Description

{Method for poly culture of sea cucumber}

The present invention relates to a method for mixing sea cucumbers.

Sea cucumbers are known to have over 1,500 species of sea cucumbers worldwide. There are about 100 species in China, but there are about 20 species that can be edible. In Korea, sea cucumber is classified into blue sea cucumber, red sea cucumber, and black sea cucumber. The Korean sea cucumber ( Stichopus japonicus ) belongs to the genus Aspiodchirotida, the sea cucumber (Stichopodidae), and the sea cucumber (Stichopus). In Korea, about 14 species are known to be inhabited. Among them, Stichopus japonicus is the most important species for industrial and economic reasons .

Despite the fact that Korea's fisheries industry has abundant sea resources such as the world's five largest tidal flats, the technology of molluscs and invertebrates, including shellfish, is a green growth and high value-added industry. It is at a mild level. Sea cucumbers are obstacles to industrialization because high-income varieties and mass culture technology have not been developed in Korea, China and Japan. The technology level of sea cucumber cultivation in Korea is in the stage of mass production of artificial seedlings and sperm culture, but the development of mass production technology such as festive ceremony and aquaculture culture with high seed demand is insufficient.

Sea cucumbers are called sea ginseng and their preference as health and wellness food is gradually increasing. Consumer demand for high quality aquatic products is also increasing. It is used as anticancer substance in North America, and as hip arthritis, diabetes, epilepsy, eczema, hypertension, and pertussis medicine in China and Asia. Especially in the Chinese market, it is very valuable as an export strategy variant because it is a high-priced seller.

Sea cucumbers are distributed along the entire coastal area of Korea affected by seawater. Outside of the country, it is distributed widely in the northeastern Pacific Ocean, coastal waters of Sakhalin, Alaska, Hokkaido, Japan, Yellow Sea, Balhae Bay, and East China Sea. The sea cucumber (sea cucumber) is a sandy or sandy area, which is connected with rock, small stones, pebbles except pure pearl area. It is distributed more widely than red sea ginseng, many. Especially when they are young, they live in a place where there is a lot of seaweed in the sea or in the reef area with red sea gins,

The production of wild sea cucumbers in Korea decreased by 2,491 tons in 1990, 1,419 tons in 2000, and 833 tons in 2002, and recently, a small seed sowing by artificial seedling has been recovered slightly, 1,136 tons in 2005, 1,136 tons in 2007 2,936 tons, and the highest level in 2010 was 2,687 tons.

Korean Patent Registration No. 10-0915037 (Patent Document 0001) is an invention relating to a method for complex-type production of fish and sea cucumber in which marine pollution is prevented and an apparatus therefor. In detail, the above-described sea cucumber aquaculture apparatus includes a fish culture tank having seawater and a fish which are cultured, an outlet for discharging surplus feed and excrement deposited on the floor by discharging it to the seawater, And a sea cucumber culturing tank connected to the fish culture tank and having a room for culturing the sea cucumber, in which excrement and surplus feed attached to the sea water are deposited. It is advantageous that the cost of sea cucumber cultivation can be reduced and the efficiency of sea cucumber cultivation can be doubled, and marine pollution can be prevented by cultivating sea cucumber using the living matter generated as a byproduct of fish culture through the apparatus. However, Patent Document 0001 has a problem that the fish is cultured in the aquarium of the land, and the sea cucumber is performed in the sea cucumber cultivation in the offshore, and the water depth is low and the wave is broken, which is not suitable as a habitat for sea cucumbers. If the sea cucumber is placed in an area suitable for the sea cucumber, the cost and complexity of the structure connecting the fish cucumber and the sea cucumber are increased.

