So you must select proper or suitable eel fish species for your fish farming business commercially. Here some of the suitable species are given below form which you can take one for your respective farm.

Japanese eel (Anguilla japonica) -It is most common in the fresh and brackish waters of Japan, Korea, China, and Taiwan. This eel is particularly suited to pond cultivation in these countries as they are naturally acclimatized to higher water temperatures.

Eel Fish Farming:

First of all, secure the water body for eel fish farming. You can grow eels both in the pond or tank.

Firstly, fill the tank or pond with clean fresh water. Basically, you have to procure the glass eels. You can capture glass eels from the sea or you can procure from the hatcheries also. Generally, you can use scoop nets and traps for catching glass eels.

Secondly, after procuring the glass eels, keep them in the smaller tanks. Here, you have to check the eels whether they are disease-free or not. The eels are also weaned to artificial diets with cod roe and, later on, dry starter feed.

Finally, when the eels reach approximately 5 g, transfer them to a juvenile production unit with larger tanks (6-8 m²) and stocking densities (50-75 kg/m²). At this point, the eels can digest dry feed pellets (1 mm).

Feed Supply

You can raise the eels in your farm commercially with locally available and natural feed. It is not only economical but also environment-friendly. For instance, feeding the golden snails to the eels will be a good and natural method of managing the pest as well. You can also use formulated feeds in the form of a moist paste for glass eels and steam-pressed or extruded pellets for the later stages. Though the types of eels feed are tend to be similar to other fish. The feed can be given at the eel, among others:

  • Earthworms
  • Protein pellets more than forty percent, either sinking or floating.
  • Shrimp and small crabs live.

Providing eels with the right food is important to their health and growth. Being meat eaters, protein is an essential requirement. Commercial foods are widely available. Commercial foods contain a protein paste for young eels and pellets for older eels. These foods consist of high-quality fish proteins, oils, and nutrients to produce optimal growth.

Monitoring and Care

Proper monitoring and care are essential for successful eel fish farming. When growing eels on in ponds or tanks, regular monitoring or grading is the must for reducing pattern and competition for food. After every 6 weeks, you must grade the eels and record it which will help you to compare with the previous record. Additionally, you have to separate them into different sizes in different categories. If you keep all different sizes together, the larger eels will eat the smaller eels, and it is one of the natures of eel.

There are many designs of fish grading equipment commercially available, yet they all work using the same principle. They consist of an entrance that the fish swim into, and then different sized gaps allow the smaller fish to return to the ponds or tanks while retaining the larger fish that can be moved to other tanks or to be prepared for harvesting.


Harvesting is a very important step for any kind of farming activity. Because if you do everything properly but you have no idea about proper harvesting then the output will not be desired and consequently your eel fish farming will be hampered..You must harvest the eels by grading the sizes to make sure each eel is large enough to reach market value. It is important to keep stress to a minimum while grading, so as not to affect the health of the eel. Put the large eels that are ready for harvesting into tanks with clean water to flush out any possible impurities in their systems that could affect the taste. Additionally, stop their food 1-2 days before harvest.


The final step of any commercial activity is marketing. Proper marketing depends on several strategies, such as market demand, market value, aggregate supply, etc. So to execute a successful eel fish farming business you need to consider all of these important facts. Additionally, you have to manage the eels according to their end-use. Chill the eels that are to be freshly consumed. Put the fishes into bags that are filled with oxygen. There should also be enough water in the bag to keep their skin moist. They are then ready for transportation to the market. Eels that are to be smoked are usually transported alive to the processors.

Manage Pond or Tank for Next

Proper post-harvest management is important for eel farming business. After each harvest, you must clean the tanks properly. Additionally, use the sun drying method for a few days before taking up fresh eel farming again, and thus you can run a successful eel fish farming business properly.
