Description

Technical Field

[0001] The utility model relates to the technical field of aquaculture, and in particular to a soft coral intensive asexual reproduction device and system. Background Art

[0002] Soft corals are of various types and have soft and beautiful shapes. They are an important part of the coral reef ecosystem and have strong medicinal value. In recent years, the ecosystem of coral reef areas has been continuously destroyed, and the number of corals in the wild has continued to decrease. At the same time, with the gradual expansion of the domestic and foreign ornamental aquarium market, the demand for soft corals in the coral trade has gradually increased, thus posing a severe challenge to the wild population of soft corals.

[0003] Protecting natural coral reef resources and conducting research on artificial coral propagation are two effective ways to protect coral resources. By utilizing the asexual reproduction characteristics of soft corals and breeding a large number of offspring corals through appropriate artificial techniques, we can not only meet the growing demand for corals in the ornamental aquarium market and reduce dependence on wild corals, but also return them to the sea to expand the number of wild coral colonies and restore the ecological environment of coral reef areas. Therefore, the research and development of intensive and rapid asexual propagation devices for soft corals reflects a strong necessity and positive practical significance.

[0032] First embodiment

[0033] Please refer to Figure 1 The present embodiment provides an intensive asexual propagation device 10 for soft corals, which includes a propagation mechanism 40, a propagation base 30 and a net cover mechanism 20; the propagation mechanism 40 includes a bottom plate 405 and a surrounding plate 401, the surrounding plate 401 is installed at the edge of the bottom plate 405, and forms a propagation area 400 for soft corals with the bottom plate 405; the bottom plate 405 and the surrounding plate 401 are both provided with a hollow structure; the hollow structure is composed of a plurality of hollow holes; the propagation base 30 is used for propagating soft corals, and a plurality of propagation bases 30 can be detachably placed in the propagation area 400; the net cover mechanism 20 can be detachably embedded in the interior of the surrounding plate 401.

[0034] It should be noted that, in this embodiment, the enclosure 401 is vertically installed just above the edge of the bottom plate 405. In other embodiments of the utility model, the enclosure 401 can be installed according to actual needs, for example, the top of the enclosure 401 can be biased toward the inside of the breeding area 400, or it can be biased toward the outside of the breeding area 400.

[0035] Please refer to Figure 2 In the present embodiment, the breeding mechanism 40 further includes a plurality of supporting fixing members 410 arranged at the bottom of the base plate 405 and a plurality of top clamps 411 arranged at the top of the enclosure 401; each top clamp 411 is also provided with a card slot 413, and the card slot 413 matches the position and size of the supporting fixing member 410; when a plurality of breeding mechanisms 40 are stacked, the plurality of supporting fixing members 410 of the upper breeding mechanism 40 of two adjacent breeding mechanisms 40 are respectively inserted into the plurality of card slots 413 of the plurality of top clamps 411 of the lower breeding mechanism 40.

[0036] It should be noted that a plurality of support fixings 410 are vertically arranged at the bottom edge of the bottom plate 405, specifically arranged below the intersection of each two sides of the bottom; the top clamp 411 is arranged at the top of the intersection of the enclosure 401, and is arranged corresponding to the plurality of support fixings 410. In other embodiments of the utility model, the number of support fixings 410 and top clamps 411 can be reasonably arranged according to the shape of the bottom plate 405, and their installation positions can be reasonably added to each side of the bottom plate 405 according to the size of the bottom plate 405 and the enclosure 401. The utility model does not specifically limit the fixing method of the support fixing 410 and the card slot 413, and appropriate buckle fixing, screw fixing, etc. can be selected according to actual needs.

[0037] It should be noted that the outer periphery of the slot 413 of the top clamp 411 can be detachably mounted on the edge of the slot 413, which is convenient for repairing and replacing the outer periphery of the slot 413 when it is damaged, and is convenient for installing and removing the net cover mechanism 20. When the breeding mechanisms 40 are stacked, the outer periphery of the slot 413 can increase the stability of the upper breeding mechanism 40; secondly, the existence of the outer periphery of the slot 413 can prevent the net cover mechanism 20 from being moved out of the breeding mechanism 40 due to the impact of the water flow in the breeding water body.

