Aquaponics offers both commercial and home growers an organic way of cultivating food. By forgoing harmful pesticides, growth hormones and fertilizers, aquaponics relies solely on natural, sustainable fish waste to provide all of its essential nutrients, leaving no room for harm!
What Is Aquaponics?
Aquaponics is an innovative and sustainable farming system that combines aquaculture (fish farming) with hydroponics (soil-less plant cultivation). This method creates a mutually beneficial relationship where fish waste provides nutrients for plants, while the plants filter and purify the water for the fish.
Aquaponics operates on the principle of a closed-loop ecosystem, mimicking the natural processes found in ponds, lakes, and rivers. The system starts with a fish tank, where fish are raised. As they eat and excrete waste, ammonia is released into the water. This ammonia is toxic for the fish, but it serves as an excellent source of nutrients for plants.
The second component of the system is the grow bed, filled with a growing medium such as gravel or clay pellets. The water from the fish tank is pumped into the grow bed, allowing the plants to absorb the nutrients from the fish waste. The plant roots act as natural filters, removing the harmful substances from the water. The purified water then flows back into the fish tank, creating a continuous cycle.
Set Up An Aquaponics System
This system utilizes a fish tank or pond, growing beds, and a recirculating pump. The tank serves to ensure an ideal level of water is maintained in its environment; pumps circulate it while also keeping fish from collecting in one area of the tank. Additionally, its use eliminates stagnant areas, thus helping prevent diseases or parasites that might threaten fish health.
When beginning an aquaponics system, the first step should be identifying an ideal location. If your system will contain both vegetables and fish, make sure it is near both sources, with plenty of sunlight coming through, while having some type of protective covering or fence installed around it to ward off predators or insects from entering.
Aquaponics requires the use of a filtration system in order to keep water clean and free from bacteria that could harm fish or plants, as well as collecting any solids that have accumulated in the tank, and helping maintain optimal pH levels in the system.
Grow beds are another crucial element of an aquaponics system, providing a place to grow vegetables and herbs. There are multiple styles of grow beds suitable for aquaponics systems, including media-based beds and raft-style beds. They all share some basic components such as tanks, pumps and piping. Grow beds can also be constructed from different materials depending on individual gardeners’ preferences.
Media used in grow beds must be non-toxic to both fish and plants, with neutral pH levels. Furthermore, it must support beneficial bacteria that trap ammonia produced by metabolism of fish to serve as plant fertilizers, eliminating chemical fertilizers altogether from an aquaponics system.
Once the grow beds and tank have been established, it’s time to introduce fish. Aquaponics systems typically introduce fish when the nitrogen cycle has been completed and ammonia levels stabilized, and then feed on any produced nitrates and ammonia to further fuel nitrification processes. Their waste feeds into these processes too, providing essential nutrients to plants as well as acting as natural pesticides that won’t harm humans either.
The search volume is about 27,000 per month. The costs are not cheap and the competition is high. However, this niche should continue to maintain and even grow in the future.
The most obvious income solution is to be an affiliate for the various aquaponics suppliers in the market. However, you may need to get hand on in order to have credibility in this niche. Are you ready to put tanks in your backyard?
