This kind of culture method has the following problems: (1) When culturing fish fry and fingerlings in stages, the size of the cultured objects changes in different culture stages. Therefore, manual tank transfer is often required, and the fish fry and fingerlings are easily injured during the manual tank transfer process. (2) Multiple culture tanks with different diameters need to be used. Therefore, a large number of pipelines are adopted, with high consumables, high water consumption, large floor area, and low environmental protection and economy. Specifically, when arranging the culture tanks, a certain space distance needs to be reserved between individuals, and a large number of inlet and outlet pipelines, water supply and drainage pipes, etc. are required. Therefore, it occupies a large space, consumes a lot of materials, has a large water consumption, and has a low recycling rate of water bodies. Most water conservancy and hydropower projects are mainly built in mountainous areas, where the available land is tense, and it is difficult to arrange a large area of culture tanks, which brings certain difficulties to the implementation of environmental protection projects. (3) For culture tanks of different sizes, it is difficult to create different flowing water environments and adjust the water depth, etc., and it is difficult to meet the water body requirements of different types of cultured objects, resulting in poor culture effects and low utilization rates.

It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0030] The present utility model provides a multi-functional fish breeding and cultivation facility, which uses intensive cultivation facilities to solve the problems of hatching sticky and sedimentary fertilized eggs, cultivating fish with different habits, and partitioning and cultivating fish at different stages and of different specifications, realizing the production and cultivation of all stages from broodstock cultivation, broodstock spawning and fertilization, fertilized egg hatching to fry cultivation, fry culture, and fingerling cultivation, avoiding the artificial harm caused to fish by frequently changing cultivation facilities during the cultivation process, and improving the cultivation efficiency and effect of fish.

[0031] Refer to Figures 1 to 6 , the present utility model provides a multi-functional fish breeding and cultivation facility, including a hatching spraying facility 1, a movable partition 2, a cultivation water inlet pipe 3, a cultivation cylinder 4 and a cultivation water outlet pipe 5;

[0032] One end of the breeding tank body 4 is connected to the breeding water inlet pipe 3, and the other end is connected to the breeding water outlet pipe 5; inside the breeding tank body 4, along the water flow direction, the depth of the tank body gradually increases; specifically, the breeding tank body 4 is a cuboid water tank with a slope that gradually deepens along the water flow direction at the bottom of the tank, so as to achieve the effect of gradually increasing the depth of the tank body.

[0033] On the inner wall of the breeding tank body 4, partition slots 4-1 are arranged at intervals along the water flow direction, and a movable partition 2 is inserted and installed in each partition slot 4-1; each movable partition 2 is arranged in parallel and obliquely, and the included angle between the water-facing surface and the water flow direction is greater than 90 degrees. Through each movable partition 2, the breeding space of the breeding tank body 4 is divided into multiple breeding partitions; an incubation spraying facility 1 is arranged above the breeding tank body 4 for spraying water bodies into each breeding partition.

[0034] As an embodiment, refer to Figure 5 and Figure 6 , the movable partition 2 includes a partition outer frame body 2-1, an impermeable solid plate 2-2, a permeable grid structure 2-3 and a pull-out impermeable movable plate 2-4;

[0035] The partition outer frame body 2-1 matches the shape of the partition slot 4-1; an impermeable solid plate 2-2 is fixedly installed below the inside of the partition outer frame body 2-1; a permeable grid structure 2-3 is fixedly installed above the inside of the partition outer frame body 2-1; a pull-out impermeable movable plate 2-4 that can slide up and down with the partition outer frame body 2-1 is arranged on the front side of the impermeable solid plate 2-2.

[0036] As an embodiment, the incubation spraying facility 1 includes a main water inlet pipe 1-1, a branch water inlet pipe 1-2 and a spray head 1-3;

[0037] On the main water inlet pipe 1-1, at the position corresponding to each breeding partition, a branch water inlet pipe 1-2 is led out, and a spray head 1-3 facing the breeding partition is installed at the top of the branch water inlet pipe 1-2.

[0038] On the water surface of each breeding partition, an incubation frame 6 with adjustable position as shown in Figure 4 is provided. The incubation frame 6 has an outer frame 6-1 with a fixed height and an inner frame 6-2 with adjustable height relative to the outer frame 6-1. The inner frame 6-2 is provided with a net, and by adjusting the height of the net, the requirements for the submerged height of different fertilized eggs are met.

[0039] The utility model provides a multifunctional fish breeding and farming facility. The breeding tank body 4 adopts a rectangular cross-section instead of a circular cross-section, and the depth of the breeding tank body 4 gradually increases along the water flow direction. Moreover, by flexibly adjusting the installation of the movable partition 2 at different positions, the breeding partition with a certain depth range and a certain space distance is separated by the movable partition 2, so as to meet the breeding space and water depth requirements of breeding bodies of different sizes and at different stages. Then, by adjusting the top water-permeable height of each movable partition 2 and the spraying speed of the hatching spraying facility 1 to the breeding partition, the water flow velocity in the breeding partition can be flexibly adjusted. Therefore, this structure can create different water depths, space sizes and flow velocities in the breeding tank body, provide multiple breeding environments for fish, and meet the breeding environment requirements of different types and sizes of fish.

[0040] The specific working process is as follows:

[0041] (1) A plurality of movable partitions 2 are arranged at intervals in the breeding tank body 4, and a breeding partition is formed between every two movable partitions 2; since the movable partition 2 and the partition slot 4-1 of the breeding tank body 4 are detachably connected, therefore, the movable partition 2 can be flexibly installed or removed at different positions, and further, the space size of a certain breeding partition can be adjusted to meet the breeding environment requirements of fish.

