First, the election pool clear pool
In cages raising yellow peony root, the yellow peony grows hyperthermic, sheltered, dark, and scared. Therefore, cage culture should choose sunny, sheltered, convenient water sources, less external interference, an area of ​​3-5 acres, water depth of about 1.5m, the water level should be relatively stable ponds. Before stocking, the ponds need to be thoroughly disinfected with quicklime 100-120kg/mu to kill harmful microorganisms and improve sediment quality.
Second, the cage settings
The cage depends on the pond. The cage is set in the middle of the pond. The four corners are fixed with bamboo. The four sides are tied with bamboo and bamboo. The bamboo and the four corners of the bamboo knot make a joint so that the water can rise and the water can drop. The depth of the cage is about 10m deep, and the upper edge of the cage is 0.5m away from the surface of the water to prevent the yellow locust from fleeing and to manage the daily buoys. The total area of ​​the cage should not exceed 50% of the pond area.
In one week before stocking, the cages were put into the water first to allow the cages to attach some algae to avoid damage caused by the rubbing of the carcass and the mesh. At the same time, the breeding of the water peanuts, water hyacinths, and oil grasses in the box was faster. The aquatic plants provide a good environment for the stocking of the seedlings. The area covered by aquatic weeds is 80%-95%. If water grass grows slowly, it can be properly applied to promote growth. Feishuibao is good for cultivating good water quality that is fat, live, tender, and cool, which is conducive to raising the survival rate of the seedlings and eating early.
Third, seed selection and stocking
1. Seed selection. The species requires no scars on the body surface, normal body color, and agile activities. Attention should be paid to the removal of the disease, and drug-fishing and fishing should not be required. Acquisition specifications are preferably 20-35 grams per tail.
2. Seed disinfection. When immersed in the pond, use 8% to 10% salt solution for 3 to 5 minutes, or 3% to 4% salt solution for 10 minutes to kill the body surface bacteria to avoid the introduction of exogenous pathogens. Farming ponds.
3. Seed stocking. There is a large habit of eating a small yellow pupae, the individual specifications within the same cage can not be too much difference, the amount of each cage is 3 to 4.5 kilograms, a one-time release. According to the weather conditions and the temperature, stocking time is concentrated from July 10 to mid-August. When stocking quail species, about 10 muddy cultivars can be mixed in each tank. 80 to 100 squid and 20 to 25 squid per mu can be placed in the pond to clean up the bait and adjust the water quality.
4. Sort regularly. The jaundice in the cage is generally sorted once every two months, so that the specifications of the jaundice in the same cage are basically the same to avoid uneven eating and promote balanced development.
Fourth, feed the bait
Feeding insists on the principle of "during the four orders and four observations", namely, "timing, qualitative, quantitative, and positioning" and "see the season, see the weather, see the water quality, and see the appetite."
1. Tame food. The newly acquired wild astragalus has a smaller intestine, and it requires an adaptation period of 2 to 3 days after stocking. Therefore, it is fed at a small amount and gradually domesticated. Normally after 7 days of domestication, Astragalus can normally feed.
2. The type of bait. The main feed is chilled fish (ensure no spoilage) and fresh small scads, which are processed into meat pupa and then placed on water peanuts to facilitate the feeding of jaundice. Once fed with unclean or decayed bait, it is very likely to cause jaundice to refuse to feed or get sick, especially during hot summer months.
3. EM bacteria bait. Each day, 6% of the fish broth can be mixed with EM liquid (homemade with EM raw brown sugar).
4. Feed the bait. The specific feeding amount is shown in the attached table. Each feeding amount is appropriate within 30 minutes. The feeding time is selected to be darker in the sky after sunset. Day or sweltering and windless days less vote. After feeding for 1 hour, check the feeding situation again. If the meat has not been eaten, remove it in time to avoid damaging the water quality. The amount of 1 feeding is generally adjusted every 10 days. In the breeding process, the feed coefficient for chilled fish is approximately 4.5.
V. Daily management
The cage should have a certain degree of fatness in the body of water that raises the Astragalus membranaceus. The transparency should be controlled between 15 and 20cm. Over-saturation of water will affect the growth of Astragalus membranaceus. In order to improve the water quality and improve the utilization rate of ponds, the box should be cultured in time, such as oysters, oysters, clams, and grass carp. Observe the ground regularly to check the bottom of the tank periodically and find that the dead worm should be promptly removed. Once the cage breaks and the onset of jaundice occurs, repair and treatment should be carried out immediately.
During the high temperature period in summer, the carp eats heavily, excretion is large, and the water quality is easily corrupted. This stage should be mainly controlled by water quality and summer cooling. Remove the residual baits in time every day, clean the nets when necessary, and change the bottom water when changing the water. For those with poor water quality, where the bottom of the pool is aging and there is no water to be exchanged, Haizhong Baoqiang should be used frequently.
Purify water quality. The plants in the tank must also remove the aging part, promote the growth of new grass, and enhance the water purification function of aquatic plants. In autumn, the water temperature begins to slowly decrease, and the aquatic plants begin to age. Therefore, aging plants should be removed in time, and 1/7 of the water surface should be set aside for drying in order to increase water volume and improve water quality.
