Description

Technical Field

[0001] This invention relates to the field of aquaculture technology, and in particular to a mandarin fish farming pond and feeding method. Background Technology

[0002] Mandarin fish (also known as osmanthus fish or mandarin perch) is one of my country's four famous fish. It is highly favored by consumers for its tender flesh, delicious taste, and health benefits, including strengthening the spleen and stomach, replenishing qi, beautifying the skin, and promoting lactation. Therefore, the increasing consumer demand has spurred people to seek artificial breeding methods, and the technology for artificially breeding mandarin fish urgently needs to be developed and promoted.

[0003] Mandarin fish have unique habits; they prefer to prey on live, swimming fish and dislike eating stationary food. Therefore, in artificial breeding of mandarin fish, long, strip-shaped feed similar to small fish is used. After being added, the feed floats on the surface of the pond (floating feed). Water needs to be sprayed onto the surface to make the feed float, mimicking the movement of live fish and thus enticing the mandarin fish to feed, satisfying their feeding habits. However, this method is complex, labor-intensive, and unsuitable for large-scale factory production (large-scale factory farming involves many ponds, and feeding takes too long). Furthermore, because mandarin fish require flowing water, the feed on the surface is easily washed out of the pond by the current. Summary of the Invention

[0004] In view of the problems existing in the prior art, the present invention aims to provide a mandarin fish breeding pond and feeding method that can simulate the feeding environment of mandarin fish and prevent the feed from being washed away by the water flow.

[0005] To achieve the above objectives, this invention proposes a mandarin fish farming pond, comprising a pond body, a water distribution pipe, and a water supply pipe. The water distribution pipe floats on the water surface inside the pond body and is positioned near the pond edge. One end of the pipe is horizontally hinged to the side wall of the pond body, while the other end is a free end and closed. A pull rope is connected to the free end of the water distribution pipe. The pull rope floats on the water surface inside the pond body, and the other end of the pull rope extends towards a side opposite to the rotation direction of the water distribution pipe and is fixed to the side wall of the pond body. The pull rope has sufficient length to allow the water distribution pipe to rotate. The pull rope rotates to open... The water distribution pipe and the side wall of the pool cooperate to form a feeding ring on the water surface. The side of the water distribution pipe facing the feeding ring has water distribution holes. On the opposite side walls of the pool, there are water inlets and outlets respectively. The water inlet is located at the bottom of the side wall of the pool, and the water outlet is located at the top of the other side wall of the pool, flush with the water surface and outside the feeding ring. The water inlet and outlet cooperate to make the water inside the pool flow, making it running water. The water supply pipe is divided into two branches, which are connected to the hinged end of the water distribution pipe and the water inlet of the pool respectively. Both branches are equipped with valves.

[0006] In the above scheme, the fixing point of the pull rope and the hinge point of the water distribution pipe are located at two adjacent corners of the pool body, which is convenient to set up and can form a relatively large feeding circle.

[0007] In the above solution: a cylinder is provided between the water distribution pipe and the side wall of the pool. The cylinder can drive the water distribution pipe to rotate around the hinge point, realizing automated drive, convenient operation, and saving manpower.

[0008] In the above scheme: a row of water distribution holes is provided along the length of the water distribution pipe, which is beneficial to expand the area of ​​the water spraying area, thereby enabling the feed to float relatively evenly in various places.

[0009] In the above scheme: one branch of the water supply pipe passes over the side wall of the pool from above and is connected to the hinged end of the water distribution pipe.

[0010] In the above scheme: the water supply pipe is divided into two branch pipes with valves through a three-way valve, which is convenient to connect.

[0011] This invention also proposes a feeding method for mandarin fish. First, the water distribution pipe is rotated open so that the water distribution pipe, the pull rope, and the side wall of the pool form a feeding circle on the water surface. Then, feed is added into the feeding circle. Next, the valve of the corresponding branch pipe of the water distribution pipe is opened so that the water distribution pipe sprays water onto the pool surface, causing the feed to float to simulate the movement of live fish. After feeding, the water distribution pipe is retracted to the edge of the pool.

