Protocol QT-04No antibiotic
White liver, white gill from repeated antibiotics
Farmers often mistake this for a fresh bacterial infection and feed more antibiotic, deepening the loop.
Step 0 · Identify
What you see at the pond
Not a new infection. Ask the pond's history first: how many antibiotic courses, and how long each.
- Pale white liver and gills
- Prolonged poor appetite, slow growth
- History: several antibiotic courses, or one long course
Handling
Day by day
Environment first, medicine after. The chart below includes the withdrawal period.
- 1Stop feeding, heavy water changeDay 1–2
Do not add any antibiotic at this stage.
- 2Cut the pathogen loadDay 3–4FYTOBLOOM PLUS1 L / 1,500 m³
Without FYTOBLOOM PLUS, use AQUA DINE New 1 bottle/2,000–2,500 m³.
- 3Iron and B12, liver recoveryDay 3–7Fe+B12 + HERB GUARD100 ml/5 t fish + 1 L/1,000 kg feed
Check with Than Vuong technical staff before choosing an iron + B12 supplement.
- 4Cut the pathogen load againDay 11FYTOBLOOM PLUS1 L / 1,500 m³
- 5Deworm if gill flukes are foundDay 8–12AQUA PRAZI100 g / 20–30 kg feed, 3–5 days
Only this step creates a withdrawal period — 4 weeks.
Withdrawal
None
No antibiotic is used, so no withdrawal period — unless the AQUA PRAZI step is used, which is 4 weeks.
No improvement in 3–5 days
The liver recovers over weeks, not days. If the fish are not feeding again after five days, repeat the protocol — do NOT switch to antibiotics, which would deepen the very cause.
Note
Heavy gill fluke burden is also a cause. Check the gills before blaming the drugs.
