As we look ahead, the future of catfish farming in Nigeria holds promise and potential, thanks to the visionary support of the government.
Entrepreneurship has become a household name, especially in Nigeria. This is obvious in the searches available in Google Trends in the past 12 months having 100% search between April 7-13, 2019, and of recent 82% search on February 9-15, 2020 (https://trends.google.com/trends/explore?geo=NG&q=Entrepreneurship).
The talk around the subject of entrepreneurship has always been about the opportunities that abound.
Nevertheless, while there are opportunities there are also challenges that come with the terrain and these challenges can be a bit more magnified for newcomers especially if they don’t get mentored by more experienced entrepreneurs.
Highlighted below are some avoidable challenges new entrepreneurs should know and avoid
Lack of understanding of the position of money in business: Money is needed in business no doubt! But, what is the use of money if the skills needed to manage it is lacking. Better still, what does a soldier need most: arms and ammunition or military skills? Of course, the military skills because it gives the soldier an advantage in the war front over every other soldier without skills. The skills such as business skills, negotiating skills, and resourcefulness needed to run a business is more important than money.
Lack of Personal Development: To remain relevant and up to date with the trends as an entrepreneur you have to prioritize personal development. For newcomers in entrepreneurship, personal development could be having a mentor, buying books, taking online courses, attending workshops, etc. Investment in personal development is a good investment and it helps an entrepreneur to build systems for learning which results in efficiency in the production of goods and services.
Being too busy for Proper Cash Flow Management: An average entrepreneur has the mindset that as long as he/she is making sales and he/she is the one managing and handling money then there is no need for proper cash flow management. However, proper cash flow management is more than just handling money. It is an accounting system that shows all the business transactions of a business and it is used to aid decision-making. Cash flow in its simplest definition is the inflow and outflow of cash in the business.
Overlooking collaborative Entrepreneurial environment: We are living in a fast-paced world and it is a matter of wisdom for winning in business to understand that collaboration is the way forward not competition. As a newbie, you will accomplish more if you leverage the strengths of existing businesses through partnerships. However, make sure all your partnership arrangements are documented.
The fear of “what if” Robert F. Kennedy said, “Only those who dare to fail greatly can ever achieve greatly.” Being an entrepreneur has its own attendant challenges such as betrayal, rejection, and failure. The fear you have is common to all men, what makes the difference is what fear drives you to do. Newcomers to entrepreneurship should understand that there is no end to “what if” in the course of the entrepreneurship journey and that is what makes entrepreneurship look more like an adventure. Dare to face your fear head-on!
Improper Use of Social Media: Social media is a great marketplace! However, many newcomers in entrepreneurship spend a lot of time on social media putting up a front different from reality instead of developing their crafts. The truth is that customers buy value hence, if your ‘social media’ promise is not the same as your delivery you will lose your customers.
Finally, challenges in entrepreneurship did not start today. Hence, as an entrepreneur, you have to be proactive and this means that you have to anticipate these challenges and make adjustments to mitigate them.
Nigeria has a vast expanse of inland freshwater and brackish ecosystems that encourage fish farming, an enterprise that has endless possibilities to contribute significantly to the country’s Gross Domestic Product (GDP), creating job opportunities and generating income that can lift rural farmers out of poverty.
With a population of over One hundred and Ninety million people, Nigeria is the largest fish consumer in Africa and among the largest fish consumers in the world, with over 3.2 million tons of fish consumed annually. Yet, the country imports over 2 million metric tons of fish because of its limited domestic catch, and a total of 1.1 million metric tons of fish were cultured. Consequently, the country depends largely on the importation of frozen fish, resulting in an annual expenditure of N125 billion on fish imports. The limited knowledge of best management practices in aquaculture, limited access to quality feeds and fingerlings, access to finance, and insufficient market outlets; all contribute to the low output from the fish enterprise.
key aspects that can be enhanced in Nigeria’s catfish farming business
Nigeria’s catfish farming industry has experienced significant growth in recent years, contributing to the country’s economic development and providing a source of livelihood for many. However, there are still areas that require attention and improvement to ensure sustainable and profitable operations for catfish farmers. We’ll delve into some key aspects that can be enhanced in Nigeria’s catfish farming business.
