Sick Catfish

If you notice signs of disease in your catfish, don’t panic. I understand how it feels, and seeing your profit go down the drain isn’t something to be joyful about for any entrepreneur. I wrote a blog post on “How to Detect Catfish Diseases Early and Save Your Farm from Losses“, so this is part two, which discusses easy-to-get and fast Catfish disease remedies for some of these Catfish diseases.

Listed below are five fast Catfish disease remedies that have worked for me and other experienced farmers. They will help stabilise your fish and prevent further losses.

1. Salt Treatment (Natural and Effective for Many Diseases)

Salt is one of the most affordable and effective ways to treat bacterial infections, fungal infections, and parasites. I’ve used it many times, especially when my fish start showing signs of stress, red patches, or not showing responsiveness and drooping.

How to Use: This depends on your discretion too

Dissolve 1kg of non-iodised salt in 1,000 litres of water (for large ponds).
If using a concrete pond, spread salt evenly over the water-surface pond. Alternatively, spread it thinly in the tanks or place the sick fish in a salt bath (add salt to a separate tank and dip the fish for 10-15 minutes).

Know that too much salt can harm your fish. Use only when needed.

2. Potassium Permanganate (For Fungal & Bacterial Infections)

This one saved a person’s farm not too far from mine when a fungal infection was rampant. A pond with older Catfish experienced a decline in the number of fish and had to dispose them quickly (by selling them), so they pumped the water out into the river. The contaminated water entered the ponds of other people, which contained juveniles, and they had not developed sufficient immunity to withstand or fight off such a high level of bacteria and infections; as a result, the population began to decline.

That was when I learnt about Potassium permanganate (PP), a powerful disinfectant that helps kill bacteria, fungi, and external parasites.

How to Use:

Mix 2-4 grams of potassium permanganate per 1000L of water.
Spread evenly across the pond.
Let the fish stay in the treated water for 4-6 hours, then do a partial water change.

Caution: Never overdose on PP, as it can burn the fish’s gills. You can even run it for 30 Minutes and flush out the water so new water can come in. 

3. Aloe Vera or Bitter Leaf Extract (For Stress & Bacterial Infections)

Plants play an essential role in improving aquatic environments. I watched an informative video and did some research, which showed that many people support the benefits of this natural partnership. I saw a group of stressed fingerlings dealing with minor health issues. Adding specific plants could help them feel better and create a healthier environment for their growth.

Aloe vera and bitter leaf have natural antibacterial properties that boost immunity and heal wounds.

How to Use One of These Catfish disease remedies:

Blend treated fresh bitter leaves and aloe vera gel 

Add the extract to your pond once a week as a preventive measure.
For sick fish, soak them in a separate tank with the extract for 20-30 minutes.

4. Lime or Alum (For Water Purification & Disease Prevention)

We understand that poor water quality can be a major cause of disease outbreaks, mainly because that’s their everyday living environment. Water to humans is a natural remedy for human beings, so also are natural Catfish disease remedies.

If you find yourself facing issues like cloudy water, unpleasant odours, or elevated ammonia levels, it’s important to know that you’re not alone.

You might consider using lime or alum, which can help purify your water and bring back its clarity and freshness. Your health and well-being matter, and there are solutions to ensure you have access to safe drinking water.

How to Use:

For lime: Add 1kg of agricultural lime per 1000L of water to reduce acidity and kill harmful bacteria.
For alum: Dissolve 50-100g of alum per 1000L of water to settle dirt and purify the pond.

Don’t overuse (test the pH of your water before applying)!

5. Garlic and Ginger Extract (Boosts Immunity & Fights Internal Parasites)

People include garlic into their fish feed. The strong, potent blend harnesses the natural antibacterial and antiviral properties of garlic along with the anti-inflammatory benefits of ginger. Together, they not only enhance immune function but also effectively help fight internal parasites, bacterial infections, and stress-related illnesses.

How to Use:

  • Blend garlic and ginger into a paste.
  • Mix with pellet feed and allow it to dry before feeding the fish.
  • You can also mix a small amount of garlic juice into the pond water for added protection.

