Description

Technical Field

[0001] The utility model belongs to the field of fishery breeding, and in particular relates to an auxiliary tool for collecting sticky eggs of carp and crucian carp in a spawning pond. Background Art

[0002] In the artificial breeding of freshwater fish, such as carp, crucian carp, bream and other sticky fish eggs, the most commonly used method is to use the method of attaching fish eggs to fish nests for hatching, but there are shortcomings such as unstable hatching effect, difficult to master the production, erection, management and number of fish fry, which cannot meet the needs of industrialized production; if the worker debonding technology is used, artificial fertilization technology must be used, and yellow mud slurry, talcum powder and salt solution must be used for debonding. Not only will a thick layer of debonding material adhere to the outside of the egg membrane, which will affect the physiological activities such as breathing and metabolism of the fertilized eggs and reduce the hatching rate, but it is also time-consuming, labor-intensive, and complicated to operate, and it cannot form large-scale production. The natural debonding technology of carp and crucian carp eggs is a way of industrialized production, but the fertilized eggs that have lost their stickiness but are still slightly attached to the bottom of the pond can only be separated by brooms or with the help of water flow impact, and brooms are relatively rough and will cause damage to the fertilized eggs. Using water flow impact will not only waste hatching water but also damage the fertilized eggs.

[0003] How to quickly and efficiently collect the fertilized eggs adhering to the bottom of the spawning pond into the egg collection box without causing any damage to the fertilized eggs, saving time and effort, and saving water resources is the key to the industrialization needs of carp and crucian carp. After years of continuous exploration and practice, the applicant has innovatively developed an auxiliary tool for collecting fertilized eggs at the bottom of the spawning pond of carp and crucian carp. Utility Model Content

[0004] The utility model provides an auxiliary tool for quickly and efficiently collecting fertilized eggs of carp and crucian carp in a spawning pond to solve the technical problems existing in the known technology. The tool can effectively solve the problem that the fertilized eggs of carp and crucian carp adhere to the bottom of the spawning pond and cannot be separated after the natural spawning of carp and crucian carp, and provides technical support for realizing large-scale induced spawning of carp and crucian carp.

[0005] In order to solve the above technical problems, the utility model is solved by the following technical solutions:

[0006] An auxiliary tool for quickly and efficiently collecting fertilized eggs of carp and crucian carp in a spawning pond, characterized in that the auxiliary tool is similar to a large shovel, including a shovel head and a shovel handle, the shovel head is rectangular, the front end of the shovel head is a flat-mouthed inclined surface, the tail end of the shovel head extends toward the shovel head and rolls vertically downward to form a groove, the tail end of the shovel head is connected to the shovel handle, and the top of the shovel handle is a round spherical shape.

[0007] The shovel head is cast from stainless steel and has a thickness of 0.12 cm to 0.15 cm.

[0008] The shovel head is 40 cm long and 16 cm high.

[0009] The front end of the shovel head is a bevel with a width of 0.1 cm and a thickness of 0.1 cm. The shovel head is smooth all around.

[0010] The shovel handle is made of a steel pipe and has a length of 1.3 m.

[0011] When the utility model is used, the large shovel is tilted at an angle of 45 degrees along the bottom of the spawning pool, and is gently pushed forward in the water body to separate the fertilized eggs adhered to the bottom of the spawning pool and drift forward with the water flow.

[0012] The beneficial effects of the utility model include: an auxiliary tool for collecting sticky eggs in a spawning pond. The utility model, by combining the existing technology, does not need to use the impact of water flow and other tools. Four hours after the spawning of parent fish, 2 to 4 workers are arranged side by side in the spawning pond from the outer edge of the spawning pond, each holding a large shovel and moving forward along the bottom of the pond at an angle of 45 degrees in one direction to shovel away the fertilized eggs on the bottom of the pond. At the same time, the pushed water flow drives the fertilized eggs to drift to the dark pipe in the middle of the spawning pond, and flows into the egg collecting box with the drop. Since the shovel head of the large shovel is smooth and delicate and the bottom of the spawning pond is polished with terrazzo, the fertilized eggs will not be damaged. The whole operation is convenient and fast, saving time, labor and water. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] Example 1

[0020] See Figure 1 A large shovel used for quickly and efficiently collecting fertilized eggs of carp and crucian carp in spawning ponds, comprising a shovel head 1 and a shovel handle 2 connected to the shovel head, the shovel head is rectangular, 40 cm long and 16 cm wide, the front end 3 of the shovel head is a beveled flat mouth, the rear end 4 of the shovel head extends 3.2 cm upward and extends 2 cm parallel to form a groove, the rear end 4 of the shovel head is welded to the shovel handle 2, and the top of the shovel handle 2 is a round spherical shape 5.

[0021] The broodstock to be laid are placed in a spawning pond with a smooth surface and terrazzo at the bottom. 4 hours after the broodstock finish spawning, the water level of the spawning pond is lowered. When the water level drops to 20 cm, 2 to 4 staff members stand side by side in the spawning pond, tilt a large shovel at a 45-degree angle, and use the flat grinding surface of the shovel head to gently shovel away the fertilized eggs adhering to the bottom of the spawning pond along the bottom of the spawning pond in one direction. During the process of pushing the large shovel forward, the groove above the shovel head invisibly blocks the water flow and the circuit of free fertilized eggs. At the same time, the round shape of the shovel handle can be held in one hand without bending over, and the fertilized eggs can be pushed forward together with the pond water. The fertilized eggs drift forward and form a circulation. With the difference in terrain between the spawning pond and the egg collecting pond, the fertilized eggs gather in the center of the spawning pond with the water flow, and enter the egg collecting box through the concealed pipe. The fertilized eggs can be collected without flushing.

[0022] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. The various components mentioned in the utility model are common technologies in the existing field. The technicians in this industry should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only to illustrate the principles of the utility model. Without departing from the spirit and scope of the utility model, the utility model will have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection claimed by the utility model is defined by the attached claims and their equivalents.
