Description

Festival type sea cucumber seedling production equipment and sea cucumber culture method {APPARATUS FOR REARING SEA CUCUMBER AND METHOD FOR REARING SEA CUCUMBER HAVING THE SAME}

The present invention relates to a festival type sea cucumber farming apparatus, and more particularly, to a farming device which is used in a festival type sea cucumber farm, so that the larvae of sea cucumbers living in a floating life can easily enter the attachment life.

Recently, the demand for seafood such as sea cucumbers has been greatly increased, and the income of fishermen has been greatly increased. Interest in health and wellness has been increasing in the echinoderm, the echinoderm, and in the eastern regions such as Korea and China, sea cucumber is the best stamina food And popularity is increasing day by day. Especially, sea cucumbers are the fish products preferred by Chinese people.

The major amino acid components of sea cucumber protein are arginine, cystine, histidine, and lysine, and taurine, which is a bile component, prevents anemia and facilitates the exercise of the liver. In particular, calcium and tannins prevent cancer and stomach ulcers, promote appetite, promote metabolism, and reduce calories, which are effective in preventing obesity, and are also useful as health foods such as high blood pressure, arteriosclerosis, diabetes patients, and obesity. In addition, sea cucumber contains 0.4mg / 100g of vanadium and occupies the first place among various foods. The physiological efficacy of vanadium transports iron in the liver to the liver so that iron is sufficiently absorbed to form hemoglobin. (acidicmucopolysaccharide) has a special active substance such as fucosylated chondroitin sulfate (Fucosylatedchondroitin sulfate). Fucosylated chondroitin sulfate prevents the aging of the human body, acid mucopolysaccharide has anticancer action, prevents acute radioactive damage, and promotes recovery of hematopoietic function. Therefore, sea cucumber has antitumor, anti-aging, anticoagulant, anti-radiation, white blood cells to enhance the phagocytosis, and enhance the body's immunity.

The spawning season of sea cucumbers differs depending on the east coast, west coast, and south coast. The sea cucumbers start from the south coast where the water temperature rises first, and then the west coast and the east coast. Normally females spawn between 3 and 5 million eggs, and large individuals with a body size of more than 500 g spawn amounts to 10 million eggs.

The spawning of sea cucumber is about 3 ~ 5 ℃ higher than natural water temperature, so it is possible to settle and breed eggs. The eggs of the sea cucumber begin to divide when fertilized, and then hatch after about 24 hours. Then, as time goes by, they become wealthy while undergoing metamorphic processes such as Auricularia, Dolly Orario, and Pentaktura. The larvae, who lived in a floating life, soon came to the tentacles and attached to the substrate to feed.

It takes about 10 to 12 days for the Pentectura to be fertilized with sea cucumber eggs. About 48 hours after fertilization, stomach is formed. From this time, food should be fed. Larvae feed on chaetoceros calcitrams, isochrysisgalbama and pavlora lutheri.

The mature egg of the sea cucumber has a diameter of 150 ~ 170μm and it is a sedimentary egg that sinks in water. About 48 hours after incubation, it transforms into early auricularia and its size is 360 ~ 430μm. After 5 days, it grows to mid-auculularia and its size is around 700μm. After 7-8 days, it grows to late auricularia and its size grows to around 1000μm. In about nine days, the metamorphosis to Dolly Orario, the size of which is rapidly reduced to less than half, 400-500μm, the body becomes rigid and translucent to translucent. After about 10 days, it moves from the larvae's rich life to the attachment life as it proceeds to Pentec Tura, where the tentacles are produced.

Pentacura is called the tentacle fluid because five tentacles are pushed out of the body. The tentacle extends from the body and gradually branches laterally. The larvae that are attached at the time of attachment are attached to the substrate (where sea cucumbers attach and feed). Seedlings are seeded when about 20% of all larvae occur. The method of seeding is to put the attached substrate into the larval breeding tank for harvesting and to capture the larvae using the siphon or the larval gathering net in the larval breeding tank, and larvae are sprayed by spraying the larvae on the tank prepared with the attached substrate in advance. In some cases, the rate of seedlings is increased by drawing when the transformation of Dollario is more than 50%.

