properly managed Aquaponics system

In Aquaponics, the sole source of plant nutrients is fish waste. As unbelievable as this may seem, with a properly managed Aquaponics system, plants can thrive on this source of nitrogen. The key is to have a healthy bacterial colony growing in the system, which will convert the toxic fish waste into harmless nitrates which are an excellent fertilizer for the plants. The bulk of the bacterial colonies will be in the grow bed medium, often gravel.

In a newly set-up Aquaponics system, the bacteria will need some time to colonize the medium. This is why a process called ‘cycling’ is used. There are two methods of cycling your system – using fish right from the start or putting the fish in only when the bacteria have established themselves. The first method takes 4 to 6 weeks, while the latter is quicker and can be done in about 10 days. Cycling without fish (using ammonia) is also safer.

An important aspect in the system that is needed to ensure a steady supply of plant nutrients is pH. If this is not optimal, an accumulation of toxic materials will build up, and nutrient generation by the bacteria will be halted. In addition, pH outside the range will make it harder for the plant roots to take up nutrients and can harm the fish. Try to keep your pH at around 6.7 to 7. If your pH is outside the range, get commercial pH regulators to increase or decrease the pH. Alternatively use vinegar to lower the pH and calcium carbonate or baking soda to increase the pH.

Although some Aquaponics farmers use nutrient supplements, in a properly managed system supplements are never required. In addition, if you use supplements you need to be very careful, as some can harm the fish. As long as you keep the pH at 6.7 to 7, and the water well oxygenated, the bacteria will provide more than enough nutrients for your plants.

The only substance that it may be beneficial to add is salt. Salt is often added to Aquaponics systems at 1 to 2 ppt (parts per thousand; meaning 1 kilo to 1000 liters of water). Adding salt increases the resistance of the fish to disease and infections, because it has a positive effect on the mucus layer of the fish. If you decide to add salt, it is important to keep the concentration below 2ppt and to use pure sea salt – not table salt.

Feeding your aquaponics fish

Feeding your aquaponics fish is one of your daily tasks when running an Aquaponics system. It is vital for the fish and in turn essential for the production of plant nutrients. In this article we’ll talk about the what, when and how to feed your fish. We’ll also talk about using auto-feeders for the ones among you who like to automate life!

Most fish are not picky on feeding schedule; indeed in the wild there is no such thing as regular feeding. They will adjust their metabolisms and growth rates according to food availability. So if you want to grow fish quickly, simply feed them often. However, be careful with crowding because a population density which is too high will make the fish labile to disease outbreaks. With regards to the actual amounts of feed per feeding session, you should give them as much feed as they can eat within five minutes.

Many automatic feeders are available, differing in complexity and price. However, you can get simple cheap ones which will do the job just fine. You should set the feeding times at once or twice daily, possibly more if you want to grow fish quickly and have a low stocking density. Using an automatic feeder does not mean that you can stop checking on you system daily, because if you do, you won’t know if anything goes wrong with the system.

With regards to the actual feed, most people opt for commercial feed, which is an excellent choice. Commercial fee is either of the omnivorous or carnivorous type and these will differ in their quantities of protein. Check with your local fisheries department for the most suitable one for the particular fish species you are growing; though most fish thrive well on both. Feed also comes in different pellet sizes – you should get the small ones for young fish and larger ones as the fish grow bigger.

Many Aquaponics farmers grow their own fish feed to drastically cut costs. The most commonly grown of such feeds is duckweed, a fast growing plant that is rich in protein. You can grow this in a separate tank or pond. To provide more protein, you can also grow worms and black soldier fly larvae. You can also feed your fish some garden scraps. For example, most omnivorous fish will enjoy bland-tasting plants and vegetable, such as lettuce. Be careful that the plant-food you give to the fish is not covered in pesticides or other harmful chemicals.

Good Reasons to Try Home Aquaponics

What is Home Aquaponics

Aquaponics is a fairly new form of farming which has arisen through a combination of aquaculture and hydroponics. Aquaculture being the rearing of fish in an artificial environment such as tanks or man made lakes or dams purely for consumption. Hydroponics of course is the growing of plants in a soil free environment where the nutrients are usually fed to the plant through the roots via a nutrient rich solution and can be grown either indoors or out. Hydroponics can be used to grow vegetables or flowers. Aquaponics uses the principle of feeding the fish, which in turn through their waste products feed the vegetables which makes them grow resulting in both fresh fish and vegetables for your table.

Why Home Aquaponics?

There are numerous reasons why aquaponics makes so much sense today. With the prices of meat, groceries and petrol all going up it just seems like we would all want to grow our own food organically right at home happy in the knowledge of what has gone into it. But is it all too hard?

Most of the components required for home aquaponics are very easy to get. Poly tanks, piping and pumps can all be sourced quite easily from hardware stores. Vegetable seedlings are available at all nurseries and fingerlings ( baby fish ) can be sourced from specialty fish outlets specifically for use in aquaponics. All that is required now is a little area at home, some water and the right guide book or education which you can find a link to at the end of this article to get you started.

The Benefits of Home Aquaponics

Firstly there is the satisfaction that you have grown your own fish and vegetables at home. You know exactly what went into them so you can be sure they are fresh and organic.

