Description

{Light shading ecological culture artificial reefs for sea cucumber}

The present invention relates to a sea cucumber shade ecological aquaculture, and more particularly to a sea cucumber shading ecological aquatic plant capable of eco-friendly ecology by allowing sea cucumbers to hiding and feeding aquatic life.

As fisheries consumption surges worldwide and climatic changes and overcapacity cause fisheries production to reach its limits, there is a growing interest in the aquaculture industry as the price of seafood surges. Especially, sea cucumber is an echinophyte such as starfish, and is recognized as a well-being food by sea ginseng. Consumer interest in high quality aquatic products is increasing, and the consumption of sea cucumber is steadily increasing.

Sea cucumbers are not only the eight well-being fisheries of Korea designated by the Ministry of Maritime Affairs and Fisheries, but also very important fishery resources so that they are designated as the next 10 strategic items of the National Fisheries Research and Development Institute. The government's plan to foster 10 strategic items in the fisheries sector is expected to help Korea to secure the competitiveness of export strategies in response to the increase in demand for Korean seafood due to the tsunami in Japan and the Korea-China-Japan FTA and the mineralization of fishery products in each country. It is very appropriate as a policy to foster eco-friendly aquatic products with added value.

Mass production techniques such as festive aquaculture are essential to increase sea cucumber production. In addition, it is necessary to secure a good seedling (3-50 g) and to secure a festival-style aquaculture such as tidal flats and reclaimed land.

In China, about 75% of the sea cucumber production is harvested in the festive style, whereas the Korean sea cucumber festival style is almost nonexistent. In other words, the production of sea cucumbers in Korea depends on the extraction of natural products. As the demand for sea cucumbers increases, small-sized individuals less than 100 g are over-exploited.

On the other hand, a seeding form is being made to increase the production of sea cucumbers. However, in the case of the sperm culture, the seeds of 3 ~ 4cm in body size (0.5 ~ 1g in body weight) with low survival rate are sown, and most of the seedling sea cucumber is eaten by pirate creatures The productivity is extremely low due to death.

Therefore, it is necessary to induce mass production by increasing the survival rate of the sipping style and mandating the creation of a shelter essential for increasing the production of superior products (more than 50% of the sipping cost).

In addition, it is urgent to develop aquaculture facilities and shelter structures for festive, terrestrial, and marine cage cultures that can be mass-produced in parallel with the sipping.

The same reference numerals will be used to denote the same components in the drawings, even if they are shown in different drawings.

(First Example )

FIG. 1 is a perspective view showing an example of a sea cucumber shading ecological order according to a first embodiment of the present invention, FIG. 2 is a side view of FIG. 1, FIG. 3 is a perspective view showing a frame of the external structure shown in FIG. 4 is a perspective view showing the internal structure shown in Fig.

As shown in FIGS. 1 and 2, the sea cucumber shading ecosystem according to the first embodiment of the present invention includes an outer structure 100 having a right-left symmetrical vertical section of a letter shape, And a first internal structure 200 having a vertical cross section of "? &Quot;

The outer structure 100 includes a frame 110 forming a frame of the structure as shown in FIG. 3, a light shielding film 120 forming the left and right wall surfaces of the structure as shown in FIG. 1, And a binding strap 130 binding the periphery.

The frame 110 may be made of a metal such as a coated steel, a plastic such as PVC or a wood such as bamboo, a titanium pipe, or the like. According to this embodiment, as shown in Fig. 3, three straight steel pipe pipes 112 and three steel pipe pipes 114 bent in a "? &Quot; shape are welded to form a steel pipe having a width of 1.6 m ), A height of 0.6 m (within a range of approximately 0.3 to 3 m), and a length of 2 m (within a range of approximately 0.3 to 5 m).

At this time, the steel pipe pipes 112 and 114 are preferably coated with paint or the like so as not to be corroded by seawater. The pipes 112 and 114 may be made of stainless steel, an alloy, zinc plating, titanium, or the like.

Meanwhile, the frame 110 may be configured to be assembled in a fitting manner instead of a welding method as described above. The pipe 114 in the shape of "∧" may be configured so that the angle of the frame 110 can be adjusted by using a hinge (not shown). In this case, there is an advantage that the angle? 1 formed by the left and right wall surfaces of the outer structure 100 shown in FIG. 2 can be appropriately adjusted.

The light shielding film 120 is formed to match the size of the frame 110 and forms the left and right wall surfaces of the external structure 100 to prevent light from being transmitted to the inside of the external structure 100.