Healthy larvae should not be delayed for harvesting, as the transformation rate of Dolliolario may reach more than 50% three or four hours after the discovery of the first Dolloario in Auri Clario. Dollyorario still swims in the water, but sits on the ground and tries to adapt to life. However, when time is delayed and the seeding is delayed, the larvae are not evenly seeded on the attachment substrate but sink to the bottom or are concentrated only on a part of the attachment substrates placed on the farm.

In the farm, sea cucumbers are attached evenly at regular intervals, and the foods of sea cucumbers administered to the farm are evenly distributed. Therefore, it is very important for the culture of sea cucumber that the sea cucumber, which had been in affluent life, is evenly attached to this attachment substrate. In addition, since the sea cucumber larvae do not develop tentacles at the initial stage of the tentacles, it is not easy to attach them to the attachment substrate by their own force, and thus a device for helping the sea cucumbers are easily attached.

In addition, after the sea cucumber grows and the adhesion force is sufficient, it was necessary to easily change the shape of the adhesion substrate in consideration of other conditions for aquaculture, such as the discharge of excretion of the sea cucumber, not easy attachment.

In addition, young sea cucumbers whose larvae have just entered the life of attachment have very soft skin. If copepods are present in the farm, the sea cucumbers are severely damaged by their sharp shells or feet. There is a problem of being harmed. Therefore, a means was needed to prevent the large breeding of copepods in sea cucumber farms.

The present invention provides a farming apparatus having a structure that can be easily attached to the sea cucumber larvae not enough adhesion in the step of entering the life of larvae from the floating life to the attachment life,

In addition, it is an object of the present invention to provide a farming apparatus that allows the attached sea cucumber larvae to be changed into a form that can easily release the excrement of the sea cucumber for feeding after the adhesion is sufficient.

It is also an object of the present invention to provide a means for combating copepods that interfere with the habitat of sea cucumber larvae during their attachment and feeding activities.

The present invention, the support member 10 is fixed to the bottom of the farm at an angle or vertically; An upper plate 20 and a lower plate 30 rotatably provided at upper and lower sides of the support member 10; A plurality of attachment substrates 40 disposed between the upper plate and the lower plate, one end of which is fixed to the support member 10; First connecting means (50) connecting the upper plate and the lower plate and the attachment substrate to each other so as to maintain a predetermined distance; It provides a festive sea cucumber seedling cultured device comprising a; the second connecting means 60 for connecting one end of the upper plate 20 and the upper end of the support member 10 to each other.

The upper plate 20 and the lower plate 30 and the attachment substrate 40 are arranged parallel to the water surface, the upper plate and the lower plate is made of a hard material of any one of plastic, wood, metal, the attachment It is preferable that the substrate is made of a plastic or a flexible material of vinyl or a light shielding film.

At least one supporting member is disposed to support the upper plate 20, the lower plate 30, and the attachment substrate 40. When the second connecting means 60 is disconnected, the upper plate 20 and the lower plate are supported. The plate 30 and the attachment substrate 40 are vertically arranged by gravity, and the support member may be fixed by a fixing member embedded in the bottom of the farm.

In addition, the present invention comprises the steps of installing the festive sea cucumber seedling cultured device described above in the festive farm; And the step of eliminating copepods by inserting the fish from the fishery to the festive fish farm, jeombokrak, black sea bream. Any one or more of, byeongmubang, slippery, rice cakes, Jeju rice cakes, yellow wires, small nets can be used.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

The present invention relates to a sea cucumber culture apparatus having an attachment substrate that can be easily attached to the larvae of floating sea cucumbers disposed inside the festive sea cucumber farm.

1 is a view of a part of the configuration of the festival sea cucumber culture apparatus according to an embodiment of the present invention, Figure 2 is a view showing the overall appearance of the sea cucumber culture apparatus, Figures 3 to 4 are installed obliquely in the festival farm Side view of the sea cucumber culture apparatus of the present invention.

1 to 3, the sea cucumber culture apparatus used in the festival farm according to the present invention, one or two support members 10 are fixed to the bottom of the festival farm. The support member 10 may be made of a wooden rod or a plastic rod or an iron rod, and the material is not particularly limited. The support member 10 is fixed to the bottom end 10a is embedded obliquely at the bottom of the farm. The lower end 10a of the support member may be directly buried in the bottom of the farm, and a separate fixing means (not shown) is embedded at an angle to the bottom of the farm in advance and the support member 10 is attached to the fixing means. It may be fixed at an angle.

