Practical Methods of Using Garlic to Prevent and Treat Fish Diseases

1. Treating enteritis: For every 100 kg of fish, use 0.5 kg of garlic bulbs, plus 0.3 kg of table salt, mix with feed and feed to the fish for 3-6 consecutive days.

2. Treating hemorrhagic disease: For every 10,000 fish, use 0.25 kg of garlic bulbs, 4 kg of alligator weed (fresh), and 0.2 kg of table salt, grind together with soybean cake and feed, twice a day for 4 consecutive days.

3. Treating dropsy (scale-standing disease): Add 0.25 kg of mashed garlic bulbs to every 50 kg of water, and soaking the diseased fish several times gives a good therapeutic effect.

4. Treating gill rot and enteritis: For every 50 kg of fish, use 500 g each of garlic, rhubarb and table salt, mix with bait and feed to the fish for 6 consecutive days.

5. Microcapsules made from garlic extract or synthetically produced allicin can be stored for a long time; they have broad-spectrum antibacterial action, do not pollute water sources, and do not affect hygiene inspections for export.

6. The dosage of allicin powder for preventing and treating gill rot, enteritis, hemorrhagic disease and fungal disease is: 10-15 g per 100 kg of fish per day, fed for 3-5 consecutive days, or 1-2 g of allicin powder added to every 50 kg of feed, fed for three consecutive days. Besides being added to bait to prevent and treat diseases, garlic also acts as an attractant, increasing the fish's appetite.