Quality Breeding Stock: One of the critical components of a successful catfish farming venture is starting with high-quality breeding stock. By investing in genetically superior fish, farmers can ensure better growth rates, disease resistance, and overall productivity. Government agencies and private organizations can collaborate to provide access to certified breeding stock and promote best practices in breeding management.
Improved Water Quality Management: Maintaining optimal water quality is crucial for the health and growth of catfish. Regular monitoring of water parameters such as pH, dissolved oxygen, and temperature is essential. Farmers should be educated on effective water treatment techniques and filtration systems. Additionally, the government can establish guidelines for sustainable water use to prevent over-extraction from natural sources.
Feed Formulation and Management: Developing cost-effective and nutritionally balanced feed is paramount for profitability in catfish farming. Research and development efforts should focus on creating locally sourced, high-quality feed options. Training programs and workshops can be organized to educate farmers on efficient feeding practices, including feeding schedules, portion sizes, and feeding frequency.
Disease Management and Biosecurity Measures: Disease outbreaks can have devastating effects on catfish farms. Implementing strict biosecurity measures, such as controlled access, quarantine procedures, and disinfection protocols, can help prevent the introduction and spread of pathogens. Education on disease identification and treatment should be readily available to farmers, along with access to veterinary services.
Market Access and Value Chain Strengthening: Connecting catfish farmers with reliable markets and establishing strong value chains is essential for sustainable business growth. Cooperative societies and farmer associations can play a vital role in negotiating fair prices and ensuring market access. Additionally, promoting the processing and value addition of catfish products can open up new revenue streams for farmers.
Technology Adoption and Data-driven Decision Making: Embracing modern technology, such as automated feeding systems, water quality monitoring devices, and data analytics tools, can significantly improve farm efficiency and productivity. Encouraging farmers to adopt these technologies through training and financial incentives can lead to more profitable and sustainable operations.
Regulatory Support and Policy Reforms: Government agencies should work closely with industry stakeholders to create a conducive regulatory environment for catfish farming. This includes streamlining licensing processes, providing access to subsidies and grants, and enforcing environmental sustainability standards. Policy reforms should aim to address the challenges faced by catfish farmers and promote responsible farming practices.
Conclusion:
By focusing on these key areas, Nigeria’s catfish farming industry can achieve higher levels of productivity, sustainability, and profitability. Collaboration between government agencies, research institutions, private organizations, and farmers is crucial for implementing these improvements. With concerted efforts, Nigeria’s catfish farming business can continue to be a driving force in the country’s agricultural and economic landscape.

Stay tuned to our blog for more tips, insights, and success stories from the world of catfish farming in Nigeria.
If you are starting a fish farming in 2023, things have changed. The world has changed. Agriculture has changed. The way we used to farm before has changed. Yet Fish farming remains a profitable and safe venture for new entrants into agriculture. Here are 7 tips to keep an eye for as you start your fish farm.
Let us dive in and discuss 7 questions you should answer before you start a fish farm in 2023.
1. Start with the market or sales target.
The world is a global village now.
You can decide to export your fish. The requirements of NAFDAC mean that you should let the decision of your target market influence the setup of your farm.
If you want to export your fish you know that your ponds water source must be controlled. You cannot use runoff water for the farm. You would need a borehole that can be tested.
If you are raising over 20,000 fish, you know that you would need those clients who buy fish in tonnes. They would always bring buses, so you need parking space close to the ponds. You would also prefer earthen ponds because you would be keeping the fish for at least 7 months.
But if you are doing about 10 thousand fish, you can do mobile tarpaulin fish ponds. You can stagger your fishes because you would sell your fishes little by little rather than the whole pond at once.
To know the number of fish you can raise. Use 700naira as a cost price to raise one fish to 1kg.
That means 1000 fishes is 700,000. Oya realistically, how many fishes can you raise to 1kg?
Please don’t start a farm and then stop short because of funds. It would make you under pressure and then sell at a loss price because you don’t have the funds to continue to feed the fishes.
Start small and let the farm grow.
2. Secure your water.
As I said earlier, water is one of the 3 most important things in fish farming.
It is called Aquaculture for a reason.
