Achatina achatina is a large land snail native to West Africa and one of the most commercially valuable snail species you can raise in Nigeria. It is commonly called the Giant Ghana Snail or Tiger Snail. If you are looking to start snail farming in Nigeria, understanding what Achatina achatina is, how it grows, and how to care for it properly is the single most important thing you can do before spending a kobo.
At Zendric, we have spent over 12 years training Nigerian farmers on Achatina achatina farming. Our founder, Peter Uzodimma, trained at Odeda Farm Institute in Ogun State and has worked directly with hundreds of farmers across Southern and Northern Nigeria. In this guide, we share everything we know from real farm experience, not theory.
1. What is Achatina Achatina Snail?
Achatina achatina is a species of large, air-breathing land snail. It belongs to the family Achatinidae and is found naturally across the rainforest regions of West Africa, including Nigeria, Ghana, Ivory Coast, and Benin Republic.
The name “Achatina” comes from the Greek word for agate, referring to the banded pattern on the snail’s shell. The word “achatina” is repeated in the species name to make it a distinct species from its close relatives like Achatina fulica.
In Nigeria, most people call it “Congo Meat” or “Nwa Eke” in Igbo. It is widely eaten across the South, Southwest, and increasingly in the North. The snail is prized for its large size, rich protein content, and its role in traditional cooking.
According to the Food and Agriculture Organization (FAO), snail meat contains up to 16% crude protein, very low fat, and high iron content, making it one of the healthiest animal proteins available in Nigeria.
2. Why Achatina Achatina is Popular in Nigeria
Nigeria’s demand for snail meat is huge. But the supply from the wild has dropped badly because of deforestation and over-harvesting. This has created a wide gap between what people want to buy and what is available in the market.
Here is why Nigerian farmers are choosing Achatina achatina specifically:
- It is the largest snail species commonly farmed in Nigeria
- It grows to impressive weights of 300g to over 500g per snail
- It commands the highest price per kilogram in hotels, restaurants, and export markets
- It survives well in Nigeria’s tropical climate without expensive temperature control
- It can be raised in backyards, small pens, or large commercial farms
At Zendric, we track market prices across Lagos, Abuja, and Port Harcourt regularly. Mature Achatina achatina consistently sells for between N3,500 and N4,500 per kilogram, which is higher than any other farmed snail species in Nigeria. You can use our Snail Farm Profit Calculator to estimate what your own farm could earn.
3. Physical Features You Must Know
Knowing how to identify Achatina achatina accurately is critical. Many traders in Nigerian markets sell the wrong species. If you buy the wrong snail, you will face wrong management, slow growth, and poor market returns.
Shell Appearance
The Achatina achatina shell is elongated and cone-shaped. It has a sharp, pointed apex at the top. The shell displays a distinctive tiger stripe pattern with bands of brown, cream, and sometimes reddish colors.
An adult shell typically grows between 18 and 25 centimeters in length. The shell is thick and heavier than other species.
Body Features
The body (or foot) of Achatina achatina is long and muscular. The skin color is usually dark grey to brownish, with visible ridges along the body. The tentacles (horns) are long and well-defined.
When you handle a mature Achatina achatina, it feels strong and moves slowly with deliberate, steady movements. Juveniles are more active and quicker.
Size and Weight at Different Stages
| Growth Stage | Age | Average Weight | Shell Length |
|---|---|---|---|
| Hatchling | 0 to 4 weeks | 0.5 to 2g | 1 to 2cm |
| Juvenile | 1 to 6 months | 5 to 80g | 3 to 10cm |
| Sub-adult | 6 to 12 months | 80 to 200g | 10 to 17cm |
| Market-Ready | 12 to 18 months | 200 to 350g | 17 to 22cm |
| Fully Mature | 18 months and above | 350 to 500g+ | 22 to 25cm |
4. Achatina Achatina vs Other Species: Key Differences
Many farmers mix up Achatina achatina with Archachatina marginata (another popular Nigerian species) or Achatina fulica (the smallest of the three). These are different animals with different needs.
Getting confused about which species you have will lead to wrong feeding, wrong housing, and wrong market targeting.