[0042] For example, when breeding two breeding individuals of different sizes, assuming that a total of 4 movable partitions 2 can be set from the water inlet end to the water outlet end of the breeding tank body 4, which are respectively: the first movable partition, the second movable partition, the third movable partition and the fourth movable partition; then a first breeding partition is formed between the water inlet end of the breeding tank body 4 and the first movable partition, a second breeding partition is formed between the first movable partition and the second movable partition, a third breeding partition is formed between the second movable partition and the third movable partition, and a fourth breeding partition is formed between the third movable partition and the fourth movable partition;

[0043] If the sizes and depths of the first breeding partition and the fourth breeding partition respectively meet the breeding requirements of the first breeding individual and the second breeding individual, then directly use the first breeding partition to breed the first breeding individual and use the fourth breeding partition to breed the second breeding individual. At this time, since there is a distance interval between the first breeding partition and the fourth breeding partition, the breeding interval requirements of the breeding individuals are simultaneously met.

[0044] If the first breeding partition is small and cannot meet the breeding requirements of the first breeding individual, the first movable partition can be removed, so that a larger breeding partition is formed between the water inlet end of the breeding tank body 4 and the second movable partition, so as to meet the breeding requirements of the first breeding individual. Similarly, if the space between the water inlet end of the breeding tank body 4 and the second movable partition is still small, the second movable partition can be removed, so that a larger breeding partition is formed between the water inlet end of the breeding tank body 4 and the third movable partition.

[0045] Therefore, according to the actual aquaculture space requirements, the position and quantity of the movable partitions installed in the aquaculture cylinder body 4 can be adjusted arbitrarily, so as to meet the requirements of the cultured individuals for the aquaculture space and depth.

[0046] Based on the same concept, when a certain aquaculture partition conducts phased cultivation of a certain cultured individual, as the volume of the cultured individual increases, the movable partition of this aquaculture partition can be removed, and the space of the aquaculture partition can be expanded to meet the aquaculture environment requirements of the fish.

[0047] (2) Further, for the movable partition 2 used to separate the aquaculture partitions, the bottom is an impermeable solid plate 2-2, the upper part is a permeable grid structure 2-3, and the outside is wrapped with a fishing net with a replaceable aperture. At the same time, a pullable impermeable movable plate 2-4 is provided. By sliding the pullable impermeable movable plate 2-4 to different height positions of the movable partition 2, the overflow water level can be adjusted to create different water depths and flow rates in the aquaculture cylinder body, providing a variety of aquaculture environments for the fish.

[0048] (3) Further, a tubular hatching spray facility 1 is provided at the upper part of this facility, and at the same time, a square hatching frame 6 with a fixed periphery and a mesh in the middle floats on the water surface for the hatching of adhesive eggs.

[0049] When this facility operates, water enters from the aquaculture water inlet pipe 3. The movable partition 2 is inserted into the aquaculture cylinder body 4, and the pullable impermeable movable plate 2-4 in the movable partition 2 is pulled to control the water level to the highest. The water level in the aquaculture cylinder body 4 is controlled by overflow drainage through the movable partition 2;

[0050] The adhesive fertilized eggs are laid flat in the hatching frame 6, and the hatching frame 6 with the fertilized eggs is placed in the aquaculture cylinder body 4 and floats on the water surface. The hatching spray facility 1 is opened to spray the fertilized eggs in the hatching frame to keep the water body flowing and changing, so that the adhesive fertilized eggs hatch.

[0051] The newly hatched fry are directly diluted into the aquaculture cylinder body 4 for the cultivation of newly hatched fry. As the density of the newly hatched fry increases continuously with the hatching of the fertilized eggs, continuous dilution cultivation is carried out in the aquaculture cylinder body 4 until the cultivation of the newly hatched fry is completed.

[0052] According to the habits of different fry and fish species, the water depth and flow rate in the aquaculture cylinder body 4 are adjusted through the pullable impermeable movable plate 2-4 of the movable partition 2 to create different flow rates to adapt to the cultivation of fry of different sizes and habits. Thus, the classification and grading cultivation of fry and fish species can be flexibly realized until they are released.

[0053] The present utility model provides a multi-functional fish breeding and cultivation facility, which has the following advantages: (1) Inside the cultivation facility, inclined movable partitions are adopted at certain intervals to control the water depth of cultivation and create different water flow velocities in the water body so as to meet the requirements of different fish at different stages for different water flow velocities and water depths. (2) After the fertilized eggs are hatched in the facility, they can be directly diluted in this facility for the cultivation of the newly hatched fry. As the fry grow, the water depth in the cultivation facility can be adjusted by the movable partitions to meet the requirements of the growing individuals for a larger water body. At the same time, the size of the cultivation space can be controlled by the number of movable partitions to match the requirements of the fish for the space size. The requirements for a high density or the growth of individuals for the water body can be completed by direct dilution in this facility without the need for tank transfer operations.

[0054] The multi-functional fish breeding and cultivation facility provided by the present utility model has the following advantages: (1) The present utility model can effectively save land, save water and improve the utilization rate of the water body; (2) The present utility model can reduce the damage to fish caused by humans, thereby improving the cultivation effect; (3) The present utility model has the advantages of environmental protection, etc. It is a fish breeding and cultivation facility that integrates hatching and grading cultivation, is easier to manage and operate.

[0055] The above are only the preferred embodiments of the present utility model. It should be noted that for those of ordinary skill in the art of this technology, without departing from the principle of the present utility model, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present utility model.
