Description

Technical Field

[0001] The utility model relates to the technical field of aquaculture equipment, in particular to a fish nest used for inducing fish to spawn in a spawning pond. Background Art

[0002] With the continuous development of aquaculture production in my country, the number of fish nests required for carp, crucian carp and other fish that lay sticky eggs has increased as the production of seedlings increases. However, with the changes in the natural environment, it is difficult to find enough natural fish nests such as willow roots and red root grass. Therefore, the rise of artificial fish nests has become an indispensable adhesion matrix for the development of aquaculture production. They are usually made of polyethylene mesh, straw bales, plastic wire and other materials.

[0003] However, in order to improve the hatching rate and emergence rate of fry during production and facilitate operation and sales, hatchery farms usually use hatching rings to hatch fertilized eggs. The artificial fish nests made of the above materials are more suitable for pond hatching or cage hatching. However, such hatching methods are cumbersome to operate when collecting fry, especially the fry hatched in ponds must grow to black fry (1.2 to 1.5 cm) before they can be netted and sold. Therefore, it is urgent to design an artificial fish nest that is convenient for collecting fertilized eggs and can be reused. Utility Model Content

[0004] In view of the above technical problems, the utility model provides a fish nest for inducing fish spawning in an induced spawning pool, which is characterized by comprising a wall of the induced spawning pool, a fixing ring, a connecting rope, a fish nest, a gravity block, and a float. A plurality of fixing rings are installed on the wall of the induced spawning pool at both sides in an interval arrangement, a connecting rope is connected through the plurality of fixing rings, and the two connecting ropes are respectively connected to the two end ends of the fish nest, and gravity blocks are respectively arranged at both ends of the fish nest, and a plurality of floats are installed on the fish nest in an evenly spaced arrangement.

[0005] The fish nest is composed of an installation rope and a wool bundle, two ends of the installation rope are respectively connected to a fixing ring, and a plurality of wool bundles are arranged and connected at intervals on the installation rope.

[0006] Specifically, the wool bundle is made by bundling a plurality of acrylic wool yarns.

[0007] Specifically, the connecting rope and the installation rope are both made of polyethylene rope.

[0008] Beneficial effects of the utility model:

[0009] The utility model has a simple overall structure, and the fish nest is pulled to the side of the spawning pool by pulling the connecting rope to collect the fish eggs on the fish nest, which is convenient for the fish egg collection operation;

[0010] The utility model adopts acrylic yarn as an artificial material to bundle and make the fish nest, which is convenient to obtain materials, low in cost, simple to make, good inducing effect and easy to clean;

[0011] The spawning pond uses fish nests made of acrylic wool, which are not easy to stick to fish eggs. There is no need to replace the fish nests during the spawning process of the broodstock, reducing the impact of replacing the fish nests on the spawning of the broodstock. The eggs adhered to the wool can fall off after being flushed by the concentrated water flow, which is conducive to collecting the fertilized eggs and putting them into the hatching ring for centralized hatching, which is easy to manage and avoids the complicated management of the fish nests after they are put into the pond.

[0017] Example 1

[0018] As shown in the figure, a plurality of fixing rings 1 are installed at equal intervals on the wall 6 of the induced labor pool. The fixing rings 1 are connected through with connecting ropes 7 made of polyethylene rope material and are used to connect the fish nest. The fish nest is composed of a plurality of wool bundles 4 arranged at equal intervals and bolted together by mounting ropes 2 made of polyethylene rope. The wool bundles 4 are formed by bundling a plurality of acrylic yarns. The gravity blocks 3 are arranged and connected at both ends of the fish nest. The floats 5 are connected to the fish nest with gaps.

[0019] The diameter of the fixing ring 1 is about 1 to 1.5 cm, and it is embedded in the wall 6 of the oxytocin pool on both sides. The interval between adjacent fixing rings 1 is about 1.2 meters. The fixing ring 1 is connected by a connecting rope 7 made of a polyethylene rope with a diameter of 3 to 5 mm, and is fastened to the fixing rings 1 at both ends of the wall 6 of the oxytocin pool. The connecting rope 7 is used to connect the fish nest;

[0020] The yarn bundle 4 on the fish nest is made of light green acrylic yarn, the yarn is 50 cm long, and each 30 to 35 yarns form a bundle, and a 5 cm wide plastic is used to roll up the middle of the yarn. After each 4 bundles of yarn are crossed, they are tied tightly from the middle with a polyethylene rope with a diameter of 1 mm and then bolted to a polyethylene rope with a diameter of 3 mm. Usually, the interval between adjacent yarn bundles 4 is 25 cm, and the length of each fish nest is determined according to the specifications of the induced spawning pool;

[0021] The gravity block 3 is bolted to both sides of the fish nest to prevent the yarn bundle 4 near the spawning pool from being pulled out of the water surface due to the pulling force. The gravity block 3 is usually 20 to 30 cm away from the yarn bundle on both sides of the fish nest.

[0022] The float 5 is arranged in intervals and bolted to the fish nest. The float 5 and the fish nest are connected with a rope of 15 to 20 centimeters in length. The number of ropes used is adjusted according to the length of the fish nest and the sinking of the fish nest after entering the water.

[0023] When the utility model is in use, the length of the entire fish nest is determined according to the specifications of the induced spawning pool, the fish nest is formed by bolting a woolen bundle 4 through an installation rope 2 made of a polyethylene rope, both ends of the fish nest are connected to a connecting rope 7 that passes through a fixed ring 1, and the number of fish nests can be adjusted according to the induced spawning specifications and the number of parent fish. When the parent fish finish spawning, the fish nest is taken out, and the fish nest is flushed with a concentrated water flow to flush the fertilized eggs adhered to the woolen thread and fall off, and then collected and put into an incubation ring for centralized incubation. The fish nest can be used again after being cleaned and aired.

[0024] 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.
