Description

{SUBMERSIBLE CAGE FOR ABALONE FARMING}

The present invention relates to a submerged abalone cage aquaculture device, and more particularly, to a submerged abalone cage aquaculture device for submerging submerged abalone cages in a submerged state so that an abalone cage is prevented from being influenced by a current formed in water such as an ocean current, a typhoon, And to an increased sinking abalone cage aquaculture device.

Abalone, which has been loved for its excellent texture and nutrition, has been continuously increasing in demand despite its high price. Abalone, which is loved by people not only in Korea but also in the world, belongs to the Haliotidae and Haliotis , and lives in coasts of temperate, tropical and subtropical regions all over the world. Haliotis discus hannai , Haliotis discus discus , Haliotis madaka , and Haliotis gigantea are the most abundant species in Korea. have.

Abalone is known to be effective for prevention of obesity, protection of liver, recovery of fatigue, protection of eyesight and prevention of myocardial infarction because of high protein content and low fat content. Abalone, which is regarded as a high quality aquatic product, is called a shellfish emperor. It is traded at a high price among aquatic products, and its value is recognized because it is increasing not only in domestic but also overseas like China and Japan. However, the amount of offshore abalone has been decreasing due to overfishing of overcrowded biomass and industrialized urbanization, while the abalone aquaculture industry occupies 53% of the total shellfish production of 560.3 billion won in 2014, It is growing.

As abalone farming techniques were established in the 1980s, abundant farming methods were developed from choral to cage farming to terrestrial farming. Particularly, sea cage methods are being used to make cages in the sea, and to feed seaweed and kelp in the seaweeds and artificial houses.

Recently, however, the fishery environment of marine caged fishery, which is the most abalone fishery, is getting worse. The marine cages, which are installed in the offshore waters around the West Sea and the South Sea, are experiencing worsening of the aquaculture environment due to poor distribution of seawater due to erosion, seaweeds used as feeds, and compound feed residue. As a result, the mortality rate is high and productivity is rapidly decreasing.

In addition, aquaculture facilities are damaged due to weather changes such as typhoons that come from the seasons. The marine cage aquaculture facility is a structure made by enclosing a mesh in a frame with a skeleton below the water surface. These structures are connected at regular intervals, and the upper frame including the scaffolding is connected to a so- And the lower abalone part is configured to be located 2 to 3 m below the surface of the water. These maritime cage devices are rope-secured to the sea floor.

Under the web of the abalone farming area, abalone attaches to the structure which can grow, and when feed such as seaweed, kelp, etc. is supplied, the food waste or abalone excrement passes through the net and is released to the bottom of the sea floor. Most of the abalone marine cage facilities are installed in dense waters near the sea, making it difficult to circulate clean water because the birds are stagnant and the communication is not smooth. As a result, the amount of dissolved oxygen in the farms is also lowered, which deteriorates the farming environment. In other words, it is inevitable that the aquaculture receives the damage of environmental pollution by the aquaculture facility.

In addition, the cage structure floated on the sea by styrofoam or the like connected with the certain standard is shaken easily by high waves and wind, and it is overturned or swept away by typhoon. In fact, the typhoon 'Mi-par' in 2011, the typhoons of 'Volaben' in 2012, and 'Denbin' have wreaked havoc on abalone farms in Wando area, and have suffered hundreds of billions of damages including caged aquaculture facilities and abalone species. In addition, after the typhoon passed, our abalone and destruction cascades were pushed to the shore and piled up, causing secondary damage.

Recent global climate change has been accompanied by an increase in high waves due to rising sea level due to warming and the possibility of typhoons that directly affects offshore cage augmentation is becoming more and more disadvantageous to marine cage culture . Therefore, it is urgent to develop a subsidence culture method for abalone cultivation which has value as a commodity in order to prepare for natural disaster and cultivate for many years.

Hereinafter, the present invention will be described in detail with reference to specific examples.

1 is a perspective view of a submerged abalone cage aquaculture apparatus according to the present invention. The present invention is characterized in that a space defined by a frame (110) surrounding a bottom surface, a side surface, and a top surface of a certain area is surrounded by a netting portion (120) ). A plurality of the abalignment style layers 100 are continuously connected to each other to form a closed polygonal or circular shape and form a through hole 600 at the center. The lower abdominal style layer 100 is provided with a side frame 110 The space portion is connected to the cage through hole 600 to form a current communication layer 300 formed so that the water flow can communicate freely up and down or right and left. A multifunctional layer 400 is formed below the current communication layer 300. The multifunctional layer 400 is separated from the abalone type layer by the current communication layer 300. The multi- And a supporter (500) for preventing intrusion of biological substances and inflow of contaminants is formed on the bottom surface of the cage.