Water cannot be rationed, it cannot be managed. You need a borehole or a running stream or a swamp to ensure you have running water year-round.
Water should always be readily available.
Discuss with your borehole guy, you need an industrial borehole. It must support a 2-horse power pumping machine and at least a 2-inch pipe coming out from the borehole. I am serious! It is better we have one very good borehole than have 3 small insufficient boreholes.
3. Use production target to determine ponds type and size
There are different fish pond types and they best suit different fish farming activities.
There are tanks, earthen ponds, fiberglass setups, concrete ponds, mobile fish ponds, and recirculatory systems.
Fiberglass setups and recirculatory systems are usually best for fish hatching and the creation of juveniles and fingerlings.
Mobile ponds, Concrete ponds, and Tanks are best for mélange and smoking-sized fish.
Earthen ponds are best for table size fishes and broodstock.
When starting a fish farm in 2023, make sure you calculate your stocking density.
You should know the exact number of fish to put in each pond.
A 10*10*4ft mobile pond would take about 800 fish.
The smallest earthen pond you should do for growing out fishes should be 50ft*30ft depending on water availability. That can take about 500 fish.
4. Innovation: What is your advantage?
Please know that every farm is different, yet every farm is the same business.
As you are coming into the fish industry, what is your comparative advantage?
Is it that you are closer to your consumers so you can serve them better and fresher fish?
Is it that you are close to a water source and so water which is one of the three most important factors in fish farming is not a challenge to you?
Can you use Solar to power your pumping machines rather than a fuel-powered generator?
Would you think of reducing labor costs by deploying an Automatic Fish Feeder and thus your product is cheaper?
Are you thinking of Climate change and its challenges in you starting the fish farm in 2023?
5. The almighty Feed issue
Fish feed should be about 70 percent expense on a well-set-up fish farm.
If you set up your fish farm properly then you should have feed expense, water change, cost of fingerlings and juvenile, and cost of labor (staff salaries) as your topmost expense in your fish farm.
Now I know that you have heard that you can make your own feed, it is true.
And I do make my own feed in some farms; however, I don’t make my own feed in all of my farms.
Some of the farms are not big enough to make that venture worth it.
I personally advise that if you are not doing 10,000 fish and above you shouldn’t bother with fish feed-making machines.
The money you would use to buy and run those machines is higher than what you think you would save from buying a normal branded feed.
There are good and economic fish feeds available right now.
See this article where I talked about how to make a decision on which feed to use in starting your fish farm in 2023.
You can use either imported fish feeds like Skretting and Coppens or made in Nigeria feeds like Vital, Top, Bluecrown or Ecofloat feeds.
6. Fish Processing the superpower
Please, as you are starting a fish farm in 2023, factor in fish processing. This is dried fish or smoked fish depending on whatever you call it.
Smoked fish brings more proft.
It increases your profit by about 13 percent.
You would need a fish smoking kiln, some materials such as sealing machine and nafdac grade nylons and you are good to go !
7. The Source of your Juveniles or fingerlings
This is a big issue that either makes or mars fish farms that are just starting.
Some people unknowingly buy runts and keep feeding and feeding and the fish don’t grow.
This is not always the case as there are other factors that make fish have stunted growth e.g overcrowding or poor feed.
But buying runts as fingerlings is a real possibility for anyone starting a fish farm in 2023. The best way to avoid this is to buy fish only from a reputable fish hatcher.
The truth friends is that there is a lot of politics going on in and around our environment that can either be support or hindrance to starting our fish farm.
Government Agencies, Grant and Loan applications, and processes, digital empowerment can be an addition or a blessing to a farm.
Even your staff on the farm can be a hindrance to your business.
I like to put accountability structures when doing business with family.
I trust you as my brother o, but let’s just have proper record-taking for accountability’s sake so that we can show our records to people that can give us a loan or grant sef. You Gerrit?
In 1976, the Netherlands became the first country in Europe to import African catfish. 40 African catfish imported from the Central African Republic to the Netherlands served as the initial broodstock. In recirculating aquaculture systems, commercial cultivation of this species began around 1985. (RAS).
Israel and South African catfish strains were imported much later. The “Dutch strain” of African catfish, which is now being cultivated, was created by crossing these strains in order to produce fingerlings.
