Treatment of fish bleeding

[cause] the causes of goldfish hemorrhagic disease are complicated, which are generally caused by viral, bacterial and environmental factors:

1. Viruses, bacteria (generally believed to be caused by Monomonas) and parasites invade the fish, causing systemic or local damage to the fish.

2. The relationship between water quality and tap water does not work. It is still fish culture in lake water or well water. It can only be used after standing or exposure for 3 days. If it is used directly without treatment, the fin scales will be congested if it is light, and the goldfish will die if it is heavy.

[symptoms] systemic fins (more severe at the base), interscale or local hyperemia, bleeding, ulcers, scales falling off; severe bleeding in the mouth, eyes and internal organs, sick fish floating or lazy at the bottom, light loss of appetite, refusing to eat, dim body color, emaciation, increased secretions, bacterial water mildew and septicemia.

[onset season] can occur all the year round, especially from June to October.

[prevention and control methods]

(1) in addition to paying attention to the prevention of the above pathogenic factors, check for parasites in the area of bleeding, and if so, catch them. At the same time, wipe the affected area with red mercury, then rinse it in a small basin and put it back to the original pool (tank) to rest, once a day, until cured.

(2) soak the diseased fish in 10 murine 20 mg / L furacillin or dysentery solution or 2%-3% salt water for 10-15 minutes, then wash them into the pool (tank) once every other day.

(3) in serious cases, 1 million units of kanamycin or 80, 000 to 160000 units of gentamicin were added to 10 kg of water, and sick fish were reclaimed in water bath for 3 hours, and most of them were reared in new water half a day later. Once a day, usually 2 mi 3 times will be cured.
