Description

Technical Field

[0001] The invention relates to the technical field of seawater aquaculture, to a sea cucumber multiplication catching technology for artificial fish reefs, and in particular to a sea cucumber catching device and method for artificial fish reef areas. Background Art

[0002] Marine aquaculture is an important part of my country's aquatic product supply, accounting for 1 / 3 of the total output of aquatic products. In recent years, with the rigid increase in demand for marine products, the saturation of offshore aquaculture capacity, and the contradiction between industrial development and the ecological environment, the marine ranch ecological aquaculture model with artificial reefs as the main means has become the main development trend of marine aquaculture. The construction of artificial reefs has great strategic significance and far-reaching historical significance for the construction of marine ranches, the restoration and improvement of the marine ecological environment, the proliferation and optimization of fishery resources, the rescue of rare and endangered species and the protection of biodiversity, and the promotion of the sustainable and healthy development of the marine economy.

[0003] Artificial reefs generally have a significant fish gathering effect, which can prolong the time that fish stay in the reef area, expand the fishing ground, and increase the number of fish. It has been found that the fish that have good fish gathering and increase the number of fish are flounder, flatfish, sea bream, and sedentary reef fish such as grouper, black carp, and six-line fish. The utilization rate and catch of fishing operations in artificial reef areas are generally higher than those in the surrounding sea areas, and some catches can be doubled. The effect of shallow sea proliferation reefs is also obvious and stable. Artificial reef areas in the Yellow Sea and Bohai Sea mostly carry out bottom seeding and increase of sea cucumbers with higher economic value, and take into account the natural gathering of crabs, snails, fish and other organisms. The traditional method of catching sea cucumbers in artificial reef areas is mainly underwater catching by divers. This method of catching is dangerous for operators and has high labor costs. It is difficult to catch in some sea areas with turbid water or strong wind and wave effects. In recent years, many scientific research institutes and enterprises have focused on the research and development of underwater robots for catching sea cucumbers in artificial reef areas, but there is still a long way to go before practical application. Summary of the invention

[0004] The sea cucumber trapping device used in artificial reef areas adopts a cage structure. The cage frame is made of corrosion-resistant metal profiles or PE profiles. A soft nylon net is fixed on the cage frame to form the bottom of the cage and the surrounding of the cage body; The cage body is provided with movable doors which are movably connected and can be opened and closed around it, so that the sea cucumbers in the artificial fish reef area can enter the cage body.

[0005] Furthermore, the movable door is a hinge mesh, the upper end of the hinge mesh is movably connected to the hinge fixed shaft through a hinge sleeve, the hinge sleeve ring is connected to the hinge fixed shaft and can rotate around the hinge fixed shaft, and the hinge fixed shaft is fixedly installed on the cage frame; the lower end of the hinge mesh is connected to the float to ensure that the lower end of the hinge mesh is opened upward under the action of the float when used underwater, so that the sea cucumbers in the artificial fish reef area can enter the cage.

[0006] Further preferably, the hinge mesh is made of a hard mesh, or is made of a rigid frame and a soft nylon mesh.

[0007] Further preferably, the hinge mesh is installed on the outside of the box body, and the lower end of the hinge mesh extends out of the box body and opens upward.

[0008] Furthermore, the top of the cage frame is connected to a retractable cable, and a positioning buckle is provided on the retractable cable. The positioning buckle is movably sleeved on the fixed-point cable, and the fixed-point cable is connected to the fixed-point anchoring device on the seabed, that is, the positioning buckle is sleeved outside the fixed-point cable and can slide along the fixed-point cable, and is used for the fixed-point delivery of the sea cucumber trapping device and the fixation when it is in use on the seabed.

[0009] Further preferably, the position of the positioning buckle on the retractable cable is equal to the side length or radius of the sea cucumber trapping device box at a distance from the connection between the retractable cable and the sea cucumber trapping device.

[0010] Furthermore, the positioning buckle is a shackle or a ring.

[0011] Furthermore, the top of the cage frame is covered with a soft nylon mesh to prevent the trapped organisms in the cage from escaping.

