Abstract
Description
Technical Field
[0001] This utility model relates to the field of red swamp crayfish farming technology, and in particular to a device for incubating eggs of red swamp crayfish. Background Technology
[0002] The red swamp crayfish, commonly known as the crayfish, has seen its farming scale expand rapidly in recent years due to the surge in demand from the catering industry. In red swamp crayfish farming, the egg-bearing incubation stage is crucial, directly affecting the yield and quality of the crayfish larvae, and consequently impacting the overall profitability of the aquaculture industry.
[0003] Traditional swamp swamp crayfish (Procambarus clarkii) egg-carrying and hatching methods have numerous problems. In wild ponds, female broodstock typically lay, carry, and hatch their eggs in burrows. The unstable temperature in these burrows slows hatching, and the asynchronous development of the gonads and eggs results in inconsistent shrimp larvae size. Furthermore, the common practice of mixing shrimp of different sizes in the same pond leads to cannibalism of smaller and soft-shelled shrimp, resulting in extremely low larval rates and a persistent shortage of high-quality seedlings.
[0004] Looking at traditional cement pond hatching, although aquatic plants, nets, bricks, tiles, and PVC pipes are used as hiding places, their drawbacks are also obvious. After mid-October, the temperature drops, and the aquatic plants in the cement pond are prone to die and rot, thus deteriorating the water quality; using bricks and tiles as hiding places, uneaten food and excrement easily accumulate, making cleaning difficult, and turning them over during inspection can easily injure berried shrimp and shrimp larvae; PVC pipes have poor stability and are prone to rolling, which may cause berried shrimp to lose their eggs; the placement of nets is not flexible and cannot well meet the hatching needs of berried shrimp.
[0005] To solve the above problems, it is urgent to design a new type of incubation device for red swamp crayfish. Utility Model Content

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0027] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0028] Example 1:
[0029] Reference Figure 1 This utility model provides a device for hatching eggs of the red swamp crayfish, including...
[0030] A water storage tank 1 is provided with an inlet pipe 2 at the top of the water storage tank 1 and a water pump 3 is fixedly connected to the bottom of the water storage tank 1. The water pump 3 is connected to the inlet pipe 2.
[0031] Install pipe 4, which is fixedly installed in water storage tank 1. Install pipe 4 is set horizontally and several egg-bearing incubation containers 5 are inserted into the installation pipe 4. One end of the installation pipe 4 is connected to the water inlet pipe 2 through a connecting pipe.
[0032] Collection box 6 is fixedly installed in water storage tank 1. Collection box 6 is located below installation pipe 4. Collection box 6 is connected to the end of installation pipe 4 away from water inlet pipe 2 through connecting pipe. Collection box 6 is provided with collection dish 7. The inner wall of collection dish 7 is lined with cushioning cotton.
[0033] The water treatment component is fixedly installed at the bottom of the water storage tank 1. One end of the water treatment component is connected to the bottom of the collection tank 6, and the other end of the water treatment component is connected to the water pump 3.
[0034] An internal circulation system, consisting of a water pump 3, water treatment components, installation pipes 4, and connecting pipes, enables water circulation and purification, continuously removing impurities, harmful microorganisms, and organic matter, ensuring a stable incubation water environment. An inverted cone-shaped egg-bearing incubation container 5 serves as a habitat for the egg-bearing shrimp; stacking or arranging multiple containers in an array improves space utilization. A collection dish 7 with cushioning cotton collects the hatched shrimp eggs that flow down the pipes.
[0035] The design was further optimized by arborescent container 5 being an inverted cone shape with an opening 8 at the bottom. The bottom of arborescent container 5 is inserted into and connected to installation pipe 4. Arborescent shrimp are cultured using the inverted cone-shaped arborescent container 5. Water flows through the installation pipe 4 and then through the opening 8 at the bottom of the arborescent container 5, increasing water flow and ensuring sufficient oxygen. When the shrimp eggs hatch and separate from the arborescent shrimp, they will move with the water flow to the collection box 6 for collection.
[0036] The design was further optimized by adding several water-permeable holes to the side walls of the brooding incubation container 5.
