Traditional gardening and hydroponics respectively has its limitation, but the combination will benefit both. That is Aquaponics. Fish and plants will be grew in one integrated system, which the fish waste provides an organic food source for the plants and the plants naturally filter the water for the fish. The third participants are microbes. The bacteria convert ammonia from the fish waste first into nitrites, and then into nitrates. Nitrates are the form of nitrogen that plants can uptake and use to grow. Solid fish waste is turned into vermicomposts that also acts as food for the plants.

Aquaponics has many advantages, do you know? The author lists some for you.

●Use 1/6th of the water to grow 8 times more food per acre compared to traditional agriculture
●All natural fertilizer source from fish waste
●The whole process is free of pesticides and herbicides
●Integrated system is sustainable and earth-friendly
●Gardening chores are cut down dramatically
●Aquaponics systems can be put anywhere.
●Aquaponics systems are scaleable. They can fist most sizes and budgets.
 

NO.1 How to start?
Research thoroughly and contact people who are doing it. Make a plan on what to grow, production timeline and how to sell. Starting a small one with enough cash flow is a good choice.
 

No.2 Which plants and fish to choose
The selected fish and plants should have similar requirements about temperature and PH. For the plants, leafy crops such as lettuce, greens and herbs are better. The selection of fish species for an aquaponics system needs to be based greatly on the type of the climate present. Another important factor is the home you want to place the fish in. The number of fish is also very significant. Growth rate of a fish is also another important that needs to be considered. With all these factors in mind, there are top 5 best aquaponics fish species for you to choose from.
1. Tilapia
Tilapia is the easiest to breed for they can withstand even very poor water conditions and grow fast. The taste of Tilapia is also very good.
2. Trout
Trout is second best in the list because of its fast growth rate. Besides, it can provide enough food for plants, other fish and insects.
3. Goldfish
Although it is not a good choice for eating, it produces more wastes on the way they are fed. Therefore, it is very important for an aquaponics system.
4. Carp
This fish species appears in this position of the list because they can adapt easily in any environment. It is also good for food.
5. Catfish
Catfish tastes good and grows fast as well. Plants in the system with this fish always have plenty of food because the fish species convert food to waste at a solid rate.
 

No.3 What facility to prepare
There are mainly three things: tank, grow bed and pumps. The pump can either collect the water that drains from the grow beds and put it back or it can be placed in the bottom of the tank and used to spread the water over the surface of the grow bed. For satisfying the need, fish pond aerator is very suitable.
