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.

Why do chemical sanitizers fail to control Vibrio?

Chemical sanitizers (bleaching powder, BKC, glutaraldehyde) kill all beneficial microbes in the pond. Because Vibrio grows three times faster than other bacteria, it repopulates within 48 hours with higher virulence. Probiotics like Next Vibriosis use competitive exclusion to permanently occupy biological niches.

Recognizing the Symptoms

Visual indicators observed in check trays and water

1Shrimp developing reddish appendages, red body pigmentation, and red uropods/telson.
2Luminescent glowing in pond water or dead shrimp at night (Vibrio harveyi).
3Green Vibrio colonies exceeding 1 x 10^3 CFU/ml on TCBS agar plate tests.
4Melanized black necrotic lesions on exoskeleton, tail rot, and antennal breakage.
5Lethargy and mass mortality during molting cycles.

Biological Root Causes

Pathogens, water chemistry & environmental triggers

1High organic benthic load creating breeding grounds for Vibrio parahaemolyticus.
2Sudden drop in salinity or temperature shock weakening shrimp immune defenses.
3Use of harsh chemical disinfectants that wipe out good bacteria and trigger virulent Vibrio rebound.
4Contaminated post-larvae (PL) carrying sub-clinical bacterial infections.

Field-Tested Application Schedule

5-Day Step-by-Step Treatment Protocol

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

Day 1Discontinue chemical sanitizers to allow competitive probiotic colonization.

Feed Protocol:

Feed Next Vibriosis @ 15 mL/kg feed coated with binder in all feed trays.

Water & Aeration Action:

Broadcast Next Vibriosis @ 1.5 L/Acre mixed with 20L water across pond dikes.

Day 2Red discoloration on appendages begins fading to natural translucent hue.

Feed Protocol:

Continue 15 mL/kg feed in morning and evening rations.

Water & Aeration Action:

Maintain vigorous aeration to support probiotic aerobic metabolism.

Day 3 - 4Shrimp antenna regeneration and active feeding resumption.

Feed Protocol:

Reduce feed dose to 10 mL/kg feed.

Water & Aeration Action:

Retest water sample on TCBS plate; green Vibrio drops by 90%.

Verified Field Case Study

Farmer Case: G. Subba Reddy (Kavali, Nellore, Andhra Pradesh)

Pond Size & DOC: 4.0 Acre Brackish Water Pond

"TCBS lab test showed green Vibrio at 4,200 CFU/ml with shrimp developing red tail and dying in corners. Broadcasted Next Vibriosis and coated feed for 4 days. Green Vibrio plummeted below 200 CFU/ml with zero further mortality."

Frequently Asked Questions

Expert scientific guidance for prawn & shrimp cultivators

Next Vibriosis is the industry-standard biological antagonist. It produces bacteriocins and organic acids that specifically eliminate pathogenic green Vibrio (V. parahaemolyticus and V. alginolyticus) without harming beneficial microalgae.
