Description

Technical Field

[0001] The invention relates to the technical field of marine shellfish breeding, and in particular to a method for cultivating young sea clams. Background Art

[0002] Coelomactra antiquata belongs to the phylum Mollusca, class Bivalvia, order Cercophoridae, and family Cercophoridae. It is commonly known as "royal concubine clam" or "sea clam". Coelomactra antiquata mainly inhabits sandy beaches about 20 meters deep from the intertidal zone to the subtidal zone. It is a shallow-sea buried bivalve. Due to its tender meat, delicious taste, and rich in high-quality protein, vitamins and minerals, Coelomactra antiquata has become an ideal choice for many food lovers and those who pursue healthy eating. It has significant economic potential and is highly favored by the market.

[0003] As people's demand for healthy diets continues to increase, the market prospects for sashimi are becoming increasingly broad. However, the accompanying overfishing problem is becoming increasingly serious, which has caused obvious damage to sashimi resources, and the resources in many habitats are close to exhaustion. Overfishing not only disrupts the local ecological balance, but also threatens the long-term survival of species, leading to the degradation of ecosystems and the reduction of biodiversity. Therefore, how to protect existing resources and supplement wild resources through sustainable breeding methods has become a key issue that needs to be solved urgently.

[0004] Traditional artificial seedling raising methods are usually carried out in indoor seedling ponds or cement pools. However, due to the high requirements of water quality and bottom environment for the scallops, the survival rate of juvenile spat is generally low, and the yield of seedling raising is also unstable. The sensitivity of the scallops to the cleanliness of the water, oxygen content and benthic conditions makes it difficult for traditional seedling raising methods to effectively meet its growth needs. Therefore, the development of more advanced seedling raising technology is the key to improving the survival rate of seedlings and optimizing aquaculture benefits. Summary of the invention

[0005] In view of this, the present invention aims at the deficiencies of the prior art and proposes a method for cultivating young sea clams, aiming to solve at least one of the problems raised by the above background technology.

[0006] The present invention provides a method for cultivating young sea clams, comprising the following steps:

[0007] S1: Open the valve of the lower water outlet of the container to drain the water in the breeding pond to the sand layer, and close the valve of the lower water outlet after completion;

[0008] S2: Open the valve of the lower water inlet, add water from the breeding pond to the upper water outlet, and open the valve of the upper water outlet when the water level reaches the upper water outlet;

[0009] S3: Close the valve of the upper water outlet, and then open the valve of the lower water outlet;

[0010] S4: Close the valves of the lower water inlet and the lower water outlet, then open the valve of the upper water outlet to add water to the position of the upper water outlet;

[0011] S5: Close the valve of the upper water inlet;

[0012] Steps S1 to S5 constitute a complete cycle.

[0013] In some embodiments, the sand layer is laid on top of the filler layer.

[0014] In some embodiments, the upper water inlet and the lower water inlet are both arranged at the left end of the container, and the upper water outlet and the lower water outlet are both arranged at the right end of the container.

[0015] In some embodiments, the upper water inlet is communicated with the lower water inlet.

[0016] In some embodiments, step S1 takes 15 minutes.

[0017] In some embodiments, step S2 takes 30 minutes.

[0018] In some embodiments, step S3 takes 5 minutes.

[0019] In some embodiments, step S4 takes 10 minutes.

[0020] In some embodiments, after step S5 is completed, the system is left to stand for 11 hours, and the entire system performs a complete cycle every 12 hours.

[0021] In some embodiments, the filler layer thickness is 5 cm, the sand layer thickness is 10 cm, and the water depth is 50 cm;

[0022] The DO of the water is 6-7.5 mg / L; the PH of the water is 8.0-8.2; the temperature of the water is 15-26℃; the salinity of the water is 24-32.

[0023] Compared with the prior art, the beneficial effect of the present invention is that by optimizing the hydrodynamic conditions, such as enhancing the fluidity and shear force of the sand layer, it is helpful to simulate the natural growth environment of the Chinese tongue, thereby reducing the occurrence of diseases and significantly improving the survival rate of young shellfish. The introduction of an automated equipment control system can accurately adjust the flow rate and direction of the water flow according to actual breeding needs to ensure the flexibility and adaptability of the system. The application of automated facilities greatly reduces the need for manual intervention, especially in daily maintenance work such as water quality monitoring and cleaning. This not only reduces labor costs, but also makes the breeding process more efficient, stable and sustainable. The breeding system adopts a water flow design that flows in and out from top to bottom, realizes the continuous recycling of water, and reduces the waste of water resources. At the same time, by adjusting the water flow speed and direction, the concentration of pollutants in the water body can be effectively controlled to reduce the impact on the surrounding environment. The design of the system has certain flexibility and can be adjusted according to different breeding scales. Whether it is a small-scale family farm or a large-scale commercial farm, a suitable solution can be customized according to actual conditions.

