Make Money from Home Grown Catfish Farming
In order to make money from catfish farming you must first understand the type of fish you intent to farm. Aquaculture is the growing of fish in a controlled environment either for commercial gain or for private consumption.Catfish is a delicacy and can be bought fresh whole, fillets strips or smoked no mater how it is processed for sale catfish farming is very lucrative.
Domesticated catfish has the advantage of good nutrition, well processed feed pellets, protection from predators a controlled breading environment and time. Catfish is reared in several countries such as Africa, Asia, United states of American, Canada and parts of Europe.Catfish is in great demand and it is consumed as a good source of protein, low fat omega 6 fatty acid and vitamin D.There are many species of catfish ranging into the 100 but just a few will be highlighted bellow.
United States of America - Blue cats, Flat heads, Channel catfish
Asia - Walking catfish, Shark catfish
Africa - Pangasiidae
India, Turkey, Syria - clariids
East africa - Clarias geriepinus
other countries - Pangasius, Bocourti
Catfish are fresh water fish that are found in inlets, rivers and streams. They have an elongated body and do not have scales on their skin. Most catfish species have long dorsal fins and 4 barbels which some use to move about on land and they have the capacity to breath air from the atmosphere. Catfish such as Clariidae of the order of silurformes which comprises 14 genera and over 110 species are the air breathing catfish.The head consists of the Nasal barbels, eyes operculum (gills), Mental barbel (chin). The fins are predominantly dorsal. pelvic, adipose and anal fin
The scientific classification
Which cannot be farmed at home
Which fish cannot be rared at home
Catfish can be found in inland coastal waters, rivers and are abundant in every continent except Antarctic, they are bottom feeders and eat through a suction action. There size varies from 1 kg to 100 kg
Before you can grow catfish there are some things that you should put in place that would make the aqua cultural experience fun and easy, you would need to have some land space, electricity, good water source, good fish stock highly nutritious fish meal and other equipments.
Big aqua cultures use vast land spaces going into hectares of land they have the advantage of large numbers and discounts (wholesale prices) for the large quantity of feed while smaller farmers have to pay the retail price. The amount of food and pricing can make or break a fish farmer.
Large farmers spend tens of thousands of dollars on catfish feed but small home grow catfish farms can make profit on roughly a third investment their total investment. The home farmer only needs a little space to get a good harvest.a quarter plot of land can successfully grow 100 catfish or in the inter-em 28 feet sq.
Electricity is a serious problem for third world countries and can run into hundred of dollars which reduces profit. Electricity is needed to pump water in and some times out of the pond. An electric pump is a must have.
Good water source
Without good clean water your fish will not grow and might die so clear clean fresh water is most needed. You should randomly check the Ph level to maintain purity. Catfish are very rugged and can stand hard water for a little while.Some sources of water generally used are Bore hole, tap water, well rainwater, pond water river water and streams.
Buying good healthy fingerling or juveniles can help reduce the mortality of your fish stock. Take advantage of shooters, the fast growing fry ones among them for quicker growth.
Catfish can eat almost anything they are omnivorous in nature. For greater yield fish farmers should buy ready made feed. The feed comes in pellet form of various sizes ranging from 0.5mm to 10mm. You feed them once or twice daily. Over feeding can affect the pH level of the water and could kill them, any evenness food in the water should be removed.
A good feed content
The pellet sizes of catfish food varies according to the size of the fish it ranges from 0.5 mm, 2- 3 mm 4 - 5 mm, 6 -7 mm, 9 -10 mm. The grange is starter, grower, grower, grow out. The nutritional properties of the feed are 1 crude protein, moisture, crude lipids min, crude fiber max, calcium max, phosphorus min, vitamins.The feed also contain so ya beans,corn, shrimps and protein.

How to build a catfish pond
Well constructed pond
Although ponds differ in sizes and material used they must be chemical free waterproof and durable. Ponds can be made from materials such as tanks, cage, block, plastic.The main feature of the pond must be an inlet and outlet.
An aerator is a must have if you want quick growth. They can grow without one but it is better to use one.The growth rate for cat fish varies from 4 moths to several years. The weight of the fish determines the price you get. The heavier the fish the more money you would make.
The type of culture system determine the medium the farmer is willing to use.
Flow through system
The flow through system is a water inlet that flows through the pond thereby reducing organic waste and naturally increasing aeration.
The closed system
This is a stagnant body of water that is introduced naturally like a lake without an inflow or outflow of water.
The semi open system
Has no specific inlet or outlet
The recycle system
The reuse of a body of water by a water pump that has an intricate inlet and outlet.
Type of ponds
The catfish is farmed in artificial environments called ponds. Ponds come in different materials such as block, concrete, wood, plastic,soil and polypropylene.
ponds maybe above ground level block, concrete or within the soil like dug out ponds, earthen ponds.
The dug out pond
Dug out or earthen pond use the soils natural topography of water ways like swamps, rivers. To get a dug out pond you need to excavate the soil to make a pond that can retain water. The ground could be a mixture of clay, sandy or swampy...
