The rapid culturing of grass carp by Xiaotang living water is a new technology for fish farming that has emerged in recent years. Generally 0.1~0.2kg of fish species, after 5~6 months of Xiaotang Dahuoshui intensive breeding, each end up to 1.5~3kg, the second year up to 6.5~8kg, a small pond (30 square meters) Can produce 200~300 kg of fresh fish.
Digging ponds in selected areas: Selecting long-term clear water and irrigation and drainage management are convenient, and are not subject to mountain flooding, and small ponds are excavated by sticky soil on both sides of the house and non-leakage land. According to the conditions of the plot, dig small ponds 20 to 30 square meters in size and 70 to 80 centimeters deep. The ponds should be built with no leakage, open the influent trenches (preferably dark trenches), and be buried in and out of the water pipes. The water outlet is buried in a water pipe and it enters the house. Immediately after the digging of the pond, a fence was erected to protect against theft and poultry and livestock.
Fostering fry: Before opening Xiaotang, we must breed 0.1~0.2 kg of healthy, disease-free, non-injury, uniform-sized fry, with 400 to 500 fish ponds per unit, which can be raised by the villagers' groups or individually. Joint fish breeding to reduce costs and increase income.
Good feed: Every 30 square meters of small pond raising grass and grass, 400~800 square meters of forage grass need to be planted, Sudan grass and goose vegetables are planted in spring, and ryegrass is also planted in autumn, and grass is also cut to meet the needs of grass carp green feed. .
Xiaotang disinfection: generally 1.5 to 2 months before stocking fish species, 15 kg of mature lime per 30 square meters, 60 kg of human urine, can be dried. Xiaotang irrigation fish after 3 days. This will increase fish disease resistance and survival.
Efficient management: To ensure long-term irrigation of small ponds with large springs, pond water should achieve long-term string irrigation, which is the key to live fish in small ponds. If the water supply is insufficient, a small reservoir can be opened to catch the spring rainy season and reserve good water. In this rainy season or during drought season, it is also possible to ensure that fresh spring water can be used for irrigation and promote rapid fish growth. Time is from 8 to 9 o'clock in the morning and 2 to 3 o'clock in the afternoon; quantitatively, 1.2 to 1.5 times of the total mantissa is to be placed; positioning, feed frames should be placed at the center of the pond, and the feed should be fed within one hour after the feed is released. Put it up and throw away the residue. In the hot summer season, it is in the cool morning and late afternoon. And put a pergola on the delivery box to avoid the hot sun drying materials to facilitate grass carp eating and increase appetite. To train fish to prevent fright, go to the pond every morning, evening, evening, and after 20 to 30 days, the fish will no longer be runaway, and people will go to the pond to catch and fish. It will not move. , so even if the training is good, so that the fish quietly and quickly grow. Fish disease prevention. Fish seedlings were immersed in 2 to 4% salt water to disinfect the fish before the ponds. In addition to insisting that the remaining grass was removed after each feeding of forage grass for one hour, the bottom remnants and waste foods were thoroughly removed once every half month. To put garlic, spicy ingredients, wild gynostemma, and promote healthy and rapid growth of fish. It is necessary to constantly inspect and reinforce the fence to prevent theft and the intrusion of poultry, livestock, and wild animals into the pond.
Precautions: If the water temperature is lower after the fish is under the pond, you should feed cooked sweet potato mixed rice bran or wheat bran, or feed the fish pellet feed, in order to ensure the longevity of the fish; Xiaotang should insist on pure grass carp. To achieve high quality and high yields. If the miscellaneous fish should be set up, a miscellaneous fish pond should be used for live water aquaculture. After the grass carp grows to 1.5 kg, the size of the fish can be kept small every day and the density of the sparse fish can have a certain effect on high-quality and high-yield production. If the water source is insufficient, spring rain can be caught. During the season, assault stocking for 3 to 4 months, each fish can grow to 1 to 1.5 kg.
AZETROMAX injection is a broad semisynthetic bactericidal macrclde synthesized from tylosin.It has an spectrumthat is predominantly Mycoptasma,Pasteurella and various Gram-positive as Staphylococcus app.
Bromhexin has strong mucolytic effect. It mainly acts on mucus producing cells of tracheal and bronchial mucosa, inhibits the synthesis of acidic mucopolysaccharide in sputum, and breaks mucin fibers in sputum. Therefore, the rheological characteristics of tracheal and bronchial secretion return to normal, mucus is reduced, sputum dilution is easy to cough. The expectorant effect of this product is still related to its promotion of ciliary movement of respiratory mucosa and its nausea expectorant effect. It takes effect about 1 hour after taking the medicine, reaches the peak in 4 ~ 5 hours, and the curative effect lasts for 6 ~ 8 hours. It is used for patients with white sticky sputum and difficult to cough up, such as chronic bronchitis, asthma, bronchiectasis and silicosis. Patients with purulent sputum need to use antibiotics to control infection.
Timicosin is a semi synthetic macrolide specific antibiotic for livestock and poultry developed in the 1980s. It is mainly used to prevent and treat livestock pneumonia (caused by Actinobacillus pleuropneumoniae, Pasteurella, mycoplasma, etc.), avian mycoplasma disease and mastitis of lactating animals.
Azithromycin is suitable for the following infections caused by sensitive bacteria: lower respiratory tract infections such as bronchitis and pneumonia; Skin and soft tissue infections; Acute otitis media; Sinusitis, pharyngitis, tonsillitis and other upper respiratory tract infections (penicillin is a common drug for the treatment of suppurative streptococcal pharyngitis and for the prevention of rheumatic fever. Azithromycin can effectively remove Streptococcus in the oropharynx, but there is no data on the efficacy of azithromycin in the treatment and prevention of rheumatic fever). Azithromycin can be used for simple genital infection caused by Chlamydia trachomatis in sexually transmitted diseases of men and women. Azithromycin can also be used for simple genital infection caused by non multidrug resistant Neisseria gonorrhoeae and chancre caused by Haemophilus Duke (co infection of Treponema pallidum should be excluded).