Korean Patent Laid-open Publication No. 10-2015-0051211 (Patent Document 0002) discloses a technique for providing a new method of releasing a sea cucumber seedlings in which sea cucumber seedlings released into the sea can be safely settled and stayed in a discharge area using artificial fish specimens dedicated to sea cucumber . In order to solve the above-mentioned problem, the present invention has made a protected habitat for sea cucumber seedlings using artificial fish specimens for sea cucumbers manufactured by Korean Patent No. 10-1116724. The habitat frame is Korean Patent No. 10-1116724 ] [ECO-SC1001 Agriculture, Forestry and Fisheries Ministry of Fisheries Testing] We have placed ECO-SC1001 on the upper and lower left and right sides of the sea cucumber for the sea cucumber and cover the same ECO-SC1001 with the lid. The sea cucumber seedlings put into the habitat frame by putting the sea cucumber seedlings into the habitat frame designed for a long time by the test in the actual sea are not washed away by the strong algae but are able to stay and grow in the habitat safely until the self- . However, the method of releasing seedlings according to patent document 0002 does not differ greatly from the habitat environment of natural sea cucumber unless artificially fed or not, so that the growth rate and productivity of sea cucumber are not significantly different from those of natural sea cucumber. It is used only for the purpose of stocking and aquaculture.

[0006] Aquaculture 275 (2008) 124-13 (Non-Patent Document 0001) conducted a study on the growth of sea cucumber in the lower part of the oyster farm, specifically, The water cistern was placed in a 2.5 meter (8.5 m) depth of the bottom of the sea cucumber, and the sea cucumbers were released into a sea cucumber breeding box. The sea cucumbers were released for about 10 months and the water content, organic carbon, , Size) were measured. However, the above measurement was carried out for a period of only 10 months, and the period of 10 months was short in terms of the ecology of the sea cucumber, and it was difficult to confirm the significant effect of the sea cucumber growth on the growth effect of the sea cucumber. In addition, the sea cucumber breeding box in which the sea cucumbers have been released is composed of a plastic material (PVC) on the lower surface, and the side and upper surface of the sea cucumber breeding box is composed of wire panels of 0.625 cm mesh size, There is a big difference from the aquaculture environment. In addition, culturing the sea cucumbers by connecting the trays to a farm is inadequate to cultivate large amounts of sea cucumbers, which can not be applied to commercial sea cucumber cultivation.

Accordingly, the present invention has confirmed that the method of mixing sea cucumber with sea cucumber can promote the growth of sea cucumber, improve the density of sea cucumber culture, and improve bottom quality, thus completing the present invention.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings. However, the present invention is not limited to or limited by the exemplary embodiments. Like reference numerals in the drawings denote members performing substantially the same function.

The objects and effects of the present invention can be understood or clarified naturally by the following description, and the purpose and effect of the present invention are not limited by the following description. In the following description, well-known functions or constructions are not described in detail since they would obscure the invention in unnecessary detail.

Hereinafter, a state in which a plurality of artificial ear seconds are combined is defined as an artificial ear superstructure, an area in which an artificial ear superstructure is disposed, and an artificial ear superstructure disposed in the area, and a plurality of artificial ear superstructures Is defined as an artificial fish sanitary facility.

A method for mixing sea cucumbers according to an embodiment of the present invention includes preparing sea cucumbers (step 1) of a credit artificial fish candle; The sea cucumber is provided with a step of providing a credit artificial fish on the underside of a farm under cultivation of at least one species selected from the group consisting of oysters, mussels and mussels (step 2); And the step of releasing the sea cucumbers (step 3) of the sea cucumber in a credit artificial perch.

Hereinafter, the method of mixing the sea cucumber according to the present invention will be described in detail.

As shown in FIG. 1, the sea cucumber mixed form is a method for cultivating sea cucumbers by providing a credit artificial fish candle on the bottom surface of the lower part of the cultivation hatchery such as oysters, sea cucumbers or sea squirts. The body of organic matter, excreta and marine life is the principle of food for sea cucumbers. In addition, the sea cucumber is an eco-friendly aquaculture technology because it absorbs and decomposes organic matter and has a low quality improvement effect. Compared to the naturally cultured sea cucumber, the cultured sea cucumber is characterized by a high growth rate due to the abundant feeding effect provided by the aquaculture farm. Therefore, the method of mixing the sea cucumber according to the present invention is characterized in that efficiency and productivity are improved compared with the sea cucumber monoculture system or the sea cucumber natural form. On the other hand, the sea cucumbers are fed mainly diatoms, and when they grow more than 3 cm, the sea cucumbers are consumed organic materials, seaweeds, and fish and shellfish excrements. Due to the feeding characteristics of these sea cucumbers, it is difficult to cultivate them using feeds. In addition, the method of mixing sea cucumbers according to the present invention does not require a separate feeding of sea cucumbers, so that feeding cost and labor power are reduced as compared with the method of ending sea cucumber.

