When the individual reaches about 300 grams, the tilapia enter the fastest growing period, the daily feeding amount should be maintained at 1%~2% of fish weight, and the content of protein in feed is above 35%.
Do I need to add nutrients to aquaponics?
Additional nutrients such as Potassium (k) and Phosphorous (P) should be added to Aquaponics systems because they are not produced by the fishes in the tank. Plants as we know require Macronutrients such as Nitrogen, Phosphorus, and Potassium (NPK) as well as other micronutrients.
What type of fish is best for aquaponics?
Tilapia is the best fish to rest in aquaponics because they can adapt to their environment and withstand less than ideal water conditions. They are resistant to many pathogens, parasites, and handling stress. Tilapia is a hardy fish and has a diverse diet.

Grow your fish to harvestable size. Under proper growth conditions, tilapia fingerlings will reach harvestable size in 8 months. In addition to raising your fish for food, you may want to set aside some of your adult fish as breeders to produce fry and fingerlings to “reseed” your fish crop for another harvest.
How do you make tilapia feeds?
Some aquatic plants like water lettuce, water hyacinth or alligator are also good feed for Tilapia. Making feed by them, farmers just need to directly cut them into pieces or mix them into compound feed after cutting. Microcystis and Cyanophyceae are easy to digest to both Tilapia fingerlings and adult Tilapia.
Why are my aquaponics fish dying?

What nutrients are lacking in aquaponics?
1) Potassium in aquaponics: commonly deficient and tricky to manage. When it comes to interesting (and frustrating) nutrients in aquaponic systems, potassium takes the cake. Potassium is the most commonly deficient nutrient by far (9 out of 10 are a potassium deficiency).
Do I need to change water in aquaponics?
In a balanced system, essentially never. You will need to add water to replace water lost to evaporation or transpiration (water lost by the plants as they grow) but the system is pretty much self-cleaning.
Can you breed tilapia in aquaponics?
Even if the survival rates are very low, you’ll still get a tank full of tilapia fry within a very short period of time. If you’re planning to breed tilapia for your aquaponics system, this extremely fast breeding rate can be both a blessing and a curse.
Why is tilapia used in aquaponics?
Tilapia belongs to the Cichlid family of fish and is a popular food source because of its mild taste. They are often preferred in aquaponics because of these reasons: Tilapia is resistant to diseases and parasites. They can handle a wide range of water quality and temperature challenges.
