How to Start a Catfish Business with Plastic Tanks

Starting a catfish farm using plastic tanks is another way to achieve results. The tanks are durable easy to clean and install and the last several years.
Plastic tanks are ideal if you live in a rented apartment or house and cannot make any major changes or construction. Once the fish tanks are properly installed then you need to buy fast growing fingerlings and food.
Buying the plastic tanks
Fish pond plastic tanks are specially made for that purpose keeping fish. They are different from storage tanks made with little openings at the top.
Fish pond tanks have wide opening and are treated with non toxic paint to prevent harming the fish. The sizes of plastic ponds vary but in the Nigerian market there are three sizes.
Installing the pond
You can’t just place the tanks on the flour they need some sort of elevation. The elevation or base should be a concrete base to carry the heavy weight of the tank when filled with water and fish.
Building the concrete base
To get an accurate measurement of the base you need to measure the base of the tank. Once you have the measurement give 5 inches all around the base.
Align the block work along the perimeter of the measurement and build the base using granite, stones, cement and sand. When the base structure is finished allow it to dry for one week before putting the tank on it.
Piping work
Then you need to do the piping work which is the inlet and outlet. The tank has a provision for the outlet so the plumber only needs to attach a pipe and tap.
The inlet above the tank can be fitted with a dedicated tap connected to a water source. Rinse the tank thoroughly and retain water for a few days before introducing your fish.
If you are in a rented apartment make sure you channel the outlet via piping to a gutter. Please don’t channel the water to the sewage because the volume of water will make it over flow in no time.
Stocking your pond
Buy fingerlings from a reputable dealer and avoid overstocking your pond. You are at liberty to make a canopy cover or metal grill to secure your fish.  Fish feed comes in various sizes from 0.5mm to 10mm, and the feed are graded according to the size of the fish.
Once you have installed your plastic pond, stocked it with fish you are now a catfish farmer.

  1. Hi, how often do you advise me to change water? Is there such a thing as "too much of changing water"?

    1. There is nothing like too much water changing. however constantly changing the water would upset their growth. the ideal time to change is in the mornings or when the water is very dirty. sorry for the late response.
