Feeding Schedule for Fast-Growing Catfish
Optimized Nutrition for Maximum Growth and Profitability
Proper feeding management is crucial for achieving optimal growth rates in catfish farming. This guide provides detailed feeding schedules tailored to each growth phase.
Growth Phase Feeding Schedule
Phase 1: Day-Old to 2 Weeks (Fingerlings)
Feeding Frequency: 4-5 times daily
Feed Type: High-protein (35-45%) floating starter feed
Particle Size: 0.3-0.5 mm crumbles
Daily Ration: 15-20% of body weight
Key Considerations:
- Feed lightly but frequently to support rapid metabolism
- Use high-quality, easily digestible feed
- Monitor water quality closely as high feeding rates increase waste
- Ensure feed is fresh and properly stored
Phase 2: 2-6 Weeks (Post-Fingerlings)
Feeding Frequency: 3 times daily (reduce to 2 if water quality drops)
Feed Type: Floating feed (28-35% protein)
Particle Size: 1.5-2.0 mm pellets
Daily Ration: 8-12% of body weight
Key Considerations:
- Continue using floating feed to monitor consumption
- Adjust feeding based on water temperature and quality
- Begin training fish to specific feeding times and locations
- Monitor growth rates weekly
Phase 3: 6 Weeks to Harvest (Grow-Out)
Feeding Frequency: 2 times daily (morning & evening)
Feed Type: 28-32% protein floating feed
Particle Size: 3.0-6.0 mm pellets
Daily Ration: 3-5% of body weight
Key Considerations:
- Adjust feeding based on fish size and appetite
- Monitor Feed Conversion Ratio (FCR) closely
- Reduce feeding during extreme temperatures
- Prepare for harvest when growth rates plateau
| Growth Phase | Weight Range | Daily Feeding Rate (% of body weight) | Protein Requirement | Expected FCR |
|---|---|---|---|---|
| Fingerlings | 0.1 - 5g | 15-20% | 40-45% | 1.0-1.3 |
| Post-Fingerlings | 5 - 50g | 8-12% | 35-40% | 1.2-1.5 |
| Juveniles | 50 - 200g | 5-8% | 32-35% | 1.4-1.7 |
| Grow-Out | 200 - 1000g | 3-5% | 28-32% | 1.6-2.0 |
Essential Feeding Tips for Success
✓ Optimal Feeding Times
Feed during cooler hours: 7-9 AM and 4-6 PM when water temperatures are moderate and fish metabolism is optimal.
Avoid feeding during the hottest part of the day (12-2 PM) when dissolved oxygen levels are lowest.
✓ Monitor Feeding Response
Observe fish behavior during feeding:
- Active, aggressive feeding indicates good appetite
- Slow consumption suggests overfeeding or health issues
- Adjust quantities based on consumption within 15-20 minutes
✓ Prevent Water Pollution
Remove leftover feed to maintain water quality:
- Uneaten feed decomposes, releasing ammonia
- Regular water quality testing is essential
- Implement proper waste management systems
✓ Seasonal Adjustments
Adapt feeding to seasonal changes:
- Reduce feeding by 30-50% during cold seasons
- Increase feeding during optimal temperature ranges (26-30°C)
- Monitor water temperature daily
The Growth Formula
This simple formula represents the three pillars of successful catfish farming. Neglecting any one of these components will significantly impact your growth rates and profitability.
Key Success Factors for Maximum Growth
Consistent Schedule
Maintain regular feeding times to establish routines and maximize feed utilization efficiency.
Water Quality Management
Monitor and maintain optimal parameters: dissolved oxygen >5 mg/L, ammonia <0.05 mg/L, pH 6.5-8.5.
Quality Nutrition
Use feeds with balanced protein, energy, vitamins, and minerals tailored to each growth stage.
Stocking Density
Maintain appropriate densities: 15-25 fish/m³ for optimal growth without overcrowding stress.
Expected Growth Performance
With proper feeding management, African catfish can reach harvest size (700g-1kg) in 5-6 months with Feed Conversion Ratios of 1.5-1.8 under optimal conditions.
