After entering the month of June, the temperature gradually increased and it was approaching the summer high temperature season. China Aquaculture Network reporter learned that the river crab breeding areas in Jiangsu, Anhui, Hubei, and other regions have been continuously experiencing drought for a long time. Coupled with the changeable weather in the first half of the year, the crab shells are not smooth and the losses are relatively large. This year's crab breeding situation is not optimistic. The crabs have entered a period of rapid growth in June. The management of crab breeding has the characteristics of high requirements and great difficulties. The relevant key work is now described as follows:
First, take measures to ensure good water quality In June, the pond water should be detoxified 1-2 times, and the pond sediment should be improved 2-3 times. The sediment modifier should be used to improve the surrounding area of ​​the pond and the feeding site to create a good bottom. surroundings. In June, the various types of aquatic weeds laid in the early stages of crab ponds were in a prosperous period. We should do a good job of maintaining aquatic weeds and take appropriate measures as soon as possible to strive for a close arrangement of aquatic plants in ponds. It can also reduce the amount of water weeds removed during the hot season. Ponds that grow turfgrass with black algae should determine the removal of the purse seine depending on the growth of their aquatic plants. The time is generally from the end of May to the beginning of June; Elodea in the ring ditch should be partially cleared and transplanted to prevent the rot in the hot season. Water quality is corrupted and disease is caused. In the process of removing Elodea, it should be done a small number of times and be removed at the same time to prevent the bottom of the pond from poisonous and harmful substances.
Second, bait feeding and water quality management June is the period of vigorous growth of crabs, in early June the third half of the crab shells basically ended, generally in late June to early July crabs have a shell process, June crab food intake Larger, the daily feeding should generally be controlled at about 8% to 12% of its storage pond volume. The feeding of bait is mainly focused on small fish, and the daily feeding amount of small fish is more than 2.5 pounds per acre. The proportion of animal feed, wheat, soybean meal, corn, etc., should be no less than 60%. Part of the inaccessible pond mouth should reduce the amount of small fish feeding, increase the amount of feed such as pellet feed.
The quality of crab ponds should be kept fresh, live, tender, and cool. The water level of crab ponds should be gradually increased depending on the growth of pond grasses. Water can be added once every two to three days. The average water level of crab ponds in mid-June should reach more than 50 cm until the end of June. Generally speaking, the crab pool reaches a higher water level. In June, lime can be splashed once to adjust the water quality. The amount of quick lime should not be too high. It requires about 10 pounds of lime per metre of water per acre to increase the calcium ion content of the water moderately. In June, when the temperature rises and crab activity increases, the water in the pool may become cloudy due to insufficient feeding or bad water quality. Take measures such as adjusting the quantity and variety of bait, adjusting water quality, increasing water level, appropriate fertilization, etc. Corresponding measures should be taken to keep the water quality of the pond fresh, and the transparency of the pool water should be maintained at about 50cm, which is conducive to the healthy growth of the river crab.
III. Disease control of river crabs June is a critical period for the prevention and control of river crab diseases. Prevention and control work should be carried out in conjunction with feed feeding, water quality control, and the construction of water ecological environment in the breeding process. In the use of drug control, the crabs will end in the third time. After the request to kill the crab pool, internal and external consumption of a comprehensive elimination of a time, the prevention and treatment of drugs should consider the resistance of cultured species, can choose to use different drugs in the early stage of control and efficacy of the same drugs. During the rainy season, the pond can be disinfected 1-2 times to reduce the generation of water-borne pathogens. After entering into June, it is a phase of extensive application of microbial preparations in crab ponds. It is also a period of good application of microbial preparations. It can be applied to crab ponds on a regular basis, generally applied once every 7-10 days, and can not only regulate water quality, but also maintain a good ecology of water bodies. The environment can also achieve the effect of preventing diseases.
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.
