Early EHP detection
PCR + microscopy diagnose before shrimp go off-feed

Shrimp off-feed, white feces,
FCR climbing?
EHP and Vibrio are destroying gut. Don't wait until shrimp die — prevent from day 15 to save the crop.
✓ Suppress EHP✓ Control Vibrio✓ Restore gut
White feces in shrimp is typically caused by gut microbiome imbalance combined with Vibrio and EHP (microsporidian). Treat with a 6-step protocol: water disinfection (Vibrio Clear), probiotic seeding (SoilMax), feed mixing FLASH 5g + CLEVER 5g/kg for 5 consecutive days. Prevention from day 15 of culture.
Quick Summary
Main Causes
- Water management
- Control harmful microbes
- Stabilize gut microbiome
Signs
- unstable pond environment enables pathogen growth
- Vibrio, EHP, protozoa attack gut and hepatopancreas
- dysbiosis leads to enteritis and white feces
Solutions
- Day 1 morning: Vibrio Clear 1kg/2,000m³
- Day 1 evening: Aqua Dine New 1kg/2,000-3,000m³
⚠ These are signs of EHP / Vibrio infection
01 Sudden off-feed, beach clinging
02 White feces around feeding trays
03 Empty/broken gut on inspection
04 Pale hepatopancreas, soft shell
05 FCR climbing from 1.4 to 1.8+
Why are white feces and EHP so persistent?
EHP can come from postlarvae, and Vibrio is always in the water
EHP lives in hepatopancreas — no specific cure
Vibrio thrives at high density, damaging gut
Gut microbiome out of balance
Keeps coming back if only symptoms are treated
⚠ Antibiotics-only → residue, next crop relapses

Treatment journey — Real protocolFrom detection to recovery —
From detection to recovery —
the 14-day protocol
01
Detect early
Scope gut, check Vibrio, PCR for EHP — don't wait until shrimp go off-feed. Start prevention from day 15.
02
Double disinfection: morning + evening
Morning: Vibrio Clear 1kg/2,000m³ — kill harmful bacteria. Evening: Aqua Dine New 1kg/2,000–3,000m³ — concentrated organic iodine, safe and shock-free. In parallel, mix FLASH 5g + CLEVER 5g/kg feed for 4–5 consecutive days.
03
Shrimp eat again in 3–5 days
Shrimp resume eating, feces turn brown, gut fills back. Lower the dose when stable — don't stop abruptly.
04
Full recovery in 14 days
Even gut, pink hepatopancreas, FCR back to 1.4. Maintain FLASH 3g + CLEVER 3g/kg through end of crop to prevent relapse.
How to use FLASH + CLEVER for white feces
- ➤ Double disinfection AM/PM Morning: Vibrio Clear 1kg/2,000m³. Evening: Aqua Dine New 1kg/2,000–3,000m³
- ➤ Prevent from day 15 FLASH 3g + CLEVER 3g/kg, 2 feeds/day
- ➤ When signs appear Increase to FLASH 5g + CLEVER 5g/kg for 4–5 days
- ➤ Late season Maintain FLASH 3g + CLEVER 3g/kg until harvest
When to combine FLASH+CLEVER with other solutions?
FLASH+CLEVER focuses on parasites and gut bacteria. If water is bad or hepatopancreas is weak — combine more solutions.
FAQ
Frequently Asked Questions
Can white feces spread from one pond to another?
Yes. EHP and Vibrio causing white feces spread through water, equipment, and infected postlarvae. Disinfect equipment between ponds, PCR-test postlarvae before stocking.
Can EHP be cured?
EHP (Enterocytozoon hepatopenaei) is a microsporidian with no complete cure yet. The solution is FLASH to suppress EHP + CLEVER to control Vibrio + boost immunity so shrimp can coexist with the pathogen.
What culture day does white feces typically appear?
Typically appears from day 30-50, when shrimp start eating heavily and pond organics increase. Ponds with EHP history may see it earlier from day 20. Prevent with FLASH + CLEVER from day 15.
What is the treatment cost for white feces per 1,000m³?
The cost is quite high compared to prevention. The success rate is at a certain level. Prevention from the start is the best
Can shrimp with white feces recover their appetite?
Yes. After 3-5 days of proper treatment, the shrimp will start eating again. Consider harvesting the shrimp if they are hight level infected with EHP.
What should be checked before treating white feces?
Check: (1) Total Vibrio and green Vibrio in water/liver, (2) PCR test for EHP, (3) microscope shrimp gut, (4) measure NH3/NO2/pH. Results help choose the correct protocol.
What's the difference between FLASH and CLEVER?
FLASH contains active compounds that suppress EHP and microsporidians, focusing on parasites. CLEVER contains antimicrobial enzyme extract, focusing on Vibrio suppression. Combine 5g+5g/kg feed for comprehensive effect.
