Backyard Aquaponics
A place to discuss aquaponics

We have 100+ tilapia fry in total of four 75 gallon sized tank and IBC tank. We used to have more than 300 but most of them have grown, sold, or died.

I have been had at least one fry died in the tanks pretty much everyday. Is that normal?
I have been checking the water and ammonia and nitrite are all normal (either 0 ppm or closest to 0 ppm).
Are they dying because there are a lot of fry in the tank. Wasn't sure if that is normal or abnormal.
if you have any idea, please I really appreciate for any advise. Thanks a lot!

Is it normal for tilapia fry and fingerlings are dying because there are hundreds of others even though water quality is good? Some could die just because they are weak?