[0038] In other embodiments of the utility model, a detachable protrusion (not shown in the figure) is provided on the inner side of the top of the enclosure 401, and the protrusion is evenly arranged above the hollow hole 403 of the enclosure, and its vertical height is lower than the height of the periphery of the slot 413, and is used to support the outer frame body 209 of the net cover mechanism 20. The combined use of the protrusion and the periphery of the slot 413 can ensure that the net cover mechanism 20 is inside the breeding mechanism 40 during the breeding period of the soft coral, and avoid the displacement of the net cover mechanism 20 due to excessive water flow during operations such as changing water, thereby causing damage to the cultured tissue inside the breeding area 400. In addition, the provision of the protrusion does not affect the vertical force of the net cover mechanism 20 on the cultured coral tissue.

[0039] It should be noted that the distance between the protrusion and the periphery of the slot 413 is greater than the height of the net cover mechanism 20, and the net cover mechanism 20 can move up and down in real time between the two as the breeding water flows.

[0040] In this embodiment, the bottom plate 405 of the breeding mechanism 40 is a rectangular structure, and the enclosure 401 is installed at the edge of the bottom plate 405. Therefore, the enclosure 401 is also a rectangular structure, and the shape of the bottom plate 405 of the breeding mechanism 40 determines the shape of the entire breeding device 10. In other embodiments of the utility model, the shape of the bottom plate 405 can be reasonably adjusted according to actual needs, for example, the shape of the bottom plate 405 can be circular, trapezoidal or parallelogram, etc.; the bottom of the enclosure 401 can be selectively installed on the plate surface of the bottom plate 405 or connected to the edge of the bottom plate 405.

[0041] The bottom plate 405 and the enclosure 401 of the breeding mechanism 40 are both made of acrylic material, which is a high-strength, high-transparency plastic sheet, also known as organic glass. Its high transparency can ensure that sufficient light can be irradiated to the soft coral tissue cultured inside the breeding mechanism 40 in the breeding water. The acrylic material has excellent resistance strength and is safer to use. Even if it is subjected to strong impact and vibration, it will not break, which can effectively extend the service life of the breeding mechanism 40.

[0042] In addition, the light transmittance of acrylic material is over 90%, which is conducive to retaining the light needed for coral growth to the maximum extent. At the same time, the material used has good chemical stability, avoiding the production of harmful substances in the water.

[0043] The hollow structure provided on the bottom plate 405 and the enclosure 401 can make the water flow inside and outside the breeding mechanism 40 smooth, which is convenient for the exchange of water nutrients and the discharge of metabolic waste of soft corals, and at the same time makes it difficult for harmful substances to be deposited on the surface of the bottom plate 405 and the breeding base 30.

[0044] Furthermore, the breeding mechanism 40 has a length ≥20 cm, a width ≥15 cm, a thickness ≥0.2 cm, and a height ≥3.5 cm.

[0045] Furthermore, the breeding mechanism 40 has a length of 20 cm, a width of 15 cm, a thickness of 0.2 cm, and a height of 3.5 cm. In other embodiments of the utility model, the size setting of the breeding mechanism 40 can be reasonably adjusted according to actual needs.

[0046] It should be noted that, in this embodiment, the length and width of the breeding mechanism 40 are determined by the size of the bottom plate 405, and the thickness of the breeding mechanism 40 is directly related to the number of cultured soft corals and the number and size of the breeding bases 30 placed on the bottom plate 405, which can be reasonably adjusted and prepared according to actual needs; the height of the breeding mechanism 40 is determined by the height of the enclosure 401. The setting of the height, on the one hand, needs to adapt to the size of the target coral breeding individuals, and on the other hand, needs to meet the opening of the hollow structure size on the enclosure 401 and meet the soft coral tissue in the breeding area 400 can get sufficient light.

[0047] The hollow structure is composed of a plurality of hollow holes. The utility model does not specifically limit the shape of the hollow holes, and any one or more of square, rectangular, circular and triangular can be selected according to actual needs. In this embodiment, the hollow holes are designed to be rectangular, and are evenly distributed on the bottom plate 405 and the enclosure 401 in the form of a matrix.

