Description

Technical Field

[0001] The utility model relates to the technical field of aquatic breeding equipment, in particular to a fish nest used for sticky fish eggs. Background Art

[0002] Sticky fish eggs are those that have a layer of mucus or sticky threads on their surface, a property that enables the eggs to attach to aquatic plants, rocks, branches or other solid surfaces. In artificial breeding conditions, the management of sticky fish eggs requires special attention because they do not float freely in open water bodies. In order to improve the hatching rate, farmers usually provide fish nests such as aquatic plants, mesh materials or special fish nest boxes for the fish eggs to attach to.

[0003] At present, when building fish nests for sticky fish eggs, water plants such as water plants are usually directly tied to ropes and then placed in the water. Water plants such as water plants float on the water surface, while the spawning position of sticky fish eggs is usually at the bottom of the water or near the bottom of the water. The current fish nests cannot well imitate the spawning grounds in the natural environment, and the height of the fish nest from the water surface cannot be adjusted. Utility Model Content

[0004] The utility model aims to provide a fish nest for sticky fish eggs, so as to solve the technical problems that the sticky fish egg artificial fish nest in the prior art cannot well imitate the spawning ground in the natural environment and cannot adjust the height of the fish nest from the water surface.

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] like Figure 1 and Figure 2As shown, the present invention provides a fish nest for sticky fish eggs, which mainly uses the cooperation of a float 4 and a counterweight block 6 to make artificial water plants 3 suspended in water.

[0022] The fish nest for sticky fish eggs comprises a frame 1, a fixing plate 2 is fixedly connected to the frame 1, and a plurality of artificial water plants 3 are detachably connected to the fixing plate 2;

[0023] A floating ball 4 is provided on the top of the frame 1, and the floating ball 4 is fixed to the frame 1 by a connecting rope 5, and a counterweight block 6 is connected to the bottom of the frame 1. The buoyancy generated by the floating ball 4 and the gravity generated by the counterweight block 6 act together to make the artificial waterweed 3 suspended in the water;

[0024] By changing the length of the connecting rope 5 between the buoy 4 and the frame 1 and the weight of the counterweight 6, the height of the bottom of the artificial waterweed 3 from the water bottom can be adjusted.

[0025] At present, when building fish nests for sticky fish eggs, water plants such as water plants are usually directly tied to ropes and then placed in the water. Water plants such as water plants will float on the water surface, which is inconsistent with the phenomenon that in the natural environment, the spawning position of sticky fish eggs is usually at the bottom of the water or near the bottom of the water. Therefore, it is necessary to develop a spawning fish nest that can well imitate the natural environment of sticky fish eggs.

[0026] In this embodiment, the artificial water plants 3 are suspended in the water by the cooperation of the float 4 and the counterweight 6. The height of the bottom of the artificial water plants 3 from the water bottom can be adjusted by adjusting the length of the connecting rope 5 and changing the weight of the counterweight 6. This allows the artificial water plants 3 to be located at or near the water bottom, which can well imitate the spawning ground of sticky fish eggs in the natural environment.

[0027] In actual use, the artificial water grass 3 is first fixed on the fixed plate 2, and then the float 4 is fixed to the frame 1 through the connecting rope 5. The device is placed in the water, and the artificial water grass 3 is suspended in the water by constantly adjusting the length of the connecting rope 5 and changing the weight of the counterweight 6, so that the height of the top of the artificial water grass 3 meets the requirements.

[0028] As a preferred embodiment of this embodiment, a ruler 7 is fixedly connected to the fixing plate 2. The ruler 7 indicates the distance between the bottom of the artificial water grass 3 and the water surface, so as to facilitate the control of the height of the bottom of the artificial water grass 3 from the water bottom.

[0029] The specific structure of the artificial water grass 3 is as follows: Figure 2 and Figure 3As shown, a plurality of mounting seats 8 are fixedly connected to the fixing plate 2, and the artificial water grass 3 includes a connecting seat 9 and a plurality of supporting bars 10 fixedly connected to the connecting seat 9. The connecting seat 9 is snap-fitted or threadedly connected to the mounting seat 8, so that the artificial water grass 3 is detachably connected to the fixing plate 2. The detachable connection between the artificial water grass 3 and the fixing plate 2 is achieved by the detachable connection seat 9 and the mounting seat 8.

[0030] Furthermore, a plurality of bristles 11 are fixedly connected to the outer surface of the support bar 10, and a plurality of protrusions 12 are fixedly connected to the bristles 11. By providing a plurality of bristles 11 and a plurality of protrusions 12, the attachment area and attachment stability of the sticky fish eggs can be increased.

[0031] The above embodiments are only exemplary embodiments of the present application and are not intended to limit the present application. The protection scope of the present application is defined by the claims. Those skilled in the art may make various modifications or equivalent substitutions to the present application within the essence and protection scope of the present application, and such modifications or equivalent substitutions shall also be deemed to fall within the protection scope of the present application.
