1. Selecting and nurturing relatives that are currently used for breeding are harvested from reservoirs and lakes using fishing tools such as cages and clams. Because there is a unique sexual reversal phenomenon in Astragalus, 100% discrimination between male and female has a certain degree of difficulty. General male body length chooses 40cm or more, 50cm or so is best, and female body length chooses about 25cm. Intimate body requirements for a robust shape, bright yellow body color, lower abdomen enlargement and soft, ovarian contours, abdomen was light orange, red genital hole swollen.
The female and male fertile cubs were separately cultivated at the ratio of 2:1 or 3:1. After the pro-chondrite pool was cleaned and sterilized, 20-25 pro-casps were released per square meter. After artificial breeding of cocoon and other animal foods, during the cultivation period, attention should be paid to infusing new water, adjusting the water quality, and keeping the water depth of 10-25cm better. Change the water twice a week, changing the water for 1/3 each time to ensure long Time micro-flowing water is conducive to the normal development of gonads.
Second, oxytocin and hatching
1. Aphrodisiac spawning: When the water temperature reaches 25-28 degrees Celsius, the production is induced by the injection of human chorionic gonadotropin solution, 400-500 international units (IV) are injected per female, and the male quail is halved. The injection method is intraperitoneal injection. The effect is good and the effect time is short.
After intimal injection, the female and male prostitutes are given a ratio of 2:1 or 3:1 and put into the spawning pond for 45-50 hours to produce or extrudate eggs. When artificial insemination is performed, females are usually bred first. The eggs (squeezed out eggs or cesarean) were then dissected and the semen was removed for dry insemination.
2. Incubation management: The optimum water temperature for hatching is 22-28 degrees Celsius. In the most suitable range, the higher the temperature, the higher the hatching rate. Generally, at 25 degrees Celsius, hatching takes about 150 hours (7-8 days). Newly hatched seedlings, with a total length of 12-20mm, can be placed in nursery ponds for 3-4 days after hatching. The temperature difference between the two water temperatures should not exceed 3-5 degrees Celsius.
Third, seed cultivation:
The seedlings were placed in a nursery pond and after the yolk sac gradually disappeared (about 1 week or so), zooplankton (clasps, copepods, and some large rotifers) were started to feed and later transferred to cooked egg yolks and flour. Paste feeding, can also be used for meat, quail, a variety of animal blood and scraps processed into a paste evenly into the pool, fed 4-6 times a day, daily feeding amount of 2-5% of the fish body weight, If the stocking amount is 450-500 tails/m2, 20-40 tails/kg can be harvested in the winter.
4. Water Quality Regulation Although the seedlings are resistant to sewage, hypoxia, and disease resistance, in high-density intensive farming, water quality adjustment must be paid attention to, and water injection or flushing water should be used once a week. Each change of water accounts for the total pool water. 1 / 3, in the summer season can be planted in the nursery pond mushroom, white peony, water peanut or peony, play a shade effect. A small amount of seedlings can also be put in the pool, with a density of 30-50 tails/m2, which can effectively remove the residual food, and play a role in controlling the water quality and reducing the effects of young wandering.
Fifth, the prevention of rickets to prevent rickets in order to prevent the main, before the seedlings into the pool, the pool cleaning and disinfection, while with 3-4% of salt water bathing seedlings 2-5 minutes, the general young quail disease is not much.
Saprolegniasis, also called skin mildew, is caused by infection of the wound with water mold caused by the bite of the larvae or the invasion of predators. Once infected with watery mildew, the offspring have a white hairy appearance, commonly known as "green hair" or "white hair disease." The disease manifests as irritability, muscle rot in the affected area, loss of appetite, and finally gradually thin and dead. Eggs that are infected with water mold will also cause large numbers of eggs to die.
Control methods:
1, each cubic meter of water with salt and NaHC03 each 400g, Quanhua Quanchiposa, even sprinkled for three days.
2. The quail eggs were dipped in a 0.7 ppm malachite green solution for 10-15 minutes and used continuously for three days.
Cardiovascular:
Relating to the circulatory system, which comprises the heart and blood vessels and carries nutrients and oxygen to the tissues of the body and removes carbon dioxide and other wastes from them. Cardiovascular diseases are conditions that affect the heart and blood vessels and include arteriosclerosis, coronary artery disease, heart valve disease, arrhythmia, heart failure, hypertension, orthostatic hypotension, shock, endocarditis, diseases of the aorta and its branches, disorders of the peripheral vascular system, and congenital heart disease.Related Products:cardiovascular drugs.
Urinary:
For the treatment ofl some diseases of the urinary system.
Different specialists treat urinary system ailments. Nephrologists treat kidney diseases, while urologists treat problems with the urinary tract, including the kidneys, adrenal glands, ureters, bladder and urethra, according to the American Urological Association (AUA). Urologists also treat the male reproductive organs, while gynecologists often treat urinary diseases or disorders in females, including yeast infections. Nephrologists and urologists often work with endocrinologists or oncologists, depending on the disease.
Urinary tract infections (UTIs) occur when bacteria enters the urinary tract and can affect the urethra, bladder or even the kidneys. While UTIs are more common in women, they can occur in men. UTIs are typically treated with antibiotics, according to Dr. Oscar Aguirre, a urogynecologist in Denver.
Incontinence is another common disease of the urinary system. It can come in the form of a pelvic prolapse, which can result in leakage and can be the result of a vaginal
delivery. Then there is the overactive bladder, [which we see a lot and is not related to having children or trauma," Aguirre said. A third condition involves overflow, in which the bladder does not completely empty.
Some common treatments involve medications, physical therapy and pelvic mesh surgery, Aguirre noted. Vaginal laser surgery is also becoming a viable treatment option, he explained. [In another 10 to 15 years, vaginal laser surgery will be another common option for the treatment of urinary conditions."
Interstitial cystitis (IC), also called painful bladder syndrome, is a chronic bladder condition, primarily in women, that causes bladder pressure and pain and, sometimes, pelvic pain to varying degrees, according to the Mayo Clinic. It can cause bladder scarring, and can make the bladder less elastic. While the cause isn`t known, many people with the condition also have a defect in their epithelium, the protective lining of the bladder.
Prostatitis is a swelling of the prostate gland and, therefore, can only occur in men. Often caused by advanced age, symptoms include urinary urgency and frequency, pelvic pain and pain during urination, the Mayo Clinic noted.
Kidney stones are clumps of calcium oxalate that can be found anywhere in the urinary tract. Kidney stones form when chemicals in the urine become concentrated enough to form a solid mass, according to the Cleveland Clinic. They can cause pain in the back and sides, as well as blood in the urine. Many kidney stones can be treated with minimally invasive therapy, such as extracorporeal shock wave lithotripsy, which disintegrates the kidney stones with shock waves.
Kidney failure, also called renal failure and chronic kidney disease, can be a temporary (often acute) condition or can become a chronic condition resulting in the inability of the kidneys to filter waste from the blood. Other conditions, such as diabetes and hypertension, can cause chronic kidney disease, according to the Mayo Clinic. Acute cases may be caused by trauma or other damage, and may improve over time with treatment. However, renal disease may lead to chronic kidney failure, which may require dialysis treatments or even a kidney transplant.
Bladder cancer is diagnosed in about 75,000 Americans each year and is more frequent in men and the elderly according to the American Cancer Society. The symptoms, including back or pelvic pain, difficulty urinating and urgent/and or frequent urination, mimic other diseases or disorders of the urinary system.