Conclusion

Early detection is key, but taking action fast is what will save your fish and your profits. These five Catfish disease remedies have worked for me and many other farmers:

  1. Salt treatment: Great for parasites and stress
  2. Potassium permanganate: Powerful disinfectant for fungal infections
  3. Aloe vera/bitter leaf: Natural antibacterial and stress reliever
  4. Lime/alum: Cleans and purifies pond water
  5. Garlic/ginger extract: Boosts immunity and fights parasites

If you’re dealing with a disease outbreak, start with the simplest method (like salt or garlic), then move to stronger treatments if needed. Have you ever treated catfish diseases before? What worked for you? Let me know in the comments!

How to Detect Catfish Diseases Early and Save Your Farm from Losses

By

In catfish farming

If you’ve been in the catfish farming business for a while, you already know that diseases can wipe out months of hard work in just a few days. Many farmers only realise their fish are sick when it’s too late; by then, the mortality rate is high, and profits are lost.

But what if you could spot Catfish diseases early and stop them before they destroy your farm?

In this post, I’ll show you how to detect catfish diseases before they spread, allowing you to take action quickly and avoid significant losses.

1. Watch How Your Fish Eat (Or Don’t Eat)

One of the first signs of sickness in catfish is a change in their feeding behaviour. Healthy catfish are always active and rush to eat when you feed them. If you notice that your fish are:

Eating less than usual
Ignoring food completely
Picking at food but not swallowing

Then you already know that something is wrong. This loss of appetite is a red flag that your fish might be battling an infection or poor water conditions. So, act fast by checking the water quality and observing other symptoms.

7 Unspoken Rules for Thriving in the Catfish Farming Business

By

In business tips, catfish farming

In my journey as a catfish farming business owner, I’ve seen farms rise and fall. I’ve talked to fellow farmers, learnt from my own mistakes, and discovered that while everyone has their own approach, some rules make the difference between profit and frustration.

If you’re doing this for fun, you can skip these rules. But if your goal is to build a profitable, sustainable catfish business, whether in Nigeria, Ghana, the U.S., or anywhere in the world, then pay attention to this blog post.

Here are seven unspoken rules that can help you succeed in the catfish farming business.

Rule #1: It’s Not About Big Fishes, It’s About Big Profits

Many new farmers think, “The bigger the fish, the bigger the money.” Not necessarily. What truly matters is the profit per cycle and how much you make after deducting costs.

For example, if you grow catfish for six months and end up barely breaking even, then what’s the point? Instead of just focusing on fish size, calculate your cost-to-profit ratio and optimise it.

The goal isn’t just to grow your catfish; it’s to grow profit, which will lead to a profitable catfish farming business.

Starting a catfish business? Do you handle yourself or hire others?

By

In business tips, catfish farming

Starting a catfish farming business comes with many decisions, but one of the most critical is whether to personally oversee operations or delegate from the start.

Many new farmers believe they can simply fund the business, hire workers, and watch the profits roll in. But those who have built successful farms will tell you that this is the quickest way to fail.

Why You Should Handle It Yourself:

1. Learning the basics through practice

One of Nigeria’s well-known catfish farmers, Bamidele Onibalusi, often shares how he learnt the fundamentals of catfish farming, not by reading books alone but by getting his hands to work on the farm. He started with small ponds, followed experienced farmers, asked countless questions, and observed every tiny detail of fish growth, feeding, and pond preparation. More than just learning how to raise fish, he understood what it takes to run a farm like a business. 

It’s always best advised that you start a business by learning the basics and practising all that is learnt.

2. Understanding long-term farm management

Successful catfish farming requires more than just capital. It demands knowledge, experience, and the ability to anticipate problems before they become disasters. A hands-on approach in the beginning helps you develop a deep understanding of your farm.

You will observe how the fish behave when they are well fed versus when they are stressed. You will know how water quality affects their growth and why certain feeding patterns yield better results. Being on the farm teaches you how to identify diseases, spot unhealthy fish, and manage daily operations without relying solely on employees.

Farmers who have built strong businesses in the industry started by immersing themselves in the process. They learnt how to handle problems firsthand, which later made it easier to train workers properly and identify inefficiencies.

3. Avoiding scams and financial losses

One of the biggest risks in outsourcing your farm management too early is falling victim to scams or unnecessary expenses. Many business owners pour money into solving problems that don’t actually exist. Workers may exaggerate the cost of feed, medications, or pond maintenance, knowing that the owner has no way of verifying the claims. Others might mismanage funds, leading to huge financial losses before the business even takes off.

There have been cases where farm owners kept funding water system repairs, restocking fish, or increasing feed expenses based on misleading reports, only to realise much later that the farm’s issues were never about funding but about poor management.

