Aquaponics Systems That Makes You Self Sustained For Food

Fish are the highlight of the aquaponics system. Not only it serves as a great food, the tank full of fishes carrying attractive colors will also serve as a great spot to lurk around for people who visits your home.

How to cultivate food for 7.3 billion world population is always a perplexing question. Total agricultural land is getting depleted and majority of population is depending on food cultivated by less than 5% of total population. More over in-order to maximise the production, farmers from under developed and developing countries are using pesticides and fertilizers beyond recommended limits. Some developed countries have already given green signal for Genetically Modified (GM) crops. This is leading to dangerous and non curable health problems like cancer.

Do we have a solution for this problem? Can’t we produce our own herbs and vegetables?  But in the absence of sufficient land space for cultivation, what can we do ?

Answer to all these questions is Aquaponics. It is a symbiotic system which is very common in nature. It uses both aquaculture, which involves growing and breeding of fish and hydroponics,(Here is 9 hydroponics systems to start indoor garden.) which is cultivating plants in water without soil.

Lets take a look at the aquaponics cycle:

As I explained before, this is a symbiotic relationship between fish, plants and micro organisms. Fish droppings contain ammonia, which is toxic for fish as well, if concentration exceeds beyond a limit. Plants cannot utilize ammonia as a fertilizer directly. But there are some micro organisms which can convert this ammonia to nitrites and then to nitrates. Nitrates serve as a good nutrients for plant growth and fish can live in this clean and aerated water.
