Description

Technical Field

[0001] This utility model relates to the technical field of artificial breeding and hatching equipment for fish, specifically a hatching device for loach. Background Technology

[0002] With the development of aquaculture and the needs of scientific research, various fish hatching devices are widely used in the industry. Currently, fish hatching facilities are mainly made of sheet metal, fiberglass, polypropylene, stainless steel, glass, acrylic, and even concrete, which have drawbacks such as being prone to rusting, having weak UV resistance, being susceptible to corrosion, being fragile, and having a certain degree of toxicity to fish eggs.

[0003] The farming of loaches generally involves the female loach laying eggs, which are then transferred to incubation tanks and hatched into fry under suitable temperature and conditions. Ordinary incubation devices not only have problems such as being labor-intensive and time-consuming to build, being bulky and complicated to manufacture, but also have drawbacks such as being inconvenient to move, consuming a lot of water, and being difficult to operate. In addition, it is difficult to control the flow rate of the incubation water when using existing ordinary incubation devices.

[0004] A search revealed a patent document with application number 202020694799.X (authorization announcement number CN212573883U), which discloses a fish fry incubator. While it can meet the incubation requirements for fish eggs, it has the following main shortcomings: First, the device has a complex structure with as many as 21 structural components; second, the components are not standardized, making them difficult to manufacture (e.g., hooks, spring baffles, sliding grooves, placement grooves, limiting balls, cylinders, etc.); third, the device has a high production cost, due to the addition of a fixed support frame and multiple cylinders, and it is difficult to maintain, as the structure between the support frame and the sliding groove, placement groove, limiting ball, and limiting groove is prone to damage.

[0005] Patent application number 201520371913.4 (authorization announcement number CN204742203U) discloses a spiny loach hatching tank. This hatching tank can avoid damage to the spiny loach eggs caused by the impact of water flow. However, in use, it has the following main shortcomings: First, it does not have a pH and temperature adjustment device, so the pH detection device and thermometer are only for detection and have no practical use; second, the hatching device does not mention any structure related to oxygen replenishment, making it difficult to meet the oxygen demand during the hatching period of fish eggs; third, the hatching net does not have a clear mesh size, which cannot be adapted to fish eggs and hatched fry of different sizes, causing fish eggs and fry to overflow from the net due to excessively large mesh or obstructing water exchange due to excessively small mesh.

[0006] Patent application number 201320016996.6 (authorization announcement number CN203087267U) discloses a fish hatching device. The hatching tank is made of silk gauze. When the fish fry hatch and need to be transferred, the water can be quickly drained from the pool for rapid collection and transfer. However, the main problem in use is that because the hatching tank is made of silk gauze, a pool is required, making it inconvenient to use.

[0007] The three patent documents retrieved disclose incubation devices for fish hatching from different perspectives. However, since most loaches are small, sub-cold-water fish, they typically do not require large-volume hatching facilities but have high dissolved oxygen requirements. In practical use, existing hatching facilities are not suitable for hatching smaller fish such as loaches. Therefore, there is an urgent need to develop a dedicated hatching device for loaches to meet their hatching needs. Utility Model Content

Example 2

[0039] like Figure 2 As shown, this embodiment is based on embodiment 1. In order to facilitate cleaning, transportation and installation, a loach hatching device provided in this embodiment is adopted.

Simultaneously, the connecting hose 23 is passed through the gauze 31 and placed inside the hatching tank 21. The hatching water is supplied by an external water source connected to the water pump 11 in the water inlet system 1, and injected into the hatching tank 21 through the water inlet pipe 16. A water flow regulating valve 19 is installed in the water inlet pipe 16 to adjust the water flow and volume, allowing the fish eggs to float inside the hatching tank 21. Simultaneously, the electric oxygenator 22 is turned on, continuously supplying oxygen to the fish eggs through the connecting hose 23.

The water flow and water volume are regulated by the water flow regulating valve 19 in the water inlet pipe 16, so that the fish eggs float in the hatching tank 21. This can effectively avoid the problem of water flow impacting the loach fish eggs and causing damage. A filter system 3 is provided at the top of the hatching tank 21, and the gauze 31 can prevent the fish eggs and hatched fry from overflowing and escaping.

[0044] In summary, the incubation device described in this utility model effectively solves the shortcomings of traditional fish incubators, such as excessive size, cumbersome structure, and difficulty in cleaning and transportation.