Avoid These 5 Catfish Farming Mistakes to Maximise Profit

By

In business ideas, catfish farming

I’ve been in catfish farming for over eight years, and if there’s one thing I’ve learned, it’s one thing to read about catfish farming and another to get your hands dirty and do the work. In Africa, especially in Nigeria, catfish farming offers huge opportunities with constant demand from restaurants, markets, and private buyers. However, avoiding these Catfish farming mistakes is key to turning this demand into profit.

Whether you’re new or experienced in catfish farming, this guide will reveal the top 5 catfish farming mistakes that can impact your profits and how you can avoid them for long-term success.

5 catfish farming mistakes to avoid:

1. Starting Big Without Experience

When I first ventured into catfish farming, I learned pretty quickly that starting big isn’t the way to go.  A friend of mine went all out and threw 1,200 fingerlings into one pond, thinking he’d make a ton of money right away. But just three months later, he lost almost 40% of the fish because of overcrowding and not knowing how to manage water quality and feeding properly.  

When you are just starting, considering the costs of setting up ponds, feeding, buying fingerlings, and investing your time and energy, you want to run a smaller operation. For instance, setting up ponds and feeding about 500 fingerlings can cost anywhere from around ₦450,000 to ₦500,000. You might want to read this interesting and informative blog post about feeding and Catfish Farming. Step 3: Feeding Your Fishes. 

2. Neglecting Market Research: How to Sell at the Best Price

Here’s a hard truth I learned early: growing catfish is the easy part; selling them is where the challenge is, especially when you don’t get your calculations right and fail to get very good profits during sales. Many farmers, myself included, make the mistake of focusing solely on rearing the fish without planning how to sell them effectively. So, get to understand who will buy your fish, how to price them, and whether to sell them live or processed.

When I first started, we didn’t fully understand the market. Most especially the times when our fish were ready for harvest, we would let the buyers dictate the price. Because we were desperate to sell, we ended up selling at a loss just to clear the stock or not make enough profit to run the next batch. So, don’t make the same mistake; check below to understand the calculations better. 

Calculation Example:

Let’s say you stocked 2,300 fingerlings in a pond and spent a total of ₦1,000,000 on your farm operations for six months. This amount includes:

  • Cost of fingerlings: ₦92,000 (₦40 per fingerling).
  • Feeding costs: ₦800,000.
  • Other expenses (pond maintenance, labour, medications): ₦108,000.

Now, let’s assume you have 2,000 catfish left after accounting for sorting, mortality, and grading. Each catfish weighs an average of 1.2 kg, giving you a total of:

2,000 fish × 1.2 kg = 2,400 kg of fish ready for sale.

Images of selling catfish

Scenario 1: Selling Without Calculations

A catfish marketer offers you ₦1,200 per kg, and you agree to the deal without calculating your actual costs or potential profits.

  • Revenue: 2,400 kg × ₦1,200 = ₦2,880,000.
  • Profit: ₦2,880,000 – ₦1,000,000 = ₦1,880,000.

At first glance, this looks profitable. However, let’s say another buyer was willing to pay ₦1,800 per kg. By not exploring the market, you’ve lost an additional ₦600 per kg, which translates to:

  • Missed Revenue: 2,400 kg × ₦600 = ₦1,440,000.

You just left a lot of money on the table simply because you didn’t negotiate or know the market well enough.

Scenario 2: Selling at a Loss

Now imagine you’re desperate to sell, and the marketer insists on ₦900 per kg. You accept the offer because you didn’t plan for alternatives.

Feeding Catfishes in the pond

As a seasoned catfish farmer in Africa, I’ve experienced the thrills and rewards of the industry firsthand. My journey began with a personal passion for aquaculture, starting with a small cement pond in front of our house and eventually expanding into larger earthen ponds. Over the years, I’ve uncovered numerous profitable opportunities in catfish farming, from direct sales to value-added products.

In this blog post, I’ll share my insights and experiences on the ten most lucrative opportunities in catfish farming. With practical tips, real-world examples, and statistics, I aim to help both seasoned farmers and newcomers maximise their earnings and make informed decisions.

1. Direct Sales: 

Direct sales remain one of the most effective and profitable opportunities in catfish farming. This approach involves buying juvenile catfish, raising them to market size, and selling them directly to local markets, restaurants, or individual consumers. By selling in bulk, you create a steady income stream and build strong customer relationships.

