Treatment methods for goldfish hemorrhagic disease
Causes: The factors causing hemorrhagic disease in goldfish are relatively complex; it is generally triggered by viral, bacterial, and environmental factors:
1. Viruses, bacteria (generally thought to be Bacillus monocytogenes), and parasites attack the fish body, causing damage to the whole body or local areas.
2. Water quality Whether using tap water, lake water, or well water to raise fish, it must be left to stand or exposed to sunlight for 2-3 days before use. If used directly without treatment, it will at best cause congestion of the fins and scales, and at worst kill the goldfish.
[Symptoms] Congestion, bleeding, ulcers, and scale loss on the fins throughout the body (especially at the base) and between the scales or in local areas; in severe cases, there is bleeding in the mouth, eyes, and internal organs. Sick fish float listlessly or sink to the bottom and swim lazily. In mild cases, appetite decreases; in severe cases, they refuse food, the body color becomes dull, they become emaciated, secretions increase, and they die from concurrent bacterial saprolegniasis and septicemia.
[Season of onset] It can occur year-round, especially from June to October.
[Prevention and treatment methods]
(1) In addition to paying attention to the prevention of the above causative factors, check for parasites at the bleeding sites and remove them if present. At the same time, apply mercurochrome to the affected areas, then place the fish in a small basin, rinse briefly, and return it to the original pond (tank) to rest. Do this once a day until healed.
(2) Place the sick fish in a 10-20 mg/L solution of nitrofurazone or furazolidone, or in 2%-3% saline, and soak for 10-15 minutes, then rinse and put it into the pond (tank). Do this every other day.
(3) For severe cases, add 1,000,000 units of kanamycin or 80,000-160,000 units of gentamicin to 10 kg of water. Give the sick fish a water bath and let it rest for 2-3 hours, or at most half a day, then transfer it to new water for rearing. Do this once a day; generally 2-3 times is enough for recovery.