And the upper, lower, and side surfaces of the overturning layer 100 are surrounded by the mesh 110 by the frame 110 formed on the upper, lower, and side surfaces. Therefore, since the ocean current is transmitted through the mesh of the mesh part 120 at the seabed and clean oceans including oxygen are supplied, it is placed in the culture space of the abalone style and the abalone style.

An entrance (not shown) is formed on the upper side or the lateral side for feeding or for feeding or collecting abalone, thereby facilitating the management of the aquaculture. The doorway can be formed so that one side of the mesh portion 110 on the upper side or the side surface is fixed by the door fixing portion 130 and can be opened and closed. The form cage 140 can be further inserted into the abalone style layer 100 of one aquaculture zone unit 700 so that harvesting and harvesting of aquatic organisms are facilitated.

When moving aquaculture from a cage, it is convenient to move the cage in a cage (140) unit, thereby preventing the time required for removing the abalone from being delayed. It is convenient to keep the population among each aquaculture zone constant It is easy to do. The form cage 140 can be divided into a plurality of sections in one abalone style layer 100 as required.

In addition, in the abalone culture layer (100), the abalone shelter is inserted to increase the number of abalone cultivated by increasing the area of abalone to be cultivated, You can perform the form. In addition, by inserting different types of shelters into the abalone type layer 100, other aquatic organisms such as octopuses other than abalone may be cultured. The mesh size of the mesh part 120 and the type and shape of the shelter can be changed according to the type of organism to be cultured.

At the lower part of the abalone type layer 100, the sea cucumber cultivation layer 200 can be formed in which the abalone cultured in the abalone type layer 100 is fed and the debris and waste of the food are downwardly accumulated. The upper surface of the sea cucumber cultivation layer 200 is formed as a bottom surface of the abalone type layer 100 so that the substance generated in the abalone culturing process can move to the sea cucumber cultured layer 200, And is separated from the outside by the mesh portion 120 like the mesh portion 100.

The abalone and sea cucumbers are known as species capable of co-culturing in aquaculture. The sea cucumber cultivation bed 200 is provided with a sea cucumber culturing tray 200 in which cultured sea cucumbers are fed and niches capable of concealing the body can be stored in the sea cucumber cultivation bed 200, And a floor surface free of through holes can be formed to facilitate the culture of the sea cucumber. In addition, it can be formed as a drawer so that the sea cucumber cultivation layer 200 can be inserted into the frame 110 to facilitate the stocking of ginseng and the recovery of sea cucumbers. In the sea cucumber culture layer, it is inappropriate to make the lower part a mesh part, and a tray having a constant height on all sides can be added on the mesh part.

A current communication layer 300 is formed below the abalignment type layer 100 or the sea cucumber cultivation layer 200. The side of the current communication layer 300 is opened so that the current can freely communicate. In addition to flowing seawater through the ocean current layer (300) to prevent seawater from stagnating in the aquaculture area and to provide fresh ocean currents, it is also possible that ocean currents collide with each part of the submerged abalone cage, Oxygen can be increased.

A multifunctional layer 400 is formed below the current communication layer 300. The multifunctional layer 400 is surrounded by the mesh portion 120 at its upper, lower and side surfaces. Inside the multifunctional layer 400, gravel, rocks, concrete blocks, etc. are provided to provide stability to the submarine It can also fill. The multifunctional layer 400 having the weight is positioned at the bottom of the submerged abalone aquaculture device as a whole, so that the cermicultural device can be overturned or stuck on the undersea surface without being influenced by currents and can be stably maintained. It can also function as a reptile by filling gravel, rock, and concrete blocks.

In case of offshore, the risk of movement or overturning of the cage device due to strong winds or typhoons is high due to the blue. Therefore, even if the cage aquaculture device is formed by sinking type except netting, The submerged underwater cage aquaculture system to be located is also vulnerable to the effects of typhoons.

