The terms "first," "second," etc., in the specification, claims, or foregoing drawings of this application are used to distinguish different objects, not to describe a particular order.

[0020] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0021] This utility model embodiment provides a constant-temperature indoor incubator for California bass fry, such as... Figure 1-4 As shown, the California bass constant-temperature indoor incubator for fry includes: an incubation box 1 that can be placed indoors for incubating California bass fry, with a mesh plate 2 horizontally arranged inside the incubation box 1, and a mesh box 3 for placing fish eggs on the mesh plate 2; a constant-temperature heating rod 4 installed inside the incubation box 1 for heating the water; a base box 5 fixedly installed at the bottom of the incubation box 1, with an oxygen pump 6 installed inside the base box 5, the outlet of the oxygen pump 6 supplying oxygen to the water in the incubation box 1 through a connected air pipe 7, and an aeration head 8 installed at the outlet of the air pipe 7; and a mounting frame 9 installed on the incubation box 1, with a filtration mechanism for filtering the incubation water installed on the mounting frame 9 and the base box 5.

[0022] In this embodiment, the incubation box 1, as the main structure of the entire incubator, is placed in a specific indoor location, providing a relatively closed and stable spatial environment for the hatching of California bass fry. This avoids direct interference from the external environment, isolates predators, impurities, and some microorganisms from the natural environment, and allows the hatching process to take place in a relatively controllable space. Its stable internal environment helps maintain the relative stability of factors such as water temperature and water quality, thereby creating favorable conditions for egg hatching and fry growth, improving the safety and stability of fry hatching, reducing the negative impact of uncontrollable external factors on fry hatching, and thus helping to improve the survival rate and quality of fry. The mesh plate 2 is placed horizontally inside the incubation box 1, serving as support and layering. The mesh box 3 is placed on the mesh plate 2 and is used specifically to hold the fish eggs. Fish eggs are placed in an orderly manner in net cage 3. The mesh structure of net cage 3 ensures that the fish eggs can fully contact the water flow during the hatching process, while preventing the fish eggs from scattering or piling up due to water flow impact or other factors. This design can avoid damage caused by mutual squeezing of fish eggs, ensure good water exchange and sufficient dissolved oxygen around the fish eggs, which is conducive to the normal development of fish eggs and reduces abnormal embryonic development and death caused by squeezing, lack of oxygen and other factors, thereby improving the hatching rate and quality of fish fry and further ensuring the survival rate of fish fry. Heating rod 4 is installed in hatching box 1, which heats the hatching water according to the preset temperature value and maintains it at a stable constant temperature. The heater 4 automatically starts heating when the water temperature is lower than the set suitable temperature range for hatching California bass fry. Once the water temperature reaches the set value, the heater 4 stops heating, ensuring the water temperature remains within a stable range, such as 25℃-28℃ (the specific temperature can be optimized and adjusted according to actual conditions). This effectively overcomes the problems of seasonal water temperature fluctuations and large diurnal temperature differences in natural environments, providing stable and suitable temperature conditions for fish egg hatching. This makes the hatching cycle more stable and predictable, avoiding abnormal embryonic development caused by unstable temperatures, significantly reducing the probability of deformed fry, greatly improving the overall quality and survival rate of fry, and ensuring healthy growth and efficient production. The oxygen pump 6 is fixedly installed inside the base box 5, which protects and supports the oxygen pump 6 and also isolates the noise generated by the oxygen pump 6 during operation to a certain extent. Oxygen pump 6 is connected to aeration head 8 via air pipe 7. Aeration head 8 is placed in the water inside the hatching tank 1. When oxygen pump 6 is working, it compresses air and delivers it to aeration head 8 through air pipe 7. Aeration head 8 disperses the air into tiny bubbles and releases them evenly into the water, increasing the dissolved oxygen content in the water. Sufficient and stable dissolved oxygen supply is crucial for the growth and development of California bass fry, especially in the early stages of fry hatching when the embryos have a high demand for oxygen.By continuously and stably aerating and oxygenating, the dissolved oxygen level in the water can be maintained at a level suitable for the survival and development of fish fry, avoiding fish fry death due to lack of oxygen, further improving the survival rate of fish fry, and also helping the fish fry grow healthily, enhancing their vitality and immunity; the mounting frame 9 is set on the incubation box 1, and together with the base box 5, it supports and fixes the filtration mechanism. The filtration mechanism is stably installed in a suitable position via the mounting bracket 9 and the base box 5, circulating and filtering the hatching water. Good water quality is the foundation for the healthy growth of fish fry. The filtration mechanism can effectively remove various pollutants and harmful substances from the water, preventing water quality deterioration from harming the fish fry, reducing the risk of disease infection, and providing a clean and stable living environment for the fish fry. This is conducive to the normal growth and development of the fish fry, improving the survival rate and quality of the fish fry, ensuring high-efficiency production of fish fry, and also reducing the frequency and workload of water changes, thus lowering breeding costs and labor intensity. In summary, this utility model, through the synergistic effect of various components, addresses multiple key aspects such as temperature, dissolved oxygen, and water quality, effectively solving the problem of reduced hatching survival rate of California bass fry in natural environments. It provides an efficient and stable fish fry hatching device for the artificial breeding of California bass, with significant practical value and economic benefits, and helps to promote the development and expansion of the California bass farming industry.

