Sharing Experience on Artificial Propagation of Farmed Carp in Autumn
Carp can reproduce in both spring and autumn, but in conventional production, spring reproduction is the main approach. With the development of fishery production and changes in production models, reproducing fry only in spring is now far from meeting the needs of fishery production. Therefore, based on market demand, our farm has carried out carp fry propagation in both spring and autumn, and both have achieved good results. Below is an introduction to autumn carp fry propagation techniques for everyone's reference.

Practical and clever methods for trapping farmed rice field eels in winter
The winter market price of rice field eels is several times that of summer, so now is exactly the best time to bring rice field eels to market. Catching rice field eels in winter is very difficult. The vast majority of farmers catch eels by digging mud from the whole pond to take the eels, a method that is very labor-intensive, easily damages the eels

How to prevent and treat white head and white mouth disease in farmed grass carp
In home fish summer fry nursery ponds, the skin pigment from the tip of the snout to the eyeball of diseased fish fades to a milky white color, the lips appear swollen, and opening and closing become impaired, thereby causing difficulty in breathing. White head and white mouth disease is one of the serious diseases harming summer fry fish species (grass carp, black carp, silver carp, common carp, etc.)

Prevention and Treatment Methods for Gastroenteritis in Farmed Masked Palm Civets
Gastroenteritis is a severe inflammatory process affecting the superficial mucous membrane of the stomach and intestines as well as their deeper tissues. Because the anatomical structure and physiological functions of the stomach and intestines are closely related, organic damage and functional disorders of the stomach and intestines often affect each other, causing inflammation of the stomach and intestines to occur simultaneously or sequentially.

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.
