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.

Does zeolite powder work better than ammonia reducer probiotic?

Zeolite only physically binds ammonia temporarily and gets saturated within 12 hours, releasing ammonia back when agitated. Biological converters like Next Converter permanently transform ammonia molecules into harmless nitrogen compounds through active bacterial nitrification.

What is the dosage of Next Converter per acre?

For active toxic spikes above 1.0 ppm TAN, apply 2.0 to 3.0 Liters per Acre. For regular weekly maintenance from DOC 30 onwards, apply 500 mL to 1.0 Liter per Acre every 7 to 10 days.

Recognizing the Symptoms

Visual indicators observed in check trays and water

1Shrimp swimming erratically near pond surface or water aerators at dawn.
2Gills turning brown, black, or congested with mucus from nitrite burns.
3Water color changing to dark cloudy brownish-green with sharp pungent odor.
4Test kit showing Total Ammonia Nitrogen (TAN) > 1.0 ppm and Nitrite (NO2) > 0.5 ppm.
5Sudden mortality spikes during molting cycles.

Biological Root Causes

Pathogens, water chemistry & environmental triggers

1Over-feeding and unconsumed high-protein pellet feed decomposing on the pond bottom.
2Heavy accumulation of shrimp fecal matter in low-circulation anaerobic dead zones.
3Sudden phytoplankton algae crash releasing massive organic decomposition load.
4High pond water pH (> 8.3) shifting harmless ammonium (NH4+) into lethal free unionized ammonia gas (NH3).

Field-Tested Application Schedule

5-Day Step-by-Step Treatment Protocol

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

Hour 0 - 6Turn on all paddlewheel aerators to drive dissolved oxygen above 5.0 ppm.

Feed Protocol:

Immediately slash feeding by 40% to stop raw protein nitrogen input.

Water & Aeration Action:

Apply Next Converter @ 2.0 to 3.0 Liters per Acre during morning aeration.

Hour 24Shrimp resume normal benthic grazing behavior.

Feed Protocol:

Resume light feeding with vitamin C / gut support.

Water & Aeration Action:

Retest TAN and NO2. Ammonia drops by 60% to 80% as Nitrosomonas colonize.

Hour 48 - 72Nitrite converts completely into non-toxic nitrate (NO3).

Feed Protocol:

Gradually scale feed back to normal schedule based on check tray clearance.

Water & Aeration Action:

Apply 1.0 L/Acre Next Pro to maintain stable water column microbiome.

Verified Field Case Study

Farmer Case: M. Venkat Rao (Narsapur, West Godavari, Andhra Pradesh)

Pond Size & DOC: 2.5 Acre High-Density Vannamei (DOC 65)

"Pond water TAN ammonia spiked to 3.5 ppm after heavy rain with shrimp gathering near aerators. Broadcasted 5 Liters of Next Converter across 2.5 acres. Within 24 hours, TAN dropped to 0.4 ppm and shrimp mortality ceased immediately."

Frequently Asked Questions

Expert scientific guidance for prawn & shrimp cultivators

Next Converter contains pre-activated autotrophic nitrifying consortia (Nitrosomonas and Nitrobacter @ 4 Billion CFU/ml) that start converting unionized toxic ammonia into nitrite and non-toxic nitrate within 6 to 12 hours of broadcast, achieving safe TAN levels within 24 to 36 hours.
