Chrysalis disease: A large number of Chrysalis (insects that are difficult to observe with the naked eye) attach to gills, destroy gills, affect respiration, and suffocate fry. Prevention and control methods: ① 0.5 grams of copper sulfate and 0.2 grams of ferrous sulfate per cubic meter of water (0.7 grams of copper sulfate can also be used alone) dissolved in warm water at 40 - 50℃ and then splashed in the whole pool. (2) Sprinkle 0.5g dissolved water containing 50% diethamine into every cubic meter of water. Second and third generation worms and ring worm disease: these two worms attach a large number of gills and secrete a large number of mucus to hinder

First, rotifer: a large number of rotifers (hard to observe with the naked eye) attach to the Gill filaments, destroying Gill tissue, affecting respiration, and asphyxiation of fish fry. Prevention and control method: ① per cubic meter of water with 0.5g of copper sulfate and 0.2g of ferrous sulfate (can also be used only 0.7g of copper sulfate) dissolved in 40 ℃ of warm water and sprinkled all over the pool. ② per cubic meter of water is sprinkled with 0.5 g dissolved water containing 50% desenamine in the whole pool.

The second and third generation worms and ring disease: these two kinds of worms attach a large amount to the Gill and secrete a large amount of mucus, which hinders the breathing of fish fry. The main symptoms are Gill edema, hyperemia is dark, and there is a lot of mucus in the Gill. This disease often occurs in the high temperature season. Prevention and treatment methods: ① per cubic meter of water body with 10 grams of potassium permanganate solution to wash fish fry 10ml 15 minutes (water temperature 25ml 30 ℃), immediately after washing, add new water or replace more than half of the pond water. ② per cubic meter of water with 90% crystal trichlorfon 0.2g, baking soda 0.1g mixed dissolve the whole pool, apply again every two days.

Water mildew and Gill mildew: diseases caused by molds invading the body surface and Gill tissues of fish. The diseased fish has a white mouth and a white tail, the serious body surface is in the shape of "white hair", and the Gill filaments are pale and unable to swim. The disease occurs when the water temperature is low at the end of early spring and autumn, or when the skin of fish fry is injured after transportation or sieving. Prevention and treatment: 0.2 grams of malachite per cubic meter of water, 5 grams of baking soda and 50 grams of salt are dissolved and sprinkled in the whole pool, once a day for 2 consecutive days.

Fourth, bacterial enteritis: feeding unclean or deteriorated feed, getting sick by bacterial infection, sick fish tendrils, anorexia, fish blackening, swimming alone, severe abdominal swelling, or even mass death within a day or two. Prevention and treatment: can be fed with "Yubikang" mixed feed, 200 grams of medicine for every 50 kg of fish, once a day for three consecutive days. One gram each of erythromycin, chloramphenicol, furazolidone and 20 grams of salt can also be mixed into sticky feed once a day for 3 consecutive days. If fish anorexia is found, every cubic meter of water should be sprinkled with erythromycin and furazolidone 0.5 grams of dissolved water, once a day for 2 consecutive days.