Generally, oysters and sea squirts are composed of pearl (nicholas, silt) and the bottom of the sea floor is inadequate to live in sea cucumber. Suitable for sea cucumbers is a mixture of rock, gravel, and sandy, with a pearl content of less than 10%, and a source of food sources such as seaweed. In addition, sea cucumbers move to a place where the water depth is deepened when the sea water temperature rises, and to the shallow water depth when the sea water temperature is low. Therefore, the sea cucumber is easy to grow where the sea floor is inclined. Therefore, it is possible to utilize the organic matter generated from oysters and the like as a food. However, since the environment of the sea floor is inappropriate for the sea cucumber to live, when the sea cucumber is discharged to the bottom surface of the oyster or mermaid farm, Do not. In order to solve this problem, the present invention prepares a credit artificial fish candle for sea cucumber.

Step 1 according to the present invention is a step of preparing sea cucumbers for preparing artificial fishes for credit, preparing sea cucumbers capable of growing, feeding, moving, excretion, breeding and hatching. Hereinafter, an artificial speech unit will be described with reference to the artificial speech unit shown in Figs. 4 to 6 of the present invention.

Fig. 2 shows the morphology of the sea cucumber. Referring to FIG. 2, it can be seen that the sea cucumber has a strong habitat in the concave part of the stair-shaped artificial fish.

Sea cucumbers generally live in rocks, pebbles, and sandy areas of outer waters, and tend to favor corners and corners. In the method for mixing sea cucumbers according to the present invention, the artificial fish supernatant of sea cucumber should be prepared in consideration of the environment for the sea cucumber.

The sea cucumber of the present invention is a fishery facility that protects and cultivates sea cucumber as an artificial structure used as a credit artificial fish. Artificial fishes play a similar role to natural rocks. Considering the ecology of sea cucumbers, it is necessary to artificially create the habitat environment preferred for artificial fishes and to cultivate sea cucumbers at high density by laminating artificial fishes. to be. These artificial fishes are good habitats for algae that play a big role in the marine ecosystem. Abundant algae become good food for fishes and shellfish, and become good spawning ground for fish. In addition, artificial fishes protect against intense waves (swells) and ocean currents, create vortexes, and provide rich dissolved oxygen and micro-plankton, making fish and shellfish a good resting place. Artificial fish is not necessarily made of rock, gravel and sand, but may be made of plastics such as synthetic resin depending on the application. However, when using synthetic artificial reefs, the environmental pollution must be considered.

Artificial fishes are used as a shelter, an eating place, an underwater place, a spawning place and a breeding ground for young sea cucumbers. Sea cucumbers generally have a friendly response to artificial fishes, and red sea gins are known to exhibit strong stomach uptake in artificial fishes. It can be assumed that the habit of this sea cucumber is due to backlighting and sensibility. The upper part of the artificial fish is generally characterized by regular grooves and protrusions, which enlarges the surface area of the artificial fish and immerses the immersed body in the fine groove to inhibit the movement of the immersed body by waves and algae To be used as food for sea cucumbers.

In addition, it is advantageous that artificial fishes have a limited habitat area of sea cucumbers in a natural environment and can increase the density of sea cucumbers in a unit area by layering multi-layer artificial fishes. In addition, the simplicity of adding or subtracting artificial fish candy can be used to control the density of organisms to be cultivated.

