Shrimp suddenly stop eating, scattered mortality rising fast in 2-3 days?
Vibrio parahaemolyticus is the most damaging pathogen in shrimp farming. One day delay can lose the entire pond.
Vibrio parahaemolyticus is the most damaging pathogen in shrimp farming — causing EMS/AHPND acute hepatopancreas necrosis. When shrimp suddenly stop eating with rapidly increasing scattered mortality → disinfect immediately with VIRO TRAP, seed SOILMAX New after 24h, feed CLEVER + FLASH to suppress Vibrio. One day delay can lose the entire pond.
Quick Summary
Main Causes
- V. parahaemolyticus
- Total Vibrio density exceeds threshold
- Dirty pond bottom, organic sludge
Signs
- causes EMS/AHPND, acute hepatopancreas necrosis
- microbial imbalance in pond
- ideal environment for Vibrio
Solutions
- Disinfect water with VIRO TRAP 1kg/1,000m³ or POWER GLUTA 1L/1,500m³
- After 24h
- Feed CLEVER + FLASH

Disinfect water with VIRO TRAP 1kg/1,000m³ or POWER GLUTA 1L/1,500m³
After 24h — apply SOILMAX New to restore beneficial microbes
Feed CLEVER + FLASH — suppress Vibrio from inside the gut
Boost immunity with AQUAMOS + BETAGLUCAN GRO
Maintain probiotics every 3-5 days — control Vibrio density
Expected Results
Acute symptoms reduce, shrimp stabilize
Clear improvement, shrimp resume eating
Full recovery, maintain with regular probiotics

AQUAMOSFrequently Asked Questions
What Vibrio CFU level is dangerous?
Total Vibrio above 10⁴ CFU/mL in pond water and green Vibrio (V. parahaemolyticus) above 10² CFU/mL is the warning level. Disinfect immediately with VIRO TRAP or POWER GLUTA when exceeded.
Is shrimp glowing at night caused by Vibrio?
Yes. Luminous shrimp (luminous vibriosis) is caused by Vibrio harveyi. Disinfect water immediately with VIRO TRAP + feed CLEVER to suppress gut Vibrio. Check green Vibrio on TCBS agar.
How long after disinfection before applying probiotics?
Wait at least 24 hours after disinfecting with VIRO TRAP/POWER GLUTA before applying SOILMAX New. If applied too early, the disinfectant will kill the beneficial probiotics just added.
Is there a vaccine for EMS/AHPND prevention?
No commercial vaccine for EMS/AHPND exists yet. Best prevention: maintain beneficial microbes with regular SOILMAX New, boost immunity with AQUAMOS + BETAGLUCAN GRO, control Vibrio with CLEVER.
Does heavy rain increase Vibrio levels?
Yes. Heavy rain drops pH, reduces alkalinity, stresses shrimp → lower resistance → Vibrio surges. After rain: (1) raise alkalinity with GROWMIN, (2) boost resistance with AQUAMOS, (3) monitor Vibrio on TCBS agar.
