Description

Technical Field

[0001] The utility model relates to the technical field of aquaculture, in particular to a large-scale hatching system for blackspined barbel eggs. Background Art

[0002] Black-backed spiny barb ( spinibarbuscaldwelli ), also known as spiny barb, belongs to the Cypriniformes, Cyprinidae, Barbinae, and the genus Spinulina. Spinibarbus ), commonly known as light fish, army fish, etc., often like to live in streams and rivers with fast currents, clear water and more gravels, and are middle and lower layer fish. Black-backed spiny barb has a variety of diets, is cold-resistant, has strong disease resistance, has a beautiful body shape, delicate meat, and delicious taste. Its scales are large and edible. The fish soup is refreshing, heat-relief, and detoxification. The eggs can be soaked in hot water for external application to stop bleeding. It has the advantages of food and medicinal effects. It has long been loved by consumers and is a famous freshwater variety with broad market prospects.

[0003] At present, the artificial hatching of black-backed spiny barb still uses traditional cement pools, hatching rings, hatching barrels or tanks for hatching. However, this traditional "house fish"-style hatching facility is mostly built with materials such as cement, steel bars, bricks, etc., with high construction costs, large floor space, difficulty in moving, and complex and clumsy operation of the hatching process. The fertilized eggs of black-backed spiny barb are sinking eggs with large egg grains. When hatching with traditional hatching facilities, a large amount of flushing and aeration are required to keep the fertilized eggs in suspension and high dissolved oxygen hatching state, which consumes resources such as water and electricity, and the hatching state of the fertilized eggs is difficult to track and observe, and necrotic eggs are not easy to remove during the hatching process. In addition, the black-backed spiny barb that has just hatched out of the membrane needs to be left at the bottom of the water for 3-5 days before it can swim horizontally. If there are necrotic eggs in the hatching pool at this time, the hatching rate will be low, which will affect the efficiency of seedling production. Utility Model Content

[0004] In view of this, the purpose of the utility model is to provide a large-scale hatching system for black-spine spiny barb eggs, which is convenient and practical, reduces production costs and energy consumption, facilitates tracking and observation and removal of necrotic eggs, and improves the hatching rate.

[0005] The utility model adopts the following scheme to achieve: a large-scale hatching system for black-spine spiny barb eggs, comprising a circular hatching pool, wherein the hatching pool is provided with a ring-shaped anti-escape ring floating on the water surface, and a plurality of hatching baskets surrounded in a circle and suspended on the water surface are provided in the ring-shaped area formed between the anti-escape ring and the inner wall of the hatching pool.

[0006] Furthermore, a water inlet pipe is provided above the side wall of the hatching pool, an overflow pipe is provided on the upper part of the outer side wall of the hatching pool, a drain pipe is provided at the bottom of the hatching pool, and the overflow pipe is connected to the drain pipe through a connecting pipe.

[0007] Furthermore, an aeration plate is provided in the hatching pool, and the aeration plate is connected to the air supply pipe a; each hatching basket is provided with an air stone, and the air stone is connected to the air supply pipe b.

[0008] Furthermore, the hatching basket is in the shape of a circular trough, and includes a hatching basket frame and a mesh wrapped around the bottom and four sides of the hatching basket. The hatching basket frame is composed of an upper support ring, a lower support ring and a plurality of support rods connecting the upper and lower support rings. An annular foam ring is fixedly connected to the upper support ring by a fixing tie.

[0009] Compared with the prior art, the utility model has the following beneficial effects:

[0010] (1) Low construction cost, small footprint, high utilization efficiency, can realize intensive and large-scale production, flexible and convenient collection and use, and reduce labor intensity;

[0011] (2) Compared with traditional black-backed spiny barb hatching facilities, the use of water, electricity and gas is greatly reduced, which can achieve water-saving and electricity-saving hatching, reduce the waste of water and electricity resources, and reduce production energy consumption;

[0012] (3) It is easy to operate and manage, and is convenient for observing the hatching status of fertilized eggs and recording and statistics of data. It can not only meet production needs, but also provide personalized services for scientific research experiments;

[0013] (4) It is convenient to remove necrotic eggs and collect seedlings, and there is no dead corner for hatching, which improves the hatching efficiency; the hatching basket is suspended on the water surface and will automatically float up and down according to the water level, reducing the impact of human operating errors on the hatching rate and germination rate.
