Water is essential for a fish. Once the fish is out of the water, it cannot survive too long. Fish can never be grown without water, so you need a reliable water supply.

Natural water that is free of chemicals and waste products such as feed is considered more appropriate for a fish farming operation. You can create a fodder with a suspended tank as a reservoir.

In addition, you must consider how the water system can be connected to the ponds, i.e. the water inlet and outlet installation. It must be constructed in such a way that waste water can be drained off and fresh water can be supplied daily.

If wastewater is not drained and replaced with fresh water on a permanent basis, this can lead to fish mortality, which will cause you to lose your investment.

Storage
The fish are stocked in different sizes; fry, post-fry or juvenile.
You can decide which size to farm but the most common fish that becomes the size of the table within three months is the juvenile fish.
You can start hatching or you can buy them from a hatchery and put them in your pond. Just make sure you choose healthy species so that you don’t start to suffer the death of the fish. And Feeding
The next step is to feed the fish once or twice a day. What you put in is what you get in terms of food. For example, a well-fed fish can be good for harvest in about 2-3 months.
When you feed the fish, the size of the fish determines the type of food. For example, catfish fry in hatcheries are fed finely ground meal or meal-type feeds containing 45 to 50 percent protein. While larger fry are fed small floating pellets (1/8 inch diameter) containing 35 percent protein.
As they grow, the ration increases. In addition, antibiotics can be mixed in their feed combination.

A fish can be fed in two ways:
Diffusion feeding: this involves going around ponds to spread floating feed for the fish. It is mainly done for fry to fish in the post-juvenile stage.

Spot feeding: this involves feeding the fish in one place. This can be done after 2 to 3 weeks of storage of juvenile fish. This way you can monitor how the fish eat.

However, you have to make sure that the fish are not over-fed as this can lead to a loss in the business.
Harvesting
As long as you feed the fish enough, they become marketable after about 2 to 3 months. Farmed fish of marketable size can be harvested in two ways: from drained water or from a filled pond.
In addition, you can do a partial harvest by catching the larger fish to increase the living space and make the pond more habitable for the smaller fish.

For a general harvest, it is advisable to start your harvest early in the morning when the weather is cool. Start draining the water by opening the drain valve if it is a constructed pond or by using water pumps for earthen ponds. Then use a basket to take the fish out into another prepared pond. You can also use harvesting nets.
Marketing
The market opportunity for the fish sector in the DRC is enormous. For example, the Congolese consume about 500 thousand tons of fish per year. In addition, the demand for fish far exceeds current production.

Therefore, selling your fish will never be a problem as long as awareness is created. It is advisable to start your marketing before the fish is harvested. To create an awareness price, the online space must be well used. Then approach hotels, bars, cafes, public event organizers and homes.

Similarly, you can have them smoked, packaged and distributed in supermarkets, stores and other small stores where customers are sure to frequent.
