What is aquaponics and what are the benefits?
Aquaponics is a sustainable farming method that combines aquaculture, or raising fish in tanks, with hydroponics or growing plants in water. The system essentially creates an indoor ecosystem of water and plants. Aquaponics has many benefits, including reducing waste, improving food security, and reducing greenhouse gas emissions.
What is aquaponics?
Aquaponics is a big hope for sustainable organic crop production, aquaculture and water consumption. The fish waste is recycled and used for plant growth instead of throwing it in the ocean. The water is recirculated in a closed system lowering the consumption of this resource.
Why is aquaponics important?
Benefits of aquaponics: 1) Aquaponics is a way to grow your own fish and vegetables at the same time. You feed the fish and the fish will feed your plants through their waste output. 2) There is no need to use fertilizers because the fish provide rich nutrients for the plants.
Why do fish die in aquaponics?
A too alkaline or too acidic pH is one of the main reasons fish or plants die, leading to gardening failure. The pH adjusters need to be specially designed for this type of growing system, otherwise, they could harm the fish. You can find these adjusters in a local aquaponic gardening supplier.

How much water does aquaponics use?
Research has shown that aquaponic gardens use 1/10th of the water you would use for soil garden. 4) Regular gardening pesticides or other chemicals can’t be used because they would harm the fish. 5) This results in healthier and organic vegetables.
How to make an aquaponics system?
1) You can make your own aquaponics system and here is a simple and complete guide you can use to make one. Start small see if it’s good for you then feel free to go bigger.#N#2) Have set a different power source as a backup. It’s vital to keep the water flowing and the oxygen pumps on.#N#3) Make sure you feed the fish enough and let them thrive . Depletion of fish stock makes this type of cultivation impossible.#N#4) Keep food input constant for the fish and that will result in regular fish waste you can use to feed your plants.#N#5) Ensure your plants and fish with good aeration. Not only the plants need their roots to be oxygenated, but also, the fish and the bacteria need the water to be oxygenated. As the fish grow bigger, their oxygen needs increases and you might need to adjust accordingly.#N#6) When you decide what plants you want to grow, pick the ones that have similar water condition needs as the fish, and you will have greater success.#N#7) Remove some excess fish waste when necessary. Too much can harm the health of the fish.#N#8) Keep an eye on the level of pH because as shown above, it is crucial for the garden.#N#9) Fish tanks should be made of glass or food grade plastic.#N#10) Avoid using any pesticide other than organic, or any other substances that can and will harm the fish or the good bacteria (vinegar, citric and/or hydrochloric acid).
What is the best fish for aquaculture?
Fish are the ones feeding your plants. The fish used in this type of aquaculture are freshwater fish, most popular being tilapia and barramundi because they tolerate better diverse water conditions and they grow fast. Trout can also be used especially for lower water temperatures.
What is aquaponics in science?
What is Aquaponics? Many definitions of aquaponics recognize the ‘ponics’ part of this word for hydroponics which is growing plants in water with a soil-less media. Hydroponics is its own growing method with pros and cons (discussed later). Literally speaking, Aquaponics is putting fish to work.
How does aquaponics work?
Instead of using dirt or toxic chemical solutions to grow plants, aquaponics uses highly nutritious fish effluent that contains all the required nutrients for optimum plant growth. Instead of discharging water, aquaponics uses the plants, naturally occurring bacteria, and the media in which they grow in to clean and purify the water, after which it is returned to the fish tank. This water can be reused indefinitely and will only need to be topped-off when it is lost through transpiration from the plants and evaporation.
How much water does aquaponics use?
Aquaponics uses 1/10th of the water of soil-based gardening and even less water than hydroponics or recirculating aquaculture. No harmful petrochemicals, pesticides or herbicides can be used. It’s a natural ecosystem. Gardening chores are cut down dramatically or eliminated.
What happens if you use pesticides on fish?
If pesticides are applied to the plants, the fish will suffer. Conversely, if growth hormones or antibiotics are given to the fish, the plants will suffer. Aquaponics is the management of a full ecosystem, so one input will inevitably interact with everything in the system.
What is vertical aquaponics?
Vertical Aquaponics One of the greatest aspects of aquaponics is its ability to grow an incredible amount of food in a very small area. No method does this better than vertical aquaponics. Plants are stacked on top of each other in tower systems such as the AquaVertica. Water flows in through the top of the tower, and flows through a wicking material that the plants roots absorb water and nutrients from. The water then falls into a trough or directly into the fish tank. This form of agriculture makes the most of each square foot of space, and works very well with leafy greens, strawberries, and other crops that do not require support to grow.
What is hydroponics system?
Traditional hydroponic systems rely on the careful application of expensive, man-made nutrients made from mixing together a concoction of chemicals, salts and trace elements. In aquaponics, you merely feed your fish inexpensive fish feed, food scraps, and food you grow yourself.
What is media based aquaponics?
Media-based Aquaponics Media growing involves growing plants in inert planting media such as expanded clay pellets or shale.
How does The Aquaponics System Work?
Vegetables clean the water that returns to the fish. Microbes, along with fish. And their droppings, play an important role in plant nutrition.
What is Botanical and Fish Farming?
The flexible farming regimen that provides the most wellness and nutrition. Aquaponics is a type of agriculture that combines aquaculture. And fish recycling in ponds with growing plants without hydroponics in the soil.
Why is aquaponics important?
Another advantage of aquaponics is that plants can be grown in very small spaces and tend to grow fast thanks to the extra nutritious substances from the fish waste. You can also control the temperature environment easier than in traditional soil farming.
How does aquaponics work?
Water from the fish tank is recirculated through the system and across the grow beds full of plants, which absorb the dissolved nutrients in the water. Aquaponics mimics the natural aquatic ecosystems found in rivers, streams, and other bodies of water, creating a symbiotic relationship between plant and animal that benefits both equally.
What are the factors that affect tilapia?
Factors like temperatures, pH, and nutrient levels must be balanced between the plants and the animals to be successful. Most systems use tilapia, since they can adapt to a range of environments, withstand different water conditions, and are easy to breed.
How does vertical aquaponics work?
As the name suggests, vertical aquaponics stacks plants on top of one another in a tower. Water flows from the top through a wicking material to provide the plant's roots with nutrients before falling into a lower trough or fish tank directly under the system. It’s another space-saving method, and it allows growers to produce a larger amount of food with relatively small square footage.
What is the use of growth media in aquaponics?
In aquaponics, the growing media also serves as a surface for good bacteria to thrive within the grow bed and help filter the waste expelled by the fish tank. Expanded clay pebbles are a lightweight aggregate ...
How does a water pump work?
A pump will draw the water from the tank, passing it through the media bed to let the plants draw nutrients from the water, before returning it back to the tank fully filtered. Most home and hobby scale systems are based on media aquaponics, as well as larger-scale operations of fruiting plants, leafy greens, and herbs.
What fish can I use for aquaponics?
What Fish to Use for Aquaponics? Tilapia is the most common fish species used in aquaponics and is the perfect starter fish for novices, but growers can also use trout, catfish, bass, and even crustaceans, goldfish, or ornamental koi.
Why is aquaponics important?
The fish food we use in aquaponics is very important. Indeed, this is the source of food for the whole ecosystem. It is possible to produce your own fish food. However, most of us use aquaculture fish food because it is very convenient.
How does aquaponics work?
Fish are living in a fish tank. when we feed the fish, they digest the food and reject organic waste into the water. A water pump pushes the fish waste into a grow-bed full of bacteria. The bacteria are not only consuming the fish waste but also reject plant nutrients.
What are the advantages of flood and drain aquaponics?
Advantages of a flood and drain aquaponics: It is the aquaponics system that represents the best a natural ecosystem. After few months, a whole ecosystem is in place and the media looks very much like a soil. It is well adapted to small backyards.
What is a fish tank?
A fish tank supplies water to a serie of mechanical and biological filters. then, the water enters into a “ Deep Water Culture ” tank. The DWC tank consist of plants growing on rafts floating on top of a tank (generally more than 30 cm deep). In the bottom of the DWC tank some air stones supply a constant flow of air.
How much food can aquaponics produce?
But in this article I will give you an average estimation. Two square meters of aquaponics system (flood and drain aquaponics) can produce 6 kg of fish and 40 kg of plants every year.
What was the origin of aquaponics?
At his origin, aquaponics was mainly “extensive”. Fish were grown at very low density with natural occurring food. Then pioneers tried to apply this technique to more “ controlled environments “. They were inspired by the progress of the recirculated water systems in aquaculture.
How many tanks are in a flood and drain aquaponics system?
The flood and drain aquaponics consist of minimum 2 tanks. A fish tank at the base and a grow-bed on top. The fish tank water (charged in fish waste) goes through a water pump and arrives to the grow-bed. The grow-bed is actually a “ flood and drain grow-bed “. Yes, it f lows and drain several time per hour.