Here is a clear comparison of the three most commonly farmed species in Nigeria:
| Feature | Achatina Achatina | Archachatina Marginata | Achatina Fulica |
|---|---|---|---|
| Common Name | Tiger Snail / Giant Ghana Snail | Giant West African Snail | East African Land Snail |
| Mature Weight | 300 to 500g+ | 150 to 250g | 50 to 150g |
| Shell Length | 18 to 25cm | 12 to 18cm | 7 to 12cm |
| Time to Market | 12 to 18 months | 8 to 12 months | 6 to 10 months |
| Eggs Per Clutch | 6 to 12 | 8 to 15 | 100 to 400 |
| Market Price (per kg) | N3,500 to N4,500 | N2,800 to N3,800 | N1,500 to N2,500 |
| Best For | Premium and export markets | Beginners, quick cash flow | Fast breeding, volume sales |
We cover this comparison in much more detail in our post: Achatina achatina vs Archachatina marginata: The Complete Guide.
5. How to Set Up a Farm for Achatina Achatina in Nigeria
Setting up correctly from the start will save you a lot of money and heartache. Here is what you need to know.
Choosing a Location
Achatina achatina prefers cool, shaded, and humid environments. Avoid locations with direct afternoon sun.
Good locations include:
- Under mango, pawpaw, or banana trees
- Inside a building with good ventilation
- Shaded backyard areas
Avoid waterlogged areas. Flooding kills snails quickly and causes disease. The ideal temperature range for Achatina achatina is 20 to 30 degrees Celsius.
Types of Pens
You have three main options for housing Achatina achatina snails in Nigeria:
Trench or Hutch Boxes are the most common. These are simple wooden or block enclosures built on the ground. They are inexpensive and easy to manage for small farms.
Concrete Pens are more durable and easier to clean. They are better for large commercial operations where hygiene is a priority.
Free-Range Pens use wire mesh fencing around a natural area. This is the most natural method but harder to monitor and protect from predators.
At Zendric, we recommend beginners start with simple wooden hutch boxes and upgrade to concrete pens as their farm grows.
Space Requirements
Achatina achatina needs more space than smaller species because of its size.
- Allow at least 0.1 square meters per adult snail
- Overcrowding leads to slow growth, disease, and fighting
- For 100 adult snails, you need at least 10 square meters of floor space
Soil Requirements
Soil is very important for Achatina achatina. These snails live partially in the soil, especially when laying eggs. The soil must:
- Be loamy and well-draining, not clay or sandy
- Have a pH between 6.5 and 7.5
- Contain calcium-rich material (add crushed snail shells or limestone)
- Be kept moist but never waterlogged
Change or refresh the topsoil in your pen every 2 to 3 months to prevent disease buildup.
6. How to Feed Achatina Achatina Snails
Feeding is where many farmers lose money. Achatina achatina has specific nutritional needs, and meeting them properly is the difference between slow snails and fast-growing, profitable ones.
What Achatina Achatina Eats
These snails are herbivores. They eat plant matter. In nature, they feed on decaying leaves, fruits, bark, and soil minerals.
On a farm, you should feed them:
Leaves and Vegetables: Pawpaw leaves, plantain leaves, cassava leaves, cocoyam leaves, waterleaf, and fluted pumpkin (ugwu) leaves.
Fruits: Overripe pawpaw, watermelon, banana, cucumber, and tomatoes. Avoid citrus fruits as they are too acidic.
Calcium Sources: Crushed snail shells, bone meal, oyster shell powder, or food-grade chalk. Calcium is critical for shell formation. Without enough calcium, Achatina achatina shells become thin and brittle.
Commercial Feeds: Poultry pellets and fish meal can be used as protein supplements. Some farmers also use soaked soybean meal.
How Much Do They Eat?
A healthy adult Achatina achatina eats between 40 and 60 grams of feed per day.
Feed your snails in the evening. Achatina achatina is nocturnal, meaning it is most active at night. Feeding at dusk encourages maximum eating.
Remove uneaten food the next morning to avoid rotting, which attracts pests and causes disease.
Foods to Avoid
Never feed Achatina achatina the following:
- Salt or salty food (even tiny amounts can kill snails)
- Onions and garlic
- Citrus fruits (oranges, lemon, lime)
- Spicy peppers
- Any processed human food
7. How to Care for Achatina Achatina Through Every Season in Nigeria
Nigeria has two main seasons: the rainy season and the dry season (Harmattan). Each season brings different challenges for Achatina achatina farming.
Caring for Achatina Achatina During the Rainy Season (April to October)
The rainy season is the most natural and comfortable time for Achatina achatina. Growth is fastest during this period. However, you must watch for:
Flooding: Ensure your pen has proper drainage. Standing water kills snails.
Overbreeding: Snails are most active sexually during rains. If you are not ready for hatchlings, manage your population carefully.
