Tilapia farming guide — Kenya
Tilapia farming is aquaculture: the fish grow in ponds or tanks of clean water, not in soil, so what you need is water and space rather than fertile land. It is a strong option for farmers near a reliable water source, and for youth or groups pooling a shared pond. Tilapia is the most popular fish for Kenyan beginners.
What you need
- System
- Earthen or lined ponds, or tanks, filled with clean fresh water at least 1 m deep
- Stocking
- About 3 fingerlings per square metre in a pond; use monosex (all-male) fingerlings for even, fast growth
- Feed
- Floating pellets at 3 to 5% of body weight per day (28 to 32% protein), split into two feeds
- Water
- 25 to 30°C, clean and well-oxygenated; refresh or aerate to keep the quality high
- Cycle
- 6 to 8 months to reach a 300 to 500 g market size
Economics
Buyers: local markets, restaurants, hotels, and fish traders. Catfish often sells live, which fetches a premium.

Frequently asked questions about tilapia farming in Kenya
Do you need land or soil to farm tilapia in Kenya?
No. Tilapia is grown in ponds or tanks of water, not in soil, so you need water and space rather than fertile land. That opens fish farming to people without good cropland, as long as they have a reliable water source.
What do you need to start tilapia farming?
A pond or tank, clean water, quality fingerlings, and pelleted feed. About 3 fingerlings per square metre in a pond; use monosex (all-male) fingerlings for even, fast growth.
How long does tilapia take to reach market size?
6 to 8 months to reach a 300 to 500 g market size. Floating pellets at 3 to 5% of body weight per day (28 to 32% protein), split into two feeds.
How much can you earn from tilapia in Kenya?
Tilapia sells for around KES 450/kg. A cycle gives about 250 to 400 kg from a 300 m² pond per cycle in a semi-intensive system.
What is the biggest problem in tilapia farming?
The main risk is overstocking and poor water quality, which stunt the fish, plus uncontrolled breeding — use monosex fingerlings or add a few catfish to eat the fry.