[0012] The method for trapping sea cucumbers in artificial reef areas using the above-mentioned sea cucumber trapping device for artificial reef areas is specifically implemented in the following steps: (1) Selection of placement location for sea cucumber trapping devices Select the interval area of ​​the reef in the artificial reef area as the fixed placement position of the sea cucumber trapping device, drive the fixed anchoring device into the seabed for positioning, connect the fixed anchoring device with a fixed cable, tie a fixed buoy to the top of the fixed cable, and float on the sea surface for positioning and marking; (2) Fixed-point placement and trapping of sea cucumber trapping devices When the sea cucumbers are in hibernation or hibernation, the sea cucumber trapping device is released; bait is placed in the sea cucumber trapping device, the positioning buckle on the retracting cable is movably connected to the fixed-point cable, the sea cucumber trapping device is weighted and released into the sea along the fixed-point cable to achieve fixed-point release, and then the end of the retracting cable of the sea cucumber trapping device on the sea surface is tied to the fixed-point buoy; After the sea cucumber trapping device is put into the sea, the lower ends of the hinged mesh sheets of the movable door around it are opened upwards under the action of the floating ball, so that the sea cucumbers in the artificial reef area enter the sea cucumber trapping device under the action of the trapping bait; (3) Harvesting of sea cucumbers using trapping devices When harvesting, the retracting and releasing cable connected to the sea cucumber trapping device is untied at the fixed floating ball, and the retracting and releasing cable is lifted. At this time, the buoyancy of the floating ball connected to the lower end of the hinged mesh is less than the impact of the water flow, and the hinged mesh is closed, so that the sea cucumber in the sea cucumber trapping device is harvested; (4) Repeat steps (1) to (3).

[0013] Furthermore, the selection of the placement position and the fixed-point placement of the sea cucumber trapping device, for the sea area of ​​artificial fish reefs with regular strip-shaped or fixed reef spacing, the strip-shaped interval area between two artificial fish reef groups, or the strip-shaped interval area that can be demarcated, is selected as the placement position of the sea cucumber trapping device, and two fixed-point anchoring devices are driven into the seabed along the length direction of the strip-shaped interval area for fixing, the fixed-point anchoring devices are connected to the fixed-point cables, the top of the fixed-point cables are connected to the fixed-point buoys, the fixed-point buoys float on the sea surface, the fixed cables are connected between the tops, the fixed cables are spaced to tie multiple sea cucumber trapping devices by retracting and releasing the cables, and multiple fixed-point buoys are arranged on the fixed cables, and the fixed-point buoys float on the sea surface.

[0014] Furthermore, the length of the fixed cable does not exceed 120 meters.

[0015] Furthermore, the trapping bait is a solid granular material with a slow-release capability and does not disperse when released. After the sea cucumber trapping device is stabilized on the seabed, it gradually disperses.

[0016] The beneficial effects of the present invention compared with the prior art are: After the sea cucumbers in the artificial reef area finish their summer and winter hibernation, they will gradually come out from the gaps in the artificial reef to forage for food. As the density of sea cucumbers around the artificial reef increases, the amount of natural bait will gradually decrease and thus fail to meet the feeding needs of the sea cucumbers, and the sea cucumber activity range will gradually expand. The present invention utilizes the biological habits of sea cucumbers and innovatively proposes a trapping device and method design, which has the following advantages over existing capture methods: 1. The sea cucumber harvesting device of the present invention has a simple and lightweight structure. The movable door that automatically opens and closes is set by utilizing the buoyancy principle. When the sea cucumber is put into the seawater for use, the movable door automatically opens under the action of buoyancy. When the sea cucumber is lifted for harvesting, the movable door automatically closes under the action of the impact force of the water flow during the ascending process. No additional power or human operation is required, which is labor-saving, low in manufacturing cost, and easy to implement. 2. Each new sea cucumber harvesting device is equipped with a separate retractable cable, which is movably connected to the fixed-point cable through a positioning buckle, so that it can be easily placed at a fixed point and fixed when in use on the seabed. When harvesting, the retractable cable can be directly hoisted. Mechanized harvesting saves time and effort, and solves many disadvantages of traditional diving harvesting, such as high risk, high cost, and limited seawater transparency. In addition, the sea cucumber harvesting devices can be reused, reducing the cost of use; 3. The new type of sea cucumber catching device is deployed and placed at fixed points according to the layout form and scale of the artificial reef area. It can be used independently or in rows. It is easy to deploy and flexible to use, and is suitable for use in various artificial reef construction waters. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0019] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means intended to limit the present invention and its application or use.

[0020] Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. It should be noted that the embodiments of the present invention and the features in the embodiments can be combined with each other without conflict. The present invention will be described in detail below with reference to the drawings and in combination with the embodiments. Example

[0021] The sea cucumber trapping device and method for artificial fish reef areas of the present invention are used to capture sea cucumbers in the sea area where artificial fish reefs are constructed in the sea area of ​​stone reefs in Changhai County, Dalian.