Wherein the sea cucumber has a frame having a curved arch structure for supporting an upper load of the opening and having an opening in which the sea cucumber is inhabited, and a sea cucumber protruding along the longitudinal direction of the frame on the outer circumferential surface of the frame, A plurality of protrusions are formed on an outer circumferential surface of the frame, and the protrusions are formed by inserting a part of a frame of a credit artificial fish into a laminate So that they are spaced apart from each other.

Hereinafter, the sea cucumber used in the method of mixing sea cucumber according to the present invention will be described in detail on the basis of Figs. 4 to 6 as an example of the credit artificial fish.

FIG. 4 shows a sea artifact per second according to an embodiment of the present invention.

In this embodiment, sea cucumber is a fishery facility that protects and nurtures aquatic organisms with an artificial structure as a credit artificial fish. Sea cucumbers play a similar role to natural rocks in the artificial sea cucumbers. Considering the ecology of sea cucumbers, the sea cucumbers artificially form the preferred environment for sea cucumbers in the artificial sea cucumbers and sea cucumbers, It is the purpose of the sea cucumber to introduce the credit artificial fish supernatant. These sea cucumbers are good habitats for seaweeds that play a large role in the marine ecosystem, and rich seaweeds are good food for fishes and shellfish, and become good spawning grounds for fish. In addition, the sea cucumber is a credit artificial fish that protects against intense waves (swells) and ocean currents, creates vortexes, and provides rich dissolved oxygen and micro plankton, which makes it a good place for seafood.

Referring to FIG. 4, the sea cucumber may be provided as a frame 11 including a plurality of protrusions 13 protruding from the outer circumferential surface thereof. The frame 11 according to the present embodiment can define the concave portion 15 as a space separated between the projecting portion 13 and the projecting portion 13 as a plurality of the projecting portions 13 are formed.

The frame 11 may have an opening 30 in which the sea cucumber may reside and may have a curved arch structure to support the upper load of the opening 30.

The arch structure refers to a curved shape in which the opening 30 is secured and a considerable load can be supported by compressive stress. Through this, the arch structure prevents the tensile stress from acting on the structure. All loads acting in the downward direction from the top of the arch structure will act as compressive stresses. It is strong against compression in rocks, cast iron, concrete, etc., but it is advantageous for weak materials in tensile, shearing and twisting. Therefore, sea cucumber can be made of concrete material to have strong resistance to corrosion and stress in underwater environments.

The opening 30 will be described in detail with reference to the shape of the frame 11 described below.

The frame 11 is an arch structure in which the lower surface is opened and the longitudinal section of the ∩ shape is elongated in the longitudinal direction and the legs 11a (Fig. 6) supporting the frame 11 are spaced apart from the spacing space 15 of the projections 13. Fig. And may be laminated on the outer circumferential surface of the other frame 11. [

The above-mentioned longitudinal direction means a direction parallel to the axial direction of the frame 11. Accordingly, the legs 11a (Fig. 6) can be understood as regions corresponding to both ends formed along the circumferential direction of the frame 11 extending along the axial direction. As described above, the frame 11, which is formed by bending a plate-shaped object having a thickness, can be understood as a semi-cylindrical shape in which the inside in the circumferential direction is removed. Thus, the opening 30 may mean the inner circumferential surface of the frame 11 and the space formed by the other structures.

The leg 11a according to the present embodiment does not mean a component added to the frame 11 and includes a frame 11 capable of performing a function of abutting the substructure to support the frame 11, Lt; / RTI >

In this embodiment, the frame 11 emphasizes the structure of the legs 11a (Fig. 6) so that it can be fixed easily at the time of insertion, so that the underside can have an open structure. The spacing space of the projections 13 defined by the recess 15 on the outer surface of the frame 11 also engages other structures that do not have the same dimensions as the width of the frame legs 11a .

The frame legs 11a (Fig. 6) can be easily inserted by minimizing the bottom surface and the friction surface of the knee. In addition, the frame legs 11a (FIG. 6) can perform the fixing function through the frictional force generated from the bottom surface and the pressure acting on the bottom surface when the sea cucumber hide sinks on the bottom surface of the knee.

As described above, the frame 11 having the open bottom structure can provide a structural characteristic so that the sea cucumber can easily ingest a body of fish or shellfish present on the bottom surface or organic matter in the soil.

