Harvesting tilapia in 3 months is doable, but you need to follow an intensive growth plan with the right conditions. Here's a step-by-step guide:

1. Choose Fast-Growing Tilapia Strain

· Use Nile tilapia (Oreochromis niloticus) or a hybrid strain known for fast growth.

· Fingerlings should be at least 5–10g when stocked.

2. Stocking Density

· Intensive system: 3–5 fish per square foot in tanks or cages.

· Extensive system (ponds): 1–2 fish per square meter.

3. Water Quality

· Temperature: 27–30°C (81–86°F) for optimal growth.

· pH: 6.5–8.5

· Dissolved oxygen: ≥5 mg/L

· Use aeration if needed.

4. Feeding

· Feed high-protein pellets (30–35%) for the first month, then shift to 25–28%.

· Feed 2–3 times daily.

· Feed rate: 5–7% of body weight/day (reduce as fish grow).

5. Monitoring Growth

· Sample fish every 2 weeks to adjust feed and estimate harvest date.

· Aim for 400–600g harvest weight within 90 days.

6. Harvesting

· Use seine nets or drain the pond/tank.

· Sort and grade the fish; remove any underdeveloped ones.
