Pisciculture, fish farming or fish rearing is a great business to begin as an entrepreneur. This is so because almost everyone eats fish, a popular source of protein in our world today.
Investing in fish business is a splendid idea for those who have the knowledge of aquaculture. This is so because a little capital is required to commence this business. Importantly, knowledge on the business side of fish farming is crucial.
Fish business can be very profitable if you get it right. You can easily sell them to the people and restaurants in your neighborhood. You can also minimize your operational spendings by gathering the waste from your environment and the kitchen, utilizing them as feeds for your fish.
If you have little or no idea about fish farming, just relax and carefully read this article, follow the instructions and you will see how interesting fish farming can be.
Firstly, let’s consider some reasons why you should embark on fish farming:
Below are the procedures one will need to follow as a new fish farmer.
Knowledge is power. Before you go into any business, it is important you have some understanding about the business. In the case of fish farming, you need to understand the physiology and anatomy of the specific fish you intend to rear.
You can start by visiting some of the fish farms around your area. You may also want to utilize the social media platforms on the internet to connect with those in the fish business. In this regard, google, bing and other search engines will be your best friend in terms of learning, direction and knowledge. YouTube is also an ideal platform for visual knowledge.
It is also a good idea to register with a fish training class around your area. You can also sign-up for some online webinar courses in fishery. Joining fishery groups on whatsApp and facebook is also encouraged. Additionally, you may decide to work for free in one of the fishery sites around you.
Adherence to some or all of the above points is vital because knowledge is the key to any business.
Mapping out your business plan is important because it shows that you are indeed ready for business.
During business mapping, you plan the type of fish and the number of produce you intend to make depending on the market demand. To achieve this, becoming familiar with those in your neighborhood can prove useful since they are likely to become your first customers. Also, you will need to calculate your capital and the amount of profit you expect from sales after all expenses had been made. If required by your local law, you may wish to get your fish business license.
It is advisable you begin small because this is probably your first time in the business. You can always expand as the business grows.
Finally, consider all other possible factors before you make a conclusion on fish farming, whether it will be a good business for you or not.
You will need to create the appropriate space needed for your fish farm. Since it is recommended to begin small, you may dig a fish pond somewhere in your backyard, or better still, get a container, tank, tub or even barrels where you can raise your fish. Connect a water system to your fish container, tank or the dug hole.
With due diligence, make sure the water source is clean and reliable. Your water source could be from a bore hole, or well or from the public water supply.
Based on the knowledge you have acquired on the specie of fish you wish to rear, buy the juvenile fish from a wholesaler and don’t forget to ask for directions and procedures towards its management.
Make proper enquires and buy the best feeds for your young fishes. In addition, seek for instructions on when to feed them with the appropriate diet. It is a good idea you read about the dietary control concerning the specific fish you rear.
Monitor the temperature and pH of your fish pond. Always replace the water in your fish pond every time you need to. Once again, constantly monitor the pH of your water, making sure it is neither too acidic nor alkaline.
As your fish grows, you may need to separate the bigger fish from the smaller ones, so as to prevent them from preying upon the smaller fishes.
Finally, always avoid overpopulation of fishes in your fish tank. Also, make sure the available resource is enough for all the fishes.
Note: Whenever things don’t go right, always be quick to ask for assistance from a seasoned fish farmer.
I will further encourage you to read more articles on aquaculture and pisciculture to further increase your chances of success in this business.
