The location of the land

Find land closer to your target market for easy transportation of your product after harvest. Also the location of the land should be mobile to facilitate the movement of food or equipment.

The topography of the land

The topography of the proposed site should be generally flat with a gentle slope, which is very suitable for establishing a commercial tilapia fish farm with minimum financial investment.

Soil factors (it depends)

Some farmers prefer the concrete floor, some prefer to leave the pond terrestrial. Just be aware that the lower part of the earth must be clayey in other retention waters. But if the site is a sandy loam soil; still fine.

Hydrology of the territory

We all know that fish cannot live without water. So you should know that you should always provide a constant supply of water to your fish. Even if you change the water, you should still refill immediately.

Make a suitable water source, to fill your pond or if possible be aware that boreholes will also be constructed which should provide on-farm relief services especially during the dry season to keep your tilapia fish farm running for a while. all season of the years.

Plant cover or shade

You may want to consider planting a tree to provide shade for your tilapia fish. To activate a normal temperature for fish.

Prepare and manage your tilapia ponds

These are the necessary preparations to participate in your farm before bringing your fish.


Lime is used to purify the water or the substance. For your fish pond, you will use it to neutralize the acidic nature of the soil, promote the growth of phytoplankton, eliminate harmful bacteria, deposit soil particles suspended in the water. Also promote the formation of mineral elements necessary for the most favorable growth and progress of the tilapia fish.

Lime is usually diffused to the bottom of the pond at a rate of 450 kg to 500 kg per hectare and will be allowed to stay there for about two weeks. As soon as the pond construction is fully completed and the water control structures are in place, the ponds will then be limed using either agricultural lime or quicklime.


The application of fertilizer which can be organic fertilizer made from (cow dung, poultry waste, pig waste, etc.) or inorganic fertilizer (NPK, urea, superphosphate, etc.) can be used to fertilize the ponds.

These fertilizers are applied in ponds a week before storage and also help accelerate the growth of phytoplankton and zooplankton which are best known to be the natural food of farmed fish.

Stocking up on Tilapia fish

After preparing your fish pond, it is time to introduce your tilapia fish into your pond. The fish will be stocked at a rate of 10 to 50 fry per square meter for your fish depending on the production system. It is best to introduce tilapia fish into ponds in the early morning or late evening especially when the sunlight intensity is very low.

This is to avoid unnecessary stress which could lead to high fish mortality a few days after stocking.

Build a farm building and infrastructure

It is recommended that you build a residential dwelling on the site of your tilapia farm for the occupation of the workers, who will be available to feed and monitor the fish.

But if you think that this will not be necessary, it will not cost you anything either.

Feeding your Tilapia fish

The feed should be supplemented with specially formulated and compounded fish food to accelerate the growth of the fish to their upper limit capacity. Fish should be fed twice a day with their food at 5% of their body weight.

You can produce your own fish food if you wish, all you need is a feed mill unit including a hammer mill, mixer, dryer. Also a pelletizer capable of producing 0.5-5tons of feed per hour will be installed to produce the necessary fish feed for the farm. You can also sell your feed to other fish farmers who might be interested in buying it. This can also add an increase in dependency to your profit.