On a farmer’s level, choosing brood stock is often done in a rather simple manner. It is highly expensive to maintain and strictly separate large populations of several African catfish strains over extended periods of time. If you are successful, the effects become apparent after a few years. For the commercial farmer, the next challenge is to maintain this edge for himself.
The need to demonstrate to his client the advantages of a superior strain is another challenge for the farmer raising African catfish fingerlings. In the eyes of a researcher, increases in growth and feed conversion ratio of, say, 5% are major accomplishments, but for a farmer, these improvements represent modest variations that are likely to go unnoticed without rigorous farm records.
Practically speaking, pricing is the primary factor influencing the market for fingerling African catfish. The availability, size, consistency, and health state of the African catfish are all priorities for hatcheries.
The majority of African catfish farmers (in the tropics and in Europe) are small to medium sized, poorly organized, and lack the resources and skills necessary to do meaningful research on genetic enhancements of their stocks. Universities have conducted the scant genetic study on African catfish, but it has never been taken seriously in reality.
Selection of African catfish broodstock
The production of African catfish is a relatively recent business. It began in Europe in the early 1980s, and at that time, only few farmers in Africa were engaged in widespread farming activities.
Picture of a ready-to-spawn African catfish broodstock
The initial broodstock originated in the wild. For instance, wild African catfish were imported into the Netherlands from Central Africa, and the first selection was made primarily on size. In my perspective, we were just selecting fish that could adapt to the intense farming methods used in warm water recirculation systems. Fish were brought in from Israel and RSA not long after the arrival of African catfish from Central Africa. The “Dutch African catfish” is a product of three strains since the strains were not maintained distinct in the Netherlands.
The processing business places a great deal of importance on the quality of the meat and the proportion of dress out. The strains from various parts of Africa differ from one another. Because fish is consumed whole in the tropics—no filets are removed from the fish, and heads and guts are not wasted—the element of flesh quality and dressing proportion is less significant.
Africa catfish hybridization Heterobranchus and Clarias species interbred to create intergeneric hybrids, which are animals that belong to the Siluriformes order of animals (Ref.). The so-called “Hetero-clarias” is a well-known intergeneric hybrid created by mating a male Heterobranchus longifillis with a female Clarias gariepinus (see figure 5). The intergeneric hybrids exhibit traits from both parental species as a result of rearranging genetic material from both parents in the child.
For a group of farmers connected to a processing factory, we are raising this hybrid in our hatchery in the Netherlands. This group is particularly committed to raising and selling this kind of fish. Heteroclarias filets are white in color as opposed to Clarias gariepinus filets, which are pink or reddish, and have 30% more fat, which enhances the flavor. In hybrids, the gonads are essentially nonexistent and inactive. Because of this, the dressing % is higher than it would be for Clarias gariepinus. White filets from marine fish species can be substituted with the Heteroclarias fish filet.

benefits of hybridizing catfish As a producer of Heteroclaria fingerlings, we see significant behavioral variations from the common African catfish. When frequent grading is ignored, the Heteroclarias fingerlings exhibit extreme cannibalism and exhibit a broad range of development. The Heteroclarias is readily strained in comparison to this. Well-graded fish exhibit highly equitable development and low mortality to the point of harvest at 1.4 kg at 12 weeks of age.
In the tropics, Heteroclarias is regarded as a better growing fish and is preferred over Clarias gariepinus for pond cultivation.
A producer of fingerlings will greatly benefit from hybridization. Because the hybrids are sterile, buyers cannot use those fish to continue reproducing. Pure parent stock is always kept on-site and never distributed to other farms. As compared to Clarias gariepinus, the pure Heterobranchus longifillis strain develops at a fairly late age of 2 years (1 year).
Upkeep of the African catfish broodstock To obtain high-quality eggs and sperm, good brood stock maintenance is required. To have traceability for each batch of progeny and the potential for a breeding program, the broodstock should be individually branded. With the use of individual tagging, it is feasible to keep accurate records and ensure that the broodstock is given adequate time to recuperate after spawning.
For obvious reasons, broodstock should be kept apart from other farm activities:
To protect them from stress and illnesses
To achieve a year-round reproductive cycle, they must optimize their environment through a consistent light regime and consistent water quality.
