Tilapia is known as the “aquatic chicken.” It has become a global staple fish and protein source because it grows fast and breeds easily in captivity. An easy fish to culture, it is tolerant to a wide range of salinity and temperature levels. Moreover, farming tilapia requires minimal inputs.
How to breed and culture TILAPIA?
Hatchery in netcages
- Install 3 x 10 x 0.75 m fine-meshed netcages in ponds or 3 x 10 x 1.5 m fine-meshed netcages in lakes
- Stock four (3 females and 1 male) or five (4 females and 1 male) tilapia breeders (3-4 month old, minimum 100 g) per square meter
- Feed breeders at 3% of total biomass with tilapia feeds containing 40% protein
- Check for the presence of fry three weeks after stocking the breeders
- Collect fry and transfer to nursery netcages
- Place breeders in separate holding facilities and continue feeding them high-protein tilapia feeds for the next breeding cycle
Nursery in netcages
- Stock 800-1,000 fry/m2 in netcages of appropriate mesh size
- Feed fry with supplemental feeds to avoid or minimize cannibalism
- Sort fry after two weeks
- Re-stock fingerlings according to size in separate netcages
- Transfer fingerlings to grow-out enclosures when total length is 37 mm (size 17) to 46 mm (size 14)
Grow-out in ponds
- Prepare the pond by sun drying the pond bottom and applying lime to stabilize soil and water pH. Lime is unnecessary when soil pH is above 7.5 and the alkalinity of the pond water is above 50 mg/liter of CaCO3
- Stock 1-2 fingerlings/m2 for extensive systems, 3-4 fingerlings/m2 for semi-intensive systems, and 5-10 fingerlings/m2 for intensive systems
- Feed fingerlings with tilapia feeds daily at 2-3% of the total fish biomass in semi-intensive systems and at 3-5% of the total fish biomass in intensive systems
- Intensive systems require good water management (water change as needed) apart from additional provisions like paddlewheel aerators
- Harvest fish when they reach the market size of 150-300 g (4-6 months)
