In fact they only have five basic needs: clean water, oxygen, food, light and room to swim. Give your tilapia these things and they will stay healthy and grow fast. The art of tilapia farming is to understand each of these needs and then find a way to provide them in sufficient quantities.
What does a tilapia fish eat?
algae
Tilapia in the wild feed on algae, but on farms they are reared on corn or soybean meal. However, when no other feed is provided, they will eat “poop.” There have been instances where fish farms in Asia were found to be feeding poultry, sheep or hog manure to tilapia.
How do tilapia fish survive?
The fish is tolerant to a variety of living conditions. It can survive in a pond with a high stocking density, and relies on cheap feeds, such as cereals and vegetable diets. In addition, it grows fast and takes a few months to be ready for harvest.
Do tilapia need lots of oxygen?
Tilapia are able to survive levels of dissolved oxygen (DO) below 2.3 mg/L as long as temperature and pH remain favorable. In fertilized ponds, a bloom of algae can reduce oxygen levels to as low as 0.3 mg/L with no fish mortality in tilapia.
How much water does a tilapia need?
How Many Tilapia per Gallon of Water? A fully grown tilapia will weigh 1 pound, although they can grow larger. The rule of thumb is that one pound of tilapia will need 3 gallons of water. So this means that in every 3 to 5 gallons of water, only raise one tilapia.

How much do tilapia eat per day?
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%. Fish should be fed feed five times daily.
Why are my tilapia dying?
Nitrate is relatively non-toxic to fish, but an accumulation of ammonia and nitrite can cause mortality. Tilapia begin to die at ammonia concentrations around 2 mg/litre (expressed as NH3-N) and nitrite levels of 5 mg/litre (as NO2-N).
How do tilapia protect themselves?
When they sense danger they fill their stomachs with water (or air if they are out of water). This exposes sharp spines that cover their bodies. This makes them less inviting for predators to catch. Their skin and some internal organs contain tetrodotoxins, which are highly toxic substances.
Does tilapia need light?
First is tilapia, as this is probably the most popular aquaponics fish that practitioners use. It requires at least 18 hours of light per day.
Which Aquaponics Fish Need the Most Light?
| Fish Type | Light Requirement (in Hours) |
|---|---|
| Tilapia | 18 Hours |
| Perch | 16 Hours |
| Koi | 12 to 13 Hours |
| Goldfish | 12 to 13 Hours |
Can tilapia live without air pump?
A short answer is something like this: Fish can survive about two days without an air pump in completely still water. However, with the right kind of filter producing lots of surface water movement, an air stone may not be required at all.

What helps the fish to live in water?

Food and oxygen are two of the most critical factors that dramatically contribute to the tilapia growth rate. Since tilapia is mainly herbivorous, feeding them an adequate amount of plant-based food will quickly help them reach their mature size.