[0048] Specifically, the hollow holes 407 of the bottom plate are designed in two rows along the length direction of the breeding mechanism 40, and each row is designed with 6 hollow holes of uniform size; the hollow holes 403 of the enclosure are designed along the placement direction of the enclosure 401, wherein the enclosure 401 in the same direction as the length direction of the breeding mechanism 40 is uniformly designed with a row of 12 hollow holes of uniform size, and the enclosure 401 in the same direction as the width direction of the breeding mechanism 40 is uniformly designed with a row of 6 hollow holes of uniform size. In other embodiments of the utility model, the arrangement of the hollow holes and the design quantity can be reasonably adjusted according to actual needs; hollow holes of different shapes can also be selected to design them into required shapes to enhance aesthetics and applicability.

[0049] It should be noted that the size of the hollow hole cannot be set too large to prevent other organisms outside the breeding device 10 from entering the breeding area 400 and causing damage to the cultivated soft coral tissue.

[0050] Specifically, the size of the hollow hole is designed according to the size of the bottom plate 405 and the enclosure 401, and can be reasonably adjusted according to actual needs. In this embodiment, the size of the hollow hole 407 of the bottom plate is 0.5 cm × 5 cm, and the size of the hollow hole 403 of the enclosure is 0.5 cm × 2 cm. In other embodiments of the utility model, the size of the hollow hole can be reasonably set and adjusted according to the shape of the hollow hole actually designed.

[0051] Please refer to Figure 2 In this embodiment, the breeding mechanism 40 also includes a suction cup 420 arranged on the side of the enclosure 401 for hanging the breeding mechanism 40.

[0052] Furthermore, the suction cup 420 is made of silicone and is equipped with a fixed spiral buckle, so that the breeding mechanism 40 can be adsorbed and suspended according to actual needs, thereby maximizing the use of the breeding water space and realizing intensive breeding of soft corals.

[0053] It should be noted that, considering the existence environment of the breeding water body, the wall of the cylinder will be relatively smooth due to the growth of algae, and to ensure the stability of the breeding mechanism 40, the suction cup 420 is a conventional knob-type suction cup 420 on the market, which is easy to use, has strong adsorption force, is applicable to a wide range of scenarios, and does not require additional power supply.

[0054] In other embodiments of the utility model, the suction cup 420 can be selectively installed and disassembled according to actual needs. When the breeding mechanism 40 is stacked and laid flat, the suction cup 420 can be disassembled; when the breeding mechanism 40 is hung, the suction cup 420 can be installed on the side of the enclosure 401.

[0055] Please refer to Figure 3 In this embodiment, the breeding base 30 is used to breed and cultivate the soft corals to be bred, and a plurality of breeding bases 30 can be detachably placed in the breeding area 400 .

[0056] Furthermore, the length of the breeding base 30 is ≥4.0cm, the width is ≥3.0cm, and the thickness is 0.3-0.5cm. The specifications of the breeding base 30 can be reasonably adjusted according to the size of the bottom plate 405 of the breeding mechanism 40, as well as the number and size of the tissues that need to be propagated. Specifically in this embodiment, the number of breeding bases 30 is set to 16 pieces, which can be reasonably adjusted according to the actual size of the base used. The design of a batch of breeding bases 30 in a single breeding mechanism 40 can quickly increase the number of corals that are propagated, greatly alleviate the shortage of corals in the ornamental aquarium market, and help the release and restoration of corals and the batch supply of scientific research experimental samples.

[0057] Furthermore, the breeding base 30 has a length of 4.0 cm and a width of 3.0 cm.

[0058] It should be noted that the material of the breeding base 30 is selected from any one of ceramics and stone materials. Specifically in the present embodiment, the material of the breeding base 30 is ceramics, because the ceramic material is safe and non-toxic, does not pollute the water quality, has low cost, is relatively large in quality, and has good submergence and fixity. In addition, since the ceramic sheet is brittle, its thickness and size need to be reasonably adjusted according to actual conditions. When the thickness of the ceramic sheet is thin and the size is large, it is easy to cause damage in the process of using the ceramic sheet.

