In 2008, the Shangxia Habitat Agricultural Technology Information Center in Shangyu City, Zhejiang Province implemented a technology-based household development process to store a farmer with 5 acres of ponds. 720 kg of fresh shrimp, 180 kg of white peony, total output value of 3861 O yuan, total net income of 21,860 yuan. The main technical measures are now described as follows:
The pond sited pond is located in Renxia Village, Zhenxia Town, Songxia Town. The soil quality is loam, close to the water source, sufficient water supply, good water quality, convenient irrigation and drainage, no pollution source within 3 km, and the water quality meets the standard requirement of NY5051, in which the dissolved oxygen reaches 5 Mg/L, pH around 7.5, convenient transportation and electricity.
The Pond Condition The pond is rectangular, east-west, slope ratio l:3, the bottom of the pool is slightly inclined towards the drain outlet, the pond mud is 10 centimeters, and water can be injected 1.5 meters, with an area of ​​5 acres. The pond is equipped with a 1.5-kilowatt impeller-type aerator and a 2.2-kilowatt submersible pump, and has a perfect intake and drainage system. There is a net fence around the ear water outlet, and the inlet and outlet openings are each wrapped with sieve boxes over 60 months to prevent wild fish and other predator organisms from influxing with the water and causing the shrimps to escape.
Qingtang disinfects and cleans ponds, drains pool water with a pump, removes excess sludge, retains 10 cm, and after exposure to fire, disinfects with 60 kg of quick lime. Use 100 kg per mu. Diluting the lime with water to make the pool evenly spilled. Then, stir and mix the silt and lime in the bottom of the pool with shovels to completely kill the wild fish, pathogens and pests in the pond. New water was poured on February 15 and 60 cm of water was poured for the first time. In order to cultivate sufficient plankton and benthic organisms, a total of 1500 kg of fermented and decomposed organic fertilizer was applied 7 days before the seedlings were planted in the lower pond. The amount of 300 kg per mu was used. Before stocking the second batch of fresh shrimp, all the fresh shrimps and white fishes in the pond should be out of the pool, and the tea seed cake can be stocked again after clearing the pond.
At the end of February, the stocks were stocked at 2500/kg, the body length was 2.5 to 3 cm, and the stocking rate was 12 kg/mu, which was approximately 30,000. Before stocking, soaking in 2% to 3 minutes with 3% saline solution, the stocked juveniles are free from disease, injury, body surface, clean, no attachment, bright body, appendages, strong vitality, and basic specifications. And let it go once. At the same time, appropriate amount of filter-feeding fish was provided in the pond. After 10 days, a total of 100 species of large-scale species of flower calyx and 200 species of white storks were adopted. In August, the second batch of shrimps was stocked with a total of 3,000 to 4000 tails per kilogram, a body length of 1.5 to 2 centimeters, and 13 kilograms per acre, which is approximately 45,500 tails. The shrimps are uniform in size and robust in physique. After being sterilized, they enter the pool, and half a month after they are released, a total of 1200 species of summer fishes are cultivated. Shrimp were soaked with salt 3# for 2-3 minutes before stocking.
The "shrimp nest" was set up in a shallow water zone 2 meters from the shore of the pool along the pool and in the pool. It was planted with aquatic plants such as peanuts, water spinach and water lettuce. The width of the grass was 1 meter. The water single belt was fixed with ropes to avoid The wind floats. Water grass. Before entering the pool, disinfect with bleach or copper sulphate solution to prevent enemies such as yellow clams, crayfish and wild fish from entering the pool. Aquatic grasses account for about 25% of the ponds. When aquatic plants thrive in summer, they will affect the photosynthesis of the surface air permeable and phytoplankton. Too much water weeds must be removed.
The first catch of commercial shrimp was caught in late May and the second batch of commercial shrimp was caught in late October.
Blood System:
Blood system is also called circulatory system.
For the treatment of diseases of the circulatory system:
According to the American Heart Association, cardiovascular disease is the leading cause of death in the United States. Because of its vastness and critical nature, it is one of the systems of the body most prone to disease.

One of the most common diseases of the circulatory system is arteriosclerosis, in which the fatty deposits in the arteries causes the walls to stiffen and thicken the walls. According to the Mayo Clinic, the causes are a buildup of fat, cholesterol and other material in the artery walls. This can restrict blood flow or in severe cases stop it all together, resulting in a heart attack or stroke.
Stroke involves blockage of the blood vessels to the brain and is another major condition of the circulatory system, according to Mitchell Weinberg of the North Shore-LIJ Health System. [Risk factors include smoking, diabetes and high cholesterol," he noted.
Another circulatory disease, hypertension - commonly called high blood pressure - causes the heart to work harder and can lead to such complications as a heart attack, a stroke, or kidney failure, the NLM noted.
An aortic aneurysm occurs when the aorta is damaged and starts to bulge or eventually tear, which can cause severe internal bleeding. This weakness can be present at birth or the result of atherosclerosis, obesity, high blood pressure or a combination of these conditions, according to Weinberg.
Peripheral arterial disease (also known as PAD) typically involves areas of narrowing or blockage within an artery, according to Jay Radhakrishnan, an interventional radiologist in Houston, Texas. In addition, chronic venous insufficiency (also known as CVI) involves areas reflux (or backward flow) within the superficial veins of the lower extremities.
PAD is diagnosed with noninvasive testing including ultrasound, CT scan, and/or MRI. Ultrasound is the least expensive of these methods, but also gives the least amount of detail, as CT and MRI show a much higher degree of anatomic detail when identifying areas of narrowing/blockage within an artery. CVI is diagnosed with ultrasound as the venous reflux can be measured accurately by ultrasound, which ultimately guides treatment.
