Sea cucumber, an echinoderm, belongs to the genus of pure tree, dolgi sea cucumber and dolgi sea cucumber. About 1,500 species are known worldwide, and about 14 species are known to live in Korea, and there are two species that are useful industrially. There are various types of sea cucumber, and the difference in size and grade is relatively large. High-grade sea cucumbers mainly refer to stone sea cucumbers originating from Japan's Kwandong, Russia, Liaoning Peninsula, Shandong Peninsula, and the Korean peninsula, and intermediate sea cucumbers include South American sea cucumbers, plum blossom sea cucumbers, and ivory sea cucumbers. And topaz sea cucumber.

The shape of the sea cucumber has a long cylindrical shape in the front and back, and there are several hump-shaped projections on the back. The mouth is open at the front end of the body, and there are several tentacles around it, and the anus is at the rear end. Also, most species have a lot of crown feet made of thin tubes on the bottom, and they crawl under the sea with this. Species without crown feet float in the sea or live in sandy mud. There are sparsely calcareous small bone fragments in the skin. Most of them are male and female, but it is difficult to distinguish them from their appearance.

Sea cucumber is an alkaline food that is rare among animal foods. It has been said to have the same medicinal effect as ginseng since ancient times. In addition to boyangseong, sea cucumbers live in clean places affected by the open sea water, so they are clean, and they are eco-friendly by feeding natural algae, and can be processed into various types of products when mass-produced.

Sea cucumber is attracting attention as a new species for culture in Asia, mainly in China. In Korea, sea cucumber has been designated as one of the eight national favorite seafood products by the Ministry of Food, Agriculture, Forestry and Fisheries, as well as a variety of research and development projects by designating it as one of the top 10 strategic aquaculture varieties.

Sea cucumber repeats a fixed life every year according to changes in water temperature or season. Around 8~16℃, the appetite is active and the exercise is active, so the growth rate is high. At 17~19℃, exercise is not active and appetite decreases, and the digestive tract atrophy, and if it is over 25℃, it enters the fasting state and does the lowering (夏眠). The actual growth period varies depending on the sea area, but usually from December to April of the following year, sea cucumbers before and after the winter solstice taste the best.

In nature, the habitat of sea cucumbers is sand, rocks, etc. However, it cannot inhabit in tidal flats without a substrate, and its density is low in piles of stones. The diet is omnivorous and prefers seaweed, but grows even in areas where seaweed is scarce by feeding on organic matter and diatoms present in the seabed. In addition, when you smell the rot of mussels, it has a tendency to flock. When eating, use the tentacles around the mouth to put mud or sand under the sea into the mouth to feed in organic sediments such as seaweed, and to send out sand and excrement. When it is stimulated from the outside, the intestine is cut off and sent out of the anus, which is regenerated because of its strong regenerative power.

In 1990, the National Institute of Fisheries Science succeeded in the production of artificial sea cucumber seedlings for the first time in Korea, and since 2006, the development of technology for the industrialization of seedling, festival and land aquaculture has been promoted. Sea cucumber farming is mainly done in October or November, three months before the natural spawning season, by preparing mothers for seed production and completely discharging the excrement for 3 to 4 days, and then spawning and embedding by methods such as extraction stimulation, water temperature stimulation, and surface stimulation. And the fertilized eggs are transferred to an incubator to hatch and grow.

The water temperature during the larval period is maintained at 22~24℃ and is fed as food for phytoplankton or concentrated products. Sea cucumbers go through the larvae of auricularia, doriolaria, and pentactula, grow by planting them on the papilla in the larval stage of pentactula, and after several months into 1 cm young sea cucumbers. Grow.

In recent years, due to the deepening of marine pollution, onshore sea cucumber farms are increasing. A conventional onshore sea cucumber farm accommodates breeding water inside, a tank into which feed for sea cucumber aquaculture is input, an attachment installed at regular horizontal and vertical intervals from the bottom of the tank, and an inlet and drain to supply the breeding water into the tank.

A typical land sea cucumber farm has a tank for receiving breeding water and feeding feed for sea cucumber farming, an attachment installed at a horizontal and vertical interval from the bottom of the tank, and an inlet and a drain for supplying the breeding water into the tank. It consists of a configuration that is installed, and at this time, a net may be introduced as an attachment. However, the net is installed perpendicular to the bottom, and when food is supplied through the upper opening of the tank, the fed food falls to the bottom and sea cucumbers are distributed only at the bottom with the food, not evenly distributed throughout the tank. There is a problem that the growth rate is low. Accordingly, an object of the present invention is to provide a sea cucumber farm for land that can be collected in an attachment device for feeding feed, and is formed in a structure that considers the characteristics of sea cucumber as much as possible to increase the growth rate due to stress reduction.