[0022] like Figures 1 to 3 As shown, a sea cucumber trapping device A for artificial fish reef areas adopts a square cage structure. The cage frame 5 is made of corrosion-resistant metal profiles by welding. A soft nylon net 1 is fixed on and covered on the cage frame 5 to form a cage. A movable door that can be opened and closed up and down is arranged on the outer periphery of the cage body. The movable door is a hinge mesh 2. The hinge mesh 2 is made of a hard mesh. The upper end of the hinge mesh 2 is movably connected to a hinge fixed shaft 6 through a hinge sleeve 3. The hinge sleeve 3 is connected to the hinge fixed shaft 6 and can rotate around the hinge fixed shaft 6. The hinge fixed shaft 6 is welded to the cage frame 5; the lower end of the hinge mesh 2 is connected to a float 4 to ensure that the lower end of the hinge mesh 2 extends out of the box and opens upward when in underwater use, so that the sea cucumbers in the artificial fish reef area can enter the cage.

[0023] like Figure 4 As shown, when the sea cucumber trapping device A is in use, the top of the net cage frame 5 is connected to the retracting cable E, and the retracting cable E is provided with a positioning buckle C, which is a shackle. When being released, the positioning buckle C is movably connected to the fixed-point cable D, and the fixed-point cable D is connected to the fixed-point anchoring device B on the seabed. In this embodiment, the fixed-point anchoring device B uses a wooden stake, and the positioning buckle C is sleeved outside the fixed-point cable D and slides along the fixed-point cable D, so as to achieve the fixed-point release and fixation of the sea cucumber trapping device A when in use on the seabed. In order to make the fixed-point release of the sea cucumber trapping device A more accurate and stable in the seabed position after release, the position of the positioning buckle C on the retracting cable D is preferably such that the distance a from the positioning buckle C to the connection between the retracting cable D and the sea cucumber trapping device A is equal to the side length of the sea cucumber trapping device box. If the sea cucumber trapping device A is a circular box, then a is preferably equal to the radius of the circular box.

[0024] In order to prevent the sea cucumbers trapped in the sea cucumber trapping device A used in artificial reef areas from escaping, the top of the cage can also be covered with a soft nylon net 1.

[0025] like Figure 5 As shown, the method for trapping sea cucumbers in artificial reef areas using the above-mentioned sea cucumber trapping device for artificial reef areas is specifically implemented in the following steps: (1) Selection of placement location for sea cucumber trapping device A In this embodiment, natural stone reefs are placed in the artificial fish reef area. The natural stones are placed in piles to form unit reef bodies. The intervals between the unit reef bodies are used as fixed-point placement positions for sea cucumber trapping devices A. Fixed-point anchoring devices B are driven into the seabed for fixing. Fixed-point anchoring devices B are provided with fixed-point cables D. The top of fixed-point cables D is tied with fixed-point buoys F. Fixed-point buoys F float on the sea surface for positioning and marking.

[0026] (2) Sea cucumber trapping device A is deployed at a fixed point At the end of the sea cucumber hibernation or hibernation, the sea cucumber trapping device A is released. The trapping bait is placed in the sea cucumber trapping device A. The trapping bait is solid granular material, preferably in a spherical shape, with a diameter of 6-8 cm. The trapping bait has a slow release ability and does not disperse when released. After the sea cucumber trapping device A is stabilized on the seabed, it gradually disperses. When released, the positioning buckle C on the retracting cable E is movably sleeved on the fixed-point cable D, and then the sea cucumber trapping device A is counterweighted and released into the sea along the fixed-point cable D to achieve fixed-point release, and then the end of the retracting cable E on the sea surface is tied to the fixed-point buoy F.

[0027] After the sea cucumber trapping device A is put into the sea, the lower ends of the hinged mesh sheets 2 of the movable door around it are opened upwards under the action of the floating ball 4, so that sea cucumbers and other organisms in the artificial reef area enter the sea cucumber trapping device A under the action of the trapping bait.

[0028] (3) Harvesting of sea cucumber trapping device A According to the proliferation density of sea cucumbers in the artificial reef area, the sea cucumber trapping device A is harvested 2-3 days after it is put into use. When harvesting, the retracting and releasing cable E connected to the sea cucumber trapping device A is untied at the fixed point float F, and the retracting and releasing cable E is lifted. At this time, the buoyancy of the float 4 connected to the lower end of the hinged mesh 2 is less than the impulse of the water flow, and the hinged mesh 2 is closed outside the box of the sea cucumber trapping device A, so that the sea cucumbers, conches, fish, etc. in the box of the sea cucumber trapping device A are all harvested. Since the movable door hinge mesh 2 is closed from outside the box, the sea cucumbers at the edge of the movable door will be pushed into the box instead of being pushed out of the box.