5 is an enlarged view of a protrusion 13 according to an embodiment of the present invention.

Referring to FIG. 5, a plurality of access holes 130 are formed on the surface of the protrusion 13.

The protrusion 13 protrudes along the longitudinal direction of the frame 11 on the outer circumferential surface of the frame 11 and an access hole 130 penetrating through the frame 11 is formed so that the sea cucumber can be inserted into the opening 30 . A plurality of protrusions 13 are formed on the outer circumferential surface of the frame 11 and can be spaced apart from each other so that the legs 11a (Fig. 6) of the frame can be inserted.

In this embodiment, the projecting portion 13 may have a flat cross-section so that the entrance and exit holes 130 are formed. The protruding portion 13 may be provided with a sufficient space for the sea cucumber to live in the spaces between the both side surfaces and the protruding portions 13. The protrusions 13 may interfere with fishing due to the small unauthorized trawler trawl or fishing trawl fishing in coastal fishing grounds due to the nature of the structure.

The protrusion 13 may have an inner diameter of 10 to 20 cm.

In this embodiment, the access hole 130 can be used as a flow path for organic matter and inorganic matter and as a passage for sea cucumbers. Sea cucumbers have a strong appetite and active activity at water temperatures below 17, stop eating when they are above 17, and sleep in the summer when they are above 25. Generally, the sea tear adults can grow to 10 to 30 cm in length and 10 to 15 cm in thickness, and weigh about 200 to 300 g. Therefore, in order to protect the sea cucumber from resting in the inner space, the size of the access hole 130 is required to isolate the sea cucumber's natural enemies and not to restrict movement and stealth of the sea cucumber. . The entrance hole 130 may be formed to have the same inner diameter from the surface of the projecting portion 13 to the opening 30 in the frame 11.

In this embodiment, the access hole 130 is located on the projection 13 and needs to be noted for its function. Sea cucumbers generally tend to prefer corners or corners. When the access hole 130 is located in the concave portion 15, the sea cucumber is inhabited in the concave portion 15 at a high density, and the penetration into the access hole 130 can be blocked. In addition to this, it is difficult to protect the sea cucumber from enemies, as the sea cucumbers reduce the amount of dissolved oxygen in the openings 30 formed in the interior of the credit artificial fish and reduce the effect of providing micro-plankton, .

The protruding portion 13 may be formed extending from the inner peripheral surface of the frame 11 inward.

Specifically, the projections 13 formed to extend outward from the outer circumferential surface of the frame 11 and the projections can be formed at positions corresponding to the frame 11. In this way, the surface area of the inside of the frame 11 can be increased to improve the habitat area of the sea cucumber.

And may be formed extending inward from the inner circumferential surface at a staggered position with the protruding portion 13 formed to extend outward from the outer circumferential surface of the frame 11. [ In this case, the surface area of the inside of the frame 11 increases and the access hole 130 is formed shorter than the frame 11 having the protruding portion extending to the corresponding position, so that the sea cucumber can easily access the frame 11 .

As such, the projecting portion 13 can be elongated with respect to the outer peripheral surface and the inner peripheral surface of the frame 11, and the position thereof can be selectively changed.

FIG. 6 shows a sea cucumber according to an embodiment of the present invention.

The sea cucumber according to the present embodiment may be arranged such that the first artificial cucumber of the first sea cucumber and the second artificial cucumber of the second sea cucumber are arranged in parallel adjacent to each other to be in contact with the sea floor. In addition, the first and second sea cucumbers may be installed in multiple stages by inserting the frame legs 11a between protrusions formed on the outer circumferential surfaces of the respective credit artificial fish secs. At this time, the first and second sea cucumbers may form the first living space 31 with the opening 30 spaced apart from the bottom of the credit artificial fish and the sea floor. In addition, the frame 30 inserted between the frame 11 and the first and second sea cucumbers may form a second living space 33. In this embodiment, in order to describe a state in which a plurality of frames 11 are stacked, the first and second sea cucumbers define credit artificial seconds as terms for describing structures different from the frame 11 to be inserted.