Constructing a dug out pond
A dug out pond is a hole in the ground that can retain water. The soil composition requirements should be clay, literate or sandy.Erect pegs 3 regions called inner slop, crest, outer slop. Dig out from the center and a sand is compacted to make it watertight, this is achieved from the liberal use of clay. The clay is rammed to fill the dug out hole which reinforces the sandy soil.
Dugout pond ranges between 1.6 meters to 2.5 meters. The earth is piled up on the crest where excess sand is leveled to form an outlet layer. Then a sloppy embankment is built as the walls of the pond, which is twice the length to the height.The top width of the wall can be 1 meter.
The width of the wall and height depend entirely on the farmer. Cat fish need at least 3 feet and at most 7 feet. of water. While making a dug out pond test the strength and pond walls. Identify the deepest point estimate the volume needed to fill in.You can re introduce the excavated soil into your pond.
Another way to build a dug out pond
Choose a suitable site and get the correct ;license or permit before you start. Cordon off the selected section using a rope cord and pegs to demarcate 30 x 30 ft perimeter. In order to evacuate use direct labor or hire an excavator to dig and sculpture the land into a 5 ft deep dug out hole. Terminate edge of hole in a stairwell slop of 15 cm over the desired water level, some fertilize the bottom of the pond but this method is outdated. An underlay, pool liners can be applied to cover the pond. An aerator, filtration system and skimmer can also be introduced though optional. The pond bottom conditions may have hydrated lime 114 kg/ha ground lime 200 kg/ha agricultural lime 140 kg/ha.
Block ponds are highly recommended they are easy to build and use..Block ponds are built above ground as a square water proof chamber, should have an inlet and outlet and should not be higher than 5.5 feet
Building a block pond
Demarcate, built up with blocks using cement, sand for walls and some water proof cement. make it water resistant Introduce pump and a cage covering. The inlet allows clean water enter the pond could be from a water reservoir and an outlet when you want to remove the dirty water. On the outlet put a net to prevent the small catfish fro escaping.
How to build a block pond
Pick an appropriate site within your compound close to a water source. For it to accommodate 100 fish a land space of 30 x 15 ft ground is prepared and cleared of all foliage and rocks. Then demarcate outline of pond, ram pegs at the 4 corners and tie a turgid rope to its ends this shows a visual layout of the pond. The ground is then dug 5 inch and the block is placed in the cemented floor.
They form a rectangular frame which is built up, the bottom is then back filled with a mixture of granite stones, sharp sand, water proof cement and regular cement to make it water tight.
Ready made tanks
Ready made fish tanks come in different shapes and sizes. To choose the appropriate one it should have an inlet and outlet and a minimum capacity of 500 gallons. tanks that has a capacity of 300 gallons can contain 500/1000 catfish.
Start a small catfish farm
Stages of growth
Eggs > fry > juvenile > grower (adult)
Fry and juvenile require high protein based feeds for rapid growth. Grow out needs protein fats minerals, limpid The protein could contain some amino acid while limpid have fats which can be found in ground nuts. They also require vitamins c,b-12 and d. Good ready made concentrates have most of these.
Domestic catfish are bred through artificial insemination/inducement, water temperature, dept, clean water and aeration. After fertilization they are kept in a holding cell or hatchery were over 1000 fry emerge. The new fry feed on zoo plankton and special powdery feed.
In some species it takes 2 weeks to become fry who in turn takes 3 weeks to become juvenile. Catfish are very resilient to diseases but farmers who observe strange behavior, battle sores, mold and dull eyes should remove the fish with a net and placed in a sickbay until it is ready to be reintroduced.
There are several ways to breed catfish in a controlled environment, to achieve this you must first identify the mature male/female. The mature male have a small protrusion in the lower abdomen, large flat head and darker coloration, while the female is devoid of the protrusion.
It is possible to achieve spontaneous spawning by introducing 4 Mature females and 2 matured male in a controlled environment or separate pond. A gradual rise in water up to 100 times the present level may induce the catfish to spawn overnight. This method is unreliable and usually have a lowly 20 percent success.
Semi artificial reproduction
Semi artificial reproduction through hormone treatment is a good method to spawn catfish. There are many hormone drugs that are very effective like D O C A 5mg- 100mg, H C G hormone 2.5 - 100mg and the very effective pituitaries.
The female is injected with the hormone then placed in a separate tank with the male at a ratio of 2 females to 1 male raise the water level and spawning takes place at night. Remove the adult fish from the tank the eggs with hatch within 3 - 4 days at a rate of about 5000 fry to 1 female. Some people kill the female by cutting out the the eggs and introducing the males sperm to achieve artificial fertilization
Catfish farming is easy but takes patience and time. It can be done full time or part time. With adequate feeding of not more than 2 time a day they grow well. Please remove any excess food from water. Change the dirty water regularly and use the correct size pellets. In some parts 1 kg goes for $4. It take only 4 moths to attain this weight. I have been into catfish farming for over 8 years with great results.Catfish farming when done properly can be a good source of income why not give it a go .
