Abstract
Description
Technical Field
[0001] This utility model relates to the field of aquaculture technology, and in particular to an artificial breeding device for river clams. Background Technology
[0002] Also known as clam, sand clam, golden clam, and yellow clam, it belongs to the class Lamellibranchia, order Eulamellibranchia, family Corbiculidae, and genus Corbicula. The shell is medium-sized, with its height and length approximately equal, and its shape is roughly triangular. The shell surface is glossy and ranges in color from yellow, yellowish-green, dark brown, to jet black; the shell color is related to its habitat and age. River clams are widely distributed in rivers, lakes, and ditches throughout my country, especially in rivers where fresh and saltwater meet at the confluence of fresh and saltwater, where the bottom is mostly sandy, sandy-muddy, or muddy. The clam meat is edible and can be made into dried clams or canned goods; the shells can be used as raw material for lime production and for making handicrafts. However, in recent years, the deterioration of lake water resources has led to a sharp decline in the survival rate of river clams, making the adoption of more efficient breeding methods extremely urgent.
[0003] Traditional river clam breeding is carried out using breeding ponds. A month before the breeding season, the parent river clams are transferred to the breeding ponds, and the ponds are filled with nylon nets to prevent the offspring from being bred and kept in the breeding ponds. Nutrient mud is added after the parent clams are removed. However, the traditional river clam breeding process is cumbersome, and the transfer of parent clams can affect the survival rate of offspring. Therefore, it is very important to design a low-cost, easy-to-manage, and reusable river clam breeding device. Utility Model Content
[0004] The purpose of this invention is to provide an artificial breeding device for river clams, thereby solving the problem of improving the breeding efficiency of artificial river clams.
[0005] The technical solution adopted by this utility model to solve its technical problem is: an artificial breeding device for river clams, including a breeding suspended net box structure, a seedling cultivation net box structure connected to the breeding suspended net box structure, and external components located outside the breeding suspended net box structure and the seedling cultivation net box structure. The seedling cultivation net box structure includes an upper suspended frame structure and an upper protective net body located on the outer periphery of the upper suspended frame structure. The seedling cultivation net box structure includes a seedling net frame, a lower protective net body located on the outer periphery of the seedling net frame, and a cultivation bed structure located at the lower part of the inner bottom surface of the seedling net frame.

[0007] A transition device structure for offspring to fall is provided between the seedling net frame and the hanging frame.
[0008] The offspring falling transition device structure includes a transition frame, an assembly slow-fall plate structure in the middle of the transition frame, and a bottom sludge flow port on the outside of the transition frame. The bottom sludge flow port is divided into two layers: an outer layer with an outer layer flow baffle assembly and an inner layer with a filter body. The filter body is at the same height as the outer layer flow baffle assembly.
[0009] The cultivation bed structure includes a bottom connecting plate in the seedling net frame and a cultivation base layer located on the upper part of the bottom connecting plate.
[0010] The aquaculture substrate includes a nutrient mud layer and a sand and gravel layer.
[0011] The hoisting platform structure includes a hoisting cover and multiple sets of hoisting connection holes located in the hoisting cover.
[0012] The beneficial effects of this invention are as follows: The device is flexibly disassembled and can be automatically adjusted according to environmental conditions. The main body of the equipment is a pole-and-wire type net cage suspension cultivation device, which is fixed with wooden stakes at both ends according to the water flow direction. Compared with traditional breeding methods, it eliminates the need to remove the clam parent stock and add nutrient mud, making the process simpler, more efficient, and reusable.

[0024] The cultivation bed structure includes a bottom connecting plate 10 in the seedling net frame 3 and a cultivation base layer located on the upper part of the bottom connecting plate. The cultivation base layer includes a nutrient mud layer 11 and a sand and gravel layer 12.
[0025] Example 2, as Figure 4-5 As shown, based on Example 1, in order to facilitate the seedlings falling into the seedling cultivation net box structure, a transition device structure for the offspring to fall is set between the seedling net frame 3 and the hanging frame 1.
[0026] The offspring falling transition device structure includes a transition frame 13, an assembly slow-fall plate structure in the middle of the transition frame, and a bottom sludge flow port 14 on the outside of the transition frame. The bottom sludge flow port is divided into two layers: an outer layer with an outer layer flow baffle group 15 and an inner layer with a filter body 16. The filter body and the outer layer flow baffle group have the same height.

[0028] This device is flexibly disassembled and can be automatically adjusted according to environmental conditions. The main body of the equipment is a pole-and-wire type suspended net cage culture device, which is fixed at both ends with wooden stakes according to the water flow direction. The wooden stakes are connected by nylon or PE wire. Double-layer detachable net cages are used to breed river clams. The two layers of net cages are fixed with slots or buckles for easy disassembly. The structure of the breeding suspended net cage, the bottom of which is open and the top of the seedling cultivation net cage are open, so that the offspring can fall into the lower net cage. Floats are used to suspend the net cages on the suspended culture device, which can better adapt to changes in water flow. The upper layer is used to place the river clam parent stock. A layer of plastic tarpaulin is laid at the bottom of the seedling cultivation net cage structure. The four sides of the net cage are fixed with ethylene netting with a mesh size of 1-2cm. Nutrient mud and gravel are added to the bottom of the seedling cultivation net cage structure, with a thickness of about 2cm. The offspring of the river clam parent stock fall directly into the lower nutrient mud for further cultivation. After the upper net cage is disassembled, the parent stock is poured into the pond for further cultivation. Compared with traditional breeding methods, there is no need to remove the parent clam species and add nutrient mud. The process is simpler and more efficient, and the equipment can be reused. The new breeding device not only reduces the cost of clam farming, but also improves the yield and quality of clam.