[0024] The foregoing general description and the following detailed description are exemplary and explanatory only and are not restrictive of the present disclosure.

For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0033] As described in the background technology, Coelomactra antiquata belongs to the phylum Mollusca, class Bivalvia, order Cercophoridae, and family Clamidae, commonly known as "royal concubine mussel" or "sea mussel". Coelomactra antiquata mainly inhabits the sandy beach about 20 meters deep from the intertidal zone to the subtidal zone, and is a shallow sea buried bivalve. Due to its tender meat, delicious taste, and rich in high-quality protein, vitamins and minerals, Coelomactra antiquata has become an ideal choice for many food lovers and those who pursue healthy eating, and has significant economic potential and is favored by the market.

[0034] As people's demand for healthy diets continues to increase, the market prospects for sashimi are becoming increasingly broad. However, the accompanying overfishing problem is becoming increasingly serious, which has caused obvious damage to sashimi resources, and the resources in many habitats are close to exhaustion. Overfishing not only disrupts the local ecological balance, but also threatens the long-term survival of species, leading to the degradation of ecosystems and the reduction of biodiversity. Therefore, how to protect existing resources and supplement wild resources through sustainable breeding methods has become a key issue that needs to be solved urgently.

[0035] Traditional artificial seedling raising methods are usually carried out in indoor seedling ponds or cement pools. However, due to the high requirements of water quality and bottom environment for the scallops, the survival rate of juvenile spat is generally low, and the yield of seedling raising is also unstable. The sensitivity of the scallops to the cleanliness of the water, oxygen content and benthic conditions makes it difficult for traditional seedling raising methods to effectively meet its growth needs. Therefore, the development of more advanced seedling raising technology is the key to improving the survival rate of seedlings and optimizing aquaculture benefits.

[0036] To improve the above problems, a method for cultivating young sea clams proposed in this application helps to simulate the natural growth environment of the sea clams by optimizing hydrodynamic conditions, such as enhancing the fluidity and shear force of the sand layer, thereby reducing the occurrence of diseases and significantly improving the survival rate of young clams. The introduction of an automated equipment control system can accurately adjust the flow rate and direction of the water flow according to actual aquaculture needs to ensure the flexibility and adaptability of the system. The application of automated facilities greatly reduces the need for manual intervention, especially in daily maintenance work such as water quality monitoring and cleaning. This not only reduces labor costs, but also makes the aquaculture process more efficient, stable and sustainable. The aquaculture system adopts a water flow design that flows in and out from top to bottom, realizes the continuous recycling of water, and reduces the waste of water resources. At the same time, by adjusting the water flow speed and direction, the concentration of pollutants in the water body can be effectively controlled to reduce the impact on the surrounding environment. The design of the system has certain flexibility and can be adjusted according to different aquaculture scales. Whether it is a small-scale family farm or a large-scale commercial farm, a suitable solution can be customized according to actual conditions.

[0037] See also Figure 1-2 As shown, a method for cultivating young sea clams according to an embodiment of the present application comprises the following steps:

[0038] S1: Open the valve of the lower water outlet of the container to drain the water in the breeding pond to the sand layer, and then close the valve of the lower water outlet after completion;

[0039] S2: Open the valve of the lower water inlet, add water from the breeding pond to the upper water outlet, and open the valve of the upper water outlet when the water level reaches the upper water outlet;

[0040] S3: Close the valve of the upper water outlet, and then open the valve of the lower water outlet;

[0041] S4: Close the valves of the lower water inlet and the lower water outlet, then open the valve of the upper water outlet to add water to the position of the upper water outlet;

[0042] S5: Close the valve of the upper water inlet;

[0043] Steps S1 to S5 constitute a complete cycle.

