Backyard Aquaponics
A place to discuss aquaponics

My first system is about 2 years old . The second one is about one year old (it is ornemental ). The third one is 6 months old.
I will add some pictures and comment on them.

The second system .

In the second system the water is syphoned from the upper tube to the lower and then to the lowest and finally to the fish tank .

The third one . 4 GBs . 1 fish tank ( re purposed refrigerator body ) . 7 grass carps , 14 gold fish .

Nice system. How many fishes are growing in this? What are they?

Hi Nanniode , there are 7 grass fish and 14 gold fish in the last one .

Harvest is a good thing

good work Katib, what are you growing in the third system?

Katib, I am trying to look at your duckweed grow bed closely. Can you explain its measurement? Do you get regular supply of feed for all your fishes from this setup? Do you feed your fish anything else?

Hi Slowboat . There are 7 grass fish and 14 gold fish in the last one . The vegetables are okra and basil and some ornamental trees .
Best .

Hi Nanniode ,
The duckweed GB is 2 meter by 1 meter , the depth is 15 centimeter . The duckweed I get from the first system , is fed to the Grass carp in the 3rd system . the tilapia and common carp in the first system are on regular pellets fish feed ( 2 handful every day with one day holiday every week ) .
Best

Hi again, so it is only for the grass carp. Tilapia and common carp - don't they eat duckweed?

That is right .

Hi Katib, duckweed can be given to tilapia also on a combination diet... check out this link, found it useful... http://www.mobot.org/jwcross/duckweed/fish.htm