Hereinafter, a detailed description of the accompanying drawings related to the land sea cucumber farm of the present invention will be described.

1 shows a plan view of a sea cucumber farm for land use of the present invention. The land sea cucumber farm of the present invention surrounds the polygonal tank bottom and the edge of the tank bottom by an outer wall of the tank having a predetermined height, and forms an inner space in which breeding water and sea cucumber attachment devices can be installed; At least one sea cucumber attachment device 300 is installed in the inner space of the aquaculture tank perpendicular to the bottom of the tank; A support rope 200 installed in one or more openings of the aquaculture tank in the installation direction and the longitudinal direction of the sea cucumber attachment device installed in the plurality may be connected and fixed to the top of the sea cucumber attachment device.

The support rope 200 according to the present invention has a core portion including one or more strands formed of natural or synthetic fiber yarns, and a structure surrounding the core portion and covered with a coating layer. Both ends of the support rope are fixed to the upper opening of the aquarium through fixing devices such as bolts and nuts. In addition, the support rope is fixed in connection with one or more sea cucumber attachment devices so that the sea cucumber attachment device can be stably fixed in the space inside the tank. The core of the support rope may be formed of natural fiber yarn or synthetic fiber yarn. In this embodiment, the deep structure is a structure formed by twisting one or more strands twisted in one direction of a plurality of single yarns in the other direction. In addition to that, it is possible to use a single-ply deep section in which a number of single yarns are twisted in one direction.

The natural fiber yarn or synthetic fiber yarn, for example, in the case of synthetic fiber yarn, polypropylene (polyproptlene), polyester (polyester), nylon (nylon), vinylon (Vinylon), vectran (vectran), aramid (Aaramid), polyester span ( polyester spun), ultra-high molecular weight polyethylene, biodegradable yarn, etc., and natural fiber yarn can be carbon fiber, hemp, cotton, etc.

The coating layer is made of polyethylene resin, near-infrared absorbing dye, ultraviolet absorber, and antioxidant to prevent abrasion of the support rope and play a waterproof/antifouling role, thereby reducing the frequency of replacement work due to damage to the rope.

In addition, seaweed seedlings that can be food for sea cucumbers are transplanted to the support rope, and the amount of sea cucumber food in the aquaculture tank can be supplied by additionally winding or fixing the germinated and grown transplant rope.

Figure 2 shows a front view of the sea cucumber attachment device of the present invention. In the sea cucumber attachment device 300 of the present invention, an attachment net 202 provided with a habitat for feeding activities by attaching sea cucumbers is installed so as to be perpendicular to the bottom of the aquaculture tank, and at least one buoyancy device 201 on the top of the attachment net Is installed, and a plurality of sedimentation devices 203 may be installed under the attachment substrate.

The buoyancy device 201 is formed in the form of a buoyancy material applied to a conventional fishing gear and may be formed of a material such as wood, glass, metal, synthetic resin, or the like. The sedimentation device 203 may be formed of a sinker, a weight, or the like in a structure of a sedimentation material installed in a conventional fishing gear.

The buoyancy device and sedimentation device should be installed above and below the attachment substrate to have the buoyancy and sedimentation force that the attachment substrate can develop in the water, and the arrangement and number of the buoyancy device and the sedimentation device are It can be adjusted so that the attachment net can be extended and deployed in the up, down, left, and right directions underwater.

Figure 3 shows a side view of the attachment net of the present invention. The attachment net 202 of the present invention is preferably made of a synthetic fiber yarn material such as nylon, polyethylene, polypropylene, polyester, etc., so that surface friction and the nodes of the mesh that are not released continuously cross the net threads to each other. In other words, it may be a seamless network or a rassell network. The raschel net is also referred to as a russell net or a rassell net, and the nodule net is implemented in a knotless form, and may include a straight net, a female net, and an adhesive net.

In sea cucumber farms, microalgae are generated to feed the sea cucumbers to shelters and attachment nets, but the attachment net of the present invention is preferably formed in blue color. The blue color is intended to promote the growth of microalgae so that the amount of adherent microalgae can be increased.

