[0029] Referring to Figure 1 , Figure 2 , Figure 3The fish fry cultivation system provided by the embodiment of the utility model can be used for cultivating fish fry such as catfishes, wherein the fish fry cultivation system comprises a breeding tank 100, a cultivation tank 200 and a circulating device 300; the breeding tank 100 is used as a container for containing breeding water and is used for breeding fish fry that need to be cultivated; the cultivation tank 200 is provided with cultivation substrates and bacteria strains for cultivating beneficial bacteria; the beneficial bacteria can be cultivated through the cultivation tank 200; the cultivated beneficial bacteria are delivered to the breeding tank 100 as the feed of the fish fry; and the circulating device 300 is used for delivering the water in the breeding tank 100 to the cultivation tank 200 and making the water delivered to the cultivation tank 200 backflow to the breeding tank 100.
[0030] The fish fry cultivation system combines fish fry cultivation and beneficial bacteria cultivation together, utilizes the water in the cultivation tank to cultivate beneficial bacteria, and makes the cultivated beneficial bacteria injected into the breeding tank 100 through the backflow water, which not only simplifies the fish fry cultivation process, reduces the manual input and lowers the fish fry cultivation cost, but also fully utilizes the organic nutrients in the breeding water to cultivate beneficial bacteria and reduces the carbon dioxide content in the water, so that the fish fry cultivation system can automatically optimize the water quality and is beneficial to the cultivation of fish fry.
[0031] Referring to Figure 1 , Figure 2 , Figure 3 In some embodiments, the cultivation tank 200 is arranged on the breeding tank 100, connected with the breeding tank 100 and located above the breeding tank 100, so that the beneficial bacteria cultivated by the cultivation tank 200 can naturally fall into the breeding tank 100, and thus the beneficial bacteria do not need to be manually transported additionally, further reducing the manual input.
[0032] Specifically, referring to Figure 1 , Figure 2 , Figure 3 Along the circumference of the breeding tank 100, a step 110 is arranged on the upper part of the tank body of the breeding tank 100, and a support 210 is arranged at each corner of the cultivation tank 200, the support 210 can improve the strength of the cultivation tank 200, the bottom of the support 210 abuts against the step 110, and through the cooperation of the step 110 and the support 210, the positioning of the cultivation tank 200 on the breeding tank 100 can be realized.
[0033] Referring to Figure 1 , Figure 2 In some embodiments, a water distributor is arranged on the cultivation tank 200, and the water distributor is used for uniformly distributing the water delivered by the circulating device 300 to the cultivation tank 200.
[0034] Specifically, the water distributor is a container with an internal cavity. Multiple water distribution holes, each with a small diameter, are provided on the bottom plate of the water distributor, distributed across the entire bottom plate. In some specific embodiments, the water distribution holes are evenly distributed across the entire bottom plate. The circulation device 300 delivers water from the aquaculture tank 100 to the water distributor. The water flows along the water distribution holes into the cultivation tank 200 and drips evenly onto the cultivation substrate within the cultivation tank 200, moistening the beneficial bacteria and thus utilizing the organic nutrients in the aquaculture water to cultivate beneficial bacteria. The water distributor effectively moistens the cultivation substrate within the cultivation tank 200, preventing the beneficial bacteria on some substrates from failing to receive nutrients.
[0035] Reference Figure 1 , Figure 2 , Figure 3 In some embodiments, the circulation device 300 includes a circulation tank 310 and a circulation pump 320. The circulation tank 310 is used to receive water overflowing from the breeding tank 100. The circulation pump 320 is disposed in the circulation tank 310 to transport the water in the circulation tank 310 to the breeding tank 200. By using the circulation tank 310, the circulation pump 320 can be avoided from being directly disposed in the breeding tank 100, thus preventing the noise generated by the circulation pump 320 from affecting the growth of the fish fry and avoiding damage to the fish fry during the water extraction process.
