Nutritional Management

Precision Extruded Pellet Feeding Schedule

Optimized crude protein and feeding frequencies across life stages to minimize feed wastage and maximize growth velocity.

Life StageDurationCrude Protein (CP %)Feed Type & Pellet SizeFeeding Rate (% Biomass)Feeding Frequency
Post-Larvae Acclimatization (Nursery)Day 1 to Day 3038% – 40% CPCrumble micro feed #0 to #2Check feed check trays (4 trays per acre)4 times / day
Grow-out & Carapace ThickeningDay 31 to Day 10534% – 36% CP1.6 mm to 2.2 mm sinking shrimp pellets2.5% to 3.5% adjusted via check tray clearance4 times / day
Feeding Tray Inspection: Check feed trays 90 minutes after feeding. If feed remains unconsumed, reduce subsequent feedings by 20% to prevent water fouling and lethal ammonia spikes.

Health Prophylaxis

Critical Disease Diagnosis & Biosecurity Treatments

Immediate identification and legal aquatic medication protocols for pathogens affecting Brackishwater Pacific White Shrimp (Vannamei).

White Spot Syndrome Virus (WSSV)

सफेद धब्बा रोग (WSSV वायरस)
Causative Pathogen:Whispovirus (WSSV)
Symptoms:White calcium spots on carapace, lethargic swimming near bunds, 100% mortality within 3 to 5 days.
Prescribed Treatment / Control:Zero chemical cure exists. Use only CAA-certified SPF (Specific Pathogen Free) broodstock seeds with PCR negative certificates.

Early Mortality Syndrome / AHPND

अर्ली मॉर्टेलिटी सिंड्रोम (AHPND)
Causative Pathogen:Vibrio parahaemolyticus carrying Photorhabdus toxin genes
Symptoms:Pale, atrophied hepatopancreas, empty gut, sudden mortality within first 35 days.
Prescribed Treatment / Control:Regular application of Bacillus and Rhodobacter photosynthetic soil probiotics to outcompete luminous Vibrio bacteria.
SOP Guidelines

5 Golden Aquaculture Rules for Brackishwater Pacific White Shrimp (Vannamei)

1

Line pond bottoms with 500-micron virgin HDPE geomembrane sheets to eliminate soil seepage and organic black sludge buildup.

2

Deploy minimum 8 to 10 HP aeration per acre (paddle wheel + spiral jet aerators) to maintain dissolved oxygen above 5.0 ppm.

3

Check feed consumption using 4 check trays (80cm x 80cm) per pond; adjust feeding quantity if feed is not cleared within 90 minutes.

4

Supplement ionic mineral ratios: Maintain Calcium, Magnesium, and Potassium in a 1:3:1 ratio for flawless shrimp molting.

FAQ

Frequently Asked Questions: Brackishwater Pacific White Shrimp (Vannamei) Farming

Yes! Inland saline groundwater in states like Haryana (Sirsa, Hisar), Punjab (Muktsar, Fazilka), and Rajasthan has natural salinity of 5 to 20 ppt. When fortified with potassium and magnesium minerals, inland farmers produce export-quality Vannamei shrimp yielding ₹10+ Lakhs net profit per acre.