[0012] The beneficial effects of this invention are:

[0013] Before feeding, the water distribution pipe is rotated to the center of the pond (either manually or with an automatic drive device such as a cylinder), opening it away from the edge. This allows the pipe, rope, and pond sidewall to form a feeding circle on the water surface. Floating feed is then added to this circle to prevent it from being washed away by the water flow. Next, the valves on the corresponding branch pipes of the water distribution pipe are opened, spraying water onto the pond surface. This causes the feed to float, mimicking the movement of live fish and enticing the mandarin fish to feed. The water distribution pipe effectively expands the spray area, ensuring relatively even feeding. After use, the pipe can be retracted to the pond edge to avoid interfering with the mandarin fish's activity. In summary, this invention is simple in structure, easy to operate, and has low breeding costs, making it suitable for large-scale aquaculture farms and preventing feed from being washed away by the water flow.

[0016] Figure 3 This is a schematic diagram of the internal structure of the pool in this invention (with the water distribution pipe rotated and open). Detailed Implementation

[0017] like Figure 1 As shown in Figure 3, a mandarin fish farming pond mainly consists of a pond body 1, a water distribution pipe 2, and a water supply pipe 3.

[0018] The water distribution pipe 2 floats on the water surface inside the pool body 1 and is located near the edge of the pool. One end of the pipe is horizontally hinged to the side wall of the pool body 1, and the other end is a free end and is closed. A pull rope 4 is connected to the free end of the water distribution pipe 2. The pull rope 4 floats on the water surface inside the pool body 1, and the other end of the pull rope 4 extends to the side opposite to the rotation direction of the water distribution pipe 2 and is fixed to the side wall of the pool body 1. The pull rope 4 has sufficient length to allow the water distribution pipe 2 to rotate.

[0019] A cylinder 7 is installed between the water distribution pipe 2 and the side wall of the pool body 1. The cylinder 7 can drive the water distribution pipe 2 to rotate around the hinge point, realizing automatic drive, convenient operation, and saving manpower. Alternatively, the cylinder 7 can be omitted in the pool body 1, and the water distribution pipe 2 can be rotated manually.

[0020] The pull rope 4, the rotating and opened water distribution pipe 2, and the side wall of the pool body 1 work together to form a feeding circle A on the water surface. Water distribution holes are provided on the side of the water distribution pipe 2 facing the feeding circle A. Specifically, a row of water distribution holes can be arranged along the length of the water distribution pipe 2, which helps to expand the spray area and thus more evenly move the feed to float. The fixing point of the pull rope 4 and the hinge point of the water distribution pipe 2 are located at two adjacent corners of the pool body 1, which is convenient for installation and can form a relatively large feeding circle A.

[0021] Water inlet 5 and water outlet 6 are respectively provided on the two opposite side walls of pool body 1. Water inlet 5 is located at the bottom of the side wall of pool body 1, and water outlet 6 is located at the top of the other side wall of pool body 1, flush with the water surface, and located outside the feeding ring A.

[0022] The inlet 5 and outlet 6 work together to allow the water inside the pool 1 to flow, making it a flowing system. The water supply pipe 3 branches into two branches, which are respectively connected to the hinged end of the distribution pipe 2 and the inlet 5 of the pool 1. Both branches are equipped with valves. Specifically, the water supply pipe 3 branches into two branches with valves through a three-way valve. One of the branches of the water supply pipe 3 passes over the side wall of the pool 1 from above and connects to the hinged end of the distribution pipe 2.

[0023] A method for feeding mandarin fish involves first rotating and opening the water distribution pipe 2, so that the water distribution pipe 2, the pull rope 4, and the side wall of the pool 1 cooperate to form a feeding circle A on the water surface; then, feed is added into the feeding circle A to prevent the feed from being washed away by the water flow; then, the valves of the corresponding branch pipes of the water distribution pipe 2 are opened, allowing the water distribution pipe 2 to spray water onto the pool surface, causing the feed to float to simulate the movement of live fish, thereby attracting the mandarin fish to feed; after feeding, the water distribution pipe 2 is retracted to the edge of the pool.
