How do I treat White Gut Syndrome in shrimp without using antibiotics?

Apply Next Gut multi-strain probiotic (Citrobacter, Lactobacillus, Saccharomyces) mixed with feed at 15-20ml per kg twice daily for 5 days. Simultaneously broadcast Next Viro Nill water bio-conditioner at 1 Liter per acre to eliminate pathogenic Vibrio reservoirs.

What is the dosage of Next Converter for severe ammonia (NH3) spikes in pond water?

For active toxic ammonia spikes above 0.5 ppm TAN, apply 2.0 to 3.0 Liters of Next Converter per 1 Acre of pond surface (1 meter water depth) during morning aeration.

Are Next Farm Bio Sciences products approved by the Coastal Aquaculture Authority (CAA)?

Yes. All biological formulations produced by Next Farm Bio Sciences are approved by the Coastal Aquaculture Authority (CAA), certified under ISO 9001:2015, and guaranteed 100% free from banned antibiotics.

Can I order Next Farm products using Cash on Delivery (COD)?

No. To ensure optimal biological cold-chain handling and prevent transit delays for living bacterial formulations, all orders must be pre-paid securely online via Razorpay (UPI, GPay, PhonePe, Cards, NetBanking).

How quickly are orders dispatched to prawn farms in Andhra Pradesh?

Pre-paid orders confirmed before 2:00 PM IST are dispatched same-day from our New Autonagar, Vijayawada warehouse via dedicated express aquaculture freight, reaching coastal districts within 24-48 hours.

Recognizing the Symptoms

Visual indicators observed in check trays and water

1Persistent daily mortalities of 10 to 50 shrimp per pond from DOC 35 to 70.
2Dead shrimp appearing on pond dikes and in cast nets with no single obvious symptom.
3Faint white spots under carapace (White Spot Syndrome Virus warning sign).
4Shrimp swimming sluggishly along water surface and edges of aeration lines.
5Hepatopancreas pale with secondary bacterial infection.

Biological Root Causes

Pathogens, water chemistry & environmental triggers

1Low-grade viral complexes (IHHNV, HPV, or sub-acute WSSV) compromising immune resilience.
2Organic bottom sludge harboring viral particles and infected crab/carrier vectors.
3Sudden climatic fluctuations (heavy overcast skies, sudden drop in pond water temperature).
4Immune collapse due to poor water quality.

Field-Tested Application Schedule

5-Day Step-by-Step Treatment Protocol

Follow this exact day-by-day regimen to achieve full clinical recovery.

Day 1Stop all chemical applications; boost paddlewheel aeration to maximum capacity.

Feed Protocol:

Mix Next Gut @ 20 mL/kg feed with immune stimulants.

Water & Aeration Action:

Broadcast Next Viro Nill @ 2.0 Liters per Acre during morning aeration.

Day 2 - 3Daily mortality count in check trays begins dropping steeply.

Feed Protocol:

Continue Next Gut in all feed meals.

Water & Aeration Action:

Apply second dose of Next Viro Nill @ 1.0 L/Acre.

Day 5Normal growth and molting resume.

Feed Protocol:

Standard feeding resumed.

Water & Aeration Action:

Mortality ceases; shrimp resume vigorous benthic feed grazing.

Verified Field Case Study

Farmer Case: B. Srinivasa Rao (Repalle, Guntur District, Andhra Pradesh)

Pond Size & DOC: 3.0 Acre Vannamei Pond (DOC 48)

"Losing 30-40 shrimp daily to unexplained running mortality with neighboring ponds getting wiped out by WSSV. Applied Next Viro Nill @ 2L/Acre and Next Gut in feed. Within 72 hours, mortality stopped completely and crop successfully harvested at 32 count."

Frequently Asked Questions

Expert scientific guidance for prawn & shrimp cultivators

Next Viro Nill acts as an intense microbial biosecurity agent. It hydrolyzes viral-harboring organic bottom detritus, competitive-excludes vectors, and stimulates natural anti-microbial lipopeptides, drastically reducing viral transmission pressure in commercial ponds.
