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

How to prevent and treat linear hepatic hemorrhage disease in farmed pufferfish
[Symptoms of linear hepatic hemorrhage disease in pufferfish] Sick pufferfish have a darkened body color, with the color from in front of the eyes to the snout noticeably paler; sometimes the body color of the pufferfish becomes pale while the area in front of the eyes becomes even paler and pallid. Sometimes the bases of the caudal fin, anal fin and dorsal fin are congested. When the abdomen of the fish is cut open, 1-2 obvious linear blood stasis marks can be seen on the liver, all extending upward from the left side of the abdomen to the right side. There is no food in the intestine, and the intestinal wall is sometimes slightly congested; sometimes severely affected fish show unusually frantic, random darting behavior, similar to the symptoms of white mouth disease in pufferfish. Linear hepatic hemorrhage disease in pufferfish has a high mortality rate, and there is currently no effective treatment method, so we adopt the policy of giving priority to prevention with treatment as a supplement. Regulate the water environment well, frequently siphon out waste, and frequently change the water, especially the bottom layer of water, which should be replaced regularly. When sick fish are found, remove and destroy them promptly. The following treatment measures were taken for the affected ponds and achieved certain results.

Prevention and Control Methods and Key Technical Points for Fulminant Disease in Cultured Puffer Fish
[Symptoms of fulminant disease in puffer fish]The main symptoms of diseased puffer fish are congestion at the base of each fin and in the fin rays; in severe cases, the fin rays, upper and lower jaws, eyes, and the area from the base of the dorsal fin to the caudal fin all show severe congestion. Sometimes there is bleeding in the orbital cavity and exophthalmos (bulging eyes). In some cases the gills show varying degrees of decay with abundant mucus.

A Detailed Guide to the Prevention and Treatment of Vibriosis in Farmed Pufferfish
[Symptoms of pufferfish vibriosis] The pathogen is Vibrio, with a growth temperature of 101Z-35C and an optimum temperature of around 25C; the growth salinity range is 0.5%-6%, and can even reach 7%, with an optimum salinity of around 1%; the growth pH range is 68, with an optimum of around 8. Diseased fish show gastrointestinal bleeding

Prevention and Treatment Methods for Iridoviral Fish Disease in Pufferfish
Iridoviral fish disease affects many fish during the high water temperature period in the farming of pufferfish juveniles and adults. Through observation of the iridovirus in diseased fish using Giemsa staining, iridoviral fish disease occurs concurrently with botulism and vibriosis, and is a viral disease caused by infection with bacterial and parasitic fish diseases.

How to Raise Fish and Ducks Together? Practical Farming Experience Shared
Fish-duck polyculture is mutually beneficial and is a new way to increase farmers' income. Ducks moving in the water can eat frogs, tadpoles, aquatic insects and other organisms harmful to fish; fish can make use of duck manure, leftover feed and other waste produced by the ducks, keeping the water clean and the environment good

Prevention and Treatment Methods for Gas Bubble Disease in Overwintering Common Carp Aquaculture
June to September is the peak period for fish disease outbreaks. In adult fish ponds, hemorrhagic septicemia of crucian carp (Carassius auratus) frequently occurs and endangers silver carp, bighead carp, and blunt snout bream (Megalobrama amblycephala), causing heavy losses to farmers. Conventional medication generally produces poor therapeutic results. After years of repeated observation and treatment, researchers

Prevention and Treatment of Hemorrhagic Disease in Crucian Carp Farming
June to September is the peak period for fish disease onset. In adult fish ponds, hemorrhagic fulminant fish disease in crucian carp often occurs, and it endangers silver carp, bighead carp, and blunt snout bream, bringing heavy losses to farmers. General conventional medication treatment is not very effective. After years of repeated observation and treatment, researchers

Two-stage farming of snakehead achieves high yields
The snakehead fish, also known as snakehead murrel or black fish, has high economic value, with the current selling price at 15-20 yuan/kg. Using the two-stage method of intensive pond farming for snakehead, we achieve a net income of 0.9-1.2 ten thousand yuan per mu. Snakehead is a fairly common fish in China, and many people like to eat it. The two-stage method
