What is Aquaponics?
AQUAPONICS IS AN INGENIOUS METHOD OF NATURAL FOOD PRODUCTION (fish & plant life) that Nature created and that you can now replicate at home…but on a much smaller scale of course.
The word Aquaponics is formed by the synthesizing of two words, aqua (water), and from the Greek ponos, or ponics (labor). When you combine the two, voila! Aquaponics. Simply put, ‘let the water do the work’ in a system that grows both fish and plants concurrently.
It is a natural process whereby the water containing the fish is pumped out and up into the plants above while the plants in turn, extract the nutrients, clean up the water, then return it to the fish tank in a seamless symbiotic relationship.
Here’s What You’ll Need to Get Started
You’ll need a fish tank or aquarium with a standard motorized pump, some PVC pipe and lights and of course, plants and fish. There may be a few more items but that’s the guts of it. We’ll get more into what kinds of fish and veggies are best to grow later in this article.
Whichever fish and plants you choose, the end result will be extremely healthy, pesticide-free vegetables and home-raised fish. This self-contained little eco system is naturally good for the environment as well. An added perk is that kids really love to interact with the entire process and they learn so much!
Oh, and you don’t have to live off the grid or be a Doomsday Prepper to enjoy this beautiful little system.
Which Aquaponic System is Best?
The concept is the same with them all. Your system choice should be based directly on what works best in your life style. Many systems are available for purchase on-line or if you’re the handyman type, with a few tools you can construct your own in an afternoon. A short list of available systems is laid out later in this article.
Aqua Facts: Aquaponics systems have been in use for thousands of years. The ancient Aztecs of Mexico made an entire city out of floating islands, and would grow squash and maize, raise cattle, and even live on the islands. Aquaponics have been used in the rice paddies of China and Thailand for centuries.
The Advantage of Aquaponics
Watering your garden–whether outdoor or hydroponically, requires a lot of water. However, with an Aquaponics system your water requirements never increase unless you expand the system.
Since there is already water circulating through the system, you only occasionally need to add a bit of water in order to accommodate for evaporation. Bottom line, the Aquaponics system can reduce your water usage by up to 90% over traditional gardening. For even less water usage you could go with a system like fogponics, but it's much harder to scale a system like that.
Using less water means fewer costs to run your garden. Rather than spending a small fortune watering your garden during the dry periods, you can keep the aquaponics system running all year long.
More Efficient Growth
The better nutrients the plants get, the more effectively they grow. The fish tank water is high quality plant food and the continual circulation will keep your plants growing beautifully.
Let’s not forget the harvest. With an Aquaponics system you’ll have larger plants in less time.
Grow Anytime, Anywhere
A bonus of the Aquaponics system is it’s highly versatile and can be used to grow fruits, veggies, herbs, and all kinds of flowers.
Weather or Not
An Aquaponics system is impervious to weather conditions. Outdoors you worry the weather could harm your plants but thanks to the design of the Aquaponics system, you will be able to grow your plants indoors year-round.
Your favorite veggies will be growing strong and healthy while outside plants may be burning up or being pummeled by rain or hail.
Another advantage of the Aquaponics system is there’s never any weeding or feeding to do. No plant-eating garden pests to deal with either.
In addition, an Aquaponics system is designed to be user-friendly and easy to operate. Not to mention, low-maintenance. Once the system is up and running, it basically runs itself.
TIP: Be sure to monitor the quality of your water each day and as with any aquarium, have a back up plan (a small generator) in case the power goes out and the air pumps quit working. The plants will be okay but the fish can’t live too long without oxygen.
An Easy Way to Grow Organic Food
We all know that many food products claiming to be organic aren’t always. I mean, how do you know for sure? Moreover, you can spend more on products claiming to be organic and get lower quality than regular vegetables grown using pesticides. The only way you can be sure that the food you are consuming is 100% organic and chemical-free is to grow it yourself.
