1. REDUCED FEEDING STRATEGIES in TILAPIA

2. Intensification of Culture Results: Results: Increased production Increased production dependence on exogenous feeds dependence on exogenous feeds 60-70% of production cost is due to feed cost 60-70% of production cost is due to feed cost

3. 63%

4. Production methods emphasizing reduced feeding I. Delayed feeding onset II. Sub-satiation feeding III. Combined delayed feeding onset + sub-satiation feeding IV. Alternate day feeding strategy

5. I.Delayed Feeding Onset initial feeding 45 days and 75 days after stocking of tilapia fingerlings Fingerlings supported by pond plankton

6. Mean weight (g) of Nile tilapia in ponds at two feeding onsets

7. Nile tilapia growout performance with delayed feeding onsets