[0023] In a further preferred embodiment of this utility model, the filtration mechanism includes: a filter box 11 disposed on the mounting frame 9 for holding filter media; a filter box 12 disposed in the filter box 11 for placing filter cotton and which can be pulled out and removed; a deluge pipe 13 disposed in the filter box 11; a drain pipe 18 fixedly connected to the bottom of the filter box 11, the outlet end of the drain pipe 18 extending into the incubation box 1 for supplying filtered water; and a water pump 14 fixedly installed in the base box 5 for pumping water, the inlet end of the water pump 14 being connected to the incubation box 1 through a water pumping pipe 15, and the outlet end of the water pump 14 being connected to the deluge pipe 13 through a water outlet pipe 17.

[0024] In this embodiment, the filter box 11, as the core supporting component of the filtration mechanism, is securely installed in the corresponding position of the hatching box 1 via the mounting bracket 9. It provides a centralized space for the filter media, allowing the entire filtration process to proceed in a relatively closed and orderly environment. Its presence makes the filtration system structure more compact and orderly, which is beneficial for improving filtration efficiency and stability, preventing the filter media from scattering and affecting the environment inside the hatching box, and facilitating centralized management and maintenance of the filtration process. This ensures the continuity and reliability of water purification, providing stable and clean hatching water for California bass fry, and helps improve the survival rate and health of the fry. The filter box 12 is placed inside the filter box 11 and is specifically used to hold filter cotton. It is designed to be removable and pull-out. When it is necessary to replace or clean the filter cotton, the operator can easily pull the filter box 12 out of the filter box 11, perform the corresponding operations, and then reinstall it. This removable and pull-out design greatly improves the convenience of filter cotton replacement and cleaning, reducing maintenance costs and labor intensity. Regularly replacing and cleaning the filter cotton ensures the stability of the filtration effect, effectively intercepting tiny particulate impurities, some organic matter, and microorganisms in the water, preventing them from accumulating in the water and harming the fish fry, further ensuring the cleanliness of the water quality, creating a better living environment for the fish fry, and thus improving the hatching success rate and growth quality of the fish fry; the deluge pipe 13 is installed inside the filter box 11 and connected to the outlet pipe 17. The water pump 14 draws water from the hatching box 1 and delivers it to the deluge pipe 13 through the outlet pipe 17. The water is then sprayed evenly from the numerous small holes of the deluge pipe 13, dripping onto the filter media and filter cotton; this uniform water spraying method of the deluge pipe 13 can make the water flow evenly distributed throughout the filtration area, making full use of the filtration area of ​​the filter media and filter cotton, and improving the filtration effect. Compared to direct rinsing, the rain shower method reduces the impact of water flow on the filter media and filter cotton, preventing damage to the filter media structure and extending its service life. It also allows for more sufficient contact time between the water and the filter media and filter cotton, more effectively removing impurities, harmful substances, and microorganisms from the water. This ensures the quality of the water flowing into the hatching tank 1, providing strong support for the healthy growth of California bass fry and improving their survival rate. One end of the drain pipe 18 is fixedly connected to the bottom of the filter box 11, and the other end extends into the hatching tank 1. Filtered water returns to the hatching tank 1 through the drain pipe 18, completing the entire water circulation filtration process. This ensures that the filtered clean water can flow back to the hatching tank 1 stably and orderly, maintaining a stable water level in the hatching tank 1, while avoiding direct impact of water flow on the fish eggs and fry, providing a relatively quiet and stable living environment for the fry.Stable water circulation and water level are crucial for the growth and development of fish fry. They help reduce stress caused by unstable water flow, improve the survival rate and growth vitality of fish fry, and ensure high-efficiency production of fish fry. The water pump 14 is fixedly installed in the base box 5. Its water inlet is connected to the incubator 1 through the water pumping pipe 15 to draw water from the incubator 1. Its water outlet is connected to the deluge pipe 13 through the water outlet pipe 17 to transport the drawn water to the deluge pipe 13 for filtration. The water pump 14 serves as the power source for water circulation. Through the water pumping pipe 15 and the water outlet pipe 17, a stable and efficient water circulation system is constructed, ensuring that water can be continuously drawn from the incubator 1, purified by the filtration mechanism, and then returned to the incubator 1. This stable water circulation can promptly remove pollutants and harmful substances from the water, maintaining clean and stable water quality. This provides a good living environment for California bass fry, promoting their normal development, reducing the risk of death due to water quality deterioration, and improving the overall survival rate and quality of the fry. It also facilitates the efficient and stable hatching process of California bass fry. In summary, the filtration mechanism in this embodiment, through the ingenious design and coordinated operation of its various components, optimizes the water purification process in multiple aspects, including filtration methods, filter media replacement and maintenance, and water circulation. It effectively solves the water quality problems during the hatching process of California bass fry, providing a solid guarantee for the healthy growth and high survival rate of the fry. This further enhances the practicality and reliability of this indoor incubator, demonstrating significant economic benefits and application value.

