[0022] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. Terms such as "upper," "inner," "middle," "left," "right," and "one" used in this specification are for ease of description and are not intended to limit the scope of the present invention. Changes or adjustments to these terms, without substantially altering the technical content, are also considered within the scope of the present invention.
[0023] like Figure 1 As shown, the mother-child pond aquaculture system of the present invention includes an external purification ditch 1, a daughter pond 2, and a mother pond 3. The daughter pond 2 is arranged inside the mother pond 3, and the external purification ditch 1 is arranged outside the mother pond 3. The external purification ditch 1 provides purified water to the daughter pond 2 and the mother pond 3 respectively. In specific implementation, the daughter pond 2 can be a small pond formed by enclosing the mother pond 3 and can be arranged in a corner of the mother pond 3. The remaining part of the enclosing ditch is the mother pond 3. This makes it convenient for the external purification ditch 1 to provide water to the daughter pond 2 and the mother pond 3 at the same time. The external purification ditch 1 is connected to the daughter pond 2 and the mother pond 3 respectively through the first communicating vessel 5, so that the water source of the external purification ditch 1 enters the daughter pond 2 and the mother pond 3 respectively from the first communicating vessel 5. The daughter pond 2 and the mother pond 3 are connected to each other through the second communicating vessel 9, so that the water between the daughter pond 2 and the mother pond 3 flows through the second communicating vessel 9. A fishing device 4 is provided between the daughter pond 2 and the mother pond 3. The fishing device 4 is detachably connected so as to be lowered during the fishing season and put away during the non-fishing season. In order to facilitate installation and removal, the fishing device 4 can be detachably connected to the second communicating vessel 9 during the specific implementation.
[0024] In order to facilitate the control of the inflow and outflow of water, the first communicating vessel 5 includes a first communicating pipe 51 and a first valve 52. Figure 2As shown, a first connecting pipe 5 is buried in the pond base between the external purification ditch 1 and the daughter pond 2. The first connecting pipe 5 is also buried in the pond base between the external purification ditch 1 and the parent pond 3, connecting the external purification ditch 1 with the daughter pond 2 and the parent pond 3. A first valve 52 is installed on the pipeline of the first connecting pipe 51. When the first connecting pipe 51 needs to enter or exit the water source, the first valve 52 is opened; when the first connecting pipe 51 does not need to enter or exit the water source, the first valve 52 is closed.
[0025] like Figure 3 As shown, the second communicating vessel 9 includes a second communicating pipe 91 and a second valve 92. The second communicating pipe 91 is buried in the pond base between the daughter pond 2 and the parent pond 3, connecting the daughter pond 2 and the parent pond 3. The second valve 92 is set on the pipeline of the second communicating pipe 91 to control the flow of water between the daughter pond 2 and the parent pond 3. When water flow between the daughter pond 2 and the parent pond 3 is required, the second valve 92 is opened; when water flow between the daughter pond 2 and the parent pond 3 is not required, the second valve 92 is closed. The end of the second communicating pipe 91 facing the daughter pond 2 is provided with an extension pipe body 93, that is, the extension pipe body 93 is located in the daughter pond 2.
[0026] In order to better catch aquatic products, the fishing device 4 includes a fishing body 41 and a net bag 42. Figure 4 As shown. The fishing body 41 is funnel-shaped, with a wide end and a narrow end. The opening of the net bag 2 is fixedly connected to the wide end of the fishing body 41, so that aquatic products enter from the wide end and run out from the narrow end and fall into the net bag 2. The fishing device 4 is not placed during daily breeding, and is only lowered when fishing is needed. When fishing is carried out, the wide end of the fishing body 41 is put on the extension tube body 93 of the second connecting pipe 91, so that the inlet (wide end) of the fishing body 41 is connected to the mother pond 3, and the outlet (narrow end) of the fishing body 41 is connected to the daughter pond 2, and the net bag 42 is placed in the daughter pond 2. In order to facilitate the installation of the fishing device 4, a mounting handle is provided on the fishing body 41, and the mounting handle can be hinged to both sides of the wide end of the fishing body 41. During installation, a worker grasps the installation handle, aligns the wide end of the fishing body 41 with the extension tube 93 of the second connecting tube 91, and then pulls firmly to insert the fishing body 41 into the extension tube 93. The inlet (wide end) of the fishing body 41 must match the diameter of the extension tube 93 to ensure a smooth fit. To extend the service life of the fishing body 41, the fishing body 41 is made of stainless steel.
