How to Start Catfish Farming: A Beginner’s Guide to Profitable Aquaculture

Catfish farming is one of the most lucrative forms of aquaculture in Africa and many parts of the world. It is relatively easy to start, has a quick return on investment, and meets a growing demand for protein-rich food. Whether you’re starting on a small scale in your backyard or aiming for commercial production, catfish farming can be both rewarding and profitable—if done right.

This guide will walk you through the essential steps to get started with catfish farming.

1. Understand the Catfish Market

Before diving into catfish farming, research your local market. Understand:

• The demand for catfish in your area

• Average prices per kilogram

• Potential buyers (hotels, restaurants, market women, households)

• Competitors and existing farmers

Knowing where and how to sell your fish is just as important as raising them.

2. Choose the Right Location

The success of your farm depends on selecting a suitable site. Consider:

• Accessibility: Should be reachable by road for easy transportation.

• Water Source: A constant and clean water supply is essential—borehole, well, or stream.

• Drainage: Proper drainage is vital to prevent stagnant water, which can harbor diseases.

3. Decide on a Farming System

There are different ways to rear catfish. Choose based on your budget, land, and available water:

• Concrete ponds: Durable and ideal for controlled environments.

• Earthen ponds: Cost-effective and closer to a natural habitat.

• Plastic tanks or tarpaulin ponds: Ideal for beginners or those with limited space.

• Flow-through systems: Advanced systems that continuously supply fresh water.

Each system has its pros and cons. Concrete and tarpaulin ponds are popular among beginners due to their manageability.

4. Construct Your Pond

Once you decide on the system, construct your pond with proper drainage and inlet systems. Ensure:

• Smooth water flow in and out

• Adequate depth (at least 3–4 feet for plastic/tarpaulin ponds)

• A secure perimeter to prevent predators and escape

If you’re using tanks, make sure they are thoroughly washed and treated before use.

5. Source Quality Fingerlings

Fingerlings are young fish that you’ll raise until harvest. Sourcing healthy, active fingerlings from a reputable hatchery is crucial.

Look for:

• Active swimmers

• Uniform size

• No signs of injury or disease

You can start with 500 to 1,000 fingerlings for a small-scale farm. Avoid overcrowding to prevent stress and death.

6. Feed Management

Feeding accounts for the majority of your production cost. Use high-quality feed with at least 35% protein for growth.

Feeding tips:

• Feed twice daily (morning and evening)

• Avoid overfeeding—leftovers can pollute the water

• Use floating pellets to monitor feeding behavior

As your fish grow, adjust feeding quantity and size of pellets accordingly.

7. Monitor and Maintain Water Quality

Water is life for catfish. Poor water quality can cause disease outbreaks and slow growth. Regularly check:

• pH levels (6.5–8 is ideal)

• Ammonia levels

• Oxygen content

• Temperature (25–30°C)

Change 20–30% of the water weekly (or more frequently in small tanks). Remove dead feed and waste regularly.

8. Prevent and Control Disease

Good hygiene and monitoring reduce the risk of disease. Signs of sick fish include:

• Loss of appetite

• Lethargy

• Surface gasping

• Skin lesions or fin rot

If you notice these symptoms, isolate the affected fish and consult an aquaculture expert for treatment options.

9. Harvesting and Marketing

Catfish is usually harvested between 4 to 6 months, depending on your target weight (often 1–1.5kg per fish).

Methods:

• Drain the pond and collect the fish with nets

• Sort by size and remove dead or unhealthy ones

Sell your fish live or smoked, depending on market demand. Have a marketing strategy in place before harvesting to avoid holding costs.

10. Keep Records and Grow

Maintain records of:

• Fingerlings purchased

• Feeding schedules and quantity

• Water treatment

• Growth rate

• Mortality

• Sales and profits

These records help you improve future production cycles and ensure you’re making a profit.

Conclusion

Starting a catfish farm requires planning, dedication, and basic aquaculture knowledge. With the right setup, healthy fingerlings, and consistent feeding and monitoring, you can turn your small operation into a profitable business.

Whether you’re doing it for side income or full-scale entrepreneurship, catfish farming is a smart move for anyone looking to dive into agriculture.

How to Make Money from Catfish Farming

Catfish farming offers multiple income streams if managed effectively. The most direct way to earn is by selling mature fish after 4–6 months of growth. Depending on your scale, selling to local markets, hotels, restaurants, cold stores, and individual buyers can generate substantial profit. For example, if you rear 1,000 catfish and sell each at GH₵20–GH₵30 (₦1,000–₦1,500 in Nigeria), your revenue could reach GH₵20,000–GH₵30,000.

You can also add value by smoking the catfish, which increases shelf life and fetches higher prices. Smoked catfish is in high demand in urban areas and abroad, making it an attractive export product.

Other income sources include:

• Fingerling production: Hatch and sell young catfish to other farmers.

• Feed formulation and sales: Produce and sell fish feed if you master local feed production.

• Training and consultation: Share your knowledge through workshops or social media.

As your farm grows, reinvest in better infrastructure, expand your pond capacity, or partner with fish retailers to scale. Keeping accurate records and maintaining healthy fish are the keys to consistent profits.

With good planning and marketing, catfish farming can become a stable, scalable, and sustainable business venture.
