Description

Technical Field

[0001] The utility model relates to the field of crayfish breeding, in particular to a breeding and feeding device for crayfish in rice fields. Background Art

[0002] Crayfish is a freshwater crustacean with a wide range of food intake and strong adaptability to the environment. It has become an important aquaculture species. There are many ways to farm crayfish. The rice field shrimp farming model is based on the symbiotic and mutually beneficial characteristics of rice and crayfish, and makes full use of the ecological environment and resources.

[0003] To achieve high yield of crayfish farming in rice fields, feeding is an extremely important task in crayfish farming. At the same time, the control of feeding amount during feeding also has a great impact on the yield of crayfish: if the feeding amount is too little, the crayfish will grow slowly and cannibalize each other; if the feeding amount is too much, not only will the feed be wasted, but the excess feed will easily cause the water quality to deteriorate in a short period of time, causing the crayfish to be invaded by unnecessary diseases, pests and hypoxia.

[0004] The existing paddy field crayfish breeding and feeding device, such as application number: CN201721126699.1, is a feeding device for feeding crayfish in paddy fields, including a strip-shaped net bag, which is woven from flexible ropes; it also includes a stand for setting up the strip net bag, the stand includes a vertical pole, a support plate is fixed on the vertical pole, and the support plate protrudes outward relative to the side of the vertical pole; the strip net bag is also provided with a feeding net opening. And application number: CN202222713235.8 A rice field crayfish breeding feeding net, comprising a first support rod, a second support rod is slidably installed on one side of the first support rod through a snap-fit ​​mechanism, a third support rod is slidably installed on one side of the second support rod through a snap-fit ​​mechanism, a buoyancy ring is provided on one side of the third support rod, a net bag is sleeved at the bottom end of the buoyancy ring, a clamp is snap-fitted and installed on the outside of the sleeve of the buoyancy ring and the net bag, and a ridge ring is provided on the top of the buoyancy ring, and the buoyancy ring and the ridge ring are both circular. The utility model is provided with a ridge ring, a net bag, a rubber band ring and a first support rod, so that the buoyancy ring is pulled to the shore, which is convenient for taking out the residual material and avoiding continuous decomposition in the water, and the rubber band ring is tied to the bottom of the net bag, so that some lobsters can be taken out to observe the growth status when the net is collected, and the rubber band ring is removed, so that the lobsters can swim away from the bottom of the net bag to avoid damage to the lobsters.
