Overview of Fish Farming in Kenya

Fish farming in Kenya contributes 1% to agricultural GDP and is growing. It focuses on tilapia, catfish, and ornamental fish, with tilapia being the most popular. The activity is mainly in water-rich regions like Kisumu, Kakamega, and the Rift Valley.

The government supports small farmers through initiatives like the Economic Stimulus Program. Now, Kenya produces over 24,000 metric tons of fish annually. This effort reduces pressure on natural water bodies and creates 250,000 jobs.

The demand for farmed fish is set to grow by 10% each year. This is due to increased health awareness, a rising population, and more people moving to cities. With the right management, fish farming can boost agriculture, create jobs, and enhance food security.

Fish Farming Regions in Kenya

Types of Fish Species Farmed in Kenya

Kenya’s fish farms focus on three main types of fish. Let’s look at each one.

1. Tilapia

Tilapia is the most popular fish for farming in Kenya. Here’s why:

• It grows fast and adapts well to different environments.
• The market demand is high.
• It’s easy to breed and care for.

Tilapia likes warm water between 20-30°C. Farmers often keep 2-3 fish per square meter of pond. They feed tilapia a mix of plant-based foods and special fish feeds.

A tilapia can grow from a tiny fish to market size in about 6-8 months. This quick growth makes it a favorite among farmers. Tilapia makes up nearly 75% of all farmed fish sold in Kenya.

2. Catfish

Catfish is the second most farmed fish in Kenya. Farmers like catfish because:

• It grows quickly.
• It can live in water that’s not very clean.
• Many people enjoy eating it.

To farm catfish, you need to:

1. Prepare the pond well.
2. Add the right number of fish.
3. Feed them correctly.
4. Harvest at the right time.

Catfish is popular for local meals. Some farmers also make special products from catfish to sell.

3. Ornamental Fish

Farming ornamental fish is a growing business in Kenya. These are pretty fish that people keep in tanks at home or in offices.

Popular types include:

• Goldfish
• Koi
• Guppies

Farming ornamental fish can be tricky. You need to:

• Keep the water very clean.
• Feed the fish special food.
• Handle the fish with great care.

But there’s good news. More people want to buy these fish. Some farmers even sell them to other countries.

Choosing the Right Fish

When starting a fish farm, pick the type that:

• Grows well in your area
• Has a good market nearby
• Fits your budget and skills

Each fish type requires unique care. So, learn about your chosen fish. This knowledge will ensure your farm’s success.

Setting Up a Fish Farm in Kenya

Step 1. Choosing the Right Site

Picking the right location is crucial. Here’s what to look for:

• Plenty of clean water: Your fish need it year-round.
• Good soil: If you’re digging ponds, the soil should hold water well.
• Flat or gently sloping land: This makes pond construction easier.
• Access to electricity: You’ll need it for pumps and equipment.
• Nearby markets: The closer, the fresher your fish will be when sold.

Pro tip: Visit local fish farms to get ideas. Experienced farmers can offer valuable advice about good locations.

Step 2. Pond Construction

You have three main options for fish farming:

• Earthen ponds: Cheapest option, but may leak.
• Lined ponds: Have a plastic liner to prevent leaks.
• Concrete ponds: Cost more, yet are durable and easy to clean.

For beginners, start with one or two small ponds. A good size is about 300 square meters each. This lets you learn without risking too much.

Costs vary, but expect to spend:

• Ksh 50,000 – 100,000 for a small earthen pond
• Ksh 100,000 – 200,000 for a lined pond
• Ksh 200,000 or more for a concrete pond

Remember to include:

• An inlet for adding fresh water
• An outlet for draining
• A sloping bottom for easy harvest

Step 3. Stocking Your Pond

Once your pond is ready, it’s time to add fish. Here’s how:

1. Buy fingerlings (young fish) from a trusted hatchery.
2. Transport them carefully in oxygenated bags.
3. Slowly acclimatize them to your pond water before releasing.

Stocking density depends on your pond type and fish species. For tilapia in earthen ponds, a good rule is 2-3 fish per square meter. So, a 300 square meter pond could hold 600-900 fingerlings.

Step 4. Water Management

Good water means healthy fish. Here’s what to do:

• Check water quality weekly: Test for pH, ammonia, and dissolved oxygen.
• Keep water flowing: Use pumps or gravity to add fresh water regularly.
• Watch the weather: Heavy rains or drought can affect your pond.