The light shielding film 120 according to the present invention is preferably fabricated to have a waterproof function together with the light shielding function. That is, the light-shielding film 120 has a waterproof function to improve the durability of the light-shielding film 120 and prevent the transporting property from being deteriorated due to heavy weight. According to this embodiment, a white tarpaulin sheet made of polyethylene (PE) is used as the light shielding film 120. [

Such a light-shielding film 120 provides a sheltering effect of sea cucumbers by providing a shade effect in the period including high temperature and hot summer, and the smooth surface of the tarpaulin sheet is not only considering the ecological characteristics of the sea cucumbers which are crawled by suckers, There is a big characteristic.

1, the light shielding film 120 is fastened and fixed to the frame 110 by using a binding strap 130. As shown in FIG. At this time, the light shielding film 120 is installed to have a separation part 124 spaced a certain distance from the pipe 112 located at the left and right lower ends of the frame 110 to provide a passage through which the sea cucumber can move. According to the present embodiment, the spacing portion 124 has a width of about 10 cm.

In this embodiment, the light-shielding film 120 is bound to the frame 110 by using the binding strap 130, but it is possible to use other methods of bonding. For example, the shielding film 120 and the frame 110 may be fastened using a ring or the like.

As shown in FIG. 1, the light blocking film 120 has a plurality of first through holes 122 formed on upper left and right wall surfaces thereof. Accordingly, the seawater can circulate inside and outside of the external structure 100 through the first through hole 122, thereby facilitating the flow of seawater. Then, the light beam is transmitted through the first through hole 122 to the bottom of the bottom so that diatoms, which are food creatures of sea cucumber, can bloom in the floor bottom of the festival farm.

The size of the first through hole 122 is preferably 10 to 15 cm (within a range of approximately 5 to 50 cm), and the second through hole 122 may be formed in a circular shape, a rectangular shape, a triangle shape, a cross shape, Do. Further, 16 to 20 (within a range of approximately 1 to 50) per set may be constituted by one column or a plurality of columns or irregularly.

The reason why the first through hole 122 is formed on the upper portion of the light shielding film 120 is that the sea cucumber is hidden in a space inside the lower side of the light shielding film 120. That is, since the first through holes 122 are formed on the left and right wall surfaces of the light shielding film 120, the light rays passing through the first through holes 122 do not reach the shelter of the sea cucumber. A detailed description of the shelter of sea cucumbers will be given later.

The first inner structure 200 has a vertical cross-section like the outer structure 100, as shown in FIGS. 1 and 2, and is disposed in the inner structure of the outer structure 100. At this time, the distance between the upper surface of the first inner structure 200 and the lower surface of the outer structure 100 is narrowed toward the outer side from the center. That is, the area of the outer structure 100 is formed larger than the area of the first inner structure 200. 2, the angle? 2 formed by the left and right wall surfaces of the first internal structure 200 is larger than the angle? 1 formed by the left and right wall surfaces of the external structure 100. As shown in FIG.

At this time, a narrow space 10a formed between the outer structure 100 and the first inner structure 200 shown in FIG. 2 and a narrow space 10b formed between the first inner structure 200 and the bottom surface form a sea cucumber This is the place to be hiding. In other words, the ecological aquaculture according to the present invention is designed in consideration of the ecological characteristics of the sea cucumbers inhabited between the narrow gaps.

4, the first internal structure 200 includes a frame 210 forming a skeleton of the structure, a food composition film 220 forming the left and right wall surfaces of the structure, And a binding strap 230 binding the periphery of the membrane 220.

Since the frame 210 of the first internal structure 200 has the same technical features as the frame 110 of the external structure 100 described above, the duplicated description will be omitted.

The food composition membrane 220 forms the left and right wall surfaces of the first internal structure 200 to form floating diatoms, adhered diatoms, seaweeds, and floating organic sediments, which are biofilms of sea cucumbers dissolved in seawater of sea cucumber farms. . According to the present embodiment, a parent network or a network is used as the food composition film 220 for providing an adherent substrate. That is, floating and attached diatoms in seawater are caught in mesh. It is also possible to use a shielding film made of a waterproof material such as the tarpaulin sheet as described above as the food composition film 220.

That is, the present invention utilizes the food composition membrane (220) to secure the space required for the high density of sea cucumber, thereby enabling eco-friendly ecology that does not require artificially formulated diets.