[0044] It should be understood that the automated system can accurately control water quality and water level according to preset parameters, avoiding errors caused by human operation. It can monitor changes in the aquaculture environment in real time, adjust valve switches in time, and ensure that aquaculture conditions are always kept in the best state. Automation reduces the need for manual operation, reduces labor intensity, and reduces errors caused by human factors. The entire system performs a complete cycle every 12 hours, which means that the water quality can be updated frequently without the need for constant manual monitoring and adjustment. Each step has a fixed time requirement, making the operation more standardized and efficient, and reducing unnecessary waiting and delays. Regularly circulating water quality helps maintain the stability of key parameters such as dissolved oxygen, temperature, and pH in the water, providing optimal growth conditions for young sea clams. Good water quality and a stable environment help reduce the growth pressure of young clams, promote their healthy growth, and increase survival rates. By accurately controlling the amount and quality of water, the waste of water resources is reduced and the efficiency of resource use is improved. The use of chemicals is reduced, the impact on the environment is reduced, and it meets the requirements of sustainable development. Regularly changing the water quality can effectively remove pathogens and harmful substances in the water and reduce the occurrence of diseases. A stable breeding environment and high-quality water quality help improve the immunity of young sea clams, making them more resistant to disease. The use of automated systems reduces labor costs and improves breeding efficiency, thereby reducing overall breeding costs. By optimizing breeding conditions, the yield and quality of young sea clams can be increased, increasing economic benefits. This method of breeding young sea clams not only improves the efficiency and stability of breeding, but also helps protect the environment, reduce the risk of disease, and ultimately achieve improved economic benefits.

[0045] The valves can be:

[0046] Ball valve, which can be opened and closed by rotating 90°, has the advantages of small fluid resistance, simple structure, small size and light weight. In the process of cultivating young clams, ball valves can be used in occasions that require rapid opening and closing, such as emergency water flow cut-off or water flow regulation.

[0047] Gate valves open or cut off the flow of media in the pipeline by lifting the gate plate. They have good fluid control characteristics and low pressure loss. In the inlet and outlet pipes of the aquaculture pond, gate valves can be used to control the flow of water to ensure the stability of the aquaculture environment.

[0048] Butterfly valve is a simple regulating valve consisting of a short tube and a disc. It can open or close the water flow by rotating the disc and has good flow control characteristics. In the process of cultivating young clams, butterfly valves can be used in occasions where water flow needs to be adjusted frequently, such as adjusting the water level or water quality of the breeding pond.

[0049] Check valve, a check valve is an automatic valve that prevents the backflow of the medium. When the system pressure exceeds the set value, it automatically opens to release the excess pressure. In the aquaculture system, the check valve can be used to prevent the reverse flow of water and protect the water pump and other equipment from damage.

[0050] Safety valve, a valve that automatically opens to release excess pressure when the system pressure exceeds the set value. In the process of cultivating young clams, the safety valve can be used to maintain the pressure stability in the aquaculture system to prevent equipment damage or deterioration of the aquaculture environment due to excessive pressure.

[0051] Solenoid valve is an automatic valve that drives the valve to open and close through the magnetic field generated by the electromagnetic coil. It has the advantages of fast response speed and high precision. In the sea clam juvenile cultivation system with a high degree of automation, the solenoid valve can be used in conjunction with the automatic control system to achieve precise adjustment of the working conditions.

[0052] In summary, the selection and use of these valves should be determined according to the specific farming environment and needs. For example, in situations where precise control of water flow is required, a solenoid valve may be selected; while in situations where reverse flow of water is required, a check valve may be selected. At the same time, the performance, reliability and compatibility of the valve with the system are also important factors to consider when selecting a valve.

[0053] In some specific embodiments, the sand layer is laid on top of the filler layer.

[0054] In some specific embodiments, the upper water inlet and the lower water inlet are both arranged at the left end of the container, and the upper water outlet and the lower water outlet are both arranged at the right end of the container.

[0055] In some specific embodiments, the upper water inlet is communicated with the lower water inlet.

[0056] In some specific embodiments, step S1 takes 15 minutes.

[0057] In some specific embodiments, step S2 takes 30 minutes.

[0058] In some specific embodiments, step S3 takes 5 minutes.

[0059] In some specific embodiments, step S4 takes 10 minutes.

[0060] In some specific embodiments, the step S5 is left to stand for 11 hours after completion, and the entire system performs a complete cycle every 12 hours.

