Description

Technical Field

[0001] The invention belongs to the technical field of sea cucumber breeding, and in particular relates to a marine ranch sea cucumber conservation and proliferation reef. Background Art

[0002] Artificial reefs are the infrastructure of marine ranches. As artificial structures placed in water bodies, they provide places for marine organisms to lay eggs, forage, raise young, and provide shelter, thereby achieving the purpose of conserving and multiplying aquatic biological resources and protecting and restoring the ecological environment of water bodies. Sea cucumbers are marine treasures among aquatic products, providing the public with abundant and high-quality animal protein. Compared with other sea cucumber farming models, the quality of bottom-seeded sea cucumbers is closer to that of wild species and has higher economic value. Therefore, in order to improve the quality of sea cucumbers, artificial reefs are placed in marine ranches to provide sea cucumbers with an attachment matrix and growth space. Bottom seeding of sea cucumbers in artificial reef areas has become an important pillar industry of marine ranches in the Yellow Sea and Bohai Sea, providing economic support for the sustainable development of marine ranches.

[0003] The size of sea cucumber seedlings is an important factor affecting the economic effect of bottom seeding of sea cucumbers. Small-sized sea cucumber seedlings have low costs and a long growth time in natural waters, and have higher product quality and economic benefits. However, small-sized sea cucumber seedlings have weaker resistance to ocean current impacts after bottom seeding. As ocean currents spread more severely, the seedling survival rate in reef areas is low. How to retain small-sized sea cucumber seedlings in reef areas during bottom seeding is a key link in improving the efficiency of sea cucumber proliferation in artificial reef areas in marine ranches.

[0004] Therefore, a marine ranch sea cucumber conservation and proliferation reef is provided to solve the above problems. Summary of the invention

[0005] In order to solve the above technical problems, the present invention proposes a marine ranch sea cucumber conservation and proliferation reef, which can arrange flow reduction units and seedling protection units on the shelter body, and utilize the flow reduction unit to achieve flow reduction and wave breakup to slow down the seawater flow rate around the shelter body, and utilize the seedling protection unit to reduce the impact of ocean currents on sea cucumbers during bottom seeding, thereby avoiding serious seedling loss during bottom seeding in the marine ranch reef area.

[0006] To achieve the above-mentioned purpose, the present invention provides a marine ranch sea cucumber conservation and proliferation reef, comprising:

[0050] Specifically, the top surface of the flow reduction slope 301 is a slope structure, that is, the end close to the shelter 1 is the high end, and the end away from the shelter 1 is the bottom end. Under this structural setting, the flow reduction slope 301 can be used to mitigate the impact of seawater.

[0051] The flow reduction slope 301 and the shelter 1 may be a separate structure or an integrated structure. When the flow reduction slope 301 and the shelter 1 are combined for use, the combined structure preferably forms a terraced structure.
