Pathogen control in cold water fish culture
1. Establish a strict quarantine system when introducing and exporting fish eggs and fry, all aquaculture areas should strictly carry out quarantine to prevent and control the occurrence of diseases. Quarantine ponds shall be set up in breeding farms to isolate imported fish species, and only if there are no major diseases can they be temporarily reared. The quarantine pool is generally located at the end of the drain. The length of quarantine time should be determined by the transportation season, water temperature and disease characteristics. It takes 20 days when the average temperature is not less than 12 ℃, and it can be shortened when the water temperature is high, which is determined according to the lower the temperature, the longer the incubation period. If transplant

Six conditions affect the feeding of fish
In the process of intensive fishery production, the management of feed feeding is one of the main links in the whole production management, and the decrease of feed intake of fish often occurs in the process of feed feeding. According to the different conditions in the production, the reasons for the decrease of feed intake of farmed fish are as follows: the first situation: the fish is suffering from the disease, which leads to the decrease of feed intake of fish. Such as Carassius auratus endosporidiosis, grass carp three diseases, spotted forktail disease, enteritis and other diseases, the food intake of fish decreased significantly.

Aquatic bacteriosis of brocade carp
The term "mycosis" is often heard, and there are many examples showing that even mammals led by humans are difficult to cure the disease. The so-called "fungi" mainly refers to algae and fungi, or aquatic bacteria and filamentous bacteria that belong to incomplete fungi. This fungus is attached to the remains of animals and plants, and uses the remains as a source of nutrition to grow linear hyphae. This kind of hyphae belongs to inferior plants that do not contain chlorophyll. According to the report of the Society, there are more than a dozen kinds of hyphae, such as aquatic mycosis. What I want to discuss here is that

The three hurdles of parent fish in summer
The Beginning of Summer to Lesser Fullness of Grain is the best time for parent fish to induce spawning. at this time, the water temperature is suitable, the spawning rate and hatching rate of parent fish are high, and the survival rate of fry is also high after entering the pond. If we seize this favorable opportunity and strictly control the selection of parent fish, the use of drugs and the management of induced labor, the success of induced labor can be achieved. Whether the mature parent fish is mature or not determines the effect of spawning. When selecting parent fish, its maturity is generally identified according to its external characteristics. The belly of mature female parent fish is swollen, round, soft and elastic.

Fish ball processing technology
Fish balls taste delicious, nutritious, is a delicacy on the table, especially suitable for the elderly and children to eat. To process high-quality fish balls, the following points must be grasped technically: processing fish balls should use fresh fish weighing 1500 yuan-4000 grams. Because the fish is too small, the finished product is not smooth and tender; if the fish is too large, the meat is old and not refreshing. The fish will be selected to scale, gills, internal organs, cut off the head, leaving fish, pick out small thorns. Rinse the clean fish for half an hour to remove blood stains

Intensive cultivation of parent fish in spring
Spring is the key period for the gonadal growth of parent fish, and the quality of parent fish cultivation at this stage is directly related to the success or failure of artificial reproduction of domestic fish, so on the basis of usual cultivation, we should pay special attention to spring cultivation. 1. Adjust the water level of the parent fish pond and increase the water temperature. Timely drainage on a sunny day to reduce the water level of the fish pond and accelerate the increase of the water temperature of the fish pond. The displacement can reduce the water level of the fish pond by about 30 cm. When cloudy and rainy days or cold air comes, fill the pool water in advance to slow down the heat dissipation. two。 Strengthen feeding management and investment

Comprehensive Utilization of scraps from Fish processing
The remaining fish head, fish tail, minced meat, scales, skin, viscera, bone, gallbladder and so on, contain a lot of protein, amino acids, trace elements and vitamins. Using these protein resources, a variety of deep processing products can be made, including soluble edible fish protein meal, liquid fish protein feed, fish scale glue, fish skin glue, bone paste, fish protein calcium sugar, bile pigment calcium salt and bile salt, etc. Comprehensive utilization of fish processing leftovers can reduce the cost of leading products, increase the added value of aquatic products, maintain the environment and reduce waste.

Prevention and treatment of pig dysentery poisoning
Dysentery is often used to treat gastrointestinal infectious diseases, such as porcine paratyphoid and so on. The dosage of pigs is 0.007 grams per kilogram of body weight, which is taken orally for 2 to 3 times. Son pigs are more sensitive to dysentery, which can cause acute or chronic poisoning when fed too much or used for a long time. After poisoning, the pig lost appetite, weak limbs, unstable standing, walking swaying, front and back limbs extended outward, skin temperature decreased, slow response, coma, muscle trembling all over the body. When the dead pigs were examined, it was found that the gastric fundus mucosa had severe inflammation.

Changes of Antibody to Porcine Circovirus Type 2
There were two peaks of antibodies against porcine circovirus, one was maternal antibody at 1~2 weeks of age, the other was maternal antibody at 8~10 weeks of age, which was caused by circovirus infection, and then the antibody level decreased to undetectable at the stage of big pig, which also indicated that the virus infection was slight at this stage. Porcine circovirus infection is very harmful to pigs. The period of low health level of pigs coincides with circovirus infection in time. This is our strict prevention against immune failure and secondary infection.

A brief introduction to the main points of prevention and treatment of duck heatstroke
Duck heatstroke, also known as heat stress, is an acute disease caused by disturbance of heat dissipation mechanism and destruction of heat balance in ducks under the condition of high temperature and high humidity. If the disease is not dealt with in time and effectively, a large number of ducks will die, thus causing greater economic losses to breeding. The main causes are as follows: 1. The temperature in summer is too high, or the humidity increases after the rainstorm, and ducks are most likely to cause heatstroke under the combined action of high temperature and high humidity. 2. There are no shading facilities in the duck's sports ground, which makes the duck stay in the strong sun for a long time.