In dry areas, think about harvesting rainwater for your ponds. Meanwhile, some Kenyan farmers are using greenhouses over ponds. This method reduces evaporation and keeps water warm.

Step 5. Extra Tips for Success

1. Start small and expand gradually. Learn from each cycle.
2. Join a local fish farming association. Sharing knowledge is powerful.
3. Consider integrated farming. Some Kenyan farmers grow vegetables using nutrient-rich pond water, creating two income streams.
4. Keep good records. Track your costs, growth rates, and sales to improve over time.

Feeding and Nutrition in Fish Farming

Why Feeding Matters

Good feeding leads to:

• Faster fish growth
• Healthier fish that resist diseases
• Better-tasting fish that sell well

But be careful. Overfeeding wastes money and can pollute your pond.

Types of Fish Feed

Many successful farmers in Kenya use a mix of all three. You have three main options:

1. Commercial feeds: These are ready-made and balanced for fish needs. They’re convenient but can be expensive.
2. Homemade feeds: You can mix your own using local ingredients, like rice bran, wheat bran, and fishmeal. It’s cheaper but takes more work.
3. Natural pond food: Algae and small water creatures that grow in your pond. They’re free but not enough on their own for fast growth.

Feeding Different Fish

Different fish need different food:

• Tilapia: They eat both plants and small animals. They do well on a diet of 25-35% protein.
• Catfish: They’re meat-eaters. They need food with 35-40% protein.
• Ornamental fish: These need special diets, often with more color-enhancing ingredients.

Smart Feeding Tips

• Feed fish small amounts 2-3 times daily.
• Observe their eating. If food lasts 15-20 minutes, it’s too much.
• Adjust for temperature. Fish eat less in cold, more in warm.
• Use floating feed. It’s easier to monitor their intake.

Saving Money on Feed

Feed is pricey, but there are ways to save:

1. Make your own: Mix local ingredients to cut costs. Just make sure it’s balanced.
2. Grow natural pond food: Fertilize your pond to grow algae and small creatures fish can eat.
3. Buy in bulk: Team up with other farmers to get better prices.
4. Store feed properly: Keep it dry and cool to avoid waste.

Some clever Kenyan farmers are growing duckweed or water spinach near their ponds. These plants make great, cheap fish food.

Remember, good feeding is an investment. It might cost more up front, but it leads to bigger, healthier fish that bring better prices at the market.

Fish Health Management and Disease Control

Maintaining fish health is key for a successful farm. Now, let’s explore how to identify, prevent, and treat common fish health issues in Kenya.

Spotting Sick Fish

Healthy fish are active and eat well. Watch for these signs of illness:

• Unusual swimming patterns
• Not eating
• Spots or marks on the skin
• Bulging eyes
• Swollen bellies

If you see these signs, act fast. Sick fish can quickly infect others.

Common Fish Diseases in Kenya

• Bacterial Infections:
  • Aeromonas: Causes skin ulcers and bleeding.
  • Columnaris: Causes white patches on the skin or gills.
• Fungal Infections:
  • Saprolegnia: Looks like cotton-wool on the fish.
• Parasites:
  • Ich: Causes white spots on the skin.
  • Gyrodactylus: Tiny worms that irritate the fish’s skin.

Preventing Diseases

Prevention is better (and cheaper) than cure. Here’s how:

• Keep water clean: Change 10-15% of pond water weekly.
• Avoid overcrowding: Too many fish cause stress and disease.
• Feed properly: Good nutrition strengthens fish immunity.
• Quarantine new fish: Isolate newcomers for 2 weeks to check for diseases.
• Choose quality fingerlings: Buy from reliable hatcheries.

Some Kenyan farmers are using probiotics in their ponds. These good bacteria help keep the water clean and fish healthy.

Treating Sick Fish

If disease strikes:

1. Identify the problem: If you’re unsure, ask a local fish health expert.
2. Separate sick fish: Use a quarantine pond if possible.
3. Treat the water: Many treatments are added directly to the pond.
4. Follow instructions: Use the right amount of medicine for the right time.

Common treatments in Kenya include:

• Salt baths for parasites
• Antibiotics for bacterial infections (but use carefully)
• Potassium permanganate for fungal problems

Remember, some treatments can harm your fish if used wrong. When in doubt, ask an expert.

Working with Experts

Build a relationship with:

• Local fisheries officers
• Veterinarians who know about fish
• Experienced fish farmers in your area