[0061] In some specific embodiments, the filler layer thickness is 5 cm, the sand layer thickness is 10 cm, and the water depth is 50 cm;

[0062] The DO of the water is 6-7.5 mg / L; the PH of the water is 8.0-8.2; the temperature of the water is 15-26℃; the salinity of the water is 24-32.

[0063] It should be understood that a container is set up for the cultivation of young sea clams, an opening is set at the top of the container, a lower water inlet is set at the bottom of the container, an upper water outlet is set at the right side wall of the top of the container, an upper water inlet is set at the top of the left side wall of the container, and a lower water inlet is set at the bottom of the left side wall of the container. A bracket is set at the bottom of the container, a filler layer is laid on the top of the bracket, a sand layer is laid on the top of the filler layer, and then water is poured into the container. The thickness of the filler layer is 5cm, the thickness of the sand layer is 10cm, and the water depth is 50cm. Water quality DO: 6-7.5mg / L; PH: 8.0-8.2; temperature: 15-26℃; salinity: 24-32. The whole system performs a complete cycle in 12 hours, and uses automated equipment control to accurately adjust different working conditions to ensure that the breeding process is efficient, stable and sustainable.

[0064] The addition of sand layers can improve the fluidity of water flow, making it smoother when passing through the filler layer. This enhanced fluidity helps simulate the hydrodynamic conditions in the natural growth environment of the oyster, thereby providing a living environment closer to nature for the young oysters. The presence of the sand layer increases the shear force of the water flow on the bottom of the culture pond, which helps prevent sediment accumulation at the bottom of the pond and keep the water clean. At the same time, appropriate shear force can also promote the movement of young oysters, which is beneficial to their growth and development. In the natural environment, the oysters usually live on the sandy seabed, so the introduction of sand layers in artificial culture systems can better simulate their natural habitat. This not only helps to improve the survival rate of young oysters, but also promotes their healthy growth. The sand layer can play a certain buffering role and help stabilize key water quality parameters such as pH value and dissolved oxygen content in the water body. This is crucial to maintaining a water quality environment suitable for the growth of the oysters. The design of the sand layer makes the bottom of the culture pond easy to clean and maintain. By regularly replacing or cleaning the sand layer, the accumulated organic matter and harmful substances can be effectively removed to maintain the hygiene of the culture environment. The sand layer provides space for beneficial microorganisms to attach and reproduce. These microorganisms play an important role in decomposing organic matter and purifying water quality. A healthy microbial community is critical to maintaining a good aquaculture ecological balance. The sand layer laid on top of the filler layer can not only simulate the natural habitat of the oysters, improve the survival rate and growth rate of young clams, but also stabilize water quality parameters, reduce the occurrence of diseases, and has environmental friendliness and scientific research value. These benefits work together to make this aquaculture system an efficient and sustainable oyster aquaculture solution. The combination of the filler layer and the sand layer provides a stable ecological environment for the oysters, reduces the impact of external environmental changes on the cultured organisms, and improves the stability and predictability of aquaculture.

[0065] The dissolved oxygen (DO) range is 6-7.5mg / L, which provides sufficient oxygen supply for the tongue, which helps its respiration and metabolic processes. The appropriate dissolved oxygen level can support healthy biological activities and promote the growth and development of young clams. The pH value is maintained between 8.0-8.2, providing a stable acid-base environment for the tongue. This pH range is close to the natural state of seawater, which is conducive to maintaining the balance of chemical substances in the water body and reducing interference with the physiological functions of the tongue. The water temperature is controlled at 15-26℃, which provides an ideal thermal environment for the growth of the tongue. Within this temperature range, the metabolic activity of the tongue is maintained at a moderate level, neither too fast nor too slow, which is conducive to its healthy growth. The salinity is 24-32, which simulates the salt concentration in the natural habitat of the tongue. This salinity level helps to maintain the osmotic pressure balance of the fluid inside and outside the cell and ensure the normal physiological function of the tongue. Suitable water quality conditions and optimized breeding structure will significantly improve the survival rate of young tongue clams. This not only reduces the death loss caused by environmental discomfort, but also improves the breeding efficiency and economic benefits. The optimized design of the filler layer and the sand layer and the appropriate water quality parameters work together to provide a close-to-natural, stable and suitable growth environment for the shishi tongue, thereby promoting its healthy growth and efficient breeding.