We prefer recirculation systems in a confined area with temperature control if necessary. In the tropics flow through systems can work too if flushed with good quality borehole water.
Productivity of female broodstock
In our farm, the productivity of the female (fecundity) expressed as a percentage of the body weight is between 5-15%. The egg size tends to increase with the size of the female. In larger fish, the number of eggs per gram of eggs is lower than in smaller broodstock. On average, we count 500 eggs per gram. The average females we are using in our farm have a weight of 6 kg and produce 300-600 grams of eggs per female which equals to 150.000-300.000 eggs.
Egg production of African catfish
A female fish is selected from one of the broodstock fish tanks. With a small tube, it is possible to sample the eggs out of the ovaries to check if the nucleus has migrated to the side and if the egg size has a diameter of 1 mm or above. Most farmers do not perform this check as they just select by eye.
In captivity, females do not perform the final ripening of the eggs without hormonal treatment. The injection of gonadotropin-releasing hormone in the form of natural pituitary glands or synthetic products like OVAPRIM induces the final step of ripening called vitellogenesis. In this final step the eggs are provided with yolk and take up water.
The period between injection with hormones and stripping of the eggs depends on the temperature of the water and the type of hormone used. Through trial and error, the perfect time for stripping can be determined. Too early or to late stripping results in bad egg quality and thus poor spawning results.
Too early stripping results in a very dry egg mass. It is difficult to completely strip the female because the eggs do not flow out. The female often dies because of stress and internal injuries.
Too late stripping results in a fluid egg mass. Often the female already released a lot of eggs in the preparation tank but stripping is very easy.
Stripping an African catfish female
Several hours after stripping we perform final stripping to remove all ripe eggs from the ovaries of the female. This is to prevent that these ripe eggs die inside the ovaries and start to deteriorate. This will harm the fish and can cause death of the broodstock female. The females have to stay in recovery for a couple of days before putting them back to the broodstock tank.

Sperm Harvesting
Male African catfish do not release sperm after treatment with hormones like many other fish species. The males have ripe sperm all year round. The fish should be at least 1 year old to have ripe gonads. A lot of variation can be seen between males of the same age in the ripeness and size of the testis. In practice, farmers sacrifice males in order to dissect the testis out of the abdomen. By making incisions in the testis tissue the sperm can be collected. As a consequence new male broodstock needs to be added to the broodstock population sacrificing the males is a big constraint on genetic programs.
Some farmers are using operations on the males. After tranquilizing the fish, a small incision is made in the belly of the fish, and with a syringe with needle, some sperm is taken out of the testis. Finally, the incision in the belly is stitched using veterinary stitching material and the male is able to recover in 1 to 2 weeks. During this time the wound closes completely.
Unlike the sperm of mammals sperm of fish is not active, but will become active as soon as it is in the water. The sperm is active for less than a minute, so it has to find an egg quickly before all the energy has gone. This is the reason that during the process of sperm collection all materials, hands, and fish should be dry. Although these precautions are taken, the sperm can be activated accidentally. The sperm concentration of good males is more than a million per ml!
Fertilization of African catfish
The eggs and sperm are collected in a dry glass or porcelain bowl and a dry small glass or porcelain cup respectively. A simple but effective way of fertilization is to bring the eggs and sperm together in the egg collection bowl and mix it gently before adding water.
In literature adding certain fertilizing solutions during fertilization is reported as being very beneficial because they are thought to extend the life of the sperm in order to improve the fertilization rate. I prefer not to use any extra fluids because any extra handling can give a problem too.
Artificial propagation of African catfish is a relatively simple procedure and many farmers are very skillful in doing it. Millions of larvae are hatched weekly in a country like Nigeria but until today there still is a shortage of good-quality fingerlings and juveniles. Reproduction of African catfish is following a certain procedure, but farming the larvae for 1 or 2 months to the juvenile stage comes down to the capabilities of the individual farmer.
Catfish are one of the oldest and most widespread fish species, adapting well to their environment. They thrive worldwide, with the exception of some places with extreme temperatures. This article details the nutrients, benefits, and downsides of catfish.

It is packed with lean protein, which is essential for building and repairing tissue and muscle, as well as for hormones, enzymes, and other molecules.