[0059] In this embodiment, the side of the bottom plate 405 of the breeding base 30 away from the breeding mechanism 40 is a rough surface. The rough surface can make the coral individuals attach and grow quickly and naturally without falling off, shortening the coral attachment time, improving the convenience of subsequent overall transplantation, protecting the bottom tissue of the coral to the maximum extent during the transplantation process, and helping the subsequently transplanted corals to adapt to the new environment in a short time, thereby improving the transplantation survival rate. After the coral individuals and the ceramic sheet are completely attached and fixed, the corals and the fixed ceramic sheet can be regarded as a new whole and continue to be transferred to the desired area, which is flexible and convenient.

[0060] Please refer to Figure 4 In the present embodiment, the mesh cover mechanism 20 is provided with a double layer; the length of the mesh cover mechanism 20 is ≥19cm, the width is ≥14cm, and the height is 0.5-1.0cm; each layer of the mesh cover mechanism 20 includes a grid 203 and a gauze 205, and the grid 203 includes an outer frame body 209 and an internal support frame 207; the outer frame body 209 is matched with the size of the enclosure 401, and the outer frame body 209 is detachably embedded in the top inner side of the enclosure 401; the internal support frame is arranged inside the outer frame body 209, for fixing the outer frame and supporting the gauze 205; the material of the gauze 205 is white nano PP, and the aperture of the gauze 205 is ≥10 meshes.

[0061] Furthermore, the net cover mechanism 20 has a length of 19 cm, a width of 14 cm, and a height of 0.5 cm.

[0062] It should be noted that the double-layer mesh cover mechanism 20 is of moderate weight and is naturally pressed on the surface of the coral tissue of the breeding base 30. The mesh cover design of the breeding mechanism 40 avoids the damage to the coral tissue caused by traditional glue bonding, so that the coral individuals are naturally pressed and adhered to grow on the base; the gauze 205 is made of white nano PP material, which has good chemical stability, acid and alkali resistance, corrosion resistance, and oil resistance. It is not easy to adhere to the coral individuals during use, and the appropriate elasticity avoids leaving indentations on the coral surface; the specifications of the aperture of the gauze 205 can be reasonably adjusted according to the size of the cultivated corals. The setting of the gauze 205 is conducive to the exchange of nutrients in the water, daily nutrient feeding, the discharge of coral metabolic waste, and the effective isolation of interference from other organisms in the water.

[0063] In this embodiment, the net cover mechanism 20 further includes a hand piece 201 ; the hand piece 201 is disposed at one end of the net cover mechanism 20 away from the bottom plate 405 of the breeding mechanism 40 , so as to facilitate installation and removal of the net cover mechanism 20 .

[0064] It should be noted that the material of the handpiece 201 is not particularly limited in the present invention, and the material has the characteristics of good chemical stability, acid and alkali resistance, corrosion resistance and strong light transmittance. In other embodiments of the present invention, the number of handpieces 201 can be reasonably set according to the size of the net cover mechanism 20. Specifically in this embodiment, the number of handpieces 201 is 1, and the material of the handpiece 201 is acrylic.

[0065] Please refer to Figure 1-Figure 4 The specific operation of the soft coral intensive asexual reproduction device 10 provided by the utility model for soft coral reproduction is as follows: put the reproduction mechanism 40 into the water body, lay the required number of reproduction bases 30 (i.e., ceramic sheets) on the bottom plate 405 of the reproduction mechanism 40, and ensure that there is a gap between adjacent reproduction bases 30 to facilitate the flow and exchange of seawater. The prepared soft coral fragments to be asexually reproduced (similar in size) are placed in the center of the reproduction base 30 in sequence. After placement, the net cover mechanism 20 is slowly placed into the reproduction mechanism 40 and carefully placed on the surface of the coral tissue to ensure that each coral tissue is under pressure. At this time, the preparation of the single reproduction device 10 is completed. Ensure that the placement position is adequately illuminated by light (the light illumination can be selected in a direct or oblique manner according to actual needs); repeat the above steps, and after all the reproduction devices 10 are prepared, lay and stack the reproduction devices 10 on the bottom of the reproduction water body, and maximize the use of light and space in the water body while high-density reproduction of corals. After one week of breeding and cultivation, the soft coral breeding limbs can be attached and fixed to the breeding base 30, and grow well, and the tentacles have been normally extended. At this time, the limbs can be taken out together with the breeding base 30 for subsequent cultivation or conventional breeding.