The benefit of aquaponics versus hydroponics is that because hydroponic plants are fed a nutrient solution, the end product can taste a little chemically. With aquaponics the vegetables are fed on the organic fish waste so it is all natural and really tastes it.

It really is an easy system of farming to maintain Keep the water right and the fish healthy and fed and the rest should just look after itself.

Besides the obvious benefits of aquaponics being fish and vegetables, as it is still a fairly new style of farming, there could also be a lot of upside in the business sense. Depending on the scale to which you want to take your aquaponics, you may create a market to sell your aquaponics fish and vegetables to. Along with that, you may develop the skills to promote, supply and install home aquaponics systems to others in your area. Once systems are installed no doubt there is a need for further education to newer users of home aquaponics so you could tutor in the subject. Who knows, you may even be trusted with the upkeep of others already established home aquaponics systems.

So whatever your reason for getting interested in home aquaponics, healthy food for you and others, educating others on an environmentally sound method of farming or setting up your very own thriving home aquaponics business, it certainly makes sense.

Aquaponics For Profit

Many people start this venture as a hobby, and quickly turn to doing aquaponics for profit, because they immediately realize how profitable it can be! It can be set up with minimum start up costs, and running costs are very low. With its unique set up, the system practically runs itself, as the plants and fish form a symbiotic relationship with the help of bacteria; the latter turn fish waste into plant nutrients, cleaning the water for the fish and providing fertilizer for the plants.

Aquaponics is rapidly gaining popularity because of the rising prices of food and the increasing demand for organic food (which is what you’ll be growing with an aquaponics system). Running an Aquaponics for profit business has many advantages. It is ideal for those who do not have a lot of money to invest, as it requires minimum costs to set up and run. As the costs are low, the profit margin is very significant. Both organic vegetables and fish fetch very good prices!

Another advantage of an Aquaponics for profit business is that it requires minimal space – Aquaponics is in fact the most space-effective method of food production. Generally, a room or garage is more than enough to produce enough food to make a profit.

Aquaponics is also fairly flexible, in the sense that you can grow many different species of plants and fish. So you may grow different species at different times of the year according to demand and competition in your area. For example some people grow predominantly vegetables, while others opt to growing herbs. Of course, there is no reason why you can’t grow both! The same goes for fish; there are many species you can rear. In addition, instead of growing fish for food, some people grow goldfish and other aquarium fish species which then they sell to pet shops or directly to owners. With some aquarium fish species, the prices fetched can be much higher than the prices for most ‘food’ fish. To keep the costs down, you should choose fish which have temperature requirements that are similar to the average temperature in your area. This will save you from using electricity to heat the water.

Popular fish which are grown using aquaponics for profit include tilapia (mainly in warmer climates), trout (mainly in colder climates), catfish, koi, bluegill, smallmouth bass, and goldfish (to be sold as pets). Make sure to check your state laws first, as there are some limitations on which fish can be grown. With regards to plants grown successfully in Aquaponics systems for profit, excellent examples include cucumbers, tomatoes, melons, strawberries, lettuce, spinach, peas, beans and squash; and herbs such as as rosemary and basil.

how to grow fish in an Aquaponics system

In aquaponics you will be growing vegetables and fish. Fish are a tasty food source of protein and omega 3 fatty acids – both essential for good health. Many people would think that it is extremely hard to grow fish in your own home or in your backyard, but with an aquaponics system this is not so. You will be able to grow lots of fish easily, all year round, and best of all cheaply! This is because you’ll be recycling the water and using the fish’s waste as a fertilizer for your vegetables. In turn, the vegetables will filter out the water for your fish, removing the need for expensive filtering equipment!

It is essential that you ensure the fish remain healthy, so that you can benefit from optimal yields of both fish and vegetables. When choosing which fish to grow, check that their optimal temperature is compatible with where you will be placing the set-up. If you are placing it in the garage, and it tends to get cold, then don’t get fish which require warm temperatures. In addition, fish require good levels of dissolved oxygen to thrive. Thankfully there are ways how to achieve this without using a pump; in other words, you can get aeration for free.

When choosing which fish to culture in an aquaponics system, make sure you check the relevant state laws, as there are legal limitations on the species of fish that can be purchased and grown.  There are many suitable fish for aquaculture, such as trout, tilapia, cod, perch and bass. Indeed, the final decision will be based on your personal preference.

Perhaps the most frequently grown fish in aquaponics systems is the tilapia, which is native to Israel. Tilapia are fast growing, reproduce quickly and are very resistant. Fluctuations in temperature, dissolved oxygen levels, pH and waste build-up do not have such an impact on tilapia as they do on other species of fish. They have been farmed for over 2,000 years, so there is no reason why you wouldn’t be successful with them!

The tilapia’s optimal temperature is about 26-32′C, although they can live at temperatures as low as 20′C. However, for fast growths and best quality, you should try to give them their optimal temperature.

Carp are another fish of choice for aquaponics systems, because like tilapia they grow quickly and are very hardy. They have also been farmed in Asia for over 2,000 years, and nowadays continue to be farmed in simple ponds. They are tasty, rich in protein and in heart-healthy omega 3 fatty acids.