Fungal infections: High humidity can cause shell fungus. Ensure good ventilation in the pen.
Caring for Achatina Achatina During Harmattan (November to March)
Harmattan is the most dangerous season for Achatina achatina. The dry, dusty winds cause snails to aestivate (go into a protective sleep) and can kill dehydrated snails.
Key care steps during Harmattan:
- Water your soil lightly every day to maintain moisture
- Cover the top of your pen with shade netting or banana leaves
- Mist the pen walls with water twice daily
- Check on snails daily and remove any that look inactive or sealed shut for too long
We have a full guide on moisture management during the dry season at: How to Maintain Ideal Soil Moisture During Nigeria’s Dry Season.
8. Breeding and Reproduction of Achatina Achatina
Understanding how Achatina achatina reproduces will help you plan your production cycles and avoid overcrowding.
Key Reproductive Facts
Achatina achatina is hermaphroditic, meaning each snail has both male and female reproductive organs. However, they still need another snail to mate with. They cannot fertilize themselves.
| Reproductive Feature | Detail |
|---|---|
| Age of First Mating | 8 to 12 months |
| Eggs Per Clutch | 6 to 12 eggs |
| Number of Clutches Per Year | 4 to 6 |
| Incubation Period | 21 to 28 days |
| Hatchling Survival Rate | 70 to 85% (with proper care) |
The Egg-Laying Process
When Achatina achatina is ready to lay eggs, it burrows 5 to 10 centimeters into the soil and deposits the eggs in a small chamber. The eggs are white, oval-shaped, and about the size of a small marble.
Do not disturb the soil unnecessarily during the breeding season. Accidental disturbance can cause the snail to abandon the eggs.
Caring for Hatchlings
Hatchlings are tiny (about 1cm) and very delicate. Move them to a separate hatchling pen immediately to protect them from adult snails, which can accidentally crush them.
Feed hatchlings soft foods: tender leaves, soft vegetables, and finely crushed calcium powder. At Zendric, we recommend using plastic baskets for the first 4 to 8 weeks of a hatchling’s life. See our guide: How to Use Plastic Baskets for Raising Snail Hatchlings in Nigeria.
9. Common Health Problems and How to Handle Them
Healthy snails grow fast and fetch good prices. Sick snails drag your entire farm down. Here are the most common health problems with Achatina achatina in Nigeria and how to deal with them.
Shell Problems
Thin or cracked shells are the most common problem in Nigerian Achatina achatina farms. The cause is almost always calcium deficiency. Fix this by adding bone meal or crushed snail shells to their diet daily.
Shell fungus appears as white or green patches on the shell. It happens when humidity is too high without enough ventilation. Improve airflow in the pen and isolate affected snails.
Body Infections
Bacterial infections show up as soft, discolored, or foul-smelling flesh. Isolate infected snails immediately. Remove and dispose of any dead snails quickly to prevent the infection from spreading.
Internal parasites are less common but can occur when snails eat contaminated soil or food. Use clean, sourced soil and wash all vegetables before feeding.
Predators and Pests
Common threats to Achatina achatina in Nigerian farms include:
- Soldier ants (they attack and kill snails quickly)
- Lizards and monitor lizards
- Rats and mice
- Frogs (they compete for food and moisture)
Use wire mesh with holes no larger than 5mm to keep predators out. Check the mesh regularly for gaps.
Prevention is Better Than Treatment
The best way to keep Achatina achatina healthy is through consistent prevention:
- Clean the pen at least once a week
- Remove uneaten food every morning
- Change bedding soil every 2 to 3 months
- Maintain proper humidity and ventilation
- Quarantine any new snails for 2 weeks before adding them to your main pen
10. When and How to Sell Your Achatina Achatina Snails
Selling at the right time and in the right way determines how much profit you actually make.
Best Time to Sell
Achatina achatina prices rise significantly during certain periods:
- December and January (Christmas, New Year, and New Year celebrations)
- Easter period (March/April)
- During Ramadan, when demand shifts but non-Muslim demand stays high
- Dry season months, when wild snails are scarce
We have a detailed guide on timing your sales here: When to Sell Snails for the Highest Price.
Where to Sell
Hotels and Restaurants are the best buyers for Achatina achatina because they pay a premium for large, well-presented snails. Target 3-star and above hotels in Lagos, Abuja, and Port Harcourt.
Markets and Traders offer steady volume sales. Lagos markets like Mile 12 and Owode Onirin, as well as Ketu market, are among the largest snail trading hubs in Nigeria.
