Backyard Aquaponics
A place to discuss aquaponics

Hi,
I have a total grow area of 240 square meters. I want to know what is the size of the fish tank and fish density. I used UVI standard but the number is really big. As suggested by UVI 60g/m2/day is the feeding rate. Since my grow area is 240m2 then I will need 240x60=14400g per day. Since fish feeding is 1% of fish mass then I will need 14400/.01= 1,440,000g=1,440kg of fish mass. If the density I use is 11kg/m3 then the tank size will 1440/11=130m3 which is 130,000 liters. Is this calculation correct?

The main thing is your biofiltration, which would be your type of media (gravel/hydroton/etc.) and the cubic meters (volume) of your media.

From there you can find out how many fish you can support and fish tank size for that many fish.

That is a large growing area.. I'm assuming that you will be basing your system design on UVI and it will all be DWC?

Yes earthbond it is based on UVI design and will be mostly DWC.

i think you might be mixing up some of your numbers and multiplying things that should not be combined. but good luck anyway.

1% feed rate would be more applicable to adult fish.. juveniles might be closer to 5%...
