How to cultivate Artemia in indoor water?
The culture water must be sieved (gauze, glass wool) or sand filter. Where there is no seawater, it can be prepared with well water and coarse salt. The salinity is 30-75 ‰. If high density is not used for water culturing, then it is used to add carbonic acid. Salt (2 g/l) natural sea water, water temperature is maintained at 25-30 °C. The tank is slightly ventilated or stirred several times a day to increase the dissolved oxygen in the water. The stocking density of newly hatching nauplii is generally 100-500 individuals/liter; in high-density cultivation, 10,000 individuals/liter can be stocked, and 2,000 individuals/liter can be stocked in flowing water. Inoculate in the afternoon. Feeding Artemia can use dry powders or pastes with a particle diameter of less than 50 microns. Must be very low in the cultivation of water solubility, such as rice bran, soy flour and flour 1:1 mixed powder, spirulina and other dried algae powder, yeast, bean dregs powder, starch mash and so on. It is also possible to fertilize unicellular algae, ciliates, protozoa, bacteria, etc. as feed. During the cultivation, it is necessary to ensure the supply of bait. Feeds must be replenished in time. Usually twice a day, high-density culture is best for 1 hour, because halogen Insects are continuous feeding filter feeders. The constant density of bait can maintain a faster growth and higher bait conversion efficiency.
The transparency of water for cultivation is a useful parameter for determining the optimum amount of feed. When feeding granular rice bran, the transparency of the rice bran suspension should be maintained at 15-20 cm. Feeding once per hour, you can keep the density of day and night bait stable, culture for 14 days, a total of 4 kg of rice bran dried powder, such as feeding yeast, the amount can not be too much, per cubic meter of water, cast 100-150 grams per day, summer Should invest less in the cultivation process, in the cultivation process, the bottom of the container deposit residual bait, Artemia excrement and the skin under the arm, affect the water quality, but also hinder the Artemia bait, the fourth day should continue to be the particle waste Removed from the culture fluid. The funnel-shaped container can be opened to clear the bottom stopper, and can also be removed by siphoning. The drain tube is attached to a sieve. The size of the mesh is replaced by the growth of the Artemia, that is, from 200 microns to 250, 350, and 450 microns, as far as possible. The soil was sucked out without missing Artemia. On the 6th day of culture, the Artemia was started to move and the filtration rate was greatly increased. The amount of dissolved oxygen and pH were measured regularly. When the dissolved oxygen was reduced to 2 ppm, the PH value was reduced. 7.5 or less, need to increase the amount of aeration or add sodium bicarbonate, according to the water quality can also change the water, can be changed for 2-3 days, each time 1/3 - 1/2, after 2 weeks of culture, halogen The average length of worms can reach 7-8mm.
Harvesting can use Artemia to surface respiration to harvest Artemia before adulthood. The method is to stop the aeration, without agitating the culture water. The amount of dissolved oxygen in the water gradually decreases. After about 30 minutes, the oxygen content in the culture medium reaches a critical value, and the Artemia is dense to the surface of the water. At this time, the Artemia can be obtained by using a dip net. reward. From nauplii to large-scale Artemia before adulthood, the output can reach 2-5 kg ​​(wet weight) per cubic meter of water.
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.
