Description

Technical Field

[0001] The present application relates to the technical field of sexual reproduction of corals, and in particular to a sperm and egg collection device based on a coral mosaic. Background Art

[0002] Coral reefs are among the most biodiverse ecosystems on Earth, often called "tropical rainforests of the ocean." Reef-building corals, the primary framework organisms of coral reef ecosystems, form complex habitats. However, due to environmental degradation and the impact of human activities, coral reefs are facing severe ecological pressures and are in urgent need of restoration efforts.

[0003] Currently, the main restoration method relies on asexual reproduction of corals. Although this method can lead to rapid population expansion, it cannot increase the genetic diversity of the population, nor can it alleviate the potential lack of adaptability of coral populations to future environmental changes. Therefore, new coral reef ecological restoration work should be carried out based on consideration of genetic diversity. Sexual reproduction of corals can achieve genetic recombination through gamete hybridization, thereby increasing the genetic diversity of the population. However, due to the complex and changing environment of natural sea areas, the survival rate of coral gametes is generally low, which limits the success rate of fertilization and the recruitment rate of juveniles. The use of relevant devices to collect coral sperm and eggs in situ and conduct subsequent artificial breeding can significantly improve the fertilization rate, but the current collection equipment is inefficient in collecting sperm and eggs and has poor resistance to wind and waves.

[0004] Therefore, how to achieve the wind and wave resistance of the lifting device and the collection efficiency of coral sperm and eggs is a problem that needs to be solved by those skilled in the art. Utility Model Content

The cover plate 104 is provided with two through holes. The second end of the second U-shaped tube 102 and the second end of the third U-shaped tube 103 respectively pass through the two through holes and are threadedly connected to the fastening nut 105.

[0037] The first U-shaped tube 101 in the embodiment of the present application can be integrally connected to the first end of the second U-shaped tube 102 and the first end of the third U-shaped tube 103, thereby improving the strength of the connecting device 1. The second U-shaped tube 102 and the third U-shaped tube 103 are arranged in parallel, and the distance between the second U-shaped tube 102 and the third U-shaped tube 103 is used to allow the connecting rod 5 in the coral puzzle to pass through. The second ends of the second U-shaped tube 102 and the third U-shaped tube 103 are both provided with threads for threaded connection with the fastening nut 105. Figure 5 The connecting tube 203 passes through the second U-shaped tube 102 and the third U-shaped tube 103 in sequence. The connecting rod 5 in the coral puzzle is located above the connecting tube 203, passing through the gap between the second U-shaped tube 102 and the third U-shaped tube 103, and the connecting rod 5 is located below the first U-shaped tube 101 and the cover 104. The fastening nut 105 can be tightened to firmly connect the connecting tube 203 and the connecting rod 5, and the connecting tube 203 and the connecting rod 5 in the coral puzzle are cross-shaped and interlaced.

[0038] Furthermore, the cover 104 is provided with an arc-shaped protrusion 1401, which is adapted to the circumference of the connecting rod 5 in the coral mosaic. The arc-shaped protrusion 1401 is located between the two through holes, and the arc opening of the arc-shaped protrusion 1401 is oriented in the same direction as the arc opening of the first U-shaped tube 101. By providing the arc-shaped protrusion 1401 on the cover 104 to adapt to the circumference of the connecting rod 5, the contact area between the cover 104 and the connecting rod 5 in the coral mosaic can be increased, thereby improving the firmness of the connection between the connecting device 1 and the coral mosaic.

[0039] Based on the above embodiment, the embodiment of the present application further includes a camera and a wireless communication module connected to the camera. The camera is located on the top of the collection skeleton 2 and is used to detect the discharge of coral sperm and eggs on the coral platform in real time. The captured coral sperm and egg discharge situation is fed back to the terminal through the wireless communication module. The staff can use the terminal to determine the amount of coral sperm and eggs collected by the enrichment device 4 based on the coral sperm and egg discharge situation, thereby timely collecting the coral sperm and eggs in the enrichment device 4. The embodiment of the present application does not limit the type of wireless communication module, which can be a WIFI module or a 5G module, etc.; the present application also does not limit the type, quantity, and installation method of the camera.
