Aquaponics refers to any system that combines conventional aquaculture (such as raising fish in water) with hydroponics (cultivating plants in water) in a symbiotic environment. In normal aquaculture, excretions from the animals being raised can accumulate in the water, increasing toxicity. In an aquaponic system, water from an aquaculture system is fed to a hydroponic system where the by-products are broken down by Nitrifying bacteria initially into nitrites and subsequently into nitrates, which are utilized by the plants as nutrients, and the water is then recirculated back to the aquaculture system.
My Aquaponic System
In my aquaponic system, there is a 500 litres capacity pastic water tank. Tilapia and Pangas fish are growing in this tank. Fish meal are supplied to this tank which are utilized by the fish. Fish excreta are mixed with tank water which are pumped 3 times daily for 30 minutes each time to plant bed of brick chips on plastic drum cut longitudinally. Plant take their nutrition from the supplied water. Waeter collected back to water tank via 4 inch PVC collecting pipe. Air bubbles are supplied to fish tank via aqurium air pump.
My aquaponic vegetable
About 44 types vegetable has been grown in this system, among them Broccoli(sobuj kopi), Couliflower (fulkopi), cabbage (badha kopi), turnip (ool kopi), raddish (mula), carrot (gajor), capsicum (red, yellow, green, orange colour), gourd (lau-long, oval), cucumber (sosha), tomato, potato, bean (seem), bitter gourd (korola), brinjal (begun), onion (piaj), garlic (roshun), cumin (dhonia), red amaramth (lal shak), kolmi shak, ginger (ada), lettuce, spinach (palong shak), vine spinach (pui shak), arum (kocu), mint (pudina), strawberry, sent moshla, etc has been noted here.

Dr. Salam's Rooftop aquaponic system.
History of My aquaponic System
I am very much interested to gardening from my childhood. After construction of bulding in Mymensingh I got about 2400 sft rooftop space. My wife Feroza Akhter Swapna is also interested in gardening. We started tob gardening in 2013 on rooftop. We collected plant from Bangladesh Agreculture Univirsity, local nursuries and from different districts via parcel services for tob gardening. Collecting soil and fertilizer were our main problems. On 7 August 2016, my wife showed me a documentary video clip in YouTube where plants were growing without soil. We were very much interested to this system. We found that this is in our city Mymensingh. This is Mr. M A Salam of Mymensingh. I searched and found M A Salam in facebook. I wrote in his facebook status and wished to communicate and visit his system. He invited me. I visited his system on 12 August 2016. I constructed the system with the help of my sanitary system maker and with advice of Dr. Salam. My system started on 1 september 2016. I is working fine. We are now happy with this system.
