Methods for Preventing and Treating Self-Biting Feather Disorder in Hwamei Breeding
(1) Causes of self-biting feather disorder in hwamei: The main causes of self-biting feather disorder in hwamei birds: ① The hwamei is a bird that loves cleanliness very much, and the vast majority love bathing (also called washing). If the hwamei is not bathed on time or regularly, if the cage is not cleaned frequently, if the sand grains in the sand tray are not replaced, if the birdcage and cover cloth are not cleaned frequently, and if there are prolonged rainy days and other such reasons, then lice or mites will breed on the hwamei. Lice and mites parasitize the surface of the hwamei's body, and the entire skin will be affected, causing the bird's skin to itch and bleed. The hwamei is “helpless” against the lice and mites breeding on its body, so it has no choice but to bite its feathers to stop the itching and bite its feathers to “vent its anger.” ② Because the hwamei has long been imprisoned in a cage, or has long been ignored and neglected by people, it is lonely all day and has no choice but to protest to its owner by biting its own feathers. Keeping a hwamei is not only for appreciating its fighting, but also for appreciating its beautiful feathers. Bald or messy feathers are really not beautiful, so how can its ornamental value even be discussed? ③ Some hwamei develop self-biting feather behavior because the bird keeper fed them feed ingredients such as caoguo and star anise. ④ Some hwamei develop self-biting feather behavior because their food lacks a certain trace element for a long time.</p><p></p><p>(2) Symptoms of self-biting feather disorder in hwamei: Tail feathers and wing feathers are incomplete and falling off, curled and uneven, or of uneven length, or the feathers have already been pulled off and bitten to pieces. The tail is bald or there are no wing feathers, and the exposed areas are red, swollen, and inflamed.</p><p>(3) Methods for preventing and treating self-biting feather disorder in hwamei: Once a hwamei develops self-biting feather disorder, carefully and thoroughly analyze the cause and treat it according to the symptoms. For example: ① Bathe the hwamei on time, and regularly clean the birdcage, sand tray, and cover cloth. Once lice or mites are found on the bird, immediately adopt a method of treating both internally and externally to eliminate them. Insecticides such as Baichongling can be sprayed on the birdcage, sand tray, and cover cloth to eliminate external mites; use disinfectant diluted with water or water boiled with local tobacco stems to bathe the hwamei and eliminate the lice and mites on its body. Adjust the concentration of the local tobacco stem water as appropriate, and bathing 2 to 3 times is enough. If the hwamei's skin is already red, swollen, and inflamed, grind Zailin or Yinqiao tablets (powder) into powder, put it into the water cup, and let the bird drink it for 3 days, which can reduce inflammation and relieve pain. ② If the self-biting feather disorder is caused by the hwamei being neglected, immediately set aside time to play with the bird, persist in walking the bird every day, and give the bird the opportunity to move outdoors or in nature to relieve its loneliness. ③ Analyze the feed the hwamei has eaten recently to see whether it may be lacking a certain trace element or whether it has been fed foods such as caoguo. If no lice or mites have bred and walking the bird has been maintained, then it must be a feed problem, and the feed formula should be revised promptly or another feed should be substituted.</p>

Prevention and Treatment Methods for Several Gill Diseases in Whiteleg Shrimp (Litopenaeus vannamei) Farming
1. Gill disease caused by Vibrio. Diseased shrimp float and swim slowly on the water surface, with gill filaments slightly swollen and dark gray, showing degeneration and necrosis at the tips. Under high magnification, actively motile bacterial cells can be seen. Ponds where this disease occurs have severely polluted bottom sediment and poor water quality, and the disease peak season is from July to September.

Control Methods for Taura Syndrome in Whiteleg Shrimp
Taura syndrome is caused by infection with Taura syndrome virus, also known as red body disease (typically, viral infection causes the body to turn red while the appendages do not; bacterial infection causes the appendages to turn red while the body does not; when both the body and appendages turn red, it may be a mixed infection). Sick shrimp stop feeding and swim slowly at the water surface

Methods to Improve the Survival Rate of Grass Carp Fingerlings in Grass Carp Farming
Whether grass carp are raised in monoculture or in polyculture with grass carp as the main species, the water quality must be kept fresh. Feed mainly with green feed and supplement with concentrated feed. Concentrated feed includes bran, beans, and compound feed, etc. During the initial stage of stocking (within 15 days), summer fry should be fed some fresh and tender aquatic plants, such as duckweed and watermeal.

What are the prevention and treatment methods for gill rot disease in pufferfish?
[Symptoms of gill rot disease in pufferfish] Diseased pufferfish move sluggishly, have darkened body color, have difficulty breathing, swim slowly in the upper water layer or near the pond edge, and have reduced appetite. When the gill cover is opened, increased mucus on the gill filaments is visible to the naked eye; in severe cases, the tips are decayed and defective, and some gill filaments appear grayish-white, often
