenhouse. The greenhouse allows you to control the environment that you grow your produce in. You can heat it up during winter or cool it down when temperatures get too high outside. This means your output is independent of seasons; you can harvest as often as is demanded.

You could choose to have an automated system. It is possible to get auto-feeders that release food at particular times. Adding this to your aquaponics plans could help you cut down on labor costs and increase your bottom line. You will however need to hire help to help you with the harvesting.

Where To Get Supplies Most agricultural stores stock fish food and most stock aquaponics supplies alongside all other livestock supplies. Look for a supplier near you.

What Kind Of Fish To Grow There are a number of aquaponics fish, which you can grow. You can grow edible fish as well as ornamental fish. The following are known to do well when reared in aquaponic systems:

1. Tilapia: They are hardy fish and can adjust to almost all kinds of conditions but only prefer warm water. They grow quickly and can get quite large. Are tasty as well.
2.  Yellow Perch: They eat almost anything, prefer cooler water and are a favorite with chefs. Their meat is flaky and delicious.
3.  Large mouth bass.
4.  Yellow perch
5.  Catfish
6.  Barramundi
7.  Angelfish
8.  Guppies
9.  Swordfish

The kind of fish you grow also determines the plants you grow. If you have aquaponics fish that survive in warm waters, you will need to grow plants that do well in warm temperatures. The system needs to be favorable to both the fish and the plants.

Aquaponics, sometimes written as aqua ponics, is the newest development in the agricultural industry. You can choose to do it in your own backyard or go commercial. There are various kinds of aquaponics systems at your disposal, as well as a variety of fish and plants that you can choose to grow. Just remember to do thorough research before you make your aquaponics plans.
