1. Clinical Overview & Background
Pangasius (Basa / P. hypophthalmus) — Culture Guide is a fundamental operational phase in successful aquaculture pond management.
Adhering to scientifically validated standard operating procedures ensures maximum survival rates, optimal Feed Conversion Ratios (FCR), and protects farm investments against bio-risks.
4. Step-by-Step Action Protocol
Stocking density: 25–50 fish/m³ in cages; 60,000–100,000 fish/ha in ponds
Tolerates low DO (> 2 mg/L) but grows best at > 4 mg/L
Feed: 25–28% protein floating pellets; FCR 1.5–1.8
Culture period: 6–8 months for 1–1.5 kg market size
Highly susceptible to Columnaris and EUS during monsoon
Water depth: 2–3 m preferred
MPEDA export certification required for international markets
5. Water Parameters & Dosage Benchmarks
| Parameter / Item | Recommended Value | Operational Importance |
|---|---|---|
| Recommended Soil pH | 6.5 – 7.5 | Optimal soil microbial activity |
| Agricultural Lime (CaCO₃) | 200 kg / acre | Neutralizes soil acidity |
| Plowing Depth | 15 – 20 cm | Exposes toxic black bottom sludge to oxygen |
7. Frequently Asked Questions
Q: Why is this protocol necessary for high-density farming?
High stocking densities (> 50 PL/m²) create high biological oxygen demand and waste. Standard protocols maintain environmental stability.
Q: How often should this management process be repeated?
This should be executed prior to every stocking cycle during dry pond preparation.
