How to Treat White Gill Disease in Red Tilapia
Understanding the Cause of White Gill Disease in Red Tilapia
The disease is caused by the filamentous bacteria Myxococcus piscicolas (from the family Myxococcaceae, order Myxococcales, class Deltaproteobacteria, phylum Proteobacteria). These bacteria thrive in pH levels of 6.5–7.5, warm temperatures of 25–35°C, and in spring and autumn seasons, especially in ponds with high organic waste pollution.
Symptoms of White Gill Disease
Gill filaments become necrotic, eroded, torn, and decayed, often accompanied by heavy mud deposits.
Hemorrhaging and erosion are visible on the surface of the operculum bones, causing deformities.
Diseased fish may exhibit abnormal behavior such as swimming sluggishly near the surface, isolating themselves from the school, and reducing or ceasing to feed.
Steps to Treat White Gill Disease
Steps to Prepare and Manage the Pond for Treating White Gill Disease in Red Tilapia
Properly prepare the pond by thoroughly dredging and cleaning the pond bottom. Ideally, use lined ponds to minimize disease outbreaks.
Design an efficient siphon drainage system. During the farming process, manage the environment effectively to limit organic pollution by controlling feed quantities.
Replace pond water regularly to maintain cleanliness.
Frequently clean cage walls to ensure proper water flow rates.
Periodically treat the water with Virkon® A at a dosage of 0.7 kg per 1,000 m³ of pond water, or place it in fabric bags around the cages to eliminate harmful bacteria.
Continuously mix 5 g of Aqua C® Fish and 3 g of Grow Fish per 1 kg of feed, administering it for 7–10 days each month to enhance the fish's resistance during temperature fluctuations.
If the disease is detected early, immediately treat the fish by mixing 5–10 g of BayMet® and 5 g of Aqua C® Fish per 1 kg of feed (or 1 kg of BayMet® + 1 kg of Aqua C® Fish for 3–5 tons of fish) and feeding them for 7–10 consecutive days.
Bathe the fish in BayMet® at a concentration of 2–5 g/m³ of water.
By following these steps, farmers can effectively treat and manage white gill disease in red tilapia. Wishing you a successful and productive farming season!