The projections 13 may not be formed in the center line in the longitudinal direction on the outer peripheral surface of the frame 11 so that the legs 11a of the other frame can be inserted and stacked at the center of the outer peripheral surface of the frame 11. [

As a result, the artificial fish prepared with a certain standard size can be arranged at equal intervals to enable repeated laminating. In detail, a plurality of artificial fish seats in contact with the sea floor can be arranged in parallel to form a single stage. Thereafter, the two-stage artificial fish candles can be arranged in parallel so that the frame legs are correspondingly inserted into the center of the outer peripheral surface of the adjacent first-stage artificial fish candle. An additional laminate structure such as a three-stage or a four-stage can be formed in the same manner. Therefore, excluding the formation of protrusions on the center line in the longitudinal direction on the outer circumferential surface can be understood as a condition for inducing easy stacking of artificial fish secs of the same size.

In addition, the protrusion 13 at the position closest to the frame leg 11a can prevent the sea cucumber from eroding the credit artificial ear seconds. 4, the outer circumferential surface and the inner circumferential surface of the frame 11 are provided in the form of a saw tooth due to the plurality of projections 13. [ In this case, the side projections 13 in the direction of the frame leg 11a that come into contact with the ground can prevent the frame 11 from completely sinking into the load.

More specifically, although the stacking of the artificial fishes can improve the load and accelerate the encroachment of the frame 11 located at the lower part, the above-described lateral direction protrusion 13 rubs against the ground to disperse the stress, It is possible to resist the settling of the frame 11.

The projections 13 can be spaced apart from each other by more than the width of the frame legs 11a.

In this regard, the space spaced between the projections 13 can be understood as the recess 15. Generally, sea cucumbers have a friendly response to artificial fish. Especially, red sea ginseng is known to exhibit strong stomach uptake in artificial fish. Therefore, a large amount of sea cucumber can be formed and stuck in the concave portion 15. Particularly, in the proposed sea cucumber of the recessed portion 15, the portion 15a where the leg 11a of the frame to be positioned at the time of stacking of the credit artificial fish secures is wider than the width of the frame for stable insertion of the frame leg 11a Space can be maintained. Through this, an additional opening 30 may be formed between the upper artificial ear and the lower artificial ear. Therefore, it is possible to easily form additional space for accommodating the sea cucumber growing in the seabed.

In particular, the growth of sea cucumbers depends on the density of the species in different conditions. If the sea cucumbers contain less than 10,000 individuals, the growth rate of each individual can be improved, but economical problems due to the low density can occur. On the other hand, in the case of exceeding 15,000 individuals, the density of the individual becomes higher, the growth rate of the sea cucumber is lowered, and the survival rate is also affected. Therefore, the culture method according to the present invention is advantageous in that it can increase the number of cultured sea cucumbers in the same unit area by controlling the density of sea cucumbers by utilizing a structure in which artificial fish candies can be easily stacked and extended to accommodate an appropriate number of individuals have.

Step 2 according to the present invention is a step of installing a credit artificial fish candle on the seabed surface of the bottom of the farm where the marine organisms are cultured. The artificial fish candle for sea cucumber cultivation is placed in the lower part of the farm where the by- .

At this time, in order to utilize the organic matter generated from the farm site efficiently, it is desirable to provide artificial fishes in the area corresponding to 50 to 90% of the farm site area among the sea floor below the farm site. If the area is less than 50%, there is a problem that the sea cucumber cultivation space becomes insufficient. If the area exceeds 90%, the organic matter generated from the farm is floated by the tidal current and the like, There is a problem that it can not be utilized.

