Description

Technical Field

[0001] This utility model relates to the field of marine conservation, and in particular to a jellyfish resource conservation facility. Background Technology

[0002] Jellyfish belong to the phylum Cnidaria, class Scyphozoa, order Rhizostomeae, family Rhizostomeidae, genus *Jellyfish*. They possess high nutritional value and a unique taste, making them an important edible jellyfish in my country. Wild jellyfish are a crucial source of broodstock for jellyfish breeding. However, with increasing near-shore fishing intensity and environmental degradation, jellyfish biodiversity in near-shore waters is declining. According to data from the 2024 China Fisheries Statistical Yearbook, the national jellyfish aquaculture production reached 80,521 tons in 2023, while the catch was 147,693 tons. Wild jellyfish resources are vital for jellyfish harvesting and artificial breeding. Ensuring a sufficient jellyfish population in the sea area can effectively expand the current broodstock population for artificial breeding, avoiding aquaculture problems such as disease and deformities caused by inbreeding depression, and directly increasing fishermen's catch profits. Currently, breeding and aquaculture facilities for the artificial breeding stage of jellyfish are relatively mature, but maintenance facilities for jellyfish marine environments are relatively lacking.

[0020] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0021] In the description of this utility model, it should be understood that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0022] Combination Figures 1 to 3 This utility model discloses a jellyfish resource conservation facility, including a base 1, a main frame 2 erected on the base 1, and multiple layers of attachment layers 3 for jellyfish growth evenly spaced on the main frame 2. Each attachment layer 3 includes a support frame 31 for mounting attachment plates 33 and a support rod 32 for stabilizing the support frame 31. The support frame 31 and the support rod 32 are welded to the main frame 2. The support rod 32 is perpendicular to the main frame 2, and the support frame 31 and the support rod 32 form an angle. The attachment plate 33 is installed on the support frame 31 on the side close to the support rod 32. A mesh 34 is also provided between two adjacent support frames 31 and inside the main frame 2.

[0023] In one embodiment, the base 1 is a polygonal body cast in cement, with a partial openwork section 12. The polygonal body can be quadrilateral, pentagonal, hexagonal, etc., for example... Figure 3 As shown, in a preferred embodiment, the base 1 is a pentagonal cube with four evenly distributed perforations 12 pre-reserved during casting. The polygonal body increases the contact area between the maintenance facility and the seabed, allowing for stable placement of the facility in seawater, reducing sinking, and improving its applicability to different seabed sediments. The perforation 12 design reduces the overall weight of the maintenance facility, making it easier to deploy and move. In another embodiment, as... Figure 1 A reinforcing rib 11 is provided between the base 1 and the main frame 2. The reinforcing rib 11 provides strong support for the main frame 2, which helps the maintenance facility maintain its shape in seawater.

[0024] In one embodiment, the main frame 2 consists of multiple parallel vertical reinforcing bars pre-embedded in the base 1 during the casting process. Preferably, as shown... Figure 3As shown, the main frame 2 is composed of four steel bars, which are equally spaced to form a cubic space. In another embodiment, multiple crisscrossing beams are welded to the top of the main frame 2, and each beam is equipped with a pull ring 21. The pull ring 21 is used for transporting and deploying maintenance devices.

[0025] In one embodiment, the included angle between the support frame 31 and the support rod 32 is 15° to 20°, preferably 15°. The attachment plate 33 is located between the support frame 31 and the support rod 32. The smaller tilt angle can provide a certain protective angle for the polyps to attach to the bottom surface of the attachment plate 33, reduce water flow impact, improve the attachment rate, and at the same time play the role of a guide plate to promote water exchange between the upper and lower water layers.

[0026] In one embodiment, the attachment plate 33 is made of polyethylene, and the mesh 34 is made of nylon. By setting different attachment materials in different areas, suitable and abundant attachment space can be provided for the polyps. The alternating attachment plates 33 and mesh 34 are equidistantly distributed on the main frame 2, and the number of layers can be adjusted according to the seawater depth of the area where the maintenance facility is located. The use of mesh material allows the ocean current to pass smoothly through the maintenance device, bringing horizontal seawater exchange to the polyps while minimizing the impact of ocean currents on the maintenance facility, thus improving the stability of the maintenance facility. In particular, the mesh 34 is set at the center of each attachment layer 3, i.e., inside the main frame 2, which allows for smoother water exchange between the upper and lower parts of the maintenance facility, providing better nutrients and oxygen for the growth and development of the polyps.

[0027] In one embodiment, the attachment plate 33 includes a raised portion and a flat portion, which are spaced apart. In a preferred embodiment, the overall surface of the attachment plate 33 is rough, and the raised portion has a plurality of holes 35. The attachment plate 33 is composed of a plurality of raised portions and flat portions. The arc-shaped protrusions can increase the surface area of ​​the attachment plate, thereby increasing the attachment area of ​​the polyps, while the holes arranged at the center of the arc-shaped protrusions can improve the exchange flow of water between different attachment plates. The rough texture of the concave bottom surface of the attachment plate can help the polyps attach better.

[0028] Jellyfish go through several stages in their life cycle, from fertilized egg, planktonic larva, polyp, transverse schizophyte, discoid form to juvenile jellyfish. During the polyp stage, they transition from a planktonic to an attached lifestyle. The conservation facility disclosed in this invention provides a suitable living environment for the attached lifestyle of jellyfish polyps by creating appropriate conservation devices.
