Crayfish breeding method

The first is to create a good lobster growth environment. The lobster is a kind of shell and shell animal. Similar to crabs, it has a pair of particularly developed chelators and has the habit of digging caves. It is usually drilled near the shore by water. The lobsters are afraid of light. When the light is weak or dark, they climb out of the cave. When the light is strong, they sink into the water or hide in the cave. According to the lobster's habits, a 50-cm-high anti-escape net can be added to the river pond to prevent the lobster from fleeing. At the same time, Hetang simulates the ecological environment of lobster under natural conditions, and 10-15% of aquatic plants and concealed plants are planted under the shallow side of the pond to create a habitat for lobsters and shelling, reducing mutual killing.

The impact of water quality on lobster production cannot be ignored either. The water quality directly affects the healthy growth and development of the lobster. During the breeding process, the ph value of the pool water is maintained at 7.5-8.5, the transparency is 30-40 cm, and new water is often added, and the quicklime solution is regularly splashed and conditioned. Water quality to prevent the occurrence of diseases and shelling.

The second is to properly feed the feed. Lobsters will kill each other when they are hungry and have insufficient food. Therefore, the amount of feed must be sufficient. Lobster feed is animal and plant feed. Vegetable feed is wheat, aquatic grass, rapeseed cake, etc. Animal feedstuffs are miscellaneous fish, miscellaneous meats and livestock viscera. Normally, the feeding time, feeding amount and feeding method are determined according to the habit of lobsters buzzing and the density of shrimp in the pond. Otherwise, it will increase the cost of feed and reduce the breeding efficiency.

The third is scientific fishing. In the lobster culture process, juvenile shrimps can grow to commercial specifications within 60-90 days under appropriate temperature and feed. The seedlings were released in March, and the arrests began in June and sold large and small. Since catching large and small, catching and rotating in rounds, it can increase the rate of catch-up, sell a good price, and achieve high-yield and high-efficiency.

Hospital Bed is mainly designed for patient and used in hospital, hospital bed is much better with technology development, humanized design.

Now more and more people pay attention to Electric Medical Bed which is used in modern hospital as auxiliary medical equipment, electric Icu Bed has easily operation,  electric intelligent operation makes patient feeling much more comfortable, intelligent  and accurate position change also can be achieved, reducing nurses` labor intensity.
