FLASH — Biological support for EHP, white feces & hepatopancreas recovery

Beta-glucan + Butyric acid — controls Quorum Sensing, reduces gut microbiota imbalance, supports shrimp recovery under EHP and white feces pressure.

FLASH is Than Vuong's flagship biological product, designed to support shrimp during disease pressure — especially EHP (Enterocytozoon hepatopenaei) and white feces, two conditions with no targeted antibiotic.

1. Mechanism of action — 3 fronts

With Beta-glucan ≥ 20,000 mg and Butyric acid ≥ 1,800 mg, FLASH works on three parallel fronts:

  • 🔬 Quorum Sensing control — disrupts harmful bacteria signalling without harming beneficial microbes.
  • 🛡️ Natural immunity boost — helps shrimp withstand pathogen pressure.
  • 💚 Hepatopancreas recovery & gut stability — reduces stress, improves digestion.

2. Dosage

Mix with clean water, blend into feed, coat with ATOMIC, dry 20 min:

  • EHP prevention from day 15: 3 g/kg feed, 2 meals/day, throughout the cycle.
  • EHP-history ponds: 5 g/kg feed, 2 meals/day, from day 1 post-stocking.
  • WFS with EHP suspicion: 5 g/kg + CLEVER 5 g/kg, 4 meals/day, 5 – 7 days.
  • Pair with AQUAMOS 3 g/kg for beta-glucan immune support.

3. When is FLASH essential

  • Ponds with EHP-positive PCR (pre-stocking or mid-cycle test).
  • Abnormal FCR rise (> 1.4) while shrimp still eat strongly — silent EHP marker.
  • Recurring WFS — usually from EHP weakening the gut foundation.
  • Regions with EHP history — full-cycle prevention is safe practice.
📋 Official dosage from product label

Verbatim from the FLASH (500 g) label — synced with the product page to avoid drift.

Ingredients: Bột nấm men (Yeast extract), Acid butyric.
Directions & dosage:

Mix the product with sufficient clean water, thoroughly mix into feed, coat with ATOMIC or a suitable coating product, and let dry for 20 minutes before feeding shrimp. During farming: Feed from the start at 3 g/kg feed, 3 meals/day. During and after disease treatment: 5 g/kg feed, 4 meals/day. Note: Dosage may vary depending on shrimp health and actual farming conditions. Seal tightly, zip the bag immediately after use if the product is not fully consumed.

Label benefits:
  • Optimal control of Quorum Sensing without affecting beneficial bacteria.
  • Strongly inhibit the growth of harmful bacteria.
  • Reduce intestinal dysbiosis.
  • Reduce stress in farmed animals, significantly improve hepatopancreas.
