How to Prevent Crab Death in Autumn

Every fall, the crabs have entered the season of maturation and harvest, and they have also entered the stage of death. If you do not pay attention to strengthening management, there may be significant losses due to batch death of crabs. How to prevent the autumn death of crabs? This starts with the following three aspects: (i) Preventing natural deaths: As the saying goes: “Since the West Wind, Crab Feet Itches”, from September to November each year, a group of crabs that have been growing for two years are removed from the “Yellow Crab”. The shell becomes "green crab" and the gonads mature and enter the final period of life. All crabs with “foot itch” have been unable to adapt to the environment of low osmotic pressure due to maturation of gonads and increased osmotic pressure in the body. Such crabs must escape to find a new environment, and eventually they will naturally die. These crabs should be arrested and sold in time to avoid losing their economic value due to natural death. (B) Prevention of indigestion death: After the fall, the temperature difference between day and night, pressure, water temperature changes will also increase, the crab's appetite will change, easily lead to indigestion and death. This is what is usually referred to as "bloat death." In severe cases, it may lead to total death. Prevention methods include: improving water quality, regularly disinfecting with lime water; regularly adding antibiotics and auxin in food, not feeding or feeding plant foods; feeding should be done regularly and quantitatively. When the water temperature drops, the amount of feeding should be reduced accordingly. (C) to prevent the "cold" death: autumn, day and night temperature changes, the water temperature difference is also large, and sometimes even a difference of 10 °C, crab is not adaptable, easy to "cold" and cause breathing difficulties and death. Prevention methods are: pay attention to regulating the water level to prevent drastic changes in water temperature; the temperature difference when injecting new water should not be greater than 3°C; the water surface should be longer than some water hyacinths, water peanuts and other cover plants, but the coverage area can not be greater than 1/2 of the water surface; when the weather changes To deepen the water level.

For the treatment of diseases of the Digestive System:

Many symptoms can signal problems with the GI tract, including: abdominal pain, blood in the stool, bloating, constipation, diarrhea, heartburn, incontinence, nausea and vomiting and difficulty swallowing, according to the NIH.

Among the most widely known diseases of the digestive system is colon cancer. According to the Centers for Disease Control (CDC), 51,783 Americans died from colon cancer in 2011 (the most recent year for available data). Excluding skin cancers, colon and rectal cancer, or colorectal cancer, is the third most common cancer diagnosed in both men and women in the United States, according to the American Cancer Society.

Polyp growth and irregular cells, which may or may not be cancerous, are the most common development paths for colorectal cancers (also referred to as CRC), and can be detected during a routine colonoscopy, according to Dr. John Marks, a gastroenterologist affiliated with the Main Line Health health care system.

[The best news is that, if caught early enough, they can also be removed during the colonoscopy - eliminating the possibility that they grow further and become cancer," Marks said.

For those patients whose cancer has already spread, there are various minimally invasive surgical options that have extremely good prognoses. It is recommended that asymptomatic patients without a family history begin getting tested regularly between the ages 45 and 50, according to Marks. [Symptoms which may suggest that you need a colonoscopy at an earlier age include rectal bleeding and stool/bowel habit changes which last for more than a few days."

While CRC gets a great deal of attention, many diseases and conditions of the digestive system - including irritable bowel syndrome, diverticulitis, GERD (acid reflux) and Crohn`s disease - can be chronic and are difficult to diagnose and treat, according to Dr. Larry Good, a gastroenterologist affiliated with South Nassau Communities Hospital. [With many of these diseases, blood work and colonoscopies all looks normal, so there is an absence of red flags."

Many of the diseases of the digestive system are tied to the foods we eat, and a number of sufferers can reduce their symptoms by restricting their diets, Good said. [Of course no one wants to hear that they can`t eat certain foods, but many times, eliminating acidic things from the diet, such as tomatoes, onions, and red wine, can have an impact," Good said.

There are a number of tests to detect digestive tract ailments. A colonoscopy is the examination of the inside of the colon using a long, flexible, fiber-optic viewing instrument called a colonoscope, according the American Gastroenterological Association. Other testing procedures include upper GI endoscopy, capsule endoscopy, endoscopic retrograde cholangiopancreatography and endoscopic ultrasound.