In general, suitable for sea cucumber habitat is a mixture of rock, gravel, and sandy, has a pearl content of less than 10%, and is rich in food sources such as seaweed. The water temperature suitable for growth is 10 ~ 14 ℃, salinity 28 ~ 34 psu, dissolved oxygen 5.0 mg / L and flow rate 0.2 ~ 0.4 m / s. Constructed oysters and barnacles are unfavorable conditions for sea cucumbers. In addition, since the bottom surface of oysters, mussels, and mussel farms is generally flat, it is a disadvantageous environment in the form of sea cucumbers that prefer a sloping environment. Therefore, when the sea cucumbers are cultured on a general oyster farm or on the submarine surface of the sea squirt farm, there is a difficulty in culturing the sea cucumber. In order to solve such a problem, the present invention includes a step of installing sea artificial fish seaweed on the sea floor in order to facilitate the sea cucumber culture in the submarine bottom surface of a marine biological farm such as a cave, a sea urchin, and a mussel.

That is, when the sea cucumber is cultured on the sea floor of a cave, a sea anchor, or a mussel farm, the food source for sea cucumber cultivation can be enriched and the marine environment can be improved. However, such a sea cucumber, The problem was that cotton was a disadvantageous environment for culturing sea cucumbers. The present invention solves the above problems, and thus it is possible to supply a large amount of food for the sea cucumber culture, to improve the marine environment, and to efficiently cultivate the sea cucumber.

The creatures that are suitable for aquaculture are oysters, mussels and mussels. It is characterized by the high density of the organisms to be cultivated. The higher the density of the marine organisms cultivated in the sea, the more the growth of the sea cucumbers is promoted by discharging more living matter. In Korea, oysters, minks, and mussels are being cultivated using the method of water-eating. In addition, sea cucumbers feed on the byproducts of aquaculture farms to improve bottom quality and improve the marine environment. As a result, sea creatures such as marine creatures that are inhabited by marine organisms can have an additional effect on marine culture.

The sea cucumber of step 2 is preferably carried out in such a manner that the credit artificial fish is placed on the sea floor of 5 to 15 meters in depth.

The arrangement of artificial fishes is affected by depth of water. Therefore, it is recommended to avoid the breakwater in the sea basically. It is judged as a way to maximize the effect of the artificial fishery facility by providing the boundary with the flat sandy rocks. Ensuring three times as much design fatigue as the design target will provide effective stability. These artificial fisheries facilities must be designed in consideration of the characteristics of the sea area, and it is especially important to design a comprehensive layout and facility considering the feeding, moving, excretion, circulation and density of the sea cucumber.

If the artificial fish plant of the sea cucumber is installed at a depth of less than 5 meters, it is close to the seawater surface and frequent changes in water temperature due to the day-to-day variation occur. It has a bad influence. In addition, if the water depth is low, there is a possibility that the vital materials discharged from the farm may be moved by the seawater algae movement, so that the merits of the sea cucumber mixing style may disappear. As the depth of water and / or debris emitted from farms increases, the reach of organic matter tends to decrease. Therefore, if the artificial fish plant of sea cucumber is installed at a depth of more than 15 meters, the reach rate of the organism discharged from the farm is lowered, and the growth rate of the sea cucumber is also difficult to obtain a large increase. In addition, the sea cucumber is increasingly vulnerable to the facilities, maintenance and management of artificial fishery facilities and the harvesting of sea cucumbers as the depth of credit artificial fishes deepens.

In the mixed and mixed culture method according to an embodiment of the present invention, it is preferable that a distance of 10 to 100 meters is provided between different artificial ear superstructures when installing the artificial ear candles.

The meaning of the artificial super structure area is as defined above. Sea cucumbers are based on omni-directional movement lines of sea cucumbers. The artificial fishery structure area is spaced 10 to 100 meters apart from each other, so that it is economical for the artificial fishery structure area and can form a space between the artificial fishery structure area and the artificial fishery structure area.

If the distance of the artificial fishery structure area is less than 10 meters, the sea cucumber's aggregation on the artificial fishery structure area falls and the efficiency of aquaculture is lowered. If the distance of the artificial reef structure area exceeds 100 meters, the size of the aquaculture farm will increase and the management cost of the sea cucumber farming may increase.

