1. The High Stakes of FCR Economics in Commercial Aquaculture
With commercial pelleted aquafeed costing ₹90 to ₹115 per kilogram, Feed Conversion Ratio (FCR) is the single largest determinant of farm net profitability. A farm harvesting 20 Metric Tons at an FCR of 1.60 consumes 32,000 kg of feed (₹32 Lakhs).
Reducing FCR to 1.28 on the same crop consumes only 25,600 kg of feed—saving ₹6.4 Lakhs in cash while drastically reducing nitrogenous waste excretion, preventing ammonia spikes, and preserving pond bottoms.
2. Daily Feeding Rate (% Body Weight) Across Growth Stages
Feed quantity must be calculated from standing biomass and Average Body Weight (ABW), adjusted for water temperature:
| Shrimp ABW (Grams) | Estimated Count (pcs/kg) | Daily Feed Rate (% Biomass) | Meals Per Day | Check Tray Allocation (% of Meal) |
|---|---|---|---|---|
| 1.0 – 3.0 g | 330 – 1,000 | 6.5 – 5.5% | 3 Meals | 0.5% in 2 Trays |
| 3.1 – 8.0 g | 125 – 320 | 5.0 – 4.0% | 4 Meals | 0.8% in 4 Trays |
| 8.1 – 15.0 g | 67 – 120 | 3.8 – 3.2% | 4 Meals | 1.0% in 4 Trays |
| 15.1 – 22.0 g | 45 – 65 | 3.0 – 2.6% | 4 Meals | 1.2% in 4 Trays |
| 22.1 – 32.0 g | 31 – 45 | 2.5 – 2.1% | 4 Meals | 1.5% in 4 Trays |
| >32.0 g (Jumbo) | <31 | 2.0 – 1.8% | 3 Meals | 1.5% in 4 Trays |
3. Check Tray Architecture & Inspection Timing
Install 4 standard check trays (80 cm × 80 cm square with 5 cm raised sides) per 1-acre pond, positioned 2 to 3 meters off pond dikes in representative water depths away from aerator mud currents.
Place exactly 1.0% to 1.2% of the calculated meal ration onto the check trays. Inspect trays at precisely 90 minutes (for shrimp <15g) or 120 minutes (for shrimp >15g):
• Trays completely clean: Increase next meal by 5%.
• 5–10 pellets remaining: Maintain current feeding ration.
• >20 pellets remaining: Cut next meal by 25%.
• Trays untouched: Cancel next meal entirely; immediately investigate DO and ammonia levels.
4. Critical Environmental & Molting Corrections
• Heavy Rain: Cut feed by 50% immediately. Runoff drops salinity and water temperature, temporarily halting digestion.
• Dissolved Oxygen <4.0 ppm: Cut feed by 50%. Below 3.0 ppm, DO is insufficient for aerobic digestive metabolism.
• Peak Molting Days: Cut feed by 20% on the day preceding new moon/full moon ecdysis, as soft shrimp do not feed actively.
5. Maximizing Nutrient Assimilation with Next Food Pro
Shrimp possess a short digestive tract with transit times of just 60 to 90 minutes. Top-dressing commercial feed with Next Food Pro delivers concentrated protease, amylase, lipase, and phytase enzymes that pre-digest complex feed proteins into readily absorbable peptide chains, improving nutrient retention and reducing fecal nitrogen.
Next Food Pro (Enzyme & Digestive Booster)
Manufactured under sterile conditions in New Autonagar, Vijayawada, Andhra Pradesh. Directly calibrated against the clinical protocol outlined above.
Mix Next Food Pro with feed and binder thoroughly, then shade-dry for 20 to 30 minutes in a cool, ventilated area before broadcasting. Never dry in direct sunlight, which destroys delicate digestive enzymes.