Benefits of Growing Plants in Your Home
It is proven that having plants in a room has a positive effect on people’s moods. They also add color and oxygen to a room.
Aquaponics offers you the possibility to grow your own organic vegetables in your home while at the same time use them for decoration. This way you not only will enjoy the beauty of green plants in your home, but you will also save some money from having to purchase them.
Plants & Veggies from Aquaponics
You may wonder what type of vegetables you can grow using the Aquaponics system. Fruity vegetables like cucumbers, strawberries, tomatoes, squash, okra, pepper, melon; herbs like basil and oregano; different types of beans and peas as well as green leafy vegetables grow very well in this system. Plants whose fruits grow inside the ground however, like potatoes, sweet potatoes, onions, garlic and so on aren’t recommended for obvious reasons.
What will amaze you at harvest is the great taste your homegrown food will have. You will not believe that something so good can be grown in your garage or in your living room. If you want organic food make sure you purchase organic seeds so you know your harvests will be 100% organic.
The Best Fish for Aquaponics Systems
As to the fish, some people don’t raise fish to eat but merely to enjoy the beauty of them while also digging the low maintenance. If you plan on raising supper for some future night, figure on about 9 months from tank to skillet.
Choosing the Right Aquaponics Fish Species
There are a few things you need to take into account when choosing the species of fish for your garden:
- Temperature — How cold or hot does it get where you live? Some fish can’t handle the cold, and others hate the heat
- Home — Are you breeding them in a large fish tank, a DIY tank, or another type of system? Some fish don’t do well in certain environments
- Companions — A few fish are very anti-social, and they will often end up killing off other fish in the tank. You want to find a fish that can play nice with others!
- Grow Rate — The faster the fish grow, the faster you can eat them
- Hardiness —Do your homework to find a fish best suited for your needs and environment
Top Aquaponics Fish to Consider
The Tilapia is a survivor. Not only can it withstand poor water conditions, but is a fast-growing fish that reproduces quickly. They grow to be fairly large with a light and delicious flavor. They also feed primarily on plant-based foods, so they’re perfect for adding to an Aquaponics system.
Because they are so often grown on commercial farms, there are places where you are not allowed to own and breed tilapia. For example, in California, you can only own tilapia in the six southernmost counties. Make sure to check with your local fish and wildlife agency before buying tilapia–it may help you avoid heavy fines.
While goldfish are not edible, they make a great addition to your Aquaponics system. If you feed them right, they will produce a lot of waste material–perfect for feeding the plants you are growing. However, the high waste production means you have to keep a closer eye on the pH of the fish tank. In addition, you will need to ensure there is plant-cover in the tank if you want them to breed. Apparently, they are a shy fish.
The downside of goldfish is what to do with them after they’re grown. You can’t sell or eat them.
Few fish taste as good as a freshly caught trout. Trout have a delicious flavor that makes them the ideal fish to breed and raise. Trout also contain a lot of bones so filleting is paramount.
Trout tend to grow very quickly and have an excellent conversion rate.
Bass, Perch, Crappies
These fish are all carnivorous fish, which means that you will need to feed them bugs, shrimp, and smaller fish. This makes feeding them a whole lot more expensive than the other fish on the list.
A word of caution: Some perch and crappies cannot be imported into the US or Canada. Be sure to check with your local Fish & Game Authority before purchasing them.
This Japanese fish is ideal for those who want to make their Aquaponics tank look colorful and beautiful! They are almost perfect for an Aquaponics system, as they have a long life span, eat primarily plant matter, and are very resistant to the parasites that commonly affect fish.
Koi are easily obtained and produce a lot of waste matter, which is perfect for the feeding of your plants.
While pretty to look at, Koi are not a fish you want to eat. Pretty much, show only.
Anyone living south of the Mason Dixon Line will tell you, a catfish is one of the biggest growing, best tasting fish you’ll ever eat.
This was only a short list. There are limitless fish to grow for food or show. Do some research.