[0037] Further optimization of the scheme involves a water treatment component comprising an ozone sterilizer 9, a biological filter 10, a protein skimmer 11, and a microfilter 12, all located sequentially and connected to the bottom wall of the reservoir 1. The ozone sterilizer 9 is connected to the water pump 3, and the microfilter 12 is connected to the bottom of the collection tank 6. After starting the water pump 3, water is sequentially passed through each part of the water treatment component, ensuring that the water entering the egg-bearing incubation container 5 meets the water quality requirements for the egg-bearing incubation of *Procambarus clarkii*, removing harmful substances and ensuring suitable dissolved oxygen and other indicators.
[0038] The design was further optimized, with the taper of the egg-bearing incubation container 5 set at 1:2-1:4; the inner wall of the egg-bearing incubation container 5 is smooth. The smooth, edgeless inner wall prevents damage to the red swamp crayfish and its eggs.
[0039] The design has been further optimized. The buffer cotton is made of an elastic, porous material with a thickness of 3cm-8cm and a pore size of 0.8mm-0.2mm. This design effectively buffers the water while ensuring smooth water flow, providing ample oxygen for the eggs.
[0040] The design was further optimized by filling the biological filter 10 with biological filter media, which is a mixture of activated carbon and quartz sand, with a volume ratio of activated carbon to quartz sand of 1:3 to 1:5. The particle size of the biological filter media is 5mm-12mm. This design improves the filtration effect of water, adsorbs impurities in the water, and cultivates beneficial microorganisms to improve water quality.
[0041] The design has been further optimized by adding a flow guide hole at the bottom of the collection dish 7. A filter screen with a detachable aperture of 0.3-0.8mm is attached to the flow guide hole to facilitate water flow and collection of larvae.
[0042] To further optimize the design, flow control valves are installed in the connecting pipes at both ends of pipe 4. These valves are used to regulate the water flow velocity in each section of the pipe, ensuring that the water flow velocity within the inverted conical egg-bearing incubation container is suitable for the egg-bearing incubation needs of the red prawn.
[0043] The process of using this invention is as follows: Berried shrimp are placed in the berried incubation container 5 for rearing. A water pump 3 and a water treatment component circulate and treat the water flow, ensuring that the water flows through the installation pipe 4. During this flow, the water passes through the opening 8 at the bottom of the berried incubation container 5, facilitating water exchange within the container and maintaining both water flow and oxygen levels to create an environment suitable for incubation. When the shrimp eggs hatch and separate from the berried shrimp, the hatched eggs are carried by the water flow to the collection dish 7 for collection.
[0044] Example 2:
[0045] Reference Figure 2-3This embodiment provides a device for hatching eggs of *Procambarus clarkii*. The difference between this embodiment and Embodiment 1 is that the collecting dish 7 is located inside the collecting tank 6. The side walls of the collecting tank 6 and the water storage tank 1 are respectively provided with through grooves corresponding to the collecting dish 7. A connecting block 13 is fixedly connected to one end of the collecting dish 7, and the connecting block 13 slides within the through groove. A groove 14 is provided on the inner wall of the collecting tank 6, leaving a gap between the inner wall of the collecting tank 6 with the groove 14 and the side wall of the collecting dish 7. A guide hole is provided on the side wall of the collecting dish 7, and the guide hole is set higher than the bottom surface of the collecting dish 7. When collecting shrimp eggs using this collecting dish 7, some water will remain in the collecting dish 7, providing a basis for the survival of the shrimp eggs. When the water level moves to the guide hole, the water exceeding the guide hole will flow out through the buffer cotton and the guide hole into the water treatment component. Maintaining a certain liquid level in the collecting dish 7 also improves the buffering effect against shrimp eggs falling. A handle 15 is fixedly connected to the connecting block 13. When it is necessary to remove the collection dish 7, simply pull the handle 15, and the collection dish 7 will move to the outside of the water storage tank 1 through the connecting block 13, so as to facilitate the collection and processing of shrimp eggs in the collection dish 7.
[0046] Furthermore, several support rods are fixedly connected inside the collection box 6, and these support rods are arranged in contact with the bottom surface of the collection dish.