On the other hand, in the case of the sinking cage of the present invention, the influence of the typhoon and the like is less than that of the auxiliary cage, but there is a possibility of rollover due to the direction and intensity of the current. In the case of the submerged abalone cage aquaculture system of the present invention, the multifunctional layer 400 is added so that the center of gravity of the cage is directed downward, so that the aquaculture device can be kept more stable on the sea floor.

The multifunctional layer 400 may be formed by stacking a hardened frame with concrete in addition to filling the meshes 120 with rocks or the like capable of giving weight, , The remaining multi-function layer (400) can be used for other aquaculture types.

FIG. 2 is a perspective view of a culture aquaculture unit 700 constituting a sinking abalone cage according to the present invention, and FIG. 3 shows a plurality of aquaculture zone units 700 connected to form the sinking abdominal cage of the present invention Fig.

The supporting part 500 formed under the abalignment type layer 100, the sea cucumber cultivation layer 200, the current communication layer 300, the multifunctional layer 400 and the multifunctional layer 400 is connected to the side mesh part 120 And a plurality of aquaculture zone units 700 are connected to the sides continuously to form a polygonal column or a circular sinking abalone cage that forms a through hole 600 at the center .

In one embodiment of the present invention, an octagonal shape was made considering the preparation and usability. The connected aquaculture zone unit 700 shares the adjacent frame 110 with the netting portion 120 on the side and the aquacultural portion 120 is divided by the side netting portion 120 so that aquaculture such as abalone is generally placed on one side of the cage , And it allows the whole of the aquaculture to access to the food when the food is administered.

The frame 110 may be divided into a vertical frame and a horizontal frame, and a horizontal frame may be divided into a letter shape steel or the like. The vertical frame is formed in a pipe-like shape having upper and lower openings connected to the support portion. By opening the upper and lower parts of the pipe, the lower part of the support can be firmly fixed to the sand or mud with only its own load, and when lifting the aquaculture device, It removes the difficult phenomenon and easily discharges the subsoil sediment remaining in the support part of the poor quality and the dropped pipe to the lower hole. Accordingly, it is preferable to form one or more through holes so as to eliminate the vacuum in the pipe on the side of the pipe of the vertical frame or on the side of the support, considering the development of the vacuum phenomenon caused by the bottom portion and the support.

In addition, the cage through-hole 600 formed at the center of the submerged abalone cage not only allows the clear sea water to communicate with the aquaculture zone by the free movement of the ocean current along with the current communication layer 300, The current energy can be dispersed from the side or bottom to the side or top to prevent the submerged abalone cradle from overturning or being swept into currents.

4 is a perspective view showing the lower part of the submerged abalone cage aquaculture apparatus according to the present invention. Below the multifunctional layer 400 is formed a support 600 that can extend from the frame 110 or be formed independently to support the submerged abalone aquaculture device. The supporting part 500 is formed as a plurality of legs so that the sinking type abalone cage can be seated on the seabed surface while being spaced apart from each other by a predetermined space. By separating from the seafloor, it is possible to prevent the deforestation of aquatic organisms by pirate creatures from the sea floor, and to prevent pollutants that may be present on the sea floor from rising into the aquaculture area as the sand or pearl of the sea floor flows .

The supporting part 500 has a leg hole 510 formed at the center of the supporting part 500. When the bottom surface of the supporting part 500 is made of pearl or sand, The pearl or sand can penetrate to extend the ground plane of the submerged abalone cage and increase the frictional force, preventing the cage from being swept by currents. It can also be easily removed from the ocean floor when lifting the submerged abalone cage to sea level.

When the seabed surface is made of pearl or sand, the supporting part 500 is further embedded in the seabed surface. At this time, the multi-functional layer 400 having a weight of stone or the like is provided in the flat space formed on the support part 500 , And aquaculture area located above the multifunctional layer (400) can be prevented from being touched or buried on the seabed surface even when the sea floor is soft and pale. In addition, even when the support portion 500 is buried in the undersurface of poor quality and the lower portion of the cage through hole 600 is blocked by the sea floor, communication of the currents is facilitated by the current communication layer 300 and the upper cage hole 600 It is possible to maintain a good aquaculture environment.

A rope connecting portion (not shown) is formed at one side of the frame 110 to easily sink into the sea or pull it up to sea, and the rope is connected to the rope connecting portion to be moved in the sea, sea, or land.
