Raising and harvesting fish and aquatic plants is known by fishkeepers as aquaculture. It’s used by many aquarists worldwide to create a healthy habitat for their fish.

If you’re interested in the idea of aquaponics on a smaller scale,  then you should check out this nifty water garden and fish tank combination to get your roots wet.

Steven Van Gorder, author of Small-Scale Aquaculture, states, “Backyard fish farming is as practical as gardening for producing food for the family. He goes on to say, “You can achieve a higher level of self-sufficiency and provide a healthier diet for your family.” If Gorder’s words sound good to you and you’re interested in tilapia because they’re cost-effective and easy to raise, then boy are you going to love this.

Follow these basic steps to learn how you can start your own tilapia farm.

Step 1: Set Up the Grow-Out Environment

Tilapia can easily adapt to any environment, whether it’s a pond, cage, tank, or raceway (more on all of these later). Some of these systems are low-maintenance, such as ponds and raceways. Tanks, however, require daily upkeep to ensure the water temperature and pH balance are ideal.

Tank water should be from a municipal source that’s safe and clean. It should be the same quality water that you would drink yourself. Bear in mind that tilapia soaks up water through their gills and skin via osmosis. And since tilapia are a food fish, whatever they absorb from the water will ultimately end up in your body.

If you find the water undrinkable, there are many things you can invest in to enhance the quality of the water. A few examples are filters, nitrate removers, and high-volume reverse osmosis systems.

Another tip to remember is not to run a hose from the water source into the tank. There have been cases when the water source had sudden changes in temperature or drops in pH levels. This can cause weakened immune systems in the tilapia, making them severely sick.

The next step is to check for any chemicals in the water, such as chlorine or chloramine. Use DeChlor to remove these chemicals and ensure a toxic-free grow-out environment.

You should also make sure that pH levels should range between 6.5 and 8.5. You can use a digital meter to get accurate readings.

Ponds, streams, and rivers, however, are easier to maintain. Tilapia will adapt and come to rely on the biological components in these natural water sources. They’ll also start to feed on the food naturally found in these waters.

Step 2: Buy Baby Tilapias

Generally, tilapia fish farmers start with tilapia fingerlings. They range in size from 0.75 to 2 inches. Make sure you’re getting your juvenile fish from a reputable dealer.

Another choice is to buy tilapia fry. These are tiny-sized fish that are less than 0.75 inches long. The downside with fry is that they need more attention and care. You can buy both here.

Step 3: Help Baby Tilapias Acclimate

Whether you pick fingerlings or fry, you should start by acclimatizing them to their habitat. This provides a gentle transition between the water in the bag and that of their new home.

Here are a few tips for a safe and hassle-free acclimation. A pro-tip: Be patient with this process and don’t rush it.

  • Fill a large container with water from the tank or pond.
  • Place the sealed bag with the fingerlings on the surface of the container.
  • Let the water in the bag adjust to the temperature of the tank water (about 15 minutes).
  • Add half a cup of tank/pond water to the container every five minutes for 15 minutes.
  • The final step is to net out the fingerlings from the bag and add them to the pond or tank.
  • Don’t add water from the bag into the pond water.

Step 4: Feed the Fish

Once fingerlings are in their new home, wait for a few hours before feeding. This gives them time to get used to their new surroundings.

After a couple of days, start to feed them 2 or 3 times a day. Start with a fingerling starter to boost growth and development. Then, when they’re about 1 ounce, use a grower type of fish food. Finally, when they reach 2 ounces, you can use denser food.

Continue this feeding schedule until they reach a size suitable enough for harvesting. That should roughly take anywhere between 30 to 34 weeks.

Step 5: Harvest Time

After about 8 months, the grow-out phase is complete. Your tilapia will have grown to be nearly 20 ounces and an average of 8 to 14 inches long.

Now would be the perfect time to set aside several adult tilapia for breeding. This is an important part of a self-sustaining tilapia farm. It allows adult fish to produce fry and fingerlings to begin a new round of fish harvesting.

If you’re planning on selling your fish to local markets or stores, you should have a marketing and sales plan in action. You may even have a couple of buyers already lined up.

If you’re planning on keeping them for yourself, there are many delicious tilapia recipes to choose from. They’re easy to make and highly nutritious.

Why Tilapia?

Tilapia are easy to raise, mainly because they can handle a wide variety of water conditions. They’re also highly resistant to parasites, as well as a number of diseases.

If raised under the right conditions, tilapia grow fairly quickly. These conditions include 84-degree water temperatures. But anything that ranges between 64 and 90 degrees would also be considered ideal. However, if the water temperature drops below 50 degrees, it can be fatal for the fish.

Maintaining a tilapia farm is relatively straightforward since they require little effort to raise. The most common types used in backyard fish farming are the java, blue, and Nile tilapia.

Tilapia is also easy to prepare in terms of cooking. This is one of the reasons why they’re highly popular. Plus, they’re high in essential nutrients, such as omega-3 fatty acids and proteins.


Tilapia farming is a profitable business to embark on. Tilapia fish are a tenacious species with a rapid growth rate. They’re also easy to maintain and raise. They’re the perfect fish for beginner fishkeepers.

Fresh tilapia is always in high demand by seafood outlets and restaurants. You can also let your neighbors know about your tilapia farm. Or you can even put a sign in the front yard to advertise that you’re growing and selling fresh tilapias.

Some backyard tilapia farmers limit their fish production to what their families can consume. This helps promote a more self-reliant and well-balanced lifestyle.

Aesthetic Appeal

One of the best features of backyard tilapia farming is that you can be as creative as you want. There are many design choices and unique landscaping to help you make the most out of your fish farm.

Some tilapia farmers set up ponds that can stand on their own or be incorporated into the landscaping. They can also set them up as full tilapia gardens. These gardens are capable of producing thousands of pounds of tilapia each year.


Using the correct aquaculture methods, you can have a neat looking tilapia pond that’s super-functional too! Check out these four types of aquaculture for your tilapia farm. Then, consider the space, money, and effort you’re willing to invest.

Cage Culture

If you have access to a pond, setting up a cage culture to grow fish is simple and pretty straightforward. It’s also quite affordable compared with other types of aquaculture systems.

For cage culture, all you need is plastic pipes to make the cage frame. You’ll also need rigid netting to connect the pipes together. After putting the pipes and netting together, tether and secure the cage into the pond.

There are many similarities between a flow-through system and a cage culture. The only difference is that flow-throughs divert steady sources of freshwater into what experts call ‘raceways.’

These water sources can be a spring, a stream, or a river. Raceways are basically artificial channels where the fish are housed.

 It’s worth mentioning that flow-through systems are liable to codes concerning the diversion of natural water sources. So talk to local fish and water authorities first.

Greenhouse Aquaponics

Greenhouse aquaponics is when fish are raised side-by-side with different kinds of vegetables. How it works is that farmers use water from tilapia ponds to water the plants.

The great thing about this water is that it’s full of nutrients. When added to the soil, these nutrients boost the crop’s growth, which benefits them greatly.

As for the tilapia, it’s a great way to enhance the quality of the water by purifying it. Tilapia depend on the water to feed, breathe, and grow. So this is an important part of maintaining a balanced water environment.


Setting up a self-sustaining tilapia farm is becoming increasingly popular among professional and amateur aquarists. Tilapia fish are easy to raise. They also have a fast growth rate, which ensures a steady supply of harvest.

You can choose to use your tilapia to provide healthy meals for your family. There’s also the option of marketing your fish farm and selling them to local restaurants and fish markets. Either way, you’re sure to enjoy raising, maintaining and eating this hardy species.