As shown in Fig. 3, even if the attachment net is deployed up and down by the buoyancy device and the sedimentation device and installed vertically with the bottom, the tensile force is stronger than other nets, so that the nodes of the mesh formed by crossing each other are in one direction. A curvature in the form of a curved bone structure is formed. Therefore, not only the food supplied through the upper opening can be seated in the combined frame of the bone structure, but also a space in which sea cucumbers can hide can be formed.

Typically, the sea cucumber seltzer network installed in the land tank is formed perpendicular to the bottom of the tank. In such a structure, sea cucumbers move in the vertical direction in the shelter net, but the vertical attachment is unnatural for sea cucumbers than the horizontal attachment. In addition, as the food fed to the top sinks into the bottom of the tank, the sea cucumbers come down to the bottom and feed feeding is required.Therefore, the amount of activity increases and the amount of individuals distributed almost at the bottom increases the stress, which may cause the sea cucumbers to contract. .

4 shows a side view of an attachment net according to an embodiment of the present invention. The attachment net according to the embodiment has a structure in which a plurality of protrusions 202a are formed on the side of the attachment net made of the same net material of a nodule net and a rassell net. The protrusion is obtained by attaching and joining the mesh of a raschel net or a nodule net by cutting the net horizontally and vertically so as to have a certain length and area to the net and the net of the attachment net. The cut net piece is rolled in one direction due to the nodular nature of the nodular net and the raschel net, so it is attached to the attachment net and is maintained in a pocket shape forming a circular space in cross section to increase the attachment area of the sea cucumber by increasing the surface area of the side. The upper side of the protrusion is attached to sea cucumber food such as microalgae and sea cucumber feed, so that the amount of food biomass in the land tank can be increased, and the lower side made of a pocket acts as a blocking film to avoid sunlight to become a hiding space for sea cucumbers. I can. The embodiment considers the characteristics of sea cucumber as much as possible, and the stress of sea cucumber can be reduced and the growth rate of sea cucumber can be increased with abundant food.

5 shows a side view of an attachment net according to another embodiment 2 of the present invention. The attachment net according to Example 2 is a structure in which a plurality of hiding structures 202b having a ring shape in cross section are formed in the same network structure as the attachment net on the side of the attachment net. The concealment structure is obtained by attaching a net piece cut into a length of 4 to 10 noses in length according to the number of meshes to have a certain area of a raschel net or a nodule net.

Since the cut net piece is rolled in one direction due to the nature of the nodule net and the rassell net, it is attached to the attachment net, thereby increasing the surface area of the side portion and increasing the attachment area of the sea cucumber. On the other hand, since sea cucumber food such as microalgae and sea cucumber feed is attached to the upper side of the protrusion, the amount of food biomass in the land tank can be increased, and a moving passage for the movement of sea cucumber is formed in the lower part, so that the sea cucumber is used as an internal hiding space. Damage can be moved. In addition, as the same effect as the protrusion, the surface area increases, thereby increasing the adhesion area and the amount of food organisms attached.

6 shows a land sea cucumber farm according to Example 3 of the present invention. In the land sea cucumber farm according to Example 3, an upper opening is formed in a form surrounding a polygonal tank bottom and an outer wall of the tank having a predetermined height, and a tank body having an inner space portion in which breeding water and sea cucumber attachment devices are stocked, and the An aquaculture tank that divides the left and right internal spaces by installing a central partition wall formed in the center of the inner space to a length shorter than the length of the tank body; At least one sea cucumber attachment device is installed in the inner space of the aquaculture tank perpendicular to the bottom of the tank; A support rope may be connected to and fixed to the top of the sea cucumber attachment device at the top of the aquaculture tank opening and the central partition wall in the installation direction and the longitudinal direction of the sea cucumber attachment device installed in plurality.

The aquaculture tank formed according to Example 3 is a type that is installed in a large aquaculture, and as the area of the land tank increases, the number of injectors and water pressure that are installed for water flow must be increased. Can increase. Accordingly, it is formed as a track-type water tank that installs the central partition wall in the culture tank, so that smooth water flow in the tank can be formed without increasing the number of injectors and water pressure.

In the present invention, food can be settled in the attachment period and food organisms such as microalgae can be produced, so that sea cucumbers can be distributed in a balanced land tank, as well as high growth in a short time by providing abundant food, increasing the profits of related businesses. As a result, it has industrial applicability.
