How to treat freshwater ornamental fish with Chinese loach disease?
In fact, most crustaceans are beneficial to ornamental fish, but there are also some crustaceans that parasitize ornamental fish, which will cause mechanical damage to the fish body tissue, thus providing good conditions for pathogens to enter their bodies.
Among crustaceans, there are three main types of gilltails, isopods, and copepods that parasitize ornamental fish. Although there are not many species of crustaceans parasitic on ornamental fish, parasitic intensity can also cause death. Today kittens will come to discuss Chinese loach disease with you.
Chinese loach belongs to the copepod, mainly in the freshwater ornamental fish, when the ornamental fish mildly infected with the Chinese loach when mildly there are no obvious symptoms, but in severe cases will cause inflammation at the end of the parotid filament, swelling and swelling into a mallet pale and bloodless, swelling and swelling of the gill congestion or bleeding spots on the gills. Sick fish will have a loss of appetite, difficulty breathing, swimming alone, when the sick fish gills are opened, the naked eye can observe that the end of the gills is attached to the maggot-like white worms, so it is also called "maggot disease". And the Chinese gill will also hook through the gill tissue of the diseased fish, causing many wounds in addition to being able to seize nutrients, but also for other microbial invasion to provide convenient conditions With the aggravation of the disease, the sick fish will be restless, breathing difficulties, appetite loss until it is abandoned, and swim wildly on the surface of the water, the upper leaves of the tail fin are often exposed to the water, so it is also called "tail disease", and finally it will die of suffocation or emaciation.
Precautions:
(1) It can be disinfected with quicklime water clearing the pond, which can kill the Chinese loach larvae, insect eggs and small trash fish with insects in the water.
(2) Strengthen feeding management, as far as possible do not choose the water source with Chinese loach larvae as the breeding water, and often replace the new water, so as to ensure a good environment and enhance the resistance of the fish body.
(3) When fish fingerlings are stocked, medicinal baths can be carried out with drugs. 6 to 7 grams of copper sulfate and 2 to 3 grams of ferrous sulfate per cubic body of water, medicinal bath for 10 to 30 minutes.
(4) In the season of illness, the use of copper sulfate and ferrous sulfate mixture in the fish pond hanging bag, can also be effective prevention and control.
Treatment:
(1) The ratio of copper sulfate and ferrous sulfate compound is 5:2 for whole pool sprinkling, 0.7 grams per cubic meter of water, which has a good therapeutic effect.
(2) The use of 2.5% dichlorvos powder is sprinkled throughout the pool, which is the final concentration of the pool water drug 2.0 grams per cubic meter of water, and the same effect is also available when the water temperature is above 24 ° C. However, it is necessary to pay attention to the concentration of the anti-insect medicinal bath to prevent poisoning.