[0036] Reference Figure 1 , Figure 2 , Figure 3 In some embodiments, the aquaculture tank 100 is equipped with a water level controller 400, which is used to control the water level in the aquaculture tank 100 so that the water in the aquaculture tank 100 overflows into the circulation tank 310.
[0037] Specifically, refer to Figure 4In the specific embodiment shown in the figure, the water level controller 400 includes an inlet pipe 410, a connecting pipe 420, and an overflow pipe 430. The inlet pipe 410 is located near the bottom of the breeding tank 100. The overflow pipe 430 is located vertically inside the breeding tank 100. One end of the overflow pipe 430 near the bottom of the breeding tank 100 extends to the outside of the breeding tank 100. One end of the connecting pipe 420 is connected to the inlet pipe 410, and the other end is connected to the end of the overflow pipe 430 away from the bottom of the breeding tank 100. Water in the breeding tank 100 enters the connecting pipe 420 through the inlet pipe 410. When the fish fry rearing system is in use, circulating water is pressurized by the circulating pump 320, injected into the water distributor through the water supply pipe 321, and then enters the rearing tank 200 through the water distributor. The organic nutrients in the water supply organic bacteria and degrade carbon dioxide in the water. The water flows back from the rearing tank 200 to the rearing tank 100, and the cultivated beneficial bacteria also drip into the rearing tank 100 through the return water to nourish the fish fry. As the circulating pump 320 continuously replenishes water to the water distributor, the water level in the rearing tank 100 continues to rise, and the water level in the connecting pipe 420 rises synchronously. When the water level rises to the connection port of the connecting pipe 420 and the overflow pipe 430 away from the bottom of the rearing tank 100, the water in the rearing tank 100 is discharged through the connecting pipe 420 into the overflow pipe 430, and then into the circulating tank 310 through the overflow pipe 430. It is then pumped back into the water distributor by the circulating pump 320, and so on, so that the rearing tank 100 operates at the normal water level.
[0038] It is understandable that the water level controller 400 may also adopt other structures, such as setting an overflow port on the side wall of the breeding tank 100, and controlling the water level in the breeding tank 100 through the overflow port, which is not limited here.
[0039] Reference Figure 2 , Figure 3 In some embodiments, the overflow pipe 430 located outside the breeding tank 100 is connected to a three-way pipe 440. The first end of the three-way pipe 440 is connected to the overflow pipe 430, and the second end of the three-way pipe 440 is connected to a fry collection pipe 450. The fry collection pipe 450 is equipped with a first control valve 451, allowing the fish fry in the breeding tank 100 to be discharged and collected after they have grown. The third end of the three-way pipe 440 is connected to a water outlet pipe 460, which is equipped with a second control valve 461. The water outlet pipe 460 is used to overflow water from the breeding tank 100 to the circulation tank 310.
[0040] Reference Figure 2 , Figure 3 In some embodiments, a drain pipe 470 is connected to the seedling collection pipe 450, and a third control valve 471 is provided on the drain pipe 470. When cleaning the breeding tank 100, the cleaning sewage and dirt can be discharged through the drain pipe 470.
[0041] In some embodiments, a filter is provided in the circulation tank 310. The feces produced by the fish fry in the breeding tank 100 are discharged into the circulation tank 310 through the water level controller 400 and the water outlet pipe 460. The feces are filtered by the filter in the circulation tank 310 and then drawn to the water distributor, which distributes them evenly to the cultivation tank 200 to cultivate beneficial bacteria.
[0042] Filters can be microporous plate filters, sponge filters, etc., and, refer to Figure 1 , Figure 2 , Figure 3 In some embodiments, the circulation tank 310 can be divided into two or more compartments 311, each compartment 311 is equipped with a filter, so that the circulating water passes through multiple layers of filtration, improves the filtration effect of feces, and further enhances the cleanliness of the water and optimizes the cultivation environment.
[0043] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0044] Of course, this utility model is not limited to the above-described embodiments. Those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of this utility model. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