The decrease of water temperature in winter, the aging and rot of aquatic plants, the increase of breeding density, and the deterioration of water quality have led to a significant decline in the immune system of jaundice. Therefore, it is particularly important to add proper amounts of auxin and other drugs to improve the disease-resistance of fish before wintering. At the same time during the winter, the use of strong poison net, Shencao Dan, anti-virus disinfectant and other disinfectants to disinfect the water, Haizhong Po water purification work can not be ignored, in order to ensure the safe winter through the Huang Qi.
Sixth, science and disease prevention
In the process of raising jaundice in cages, we must follow the 12-character principle of “disease-free early prevention, disease-preventing first treatment, and prevention-preventive treatmentâ€. Regularly use oral liver granules and other health-care drugs to improve the immunity of fish and use it regularly. Disinfectants are used for water disinfection, oral sterilization, and insect repellent drugs for disease prevention and treatment.
There are many causes of the occurrence of salmon, summarized in the following areas:
(1) Causes of Dianchi Lake: The newly built Dianchi Lake had not been soaked in fresh water for a period of time. The water quality was not stable, and the fish was immediately released to raise the water, so that the carp could not adapt to the disease quickly. Or the old Dianchi pool is not clear for a long time, too much humus, water quality is corrupted, and it creates good conditions for the proliferation of pathogens.
(2) Mutation of water temperature: Huangqi is suitable for survival at 15°C-30°C. Due to the small area of ​​Dianchi Lake, large changes in water temperature during the day and night, and the high temperature season in summer, the water temperature is sometimes as high as 40°C or more, and it is often the phenomenon of “burnout†of the jaundice. In addition, because Dianchi Lake often needs to add new water, changing the water volume will lead to sudden changes in water temperature, which will affect the growth of carp. If the water temperature drops sharply by about 4°C, the carp can easily cause a “coldâ€. Mutations in the weather can also cause illness.
(3) Excessive harmful substances: In the high temperature season, large feeding amount and large amount of jaundice are discharged, and a large amount of organic matter is deposited on the bottom of the pool. The decomposition of organic matter consumes a large amount of oxygen in the water, resulting in oxygen deprivation. The organic matter is forced to undergo anaerobic decomposition, resulting in a large amount of harmful gases such as ammonia gas, hydrogen sulfide, and biogas. At the same time, the anaerobic bacteria proliferate in large numbers and infect the carp, leading to disease.
(4) Causes of Feeding Technology: Huang Xi prefers to eat fresh bait. If unclean or rotted feed is dropped, it will cause jaundice. If the amount of feed is insufficient, or if the food is not thoroughly eaten, jaundice will show signs of fratricide.
(5) Improper use of drugs: Astragalus membranaceus is scaleless fish, its physiological characteristics, the resistance of the drug is very different from the scale fish, if the disinfectant, soaking the drug is too irritating, it will damage the surface of the jaundice mucus, jaundice Physical fitness and immunity are reduced, and it is very easy for harmful bacteria to invade the body and cause illness. Prevention of internal medicine should be based on health-care medicines and Chinese herbal medicines, and prevention should be made from the viewpoint of enhancing the physique of jaundice and increasing immunity.
Seven, matters needing attention
1. Rats bite the box. It is advisable to set up anti-escape facilities with reference to river crab ponds around the pond to prevent water rats from entering and breaking the tank. As long as there is a small hole in the cage, most of it will escape into the pond, affecting feeding and growth. Pay attention to the daily patrols and feedings, and if there is a hole in the cage, repair it immediately. Conditions can be set at the pool edge rat clip.
2. The cage should be launched in advance. The cages must be put into the water for two months prior to stocking. The first is to facilitate the attachment of a small amount of algae organisms to the cabinet, to make the cabinet smooth, avoid scratches when the seedlings enter the container, and to reduce or eliminate the odor emitted by the polyethylene mesh. So as to reduce the sensitivity of yellow peony to plastic.
3. The meat must be fresh and soft. Huang Xi likes to eat fresh bait, and the chilled fish to be fed should not be spoiled; at the same time, due to the habit of eating jaundice, the meat must be soft and thin, removing large fish bones.
Radial Artery Compression Devices
Radial artery compression devices, also known as radial artery compression devices or wristbands, are used to achieve hemostasis after a transradial cardiac catheterization procedure. The device is applied to the wrist and inflated to compress the radial artery, which is the artery that supplies blood to the hand and fingers. This compression helps to prevent bleeding and hematoma formation at the site of the catheterization.
Radial artery compression devices are preferred over traditional compression methods such as manual compression because they are more effective, comfortable for the patient, and allow for earlier ambulation and discharge. They also reduce the risk of complications such as radial artery occlusion and nerve injury.
In addition to cardiac catheterization procedures, radial artery compression devices may also be used after other procedures that involve the radial artery, such as transradial access for arterial blood gas analysis or for the placement of intra-arterial lines.
