Protocol QT-06
Internal parasites and undigested faeces
Deworm on a schedule rather than waiting for symptoms. It is the cheapest prevention in the whole crop.
Step 0 · Identify
What you see at the pond
Undigested faeces persisting after deworming usually means feed or cold, not bacteria. Check the feed store before reaching for antibiotics.
- Undigested, loose faeces
- Poor appetite, slow growth, uneven size
- Parasites visible in the gut on necropsy

Withdrawal
4 weeks
AQUA PRAZI needs 4 weeks before harvest, counted from the last dose on day 5.
No improvement in 3–5 days
Check the feed store — damp or rancid feed is the leading cause. Cold weather also cuts digestion. Neither is solved with antibiotics.
Note
Deworm on a schedule, not on symptoms.
