REDUCED FEEDING STRATEGIES in TILAPIA

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

63%

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

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