Arrangement of artificial fishery facilities must be designed considering the characteristics of the sea area. Especially, comprehensive layout and facility design considering the eating, moving, excretion, circulation and density of the sea cucumber in the sea area is important. Especially, if the sea cucumber culture system using the facilities capable of limiting the movement of sea cucumber in the sea floor and artificially inducing the copper wire is applied in parallel, the effect can be maximized.

The method of the present invention is preferably capable of accommodating 10,000 to 15,000 individuals of sea cucumber, but the number of sea cucumbers is not limited thereto.

The growth of sea cucumbers depends on the density of the species in different conditions. If the aquaculture method accepts sea cucumbers below 10,000 individuals, the growth rate of each individual can be improved, but economical problems due to low density cultivation can occur. If the aquaculture method is carried out in excess of 15,000 individuals, the density of the individual is increased, the growth rate of the sea cucumber is lowered, and the survival rate is also affected. The method of mixing sea cucumbers according to the present invention is capable of culturing at a density higher than the natural state because the food of abundant sea cucumbers is provided by a large amount of living matter discharged from the heterogeneous organisms cultured in the farm. In addition, when the sea cucumber is used as a habitat for sea cucumbers, for example, artificial fish cucumbers can be layered in multiple layers to increase the density of sea cucumbers.

It is preferable that the step 2 further includes the step of setting up the palm before the establishment of the artificial fish candle.

The mixed culture method according to the present invention is characterized in that artificial fish seaweeds of sea cucumber are provided on the sea floor. If the sea floor of the mixed farm where the facility is to be constructed is mild or if it is muddy, there is a possibility that the artificial fish meal is eroded, and measures are needed to prevent it. For the above reasons, the artificial fish may be provided with a light weight material. In the sea cucumber mixing method according to the present invention, the sea cucumber is installed in advance in the form of net before installing the credit artificial fish candle on the sea floor, If the sea cucumber is equipped with a credit artificial fish candle, the sea cucumber can prevent the credit artificial fish from being eroded down to the bottom of the sea.

In step 3 according to the present invention, the sea cucumber is a step of releasing sea cucumber in a credit artificial perch, and discharging the sea cucumber to be cultured to the surface and inside of the credit artificial perch.

In the step 3, the sea cucumber may be at least one of juvenile and adult sea cucumbers, and it is preferable that both juveniles and adult cucumbers are discharged at the same time.

The larval stages of the sea cucumbers grow in the order of fertilized eggs → cysts → Auricularia → Doliolaria → Pentactula → juveniles in order, fertilized eggs, During the larval stage of the larvae and dolia laria, they live in the penticulla larvae and attach to the rocks and stones in the form of sea cucumbers. They grow by eating single-celled microalgae and diatoms that are attached to rocks and stones.

The purpose of the culture of sea cucumber is to grow larvae juvenile larvae to increase the number of inhabitants in the farm, and to cultivate adult sea cucumbers for harvesting purposes. The annual growth of sea cucumber is about 6 ㎝ (about 15 g), about 13 ㎝ (about 80 g) and about 18 ㎝ (about 180 g) about three years a year. The sea cucumber is not fertile until approximately one year. For the above reasons, it is preferable that the sea cucumbers for one year or less are not harvested and that for sustainable sea cucumber cultivation, the juvenile sea cucumbers for harvesting and the adult sea cucumbers for harvesting are simultaneously discharged.

Intermediate cultivation stages of growing sea cucumbers and sea cucumbers after sea cucumber larvae emerged have been mainly carried out on land farms. This is because when the young sea cucumber is sown early on the sea, the survival rate is low due to difficulties in adapting to the natural environment such as feeding activity and receiving enemy attacks such as sea birds easily. However, when the intermediate cultivation stage of juvenile sea cucumber is carried out on land, the survival rate at the early stage of release is increased, but it is costly to manage copepods, parasites or pathogens. In order to relieve these copepods and to inhibit various parasites and pathogens, There is a problem that requires bathing. However, the method of mixing the sea cucumber according to the present invention does not require the seedling to be cultivated on the land farm, and it is advantageous in that it can be sown directly to the sea cucumber hiding place according to the present invention and can avoid predators in the hiding place.
