Pisciculture or 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. You will also require some little capital to start with, together with gaining some knowledge about the business side of fish farming.
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 (how the body functions) and anatomy (structure of the body) 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.
Google, Bing, Yahoo and every other search engine will be your best friend in terms of learning, direction and knowledge.
It’s also a good idea to register with a fish training class around your area or sign-up for some online webinar courses in fishery. Joining fishery groups on whats-App and Facebook is also encouraged.
Finally, you may decide to work for free in one of the fishery sites around you.
Note: Adherence to some or all of the above points is very important 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 your target market size.
Becoming familiar with those in your neighborhood will be useful because they are likely to be your first customers. You need to calculate your capital and the amount of profit you expect from sales after all expenses have 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's recommended to begin small, you may dig a fish pond somewhere in your backyard or better still, get a container or tank or tub or even barrels where you can raise your fish. Connect a water system to your fish container or tank or the dug hole.
Note: 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 whole-seller and don’t forget to ask for directions and procedures.
Buy the best feeds for your young fishes and also seek for instructions on when to feed them with the appropriate diet. It’s a great 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.
Constantly monitor the pH of your water, making sure it’s 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.
Always avoid overpopulation of fishes in your fish tank; and make sure that 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.

NOTABLE POINTS IN Agricultural Science
Below are some common types of erosion:
Water Erosion: It is caused by rainfall and flooding on the topsoil. As a result of water erosion, some layers of the topsoil are lost.
Sheet Erosion: When an entire surface of land becomes eroded at a uniform (equal) level, such is referred to as sheet erosion. It is shown below:
Wind Erosion: It results from the actions of wind on a bare land. Wind erosion is often seen in deserts. Overgrazing and lack of vegetation cover will also enhance wind erosion on topsoil.
Soil erosion is defined as a process through which the topsoil is removed or moved from one point to another by agents like wind, water, man and animals.
Soil erosion occurs naturally (wind and water) and may also be facilitated by living organisms.
Soil erosion is more likely to occur on a sloppy land and land with no vegetation cover. When this occurs, the nutrient rich layer of the topsoil is washed away; and this ultimately results in fewer plants growing on such eroded soil.
There are about 630 different kinds of carnivorous plants.
Carnivorous plants are plants that derive some or most of their nutrients by consuming small animals, especially insects.
Carnivorous plants are also referred to as insectivorous plants.
Examples of carnivorous plants include sundew and Venus flytrap.
