In order to prevent the crabs from escaping, the anti-escape facilities are built 0.3 to 0.5 meters away from the pool. Anti-escape facilities for crab ponds include: 1, agricultural plastic film fence The anti-fence walls of crab ponds are 0.5 to 0.7 meters high (1 year old crab ponds may be slightly lower), and 0.15 meters buried in the soil. The escape wall is slightly tilted to the inside of the tank at an angle of 60 degrees with its inside smooth and without support. The corner of the escape prevention wall is rounded. The placement method is: first take the stake as the pillar, take the lead wire or the plastic rope as the skeleton, fold the double-layer film, press the two lower ends into the mud and put it in 0.1~0.15 meters, and put the upper end on the lead wire or plastic rope. Tight and straight. This method is cheap, the device is convenient, and it is not resistant to strong winds. It needs to be repaired and replaced in time. This type of anti-escape equipment is mainly used for crab or paddy crabs. 2, calcium plastic plate, aluminum skin fence On the pool bowl, a 0.8-meter-high calcium plastic plate or aluminum skin is embedded in the soil and compacted by 20 cm. The tapped steel bar or wood column is used as a pile, and the plate is perforated and fixed on the pile. This method has the advantages of light weight, convenient transportation and installation, low construction cost, and good anti-escape effect. The general service life is 3 to 4 years. This anti-escape facility is mainly used for crab breeding. In addition, in order to prevent frogs, ducks, and other predators from jumping into the crab pool, a polyethylene mesh (4 mesh/cm2) shall be used around the pond. The bottom of the net shall be buried within 10 centimeters of the soil and the net shall be 1 meter high. Frog net, anti-frog network and anti-escape wall interval of 0.5 to 1 meters. Organic Inulin Powder is a natural food source of prebiotic soluble fibers. Inulin is a soluble fiber naturally found in many fruits and vegetables like bananas, asparagus, garlic, onions, and more. Our inulin is extracted from the Jerusalem artichoke rhizome. We extracted the inulin by water extraction, ion exchange, membrane filtration, and spray drying, and other processes.
Inulin has many health benefits. It can increase calcium absorption and possibly magnesium absorption while promoting the growth of beneficial intestinal bacteria.
