CLEVER 200g — the Vibrio and biofilm slayer in shrimp ponds

Yeast-derived antagonistic concentrate (min 20% protein) — disrupts Quorum Sensing, breaks down biofilm, and tames white feces & EMS without harming beneficial gut microbes.

CLEVER is Than Vuong's flagship for controlling Early Mortality Syndrome (EMS) and White Feces Syndrome (WFS) in whiteleg shrimp. Unlike conventional antibiotics, CLEVER targets the bacterial signaling system (Quorum Sensing), breaks Vibrio biofilms, and dampens virulence — all while preserving the shrimp's beneficial gut microbiome.

1. Why CLEVER is the new-generation Vibrio weapon

Vibrio doesn't attack shrimp on its own — it needs to “talk” via Quorum Sensing (QS) to form biofilms and release toxins. CLEVER's bioactive peptides and amino acids cut that QS signaling, leaving pathogens unable to colonize and effectively disarmed.

This mechanism is fundamentally different from antibiotics: no resistance pressure, no damage to Bacillus / Lactobacillus, and safe for season-long use as proactive prevention.

2. Dosage — prevention and treatment

Mix CLEVER with clean water, blend into feed, coat with ATOMIC, and let dry 20 minutes before feeding:

  • Routine prevention: 2 – 3 g/kg feed, 2 meals/day — throughout the cycle.
  • Treatment for white feces / loose feces / weak hepatopancreas: 5 – 7 g/kg feed, 4 meals/day.
  • Combine with FLASH 5 g/kg to control EHP, white feces, and hepatopancreatic disease together.
  • May be broadcast directly into pond water to disrupt pathogen QS in the water column.

3. Field results

After 5 – 7 days at the right dose, farmers typically observe: longer faecal strands, full dark-brown gut, strong feeding response, and a clear drop in total Vibrio / green Vibrio counts on TCBS plates. CLEVER is especially effective at 30 – 60 day stage — peak organic load and Vibrio pressure.

4. When to combine CLEVER with other products

CLEVER is the backbone of the white feces and TPD protocols, but pairs best with:

  • + FLASH (5 g + 5 g/kg): control EHP and microsporidians alongside Vibrio.
  • + HEPA PRO / HERB GUARD: rehab the hepatopancreas when liver is pale or atrophied.
  • + PRO SUR: restore gut mucosa after the acute phase.
  • + Vibrio Clear (water disinfection) + SoilMax (probiotic seeding): complete the 6-step white feces protocol.

5. Storage & notes

Store in a dry, cool place, away from direct sunlight, below 30°C. Reseal the bag immediately after use. Dosage may vary with shrimp health and pond conditions — call Than Vuong technicians on 0867 957 568 for a tailored protocol.

📋 Official dosage from product label

Verbatim from the CLEVER (200 g) label — synced with the product page to avoid drift.

Ingredients: Protein (extracted from yeast).
Directions & dosage:

Mix the product with a sufficient amount of clean water, mix thoroughly into the feed, coat with ATOMIC or a suitable coating product, and let dry for 20 minutes before feeding to shrimp. Routine use: 2 – 3 g/kg feed, 2 times/day. For periods requiring intestinal support: 5 – 7 g/kg feed, 4 times/day. Can be fed in combination with FLASH to enhance effectiveness. Note: Seal tightly, zip the bag immediately after use if the product is not fully consumed.

Label benefits:
  • Support to enhance nutrition.
  • Supports balancing the shrimp's intestinal microbiota.
  • Provide amino acids and bio-peptides.
  • Supports hepatopancreatic-intestinal health stability.
  • Enhance the resistance and natural immunity of shrimp.
