Generally, it includes the whole process of cultivating aquatic products from fry under artificial feeding and management. In a broad sense, it can also include the enhancement of aquatic resources. Aquaculture has methods such as extensive culture, intensive culture and high-density intensive culture. Extensive culture is to put fry in medium and small natural waters and completely rely on natural bait to grow aquatic products, such as fish farming in lakes and reservoirs and shellfish farming in shallow seas. Intensive culture is to grow aquatic products by feeding and fertilizing in a smaller water body, such as pond fish farming, cage fish farming and enclosure culture. High-density intensive culture uses methods such as flowing water, temperature control, oxygenation and feeding high-quality bait to carry out high-density culture in a small water body to obtain high yields, such as high-density fish and shrimp farming in flowing water.

[0022] The following describes the specific implementation of a novel fishing device for aquaculture in detail in conjunction with specific embodiments.
[0023] Reference Figures 1 to 3 , a fishing device for aquaculture provided by the present utility model includes: a box body 1 with openings at the top and bottom. A plurality of water outlet holes 6 are provided on the side surface of the box body 1. The top of the box body 1 is connected to the bottom of a support plate 2 through a bracket 3. The protection net 7 is rotatably connected to all side surfaces of the support plate 2. A baffle 8 for restricting the outward rotation of the protection net 7 is provided at the top of the box body 1 on one side of the protection net 7. The lower end inside the box body 1 is movably connected to a partition 9. A plurality of fish outlet holes 12 are provided at the top of the partition 9. The number of partitions 9 is multiple, and the inner diameter sizes of the fish outlet holes 12 of different partitions 9 are different.
[0024] It should be noted that: through the fish outlet holes 12, small fish swim out from the fish outlet holes 12, preventing small fish from being easily caught together during fishing, which is not conducive to the sustainability of ecological aquaculture. And during fishing, fish automatically enter the inside of the box body 1 without using forced means. Therefore, it will not cause damage to the fish, resulting in the death of the fish, and thus causing relatively serious economic losses.
[0025] In an embodiment of the present utility model, with reference to Figure 3 as shown, an installation hole 13 is provided on the side surface of the box body 1, and an installation groove 14 is provided on the inner wall of the box body 1 opposite to the installation hole 13. The two ends of the partition 9 are respectively movably connected to the installation hole 13 and the installation groove 14.
[0026] It should be noted that: by providing the installation hole 13 and the installation groove 14, they can be connected to the two ends of the partition 9 and support the partition 9, improving the stability of the partition 9 when placed, and preventing the partition 9 from shaking and shifting when being impacted by fish, affecting subsequent use.
[0027] In an embodiment of the present utility model, with reference to Figure 1 as shown, a limiting plate 10 is rotatably connected to the outer surface of the box body 1 outside the installation hole 13. The number of limiting plates 10 is multiple, and the limiting plates 10 are linearly arranged at equal intervals on the outer surface of the box body 1.
[0028] It should be noted that by setting the limiting plate 10, when the partition plate 9 is placed in the mounting hole 13, the side surface of the limiting plate 10 can be brought into contact with the partition plate 9 by rotating the baffle plate 8, so as to limit the partition plate 9 and prevent the partition plate 9 from shaking and shifting when being impacted by fish, which may affect subsequent use.
[0029] In an embodiment of the present invention, as shown in Figure 1 the two ends of the top of the support plate 2 are respectively provided with a first connecting ring 4 and a second connecting ring 5, and the shapes of the first connecting ring 4 and the second connecting ring 5 are both U-shaped.
[0030] It should be noted that by setting the U-shaped first connecting ring 4 and second connecting ring 5, the box body 1 can be connected to the first connecting ring 4 and the second connecting ring 5 through a hook, which is convenient for moving the box body 1 up and down, and thus convenient for adjusting the depth of the box body 1 in the water.

[0035] The working principle of a fishing device for aquaculture provided by the present invention is as follows:
[0036] During use, the fishing device can be placed inside the water body. When the fish are swimming, since the protective net 7 can rotate inward but not outward, when the fish hit the protective net 7, the protective net 7 is driven to rotate inward. At this time, the fish enter the inside of the box body 1, and under the action of gravity, the protective net 7 returns to its original position to block the fish and prevent it from swimming out of the water tank, thus realizing the fishing of the fish. And by providing a partition plate 9 with a fish outlet hole 12 at the lower end inside the box body 1, small fish can swim out through the fish outlet hole 12, preventing small fish from being captured together during fishing, which is not conducive to the sustainability of ecological aquaculture.