[0029] (4) Repeat steps (1) to (3). Example

[0030] The sea cucumber catching device and method for artificial fish reef areas of the present invention are used to catch sea cucumbers in the artificial fish reef construction sea area of ​​Changhai County, Dalian City. The constructed reefs are laid out in a strip shape, that is, strip-shaped interval areas appear between unit reef bodies.

[0031] The structure of the sea cucumber trapping device A for artificial fish reef areas in this embodiment is the same as that in embodiment 1, but the cage frame 5 is made of PE profile, there is no positioning buckle C on the retractable cable E, and the hinge mesh 6 is made of PE profile frame and soft nylon mesh.

[0032] like Figure 6 As shown, the method for trapping sea cucumbers in artificial reef areas using the above-mentioned sea cucumber trapping device for artificial reef areas is specifically implemented in the following steps: (1) Selection of placement location for sea cucumber trapping device A Select the strip-shaped interval area between two artificial reefs as the placement location of the sea cucumber trap A, such as Figure 7As shown, in the strip-shaped spacer area, along the length direction of the strip-shaped spacer area, two fixed anchoring devices B with fixed cables D are driven into the seabed for fixing. The top of the fixed cable D is connected to the fixed buoy F, and the fixed buoy F floats on the sea surface. The top of the fixed cable D is connected to the fixed cable G. The length of the fixed cable G is 100 meters. In order to clearly mark the position of the fixed cable G and increase the buoyancy, a plurality of fixed buoys F are arranged on the fixed cable G at intervals.

[0033] (2) Fixed-point placement of sea cucumber trapping device A and trapping of sea cucumbers At the end of the summer or winter hibernation of sea cucumbers, the sea cucumber trapping device A is released. The trapping bait is placed in the sea cucumber trapping device A. The trapping bait is solid granular material, preferably in a spherical shape, with a diameter of 6-8 cm. The trapping bait has a slow release ability and does not disperse when released. After the sea cucumber trapping device A is stabilized on the seabed, it gradually disperses. When released, the retracting cables E of multiple sea cucumber trapping devices A are tied to the fixed cable G at intervals, and the weights of the sea cucumber trapping devices A are released into the interval area of ​​the strip-shaped artificial fish reef group.

[0034] After the sea cucumber trapping device A is put into the sea, the lower ends of the hinged mesh sheets 2 of the movable door around it are opened upwards under the action of the floating ball 4, so that sea cucumbers and other organisms in the artificial reef area enter the sea cucumber trapping device A under the action of the trapping bait.

[0035] (3) Harvesting of sea cucumber trapping device A According to the proliferation density of sea cucumbers in the artificial reef area, the sea cucumber trapping device A is put into use for 2-3 days for harvesting. When harvesting, the retractable cable E connected to the sea cucumber trapping device A is untied from the fixed cable G, and the retractable cable E is lifted. At this time, the buoyancy of the float 4 connected to the lower end of the hinged mesh 2 is less than the impact force of the water flow, the hinged mesh 2 is closed, and the sea cucumbers, conches, fish, etc. in the net box of the sea cucumber trapping device A are all harvested.

[0036] (4) Repeat steps (1) to (3) until the harvest is complete.

[0037] The invention utilizes the biological habits of sea cucumbers, combines the application of artificial reef construction, and innovatively proposes a sea cucumber trapping device and method for artificial reef areas. According to the deployment form and scale of the artificial reef area, fixed-point pile deployment and sea cucumber trapping devices are deployed, and the sea cucumber trapping devices can be used independently or deployed in rows, with convenient deployment and flexible use, and are suitable for use in various artificial reef construction sea areas. The device utilizes the buoyancy principle to set an automatic opening and closing movable door, and the movable door is automatically opened under the action of buoyancy when being deployed in seawater, and is automatically closed under the action of the impact force of the water flow during the lifting and harvesting process, without the need for additional power and human operation, labor-saving, low manufacturing cost, and easy to implement. When harvesting, the retractable cable can be directly lifted, and mechanized harvesting saves time and labor, and solves the many disadvantages of traditional diving harvesting, such as high risk, high cost, and limitation of seawater transparency; and the sea cucumber trapping devices and the like can be reused, reducing the use cost.

[0038] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in this field without departing from the purpose of the present invention.