In my experience, selling catfish to local buyers who purchase in bulk, restaurants, and supermarkets has been highly successful. You just need to ensure that proper management practices are carried out to ensure that catfish reach harvest size within 6–8 months, and selling in bulk helps maintain a steady cash flow.

Feeding Your Catfish in Cement Ponds: Practical Tips for Optimal Growth

Catfish feed

Feeding your catfish properly is a one-way and effective way to get the desired fish size growth and also the turnout of profit, as well as a way to notice the behaviours and health of the fishes and their overall productivity. Having managed both cement and earthen ponds, I’ve gained valuable experience in optimising feeding strategies, especially in cement ponds where controlled environments require specific approaches, and I can beat my chest to say that if you don’t get the feeding right, it could cost you a lot of money.  In this post, I’ll share practical tips and insights on feeding your catfish in cement ponds to achieve excellent sizing results.

We already covered my experience using Cement Ponds vs. using Eathen Ponds and building your own cement ponds in this blog post but today’s article will provide practical tips and insights on feeding your catfish in cement ponds to achieve excellent sizing results.

1. Understanding Catfish Feeding Behaviour:

My Observation:

One of the first things I learned was the importance of observing my catfish during feeding times. Before, I used to wonder why people spent so much time during and after feeding. However, when we started our fish farming, we would stroll to the farm to watch the fishes and how they were behaving. During these times, we were able to notice wounded fish or fish that were not swimming properly, consistently putting their heads up, indicating low water oxygen levels, among other things, all while we were feeding them.

In cement ponds, catfish behaviour can differ slightly from earthen ponds due to the more artificial environment. So, pay attention to how they respond to different feeds and feeding times. For instance, I noticed that my catfish were initially hesitant about floating pellets. Some fish were shy, staying at the bottom, while the more aggressive ones quickly dominated the feed. Adjusting feeding strategies to ensure all fish had access to food was essential for uniform growth.

Cement vs. Earthen Catfish Ponds: Which is Better for Your Aquaculture Business?

Cover imagery Cement vs Earthen Ponds

When I started my catfish farming business, I had to make an important decision: should I use cement or earthen ponds? At first, I chose a cement pond due to its reputation for offering a controlled environment and being durable. However, as my business grew and changed, I switched to earthen ponds. In this post, I want to share my personal experiences with using both types of ponds, including practical aspects and nuances that could affect your aquaculture decisions (Cement vs. Earthen Catfish Ponds).

What is Concrete Cement Catfish Farming?

Concrete Cement fishes inside water


Concrete cement catfish farming involves growing catfish in cement ponds instead of natural bodies of water or earthen ponds. These cement structures, often rectangular or square, are tailored to fit the size of the farming operation. The popularity of cement ponds in aquaculture is rising due to their efficiency and the increasing demand for fish protein.

Why I Settled for Cement Ponds Initially:

My journey as an entrepreneur did not begin with fishery farming. However, after running a customised sweatshirt business in school and freelancing after graduation, I turned to fish farming. My mother’s success inspired this decision in scaling her poultry farm and the achievement of a local earthen pond farmer near my house. I was encouraged by my family to venture into catfish farming and decided to construct a 500-square-meter cement pond at the front of our home.

This decision was strategic, as a cement pond was a better option for beginners in catfish farming. If there was a huge loss, our costs of setting it up would be reduced compared to renting an earthen pond. We also had the cement pond to ourselves, and it could be converted into other things. Additionally, it offered a high level of control over environmental variables such as water quality and temperature.

GET PRACTICAL INFORMATION ABOUT CATFISH FARMING: Due to a VERY BUSY schedule, I haven’t been able to update the series on catfish farming or respond to comments, but I have something better for you; you can learn directly from my teacher, who has recorded up to 120% profit in 6 months. Visit Profitable Fish Farming to learn directly from him!

By principle, I rarely venture into businesses that do not have a high profit margin; I’m talking at least 50% or more within 6 months to 1 year, depending on how big my investment is.

Whenever new business ideas are introduced to me, I make it clear that unless I can have a 100% profit margin within a reasonable period, I won’t get into that business.

I’ve been a commercial catfish farmer for over a year now, and it is one highly profitable business; having a 50% profit margin within a span of 6 months is normal, if you do things right, and having a profit margin of 150%+ within this same period is not unusual.
