How A Home Aquaponics System Can Feed Your Family…Forever

Aquaponics is a merging of hydroponics, which involves plant cultivation without soil, and aquaculture, which refers to fish farming. The two techniques are complementary, resulting in an incredibly effective food production method that is considered one of the most efficient methods available.

When considering aquaculture as a separate entity, the predominant issue usually involves eliminating fish waste from the system. This occurs when fish are fed, and subsequently excrete waste. The typical solution for this problem is through filtration systems, although this does not completely eradicate the issue of waste production. Rather, it simply removes the waste from the system.

When considering hydroponics, the main input is typically a nutrient solution, which must be periodically purged from the system like in aquaculture. As a result, there is a comparable level of waste in hydroponics systems.

Aquaponics plays a critical role in rescuing the situation.

Although it may seem like I am criticizing aquaculture and hydroponics, I am actually not. They are significantly more effective than the current method of producing food, which involves cultivating large areas of monoculture on land.

Aquaponics offers a solution that effortlessly overcomes the issues that arise from traditional farming and fish breeding practices, while simultaneously yielding fish and plants. There’s hardly any reason to oppose such a method!

Other Advantages to Aquaponics

Very space-efficient
No need to weed or water the garden ever again
Growing beds are typically elevated, meaning you can garden standing up
Plants grow quicker, are larger, and are chock-full of nutrition
You can pull fully-grown fish out of the system whenever you need them
Can be run indoors
No need for pesticides or fertilizer ever again

Small-Scale Aquaponics for Beginners

Aquaponics has been criticized for requiring a substantial amount of expertise and labor to establish. Nonetheless, this only pertains to the enormous systems capable of generating hundreds of pounds of fish and crops per month. If you want to start small, you don’t have to worry.

Starting with a smaller system may result in a minor decrease in efficiency, but it is inconsequential. It is important to commence somewhere, and beginning with a smaller system makes it simpler to comprehend the intricacies of the cultivation process.

How to Make An Indoor Aquaponics System Work

The cultivation of indoor plants has been acknowledged for its beneficial impact on individuals. Usually, people inhale the oxygen produced by plants during photosynthesis, which is necessary for the proper operation of their bodies. Therefore, it is not surprising that houseplants have gained widespread popularity in modern households. Moreover, it has been observed that certain types of crops can thrive indoors.

It’s logical to cultivate plants that offer additional advantages apart from tending to them. Ones that serve the dual purpose of producing fresh edibles and enhancing home decor. Indoor aquaponics offers a convenient way to achieve this, eliminating the inconvenience of fertilizing, potting soil, and watering.

The cultivation of plants and the raising of fish indoors is referred to as indoor aquaponics, with the two entities existing in a mutualistic partnership. The fish discharge a substantial amount of waste, which happens to contain the essential nutrients that plants crave.

The process of filtering water in a fish tank is essential in preventing the buildup of harmful waste that can cause toxicity to the fish. In the case of aquaponics, the waste from fish is utilized by plants and worms, therefore eliminating the need for removal especially in small-scale systems.

The fish tank water is cleansed by plants in order to provide a suitable habitat for the fish. This allows for water to be reused repeatedly in indoor aquaponics. Waste generated by the fish holds nutrient properties that are beneficial to the plants, thus keeping the water consistently clean.

Plants do not necessarily rely on soil for their growth; rather, they use it to extract nutrients and water. By providing plants with direct access to nutrients and water in a closed, well-lit environment, like a room, the need for soil can be eliminated. By doing this, the tedious tasks of soil preparation and dirty work can be avoided, enabling the production of indoor food crops and fresh fish that are devoid of any harmful substances.

The aquaponic system is commonly used in closed systems like greenhouses or, weather permitting, outside. However, it also works effectively indoors. One of the benefits of setting up an indoor aquaponics system is that you can regulate the climate to suit the demands of your system. When growing outside, the weather dictates what you can grow and when. On the other hand, with an indoor arrangement, you have control over the surrounding temperature and can get rid of typical garden pests. You won’t have to deal with pests like snails, gophers, weeds, slugs, or any other common pests that plague gardening systems.

Aquaponic systems allow for greater food production in a limited area while also providing the opportunity to rotate crops and create an aesthetically pleasing display in one’s home. Further, imagine being able to harvest organic produce from the comfort of your own living space.

What Types of Fish to Use in Small-Scale Aquaponics

Although the selection of fish type relies heavily on location and climate, there are several commonly regarded “good species” that are generally effective.

Trout – Trout grow fast and have a good food-to-meat ratio. This means that they convert the food you give them to protein very efficiently. You’ll need to keep the tank cool, which means you save money on water heating. Trout is a carnivorous fish, meaning you’ll need to feed them insects, smaller fish, or fish food that is meat-based.
Tilapia – There is a reason that tilapia is the go-to fish for aquaponics. They taste great, breed well, and grow extremely fast. They require warmer water than trout but are also very hardy (so if you make mistakes, you won’t ruin your system). They eat plant-based food, meaning they’ll do quite well in your system.
Carp – Carp is a less common choice for a system, but it can work well. They’re hardy and adaptable like tilapia and are oily fish, meaning eating them will fill up your omega-3 requirements more than other types of fish. They eat an omnivorous diet, so feeding them isn’t an issue.
Catfish – There are many types of catfish and most of them are good fits for an aquaponic system. They’re similar to trout in their growth rate and efficiency in converting food to protein. If you’re a fan of the flavor of catfish, they may be the choice for you over trout or tilapia.

If your priority is the efficiency of an aquaponics system rather than the ability to harvest fish for food, you may want to consider trying certain fish species that are incompatible with consumption but perform effectively in the system.

Koi – If you’re looking to build a beautiful aquaponic system, koi may be the species for you. They’re absolutely beautiful and a good fit for aquaponics. The downside is their cost, although they live quite long lives and don’t have many issues with diseases or pests. You can also breed and sell the offspring for a nice side income.
Goldfish – Goldfish aren’t great to eat, but work well in aquaponics because of their waste production. Remember, fish waste = plant nutrition, so having a high waste-to-size ratio will be great for your produce growing above the fish tank.

What Kinds of Produce Can You Grow?

It is advisable to cultivate uncomplicated plants that do not demand excessive maintenance or unique techniques, especially when beginning your aquaponics journey. Although an aquaponics setup can accommodate various types of plants, it is prudent to begin with simplicity.