[0027] In order to facilitate phased planning and management of aquaculture, the height of the pond base 6 of the daughter pond is lower than the pond base 7 of the mother pond. In the early stage of aquaculture, aquatic seedlings are placed in the daughter pond 2 for aquaculture, which is conducive to refined feeding management. When the seedlings are grown to a certain extent and need to be aquacultured in the entire pond, water can be added to cover the daughter pond 2, so that the daughter pond 2 and the mother pond 3 are connected to form a large-scale aquaculture space. Compared with aquaculture in a small water body alone, a larger water surface is more stable and more conducive to resisting the changes in water level and water quality caused by typhoons and rainstorms. It is not easily affected by bad weather, and the water body is stable, which is conducive to the growth of aquatic products. At the same time, the slightly lower pond base 6 of the daughter pond can increase the shallow water area for aquaculture shrimps, increase the shrimp molting area, and thus help improve the aquaculture efficiency of aquatic products.
[0028] In order to purify the water source, aquatic plants 8 are planted in the external purification ditch 1. The pollutants are removed through the absorption of pollutants by the aquatic plants 8, the degradation of organic matter by the microbial film formed by the roots of the aquatic plants 8, and the absorption of nutrients by the plants themselves, forming a natural purification system to ensure the quality of the aquaculture water source.
[0029] Taking the cultivation of Australian freshwater lobster as an example, in the early stages of cultivation, the first valve 52 of the first connecting vessel 5 between the daughter pond 2 and the external purification ditch 1 is opened. Due to the high water level in the external purification ditch 1, the water is forced through the first connecting vessel 5 into the daughter pond 2 by the gravity of the water body. After the water level in the daughter pond 2 reaches the cultivation requirement, the first valve 52 is closed, and then the Australian freshwater lobster fry are released into the daughter pond 2. The daughter pond 2 is small in area, which facilitates refined management. After the Australian freshwater lobsters are cultivated to 5-8 cm in diameter, the fry have strong survival ability. At this time, the first valve 52 of the first connecting vessel 5 between the mother pond 3 and the external purification ditch 1 is opened. Water is poured into the mother pond 3 through the gravity difference of the water body in the external purification ditch 1. Water is continued to be added until it covers the daughter pond 2. When the water body reaches the required depth, the second valve 92 of the second connecting vessel 9 between the daughter pond 2 and the mother pond 3 is opened, and the Australian freshwater lobsters are cultivated in the entire pond.
[0030] When the Australian freshwater lobsters have reached maturity, the fishing device 4 is installed on the extension tube 93 of the second communicating vessel 9. The water level of the mother pond 3 is lowered, so that the water level of the mother pond 3 is lower than that of the daughter pond 2. This creates a liquid level difference between the two. Australian freshwater lobsters have a habit of swimming against the current, so they swim against the current to the fishing body 41 of the fishing device 4 and fall into the net bag 42, thus achieving the lobster capture. Compared with traditional ground trap fishing, this utility model utilizes the liquid level difference to increase the capture rate and reduce the difficulty of fishing.
[0031] The utility model, by setting up a mother-and-child pond, is conducive to the refined management of small-area daughter ponds in the early stage of aquaculture, and large-area aquaculture in the middle and late stages. It uses small ponds for seedling cultivation and large ponds for aquaculture, reduces the impact of bad weather on water quality, and makes the water body more stable. The aquaculture method of the mother-and-child pond also increases the pond base area within the pond, increases the molting area of shrimp aquaculture, is conducive to promoting the growth of shrimp aquatic products, and is also conducive to the construction of winter sheds in the daughter ponds. In view of the countercurrent characteristics of aquatic products, the liquid level difference can also be reasonably utilized to set up a fishing device to increase the fishing rate, reduce the difficulty of fishing, and meet the needs of rapid pond sales.
[0032] The mother-child pond breeding system of the present invention is suitable for breeding aquatic products including but not limited to Australian freshwater lobsters, crayfish, crabs, etc. All aquatic products that are traditionally caught using ground traps and have countercurrent properties can be bred and caught using the present invention.
[0033] The implementation methods of the present invention are not limited to this. According to the above content of the present invention, by utilizing common technical knowledge and customary means in this field, without departing from the above basic technical ideas of the present invention, the present invention can also make other various forms of modification, replacement or combination, all of which fall within the scope of protection of the present invention.
