Abstract
Description
Technical Field
[0001] The utility model provides a hanging cage for cultivating fry of ring-shaped snails in ponds, reservoirs, canals or fish ditches in rice fields, and belongs to the field of freshwater snail breeding facilities in aquaculture. Background Art
[0002] All species of the genus Anilophaga are commonly known as snails, stone snails, and field snails. They are the core raw materials of Liuzhou snail noodles in Guangxi. They belong to the phylum Mollusca, class Gastropoda, subclass Prosobranchia, and are widely distributed in freshwater lakes, reservoirs, rice fields, ponds and ditches across my country. Because they feed on organic debris such as algae, leftover bait and feces, they play an important role in energy transport and water purification in aquatic environments. In addition, studies have found that their meat is tender, delicious, nutritious, and has therapeutic effects such as clearing heat and thirst, and improving eyesight, making them one of people's favorite aquatic products, especially southerners who regard them as a delicacy at banquets. In recent years, with the rise of the tertiary industry of snail noodles in Guangxi, its annual output value has exceeded 70 billion yuan, and the annual consumption of snails exceeds 20,000 tons, which has greatly promoted the development of my country's snail farming industry.
[0003] At present, the most common species cultivated in my country are the ring-shaped snail and the round pond snail, which are mainly cultivated in rice fields and ponds. However, both have the following problems that need to be solved:
[0004] ① Rice Field Snail Culture: In rice field snail culture, birds often threaten the snails. While pest control is carried out before stocking, incomplete pest control or loose sealing of water inlets can lead to the infiltration of feral fish and golden apple snails into rice fields, stealing their ecological niches and even harming the snails. Currently, neither biological nor chemical control methods can eliminate these feral fish and golden apple snails without harming the snails. Their high reproductive capacity makes manual control ineffective, with minimal results. These pests reduce snail production and increase management costs, and no effective control measures exist.
[0005] In addition, during the snail farming process, machinery cannot enter the fields to operate, and rice planting and harvesting can only rely on manual labor; the shells of dead snails remain in the fields and will cut farmers' feet; there is no snail catching machinery, so snails can only be picked up or raked manually. All of the above increase the cost of snail farming.
[0006] ② Pond snail farming technology: purifies water quality and facilitates harvesting. The pond snail farming model often mixes fish, shrimp and other aquatic species to achieve a three-dimensional farming effect of raising fish and shrimp in the water and raising snails on the bottom of the water. Its disadvantages are also obvious:
[0007] (1) Become a supplementary bait and a by-product. Since fish and shrimps will prey on snails, farmers often pay more attention to fish and shrimps with higher economic value and ignore snails, making it impossible to guarantee the production of snails, and thus they become a by-product.
[0008] (2) Fishing is limited and production is underestimated. Snails can only be caught when the ponds are cleared for fish and shrimp. If fish and shrimp are only caught once a year, snails can only be caught once, which leads to an underestimation of snail production.
[0009] Therefore, how to design a hanging cage for cultivating seedlings of conch shells in ponds has become a technical problem to be solved by those skilled in the art. Summary of the Invention
[0010] In view of the deficiencies of the above-mentioned prior art, the technical problem to be solved by the present invention is: to provide a hanging cage for cultivating pond seedlings of ring-edged snails, which solves the problems that the traditional hanging nets for breeding are exposed to the open air and cannot protect the snails from being harmed by birds; the hanging nets are made of nylon material, which is relatively soft and the mesh is easily clogged, resulting in obstruction of water exchange inside and outside the net; the snails in the hanging nets can only scrape the bait at the bottom or the attachments on the four sides.
[0011] In order to solve the above technical problems, the present invention adopts the following technical solutions:
[0012] The invention discloses a hanging cage for cultivating seedlings of ring-edge snails in ponds, comprising an upper cover, a lower shell, an attachment plate and a buoyancy ball bracket. The overall design of the hanging cage is an elliptical barrel shape, and the buoyancy ball brackets are arranged on both sides of the lower shell. The hanging cage can float on the water surface by adding the buoyancy balls; an attachment plate is arranged in the cage to increase the attachment space in the cage; the attachment plate is clamped in the slots on both sides and is connected by connecting strips on both sides to reinforce the attachment plate; rectangular lower shell water holes are evenly distributed around the lower shell to facilitate water exchange inside and outside the cage during the snail cultivation process; at the same time, a lower shell reinforcement strip is provided to reinforce the lower shell shell; similarly, upper cover water holes are also evenly distributed around the upper cover, and an upper cover reinforcement strip is added; an upper cover handle and a lower shell handle are respectively provided at corresponding positions on the edges of the two end sections of the upper cover and the lower shell; at the same time, an upper cover positioning column and a lower shell fixing hole are respectively provided at corresponding positions on the edges in the middle of the upper cover and the lower shell.
[0013] Preferably, all materials used to make the cage are plastic, and the buoyancy ball is plastic.
[0014] Preferably, the diameter of the water-permeable hole in the upper cover and the water-permeable hole in the lower shell is 2.7 mm.
[0015] Beneficial effects
[0016] Among the existing technologies used in snail farming, the one that is relatively similar to the present invention is the hanging net snail farming technology. Compared with this technology, the present invention has the following advantages:
[0017] 1. The utility model adopts a movable cage cover design, which helps to prevent birds from preying on snails in the cage and solves the problem that the hanging net is exposed to the open air and cannot protect the snails from being harmed by birds.
[0018] 2. The utility model is made of plastic, the mesh is not easy to be clogged, and the water permeability is strong, which solves the problem that the hanging net is made of nylon material, which is relatively soft and the mesh is easily clogged, resulting in obstruction of water exchange inside and outside the net.
[0019] 3. The utility model is designed with an attachment plate inside the cage, which increases the attachment area of water debris and microorganisms, increases the feeding place of snails in the cage, and solves the problem that the snails in the hanging net can only scrape the bait at the bottom or the attachments on the four sides.