Aquaponics is a combination of aquaculture and hydroponics to grow plants without soil. Let’s first do a quick overview of hydroponics.
What are the Benefits of Aquaponics?
For the home grower, this indoor agriculture method of producing fresh organic vegetables using the perfect collaboration in which microbes perform a conversion of ammonia from fish waste into the perfect nitrate based fertilizer, has many advantages.
What Plants and Vegetables Can You Grow in Aquaponics Systems?
Many types of plants, vegetables, fruits, and herbs can be grown in aquaponics, but before deciding what to grow, there are a few factors to consider. Factors include:
How do plants keep freshwater fish healthy?
To complete this symbiotic combination, the plants keep the water healthy for the freshwater fish by “cleaning” the tank of waste as they draw the nutrients from the water.
What is the waste product of an aquatic animal?
The waste products of the aquatic animals in the tank are nutrient providers for the plants. When balanced correctly, this is a complete self-sustaining ecosystem, in which waste from fish farming methods become the source of rich nutrients for plants.
Where did aquaponics originate?
Forms of aquaponics can be traced back to the Aztec Indians, who were known to have raised plants on rafts over a millennium ago. Aquaponic and hydroponic systems, as we currently think of them, are a relatively recent form of agriculture that originated in the past 50 years.
How to keep plants healthy?
Make sure the water has plenty of aeration. Fish, bacteria, and plants roots all require plenty of oxygen to maintain a healthy system. Provide plenty of fish food. Fish that thrive in their environment will help the plants do the same.
How Does It Work?
When you combine aquaculture with hydroponics, you get a manageable and less expensive fish and plant cultivation system. Aquaponic farming is gaining more popularity nowadays since it is far more scalable than the rest and can be done outdoors as well as indoors.
The Benefits of Aquaponics
Aquaponics is a relatively new word in indoor gardening. However, it has been practised under several other names throughout the world for decades. It is mainly because this food production system comes with a plethora of benefits. Mentioned below are some of them.

Aquaponics Compared to Hydroponics
The difference between hydroponics and aquaponics is that aquaponics uses fish to provide nutrients, and hydroponics uses formulated solutions.
What is Aquaponics?
Simply put, aquaponics is the combination of two food production systems; aquaculture, the growing of fish, and hydroponics, the growing of plants in a soil-less medium using nutrient rich-water.
Aquaponic Nitrogen Cycle
The first lot of bacteria that get to work are predominantly from the Nitrosomonas genus. They get their energy by oxidising the ammonia (NH4) the fish produce into nitrite (NO2).