As shown in FIG. 4, a plurality of second through holes 224 are formed on the left and right wall surfaces of the food composition membrane 220 to allow the sea cucumbers to move downward. At this time, it is preferable that the second through hole 224 is formed in the middle or lower part of the wall surface. That is, the first through holes 122 of the outer structure 100 are formed on the left and right wall surfaces of the light shielding film 120, so that they are not affected by the light passing through the first through holes 122.

Like the outer structure 100 described above, the food composition membrane 220 has a separating portion 224 having a width of about 10 cm at the lower end of the left and right wall surfaces to provide a passage through which the sea cucumber can move.

As described above, the outer structure 100 and the first inner structure 200 as described above are manufactured in a separated form and are installed in a farm where they are superposed. In addition, when the ecological aquaculture of the present invention is transported using a vehicle or the like, the external structure 100 and the internal structure 200 can be stacked and stacked, which can reduce the transportation cost due to minimization of the transportation volume.

Alternatively, the ecological aquaculture according to the present invention may be manufactured by combining the external structure 100 and the internal structure 200 integrally.

On the other hand, the activity of sea cucumber in ecological aquaculture according to the present invention is as follows. Sea cucumbers are nocturnal due to their ecological characteristics. They prefer dark places, and live in narrow gaps during daytime and then go out to nighttime to feed. And, it is a creature that hibernates in winter (summer sleep) in summer. In other words, sea cucumbers inhabit the shelter provided for the aquaculture during the daytime, and then go out to nighttime to feed.

The sea cucumbers are fed through the first through-holes 122 and the spacing portions 124 of the outer structure 100 and the second through-holes 222 and the spacing portions 224 of the first inner structure 200, The floating diatoms and attached diatoms attached to the light shielding film 120 and the food composition film 220 and the floating organic sediment accumulated in the seaweeds and the light shielding film 120 while traveling on the inside and the outside of the inner structure 200 and the inner structure 200 Eat.

At this time, the ecological aquaculture according to the present invention provided a shade effect in the inner space, so that the sea cucumber could live in habitat and food activity. In particular, by providing a shade effect during the daytime, the food feeding time of the sea cucumber which feeds in the dark at night can be extended to daytime, and the growth speed of the sea cucumber can be greatly improved.

FIG. 5 is a side view of a sea cucumber shade ecological form showing two internal structures. As shown in FIG. 5, it is possible that two or more internal structures 200 and 300 are stacked in the interior of the external structure 100 according to the present invention.

At this time, the distance between the upper surface of the second inner structure 300 and the lower surface of the first inner structure 200 is narrowed toward the outer side from the center, and is disposed inside the first inner structure 200 do. A narrow space 10a formed between the outer structure 100 and the first inner structure 200 and a narrow space 10b formed between the first inner structure 200 and the second inner structure 300, A narrow space 10c formed between the second internal structure 300 and the bottom surface serves as a shelter for the sea cucumber.

FIG. 6 is a cross-sectional view showing a modified vertical section of a sea cucumber shade ecological aquaculture according to the present invention. FIG. In addition, it is also possible that the vertical section of the structure has a shape other than the "? &Quot; shape as described above.

6 (a), the semicircular outer structure 100a and the arc-shaped inner structure 100b are superimposed. At this time, a narrow space 10a 'formed between the outer structure 100a and the inner structure 100b and a narrow space 10b' formed between the inner structure 100b and the bottom surface become shelters of the sea cucumber.

6 (b), the outer structure 100a, the first inner structure 100b, and the second inner structure 100c of a "∩" shape (tunnel type) are stacked. According to this, three hiding places 10a ", 10b ", 10c "can be provided.

That is, the aquaculture structure shown in Figs. 6 (a) and 6 (b) is a form using a curved surface, and the aquaculture structure according to the present invention can be modified into various other forms.

As described above, according to the first embodiment of the present invention, the sea cucumber shading ecological aquaculture can be installed in a festive farm, a terrestrial trough farm or a marine cage farm to provide a shelter for sea cucumbers. At this time, since the aquaculture is installed in the water, the weight is suspended or the pile is fixed on the bottom surface to prevent floating by buoyancy.

According to the present invention, the ecological aquaculture according to the present invention is installed in a range of 400 to 600 (within a range of about 10 to 2,000) per 1 ha in the case of a festival farm, and the installation method is such that the passage of a predetermined space is about 0.3 to 3 m, Or acid predation.
