Causes:

1. Poisoning: ammonia nitrogen, sub-salt, sulfide, etc. Shirmps turn yellow, black or white

2. Bacterial infection: shrimps turn red, swelling and atrophy

3. Metabolic problems or stress caused by high protein feed: heavy burden on hepatopancreas , turn red and swelling

Process:

1. Dark brown: normal, clear outline of white fatty membrane and hepatopancreas
2. Turn into light red or dark red: hepatopancreas enlargement, little change in ADI (acceptable daily intake)
3. Red to white: mid-stage, feed intake become slow
4. Completely white: late-stage, feed intake stop and with mortality  

Solution:

1.  Poisoning: Splash Aqua Culture （one of Clostridium butyricum’ s product）with vitamin C for anti-stress and detoxification. And splash bacillus products or Super EM （one of Clostridium butyricum’ s product）to reduce ammonia, nitrogen and sub-salt.
2.  Bacterial infection: Use disinfectant and antibacterial drugs, alternate use of Aqua Combo （one of Clostridium butyricum’ s product）for adjuvant treatment and quick recovery.
3.  Metabolic problems or stress: Use Aqua Combo（one of Clostridium butyricum’ s product） along with polysaccharides, multi-vitamins, bile acids, etc., to protect the liver, increase immunity and anti-stress.

Prevention:

Seedling phase - Use Lactobacillus, Clostridium butyricum mix with feed

Liver development phase - Use Aqua Combo（one of Clostridium butyricum’ s product）, bile acid, etc

Follow-up regular health care: Use Aqua Combo every 5-7 days for 3 consecutive days