[0066] This embodiment also provides an intensive asexual propagation system for soft corals, which is composed of one or more propagation devices 10 that are laid flat, stacked, or hung, and which maximizes the use of light and space in the water body while propagating corals at a high density.

[0067] First Experimental Example

[0068] Select a healthy and stretched Sarcophyton soft coral as the mother body, use a sterile scalpel to cut out the tissue to be propagated from the mother body, and then cut it into asexual propagation limbs of 1.5cm×1.5cm. Place the propagation mechanism 40 in the water body, and lay the required number of propagation bases 30 (i.e., ceramic sheets) on the bottom plate 405 of the propagation mechanism 40, ensuring that there is a gap between adjacent propagation bases 30 to facilitate the flow and exchange of seawater. Place the asexual propagation limbs in the center of the propagation base 30 in turn. After placement, slowly place the net cover mechanism 20 into the propagation mechanism 40 and press it on the surface of each coral tissue. At this time, the preparation of a single propagation device 10 is completed, and ensure that the placement position is adequately illuminated by light. Repeat the above steps. After all the propagation devices 10 are prepared, lay and stack the propagation devices 10 at the bottom of the propagation water body. After about 1 week, the reproduction limbs of the fleshy soft coral can be attached and fixed to the reproduction base 30. It can be clearly seen that the fleshy soft coral tissue has been completely and naturally attached to the base and has grown well, and the tentacles have been normally extended. At this time, the limbs can be taken out together with the reproduction base 30 for subsequent placement and conventional breeding.

[0069] Second Experimental Example

[0070] Select several healthy and stretched mushroom corals, and use a sterile scalpel to cut each coral into two equal halves along the middle of its mouthparts. Place the breeding mechanism 40 in the water body, and lay the required number of breeding bases 30 on the bottom plate 405 of the breeding mechanism 40, ensuring that there is a gap between adjacent breeding bases 30 to facilitate the flow and exchange of seawater. Place the mushroom coral breeding individuals in the center of the breeding base 30 in turn, ensuring that the bottom of the coral is placed on the upper surface of the breeding base 30. After the placement is completed, slowly put the net cover mechanism 20 into the breeding mechanism 40 and press it on the surface of each coral tissue. At this time, the preparation of a single breeding device 10 is completed, and ensure that the placement position is illuminated by sufficient light. Repeat the above steps. After all the breeding devices 10 are prepared, the breeding device 10 is adsorbed on the inner wall of the breeding tank through the knob-type suction cup 420. After about 1 week, the mushroom coral breeding individuals are attached and fixed to the breeding base 30. It can be clearly seen that the mushroom coral tissue is naturally fixed to the base and begins to self-repair and grow towards a complete round shape. Subsequently, large-scale breeding of mushroom corals can be achieved.

[0071] In summary, the soft coral intensive asexual reproduction device 10 provided by the utility model has a simple structure and is easy to install. The hollow structure design of the bottom plate 405 of the reproduction mechanism 40 and the enclosure 401 allows the substances and water flow inside and outside the reproduction mechanism 40 to be fully exchanged, and harmful substances are not easily deposited; during the soft coral reproduction process, the natural pressure of the net cover mechanism 20 on the soft coral individuals allows them to naturally attach and grow on the reproduction base 30, avoiding the damage to the soft coral tissue caused by the traditional glue bonding method, or the inability to fix the coral tissue due to the secretion of more mucus; the double-layer setting of the net cover mechanism 20 can effectively isolate the external interference of other organisms; the relatively independent placement of multiple reproduction bases 30 on the bottom plate 405 is conducive to the intensive asexual reproduction of soft corals.

[0072] The soft coral intensive asexual reproduction system provided by the utility model is placed in the breeding water body in a manner selected from at least one of flat laying, stacking and side wall adsorption suspension, which can efficiently breed corals in batches, save space to the maximum extent, and realize intensive management. In addition, the breeding system can also alleviate the shortage of corals in the ornamental aquarium market, reduce the demand for wild collection of corals, and help coral release and restoration and batch supply of scientific research experimental samples.

[0073] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
