1. Clinical Overview & Background
Preserving shell hardness, color, and cold chain freshness during harvest directly dictates the final price per kg paid by seafood exporters and traders.
The Pre-Harvest Moult Check outlines pre-harvest sampling checks, ice slurry ratios, and buyer negotiation best practices.
4. Step-by-Step Action Protocol
Check feeding trays 3 days before planned harvest.
If more than 5% of the shrimp are soft-shelled (recently moulted), delay the harvest by 2-3 days.
Apply Calcium/Magnesium supplements to accelerate shell hardening if needed.
5. Water Parameters & Dosage Benchmarks
| Parameter / Item | Recommended Value | Operational Importance |
|---|---|---|
| Ice to Shrimp Ratio | 1 : 1 (1 kg ice per 1 kg shrimp) | Rapid chill killing at 0°C |
| Max Allowable Soft Shell % | < 3% | Avoids buyer price deduction |
7. Frequently Asked Questions
Q: What should I do if my shrimp moult right before harvest?
Postpone harvest by 48–72 hours and apply Calcium Carbonate and Magnesium Chloride at 50 kg/acre to accelerate shell hardening.