One 3.5-ounce (100-gram) serving of catfish provides 32-39% of your daily protein needs in only 105 calories, compared to salmon providing half of your daily protein needs but over 230 calories. Nutrient-dense protein sources like catfish may aid weight loss by boosting feelings of fullness.
This fish is also a great option for people who are watching their calorie count but want to make sure they’re getting enough nutrients.
Contains omega-3 fatty acids
The U.S. Department of Agriculture (USDA) recommends eating up to 8 ounces of fish or other seafood each week (3Trusted Source).
One reason for this recommendation is that catfish and other seafood tend to provide more omega-3 fatty acids than other foods (4Trusted Source).
Although more research is needed, they may even help treat neurological and mental conditions, including memory loss, attention deficit hyperactivity disorder (ADHD), and depression (5Trusted Source, 6Trusted Source).
A review of 23 studies in over 1 million people associated eating fish with an overall lower risk of death — and a 7% reduction in the chance of death for every 200 mg of omega-3s consumed daily (11Trusted Source).
Given that your body cannot produce omega-3s on its own, you need to get them through your diet. One 3.5-ounce (100-gram) catfish fillet delivers 237 mg, or 15–20% of the Adequate Intake (AI) for adults (5Trusted Source).
While catfish does provide omega-3s, it is a leaner fish that provides fewer fatty acids than a fatty fish like salmon.
A 3-ounce serving of fatty fish like salmon can contain up to 1,800 mg of omega-3s compared with a 3-ounce serving of catfish which contains only 200 mg of omega-3s (12Trusted Source).
All the same, further studies are needed on some of these benefits (21Trusted Source).
Cooking methods for catfish
Catfish can absolutely be part of a balanced diet, but cooking methods greatly influence how healthy it is.
This table examines how various cooking methods affect the calorie, sodium, and fat contents in a 3.5-ounce (100-gram) serving of catfish (22Trusted Source, 23Trusted Source, 24Trusted Source):

Though catfish is commonly fried, other cooking options result in lower calorie, fat, and sodium contents.
Compared with dry heat cooking, frying catfish in oil adds as many as 124 calories and over 10 grams of fat. In contrast, some healthy dry heat cooking methods include baking, broiling, grilling, roasting, and pan frying.
NOTE
How you cook catfish significantly affects its calorie, fat, and sodium levels. For a healthier option, stick with a dry heat method like baking or broiling.
Catfish is a low-calorie meal that provides essential nutrients such as vitamin B12, proteins, and omega-3. It is also versatile and affordable.
Catfish is a popular game fish, but it also has many nutritional benefits. It is affordable and available in the US.
These species are known for having sensory organs called barbels that resemble whiskers, making them easily recognizable. They usually live in lakes and streams, although you can also find their nests in deep pools that provide cover for the younger catfish. At night, adults move into shallower water — which is usually when fishers catch them.
People often describe the catfish taste as being milder in flavor than other fishes, similar to sweet whitefish. While this may seem like a disadvantage, it also means that catfish can easily be adapted into your diet through various recipes.
What Are the Benefits of Eating Catfish?
Catfish, like most other fishes, has valuable nutritional properties that make it ideal for sustaining a balanced diet. Paired with its mild flavor and affordable prices, catfish is a fantastic alternative to more expensive meats such as pork.
Low in calories. Catfish only has about 98 calories in a 100-gram portion, making it a great choice for people looking after their weight. This also makes it ideal for replacing other, more caloric meats such as poultry in most recipes.
Fantastic protein source. Like most fish, catfish is known for providing a lot of protein — a 100-gram serving contains 13 grams, representing 26% of the recommended daily quantity. Protein is crucial for maintaining and growing cells and tissues.
High in vitamin B12. Most people don’t consume enough vitamin B12 — a compound vital to nerve function, cell metabolism, and DNA production. Catfish is an excellent source for it, surpassing the daily recommended value in a single 100-gram serving.
Provides healthy fats. While it does have a slight amount of saturated fats, catfish also provides a good amount of healthy lipids in a single portion. Plus, fish is also known to contain omega-3 fatty acids, which help prevent heart disease, dementia, and cancer.
