Description

Technical Field

[0001] This utility model particularly relates to a shrimp breeding and hatching system. Background Technology

[0002] In the farming of red swamp crayfish (such as Australian freshwater crayfish), the larvae have already reached adult form upon hatching and are called "juveniles" or "larvae." Mothers and larvae are usually raised together, but the larvae are small and easily eaten or crushed by the mothers, leading to a lower survival rate. Traditional manual sorting methods are inefficient and prone to damaging the larvae. Therefore, there is an urgent need for a shrimp rearing and hatching system that can automatically separate larvae from mothers to improve larvae survival rates and farming efficiency.

[0024] A shrimp breeding and hatching system, referring to Figures 1-2 The system includes a shell 1, on which a culture trough for accommodating female shrimp and shrimp larvae is provided. The culture trough is divided into a transition zone 21 and a culture zone 22. An incubation box 3 is provided on the shell 1 for incubating female shrimp and shrimp larvae. Multiple separation holes 4 are provided on the bottom of the incubation box 3. The diameter of the separation holes 4 is smaller than the size of the female shrimp but larger than the size of the shrimp larvae so that the shrimp larvae can fall into the transition zone 21. A water circulation device is connected to the shell 1, which can flush the shrimp larvae in the transition zone 21 into the culture zone 22.

[0025] Furthermore, the water circulation device includes an inlet pipe 51 connected to the transition zone 21 and an outlet pipe 52 connected to the aquaculture zone 22. A water supply pipe 53 is connected to the hatching box 3. The water supply pipe 53, the inlet pipe 51, and the outlet pipe 52 are all connected to a water tank 54. A water pump is installed on the water tank 54 to pump water from the aquaculture zone 22 to the water tank 54. A shrimp larvae escape prevention net 521 is installed at the installation port of the outlet pipe 52 in the aquaculture zone 22.

[0026] Furthermore, an oxygen supply device is installed in the breeding area 22.

[0027] Furthermore, the bottom of the transition zone 21 is inclined downwards.

[0028] Furthermore, the bottom of the incubator 3 is provided with a base plate 31 for opening separation holes 4.

[0029] Furthermore, the base plate 31 is installed inside the incubator 3 via a detachable structure.

[0030] Furthermore, the detachable structure is a snap-fit ​​connection.

[0031] Furthermore, the separation hole 4 is circular or elongated, with a diameter of 2-5 mm.

[0032] Furthermore, the shrimp larvae escape prevention net 521 is a nylon net.

[0033] The working principle of this utility model is as follows:

[0034] Firstly, the incubator 3 is used to incubate shrimp larvae. After incubation, the incubator 3 contains both the mother shrimp and the larvae. The incubator 3 needs water, as the mother shrimp and larvae rely on water for respiration and development. This application provides a separation hole 4 at the bottom of the incubator 3. The diameter of the separation hole 4 is larger than that of the larvae but smaller than that of the mother shrimp. The larvae and mother shrimp can move freely in the incubator 3. The water in the incubator 3 will fall into the transition zone 21 of the rearing tank through the separation hole 4. Since the size of the larvae is smaller than the diameter of the separation hole 4, the larvae will fall from the incubator 3 into the transition zone 21, achieving automatic separation of the larvae and mother shrimp. Then, the water circulation device uses water to flush the larvae in the transition zone 21 into the rearing zone 22. This design can achieve automatic separation of the larvae and mother shrimp, reduce manual sorting costs, and thus prevent the mother shrimp from feeding on or squeezing the larvae, improving the survival rate of the larvae.

[0035] Based on the above technical solution, this application provides a bottom plate 31 for opening separation holes 4 on the bottom of the incubator 3. The bottom plate 31 can be detachably installed from the incubator 3, and the installation method can be a snap-fit ​​connection. This design allows for the selection of the corresponding bottom plate 31 for the separation hole 4 according to different types of shrimp larvae, thus improving practicality. As a preferred solution, the separation hole 4 can be set to be circular or elongated to allow shrimp larvae to pass through while blocking the mother shrimp. The hole diameter can be set to 2-5mm.

[0036] Based on the above technical solution, if the aquaculture area 22 is used as a place for long-term aquaculture, an oxygen supply device can be installed in the aquaculture area 22 to provide oxygen and ensure the survival environment of shrimp larvae. The oxygen supply device is a conventional technical means of this technology, so its working principle will not be described in detail in this article.

[0037] Based on the above technical solution, regarding the design and coordination of the water circulation device, an inlet pipe 51 is connected to the transition zone 21, an outlet pipe 52 is installed in the breeding zone 22, and a supply pipe 53 is connected to the hatching box 3. The supply pipe 53, the inlet pipe 51, and the outlet pipe 52 are all connected to a water tank 54. The water tank 54 can be placed above the shell 1, and gravity will draw the water in the water tank 54 into the inlet pipe 51 and the supply pipe 53. The water in the supply pipe 53 is used to provide water for the shrimp larvae and mother shrimp to maintain their breathing and development. The water in the inlet pipe 51 flows into the transition zone 21, flushing the shrimp larvae in the transition zone 21 into the breeding zone 22 (in this solution, a water pump can also be used to pump water in). The incubation box 3 and the transition zone 21 are provided. As a preferred option, the bottom of the transition zone 21 can be designed to slope downwards and extend to the breeding zone 22. This design can prevent shrimp larvae from flowing back into the transition zone 21. A water outlet pipe 52 is connected in the breeding zone 22, and a water pump is used to pump part of the water in the breeding zone 22 to the water tank 54 to realize the recycling of water resources. It is worth noting that when the water in the breeding zone 22 is pumped to the water tank 54, in order to prevent the shrimp larvae from being pumped into the water tank 54 as well, a shrimp larvae escape prevention net 521 needs to be installed at the installation port of the water outlet pipe 52 in the breeding zone 22. As an example, the shrimp larvae escape prevention net 521 can be made of nylon mesh.

[0038] In the shrimp hatching system of this application, shrimp larvae fall into the transition zone 21 of the breeding tank through the separation hole 4, realizing the automatic separation of shrimp larvae and mother shrimp. Then, the water circulation device uses water to flush the shrimp larvae in the transition zone 21 into the breeding zone 22. This design can realize the automatic separation of shrimp larvae and mother shrimp, reduce the cost of manual sorting, thereby avoiding the mother shrimp feeding on or squeezing the shrimp larvae and improving the survival rate of shrimp larvae.

[0039] Although the present invention has been described in detail with reference to the above embodiments, it will be apparent to those skilled in the art that various changes or modifications can be made to the present invention without departing from the principles and spirit of the present invention as defined by the claims. Therefore, the detailed description of the embodiments in this disclosure is for explanation only and not for limiting the present invention, but rather the scope of protection is defined by the content of the claims.
