To start fish farming, first assess the market and returns of fish farming, then undergo training in fish farming and set up a small-scale fish farm. Expand the farm once you gain experience.
To assess the fish market, identify if there is a market gap by analyzing the demand and supply of fish. Once you realize that the demand exceeds the supply, evaluate the resources at your disposal, which include time and capital. Additionally, calculate other costs that you are likely to incur, including the operating and legal costs such as licenses. Then, compare all the costs against the projected returns to determine the profitability of the project.
The profitability of fish farming may not guarantee you success in the absence of proper knowledge and skills in fish management. The knowledge and skills that are necessary in fish farming include fish disease control, water quality management and feeding. As a fish farmer, you should also know how to market your fish and process them before selling. To acquire the necessary knowledge and skills, consider working on an already established fish farm even though this may not earn you enough income.
Once you acquire enough training, proceed and start a small fish farm, preferably as a part-time project. You can do this by building a couple of fish tanks. If the project proves to be profitable, add more capital, and increase the fish production.
