How Can We Help?

Measures feed efficiency. Lower FCR = better conversion. Ideal shrimp FCR: 1.2–1.8.

Example: 1500 kg feed ÷ 1000 kg gain = 1.5 FCR

Calculate water volume for stocking density and chemical dosing. 1 m³ = 1000 liters.

Example: 50m × 20m × 1.5m = 1,500 m³ = 1,500,000 liters

Optimal density varies by species. Vannamei: 60–100/m², Tilapia: 3–5/m².

Example: 100,000 PL ÷ 5,000 m² = 20 pieces/m²

Saturation depends on temperature and salinity. Target: >70% for most species.

Example: 6.5 mg/L ÷ 8.2 mg/L × 100 = 79.3%

Calculate volume needed for partial water changes. Typical: 10–30% daily.

Example: 1,500 m³ × 30% = 450 m³

Estimate revenue based on current market prices and expected harvest weight.

Example: 2,125 kg × ₹850/kg = ₹18,06,250

Net profitability after all expenses. Target: >25% for sustainable operations.

Example: (₹18L − ₹12L) ÷ ₹18L × 100 = 33.6%

Estimate total harvestable biomass from stocking data.

Example: 100,000 × 0.85 × 25g ÷ 1000 = 2,125 kg

Calculate aerator horsepower needed based on stocking and species oxygen demand.

Example: 2,000 kg × 2 mg/L/hr ÷ 1.5 kg O₂/HP = 2.7 HP

Temperature differential risk assessment. |ΔT| > 5°C indicates stress risk.

Example: Air 35°C − Water 28°C = ΔT 7°C (High Risk)

Calculate the feed cost component of production cost.

Example: (1500 kg × ₹45/kg) ÷ 1000 kg = ₹67.5/kg biomass

Track mortality and survival performance across crop cycles.

Example: 85,000 ÷ 100,000 × 100 = 85% survival