[0025] In a further preferred embodiment of the present invention, an adjustable LED light 10 is fixedly installed on the mounting bracket 9, and a detachable cover plate 19 is provided on the top of the filter box 11.

[0026] In this embodiment, the LED light 10 is fixedly mounted on the mounting bracket 9. Through a suitable control device (such as a dimmer, timer, or other control system), the light intensity and duration can be precisely controlled according to the light requirements of different growth stages of the California bass fry. In the early stages of fry hatching, a lower light intensity and shorter light duration can be set to simulate the weak light conditions in the natural environment, avoiding strong light stimulation of embryonic development. As the fry gradually grow, the light intensity and duration can be appropriately increased to promote feeding, activity, and growth. Suitable light conditions play a crucial role in the growth and development of California bass fry. Appropriate light intensity and duration can regulate the fry's biological clock, promoting the normal operation of their physiological functions, such as increasing their appetite, enabling them to better absorb nutrients, and enhancing their constitution and immunity. Meanwhile, a stable and controllable lighting environment helps reduce stress responses in fish fry, avoids behavioral abnormalities and growth stagnation caused by unsuitable lighting, thereby improving the survival rate and growth quality of fish fry, providing the necessary environmental conditions to support the healthy growth of California bass fry, and ensuring high-efficiency production and aquaculture benefits.

[0027] In a further preferred embodiment of the present invention, support columns are symmetrically fixedly installed at the bottom of the base box 5, and foot pads are fixedly installed on the bottom end of the support columns.

[0028] In this embodiment, the support columns are symmetrically and fixedly installed at the bottom of the base box 5, and foot pads are fixedly connected to their bottom ends. With this structure, the entire incubator is stably supported on the ground or a flat surface, ensuring that it is in a horizontal and stable state.

[0029] In a further preferred embodiment of the present invention, limiting cylinders are fixedly installed on both sides of the incubator 1, and the limiting cylinders are adapted to the mounting frame 9 for limiting its position.

[0030] In this embodiment, the limiting cylinders are fixedly installed on both sides of the incubator 1, and their shape and size are adapted to the mounting frame 9. The mounting frame 9 is installed along the direction of the limiting cylinders so that the mounting frame 9 can be accurately embedded into the position defined by the limiting cylinders, thereby achieving precise positioning of the mounting frame 9.

[0031] In a further preferred embodiment of the present invention, both the cover plate 19 and the filter box 12 are fixedly installed with handles for gripping, and the water inlet end of the water pumping pipe 15 is provided with a basket head 16.

[0032] In this embodiment, handles are fixedly installed on the cover plate 19 and the filter box 12 respectively. When it is necessary to operate the filter box 11, such as opening the cover plate 19 to check or replace the filter media, or pulling out the filter box 12 to clean or replace the filter cotton, the operator can easily complete these actions by gripping the handle.

[0033] In a further preferred embodiment of the present invention, a constant temperature controller is provided on the outer wall of the incubator 1, and the constant temperature controller is adapted to the constant temperature heating rod 4.

[0034] In this embodiment, a thermostat is installed on the outer wall of the incubator 1. A temperature sensor (which can be built into a suitable location inside the incubator 1 and connected to the thermostat) monitors the water temperature inside the incubator 1 in real time. When the water temperature is lower than the preset suitable temperature range for hatching California bass fry, the thermostat automatically starts and adjusts the heating rod 4 to increase its power for heating. When the water temperature reaches or exceeds the set temperature, the thermostat controls the heating rod 4 to reduce its power or stop heating, thereby accurately maintaining the water temperature at the set constant temperature, for example, stabilizing the water temperature at 25℃-28℃ (the specific temperature can be adjusted according to the actual needs of fry hatching).

[0035] In summary, by providing a stable space through the hatching box 1, ensuring a good environment for the fish eggs through the mesh plate 2 and mesh cage 3, stabilizing the water temperature through the heater 4, ensuring dissolved oxygen through the oxygen pump 6, air pipe 7, and aeration head 8, and optimizing water quality purification through the mounting frame 9 and the filtration mechanism, the coordinated action of these components effectively solves the problem of low hatching and survival rates of California bass fry in natural environments. By creating a suitable growth environment for the fry from key aspects such as temperature, dissolved oxygen, and water quality, the hatching rate, survival rate, growth quality, and vitality of the fry are improved, while reducing external interference and disease risks, lowering maintenance costs and labor intensity, and achieving efficient and stable fry hatching.