Direct to Consumer via WhatsApp, Instagram, and online platforms is growing fast. Younger buyers in cities now order snails directly from farmers.
Export Markets in Europe (especially Belgium, France, and the UK) pay the highest prices but require food safety certifications and proper packaging.
How to Package for Sale
Clean your snails properly before sale. Do not use salt to clean them. Rinse with plain water only. Package in ventilated containers, mesh bags, or wooden crates. Label your packaging with your farm name and contact for brand recognition.
11. Profitability: What You Can Realistically Earn from Achatina Achatina Farming
Let us look at real numbers. These are estimates based on farms managed by Zendric students across Ogun, Lagos, Rivers, and Enugu states.
Small Farm Example (100 Snails)
| Item | Cost / Revenue |
|---|---|
| 100 Breeder Snails | N25,000 |
| Pen Construction | N15,000 |
| Feed for 12 months | N18,000 |
| Miscellaneous | N5,000 |
| Total Investment | N63,000 |
| Survivors (85%): 85 snails at 300g average = 25.5kg | |
| Revenue at N4,000 per kg | N102,000 |
| Net Profit (Year 1) | N39,000 |
Note: Year 2 profit is significantly higher as you do not repeat pen construction costs and your breeders start producing offspring.
Scaling Up
Once you understand the process with 100 snails, scaling to 500 or 1,000 snails reduces your cost per snail while increasing your total income. Many Zendric students who started with N50,000 are now earning N200,000 to N400,000 per production cycle.

5 Frequently Asked Questions About Achatina Achatina Snail in Nigeria
FAQ 1: What is the difference between Achatina achatina and Achatina fulica?
Achatina achatina is much larger, growing up to 500 grams or more when fully mature. It has a distinctive tiger stripe pattern on its shell. Achatina fulica is smaller, usually reaching only 50 to 150 grams. Fulica grows faster and produces far more eggs (up to 400 per clutch), but it sells for a much lower price per kilogram. For premium markets and export in Nigeria, Achatina achatina is the better choice. For high-volume, low-cost production, Achatina fulica may suit some farmers.
FAQ 2: How long does it take Achatina achatina to grow to market size in Nigeria?
Under proper care, Achatina achatina reaches market-ready size (200 grams and above) in 12 to 15 months. Full maturity at 300 to 500 grams takes 15 to 18 months. Growth speed depends on feeding quality, calcium availability, pen conditions, and the weather. Snails kept in cool, humid pens with consistent feeding grow faster than those in dry or overcrowded pens. Do not rush sales. Larger snails fetch significantly better prices.
FAQ 3: How many eggs does Achatina achatina lay per year?
A healthy adult Achatina achatina typically lays between 6 and 12 eggs per clutch and completes 4 to 6 clutches per year. This means one breeding snail can produce 30 to 60 eggs annually. With a hatching success rate of around 75 to 85%, you can expect 25 to 50 live hatchlings per breeder per year. This is much fewer than Achatina fulica or Archachatina marginata, but the larger final size more than compensates in revenue terms.
FAQ 4: Can I farm Achatina achatina in Northern Nigeria?
Yes, you can farm Achatina achatina in Northern Nigeria, but it requires more active management. The drier climate in states like Kano, Kaduna, and Abuja means you must manage humidity carefully, especially during Harmattan. Use covered pens with shade netting, water your soil daily, and mist the pen walls regularly. Some successful Zendric students operate profitable farms in Abuja and Kano. The key is not to copy farm setups designed for the humid South without adapting them to your local conditions.
FAQ 5: Where can I buy genuine Achatina achatina snails in Nigeria to start my farm?
Always buy from verified, experienced snail farmers rather than market traders. Market traders often mix species or sell unhealthy stock. Look for farmers who can confirm the species by showing you the tiger stripe shell pattern and mature size. Agricultural fairs, farmer cooperatives, and trained snail farming instructors are your safest sources. At Zendric, we connect buyers with trusted snail sources. Visit our Shop page or Contact Us to ask about verified breeders in your area.
Final Thoughts
Achatina achatina snail farming in Nigeria is a real, proven business. It is not a get-rich-quick scheme, but with the right knowledge and consistent effort, it delivers steady, growing income with relatively low starting capital.
At Zendric, we have seen farmers start with N25,000 and build farms earning hundreds of thousands of naira per year. The difference between those who succeed and those who fail is almost always knowledge and proper management, not just money.
