Abstract
Description
Technical Field
[0001] This utility model relates to the field of fish fry technology, and more specifically, to a device for collecting eggs of the bryophyll carp. Background Technology
[0002] The bryophyll carp is distributed in the Pearl River system, the middle and upper reaches of the Yangtze River and its tributaries. It typically inhabits slow-flowing, rocky environments and can live in both rivers and lakes. The bryophyll carp has delicious flesh and a large yield, making it highly valuable for development and utilization. In artificial breeding of the bryophyll carp, open containers filled with gravel are usually placed at the bottom of the spawning pond. The fish lay their eggs on the gravel, and then the fertilized eggs are manually removed and separated from the gravel. This method has the following problems: the fish may eat the fertilized eggs, and the manual sifting process is time-consuming. Utility Model Content

[0006] Furthermore, an inclined surface is provided on the side of the groove, with the upper end of the inclined surface being closer to the outer periphery of the separation frame than the lower end of the inclined surface.
[0007] Furthermore, the separation frame includes an extension plate, which is positioned at the upper end of the collection box.
[0008] Furthermore, a sealing block is connected to the lower part of the extension plate, and the inner wall of the sealing block is set to fit against the outer wall of the collection box.
[0009] Furthermore, the outer wall of the collection box is provided with a locking block, and the inner wall of the sealing block is provided with a locking groove that cooperates with the locking block.
[0010] Furthermore, an egg collection frame is provided inside the collection box, located below the bottom of the separation frame. A support block is provided on the inner wall of the collection box, and the egg collection frame is placed on the support block. A filter screen is installed at the bottom of the egg collection frame.
[0011] Furthermore, an insert block is provided on the upper part of the support block, and an installation groove that mates with the insert block is provided at the bottom of the egg collection frame.
[0012] The beneficial effect of this invention is that the produced fish eggs fall into the collection box through the through hole for collection, which can prevent fish from swallowing the fertilized eggs. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0018] like Figures 1-3 As shown, a device for collecting eggs of a glossy bream includes a collection box 1. A separation frame 2 is provided on the upper part of the collection box 1. A groove 3 is provided in the middle of the upper part of the separation frame 2. The bottom of the separation frame 2 is located inside the collection box 1 and has several through holes 5. That is, the separation frame 2 has several through holes 5 corresponding to the bottom of the groove 3. The diameter of the through holes 5 is adapted to the particle size of the eggs produced by the glossy bream. Specifically, the diameter of the through holes 5 is slightly larger than the particle size of the eggs, so that the eggs can fall into the collection box 1 through the through holes 5.
[0019] A gravel layer is placed at the bottom of groove 3, above the through hole 5. The gudgeon prefers to lay its eggs in sandy soil; the gravel layer simulates this preferred spawning environment, attracting the gudgeon to spawn. The gravels in the gravel layer are larger than the diameter of through hole 5, with gaps between them. When laying eggs, the gudgeon uses its tail to sweep away the gravel, exposing through hole 5. The eggs then fall through through hole 5 into collection box 1, thus completing the collection. This also prevents the eggs from being eaten by other fish.
[0020] The separation frame 2 includes an extension plate 6 located at the outer edge, which is positioned at the upper end of the collection box 1, so that the separation frame 2 rests on the collection box 1.
[0021] Furthermore, an inclined surface 4 is provided on the side of the groove 3, with the upper end of the inclined surface 4 being closer to the outer periphery of the separation frame 2 than the lower end of the inclined surface 4. The inclined surface 4 is inclined to guide the light-lipped fish to the bottom of the groove 3 to lay eggs, reducing the occurrence of light-lipped fish laying eggs at the inclined surface 4.
[0022] Furthermore, a sealing block 13 is connected to the lower part of the extension plate 6. The inner wall of the sealing block 13 is fitted to the outer wall of the collection box 1. A locking block 14 is provided on the outer wall of the collection box 1. A locking groove 15 is opened on the inner wall of the sealing block 13 to cooperate with the locking block 14. The locking block 14 can be locked into the locking groove 15, thereby fixing the sealing block 13 and the collection box 1. Through the cooperation of the sealing block 13 and the collection box 1, the gap between the collection box 1 and the separation frame 2 can be effectively sealed, thereby preventing the light-lipped fish from entering the collection box 1 through the gap between the two and swallowing the fish eggs.
[0023] Furthermore, an egg-collecting frame 9 is provided inside the collection box 1, located below the bottom of the separation frame 2. A support block 8 is provided on the inner wall of the collection box 1, and the egg-collecting frame 9 is mounted on the support block 8. A filter screen 10 is installed at the bottom of the egg-collecting frame 9, and the aperture of the filter holes on the filter screen 10 is smaller than the particle size of the fish eggs. A guide surface 11 is provided at the bottom of the egg-collecting frame 9, and the guide surface 11 is inclined. Fish eggs falling through the through holes 5 fall into the egg-collecting frame 9 for collection. The filter screen 10 can filter fish feces, sand, etc., entering the egg-collecting frame 9, reducing impurities mixed with the fish eggs.
[0024] Furthermore, the upper part of the support block 8 is provided with an insert block 12, and the bottom of the egg collection frame 9 is provided with an installation groove that cooperates with the insert block 12. The egg collection frame 9 is fixedly installed on the support block 8 through the cooperation of the installation groove and the insert block 12.
[0025] Furthermore, a lifting ring 7 is installed on the upper part of the extension plate 6. A lifting rope can be connected to the lifting ring 7. When collecting fish eggs, the collection box 1 and the separation frame 2 can be pulled out of the fish pond by the lifting rope, eliminating the need for staff to enter the fish pond to retrieve them and reducing the amount of equipment.
[0026] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
