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.

Can I mix Next Sludge with zeolite or dry sand?

Yes. Mixing Next Sludge with clean dry sand helps the heavy granules carry beneficial bacteria directly to the benthic mud layer instead of dispersing in the top water layer.

Recognizing the Symptoms

Visual indicators observed in check trays and water

1Black rotten mud and foul-smelling sulfur odor when pulling check tray anchors.
2Shrimp tails and swimmerets covered in black stains or rusty deposits.
3Bubbles of hydrogen sulfide (H2S) gas rising to pond surface on sunny afternoons.
4Shrimp avoiding bottom center feeding zones and congregating along pond edges.
5Slow molting and poor bottom feed conversion.

Biological Root Causes

Pathogens, water chemistry & environmental triggers

1Continuous accumulation of unconsumed shrimp feed pellets over 40+ DOC.
2High shrimp stocking density generating hundreds of kilograms of fecal waste.
3Inadequate aeration leaving pond floor central dead zones anaerobic (oxygen < 1 ppm).
4Accumulation of dead microalgae sediment after plankton crashes.

Field-Tested Application Schedule

5-Day Step-by-Step Treatment Protocol

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

Day 1Broadcast directly over bottom feeding areas and center sludge zones.

Feed Protocol:

Normal feeding with strict feeding tray monitoring.

Water & Aeration Action:

Apply Next Sludge @ 2.0 Liters per Acre mixed with sand or pond water.

Day 3Foul sulfur odor diminishes as Bacillus enzymes digest organic lignin & proteins.

Feed Protocol:

Normal feeding.

Water & Aeration Action:

Inspect bottom soil core; black soil thickness noticeably shrinks.

Day 7Pond floor returns to healthy light brown sandy texture.

Feed Protocol:

Normal feeding.

Water & Aeration Action:

Apply maintenance dose of Next Sludge @ 1.0 L/Acre.

Verified Field Case Study

Farmer Case: T. Rajesh (Machilipatnam, Krishna District, Andhra Pradesh)

Pond Size & DOC: 3.0 Acre Pond (DOC 70)

"Bottom soil core showed 6 inches of foul black mud with H2S gas bubbles causing shrimp feed refusal. Applied Next Sludge @ 2 Liters/Acre. Within 5 days, sludge depth reduced by over 60%, black discoloration cleared, and feed trays cleared completely."

Frequently Asked Questions

Expert scientific guidance for prawn & shrimp cultivators

Next Sludge utilizes a multi-strain consortium of facultative anaerobic Bacillus, Bacillus megaterium, and fungal cellulase/protease enzymes that penetrate deep into bottom mud pores, enzymatically breaking complex proteins and lipids into harmless carbon dioxide and water.