The upper plate 20 and the lower plate 30 are attached to the upper and lower sides of the support member 10 so as to be rotatable by a predetermined angle from the support member. That is, the upper and lower plates are rotatably attached by a predetermined angle in the connecting portions indicated by A and B in FIG. 2, so that the angles of the surfaces of the plates with the ground can be changed as described below.

In addition, a plurality of adhesion substrates 40 are disposed between the upper plate 20 and the lower plate 30. The attachment substrate 40 is located between the upper plate and the lower plate, one end is fixed to the support member 10, the other end is attached to the first connecting means (50). The first connecting means 50 is made of a general rope or string, and connects the edges of the lower plate 30 to each other at the edge of the upper plate 20, the edge of the attachment substrate 40 in the center portion Connected. The larvae of sea cucumbers float in the water and are attached to the attachment substrate 40 to live while feeding. The plurality of attachment substrates 40 are connected to the support member 10 and the first connecting means 50, respectively, and are arranged to maintain a constant gap between the upper plate and the lower plate.

In addition, the sea cucumber culture apparatus according to the present invention includes a second connecting means 60 for connecting one end of the upper plate 20 and the upper end 10b of the support member 10 to each other. The connecting means 60 may also be any general connecting means such as a rope or a rope. And, by adjusting the length of the second connecting means it is possible to adjust the angle between the upper plate and the lower plate and the ground. The upper plate and the lower plate is made of a hard material of any one of plastic, wood, metal, it is good to withstand a certain degree of force. In addition, the adhesion substrate may be made of a flexible material or plastic of vinyl or a light shielding film.

In the sea cucumber culture apparatus according to the present invention, as shown in Figure 3, the support member 10 is fixed to the bottom in the farm, but is arranged obliquely. The upper plate 20, the lower plate 30, and the attachment substrate 40 adjust the length of the second connection member 60 to be substantially parallel to the water surface. To this end, the second connection member is easily formed to adjust the length between the upper plate and the upper end of the support member.

In this state, the larvae of sea cucumbers are introduced into the farm, but those that are in the stage where sea cucumber larvae are required to be harvested. Dollyolario, a larvae of sea cucumbers, must be harvested at the right time to swim in the water, but at the same time to adapt to the life of attachment. If the seedlings are delayed, the larvae do not evenly adhere to the adherent substrate, but sink to the bottom or attach to only a part of the adherent substrate.

By the way, the larvae of sea cucumbers are still in a weak state of adhesion and cannot easily adhere to the adhesion substrate. Thus, the attachment substrate 40 according to the present invention is disposed in parallel with the ground (water surface) so that the sea cucumber larvae with weak adhesion. Because, when the attachment substrate is disposed obliquely, because the adhesion of the sea cucumber is weak, it is not attached and slides down.

As shown in FIG. 3, when the sea cucumber larvae attached to the adherent substrate are kept flat and eat the food placed on the adherent substrate, the sea cucumber larvae have sufficient adhesion force. In this state, even if the attachment substrate is inclined, the sea cucumber can be attached to the attachment substrate by itself and live. In this state, maintaining the adhesion substrate horizontally is rather disadvantageous because the excrement of sea cucumber continues to accumulate thereon.

Therefore, when the adhesive force of the sea cucumber is in a sufficient state, the second connection member 60 is cut in FIG. 3. Then, the sea cucumber culture apparatus is rotated by the weight of the upper plate 20 and the lower plate 30 to be placed perpendicular to the ground, that is, in the vertical direction to the state shown in FIG. Although the attachment substrate is vertically placed, the sea cucumber has sufficient adhesion force so that it can be attached and continue to feed without falling from the attachment substrate. At the same time, the excretion of the sea cucumber does not accumulate on the attachment substrate and flows down from the attachment substrate to the bottom of the farm. This will eliminate the problem of sea cucumber droppings on the attachment substrate. When the second connecting member is cut, a weight (not shown) having a predetermined weight may be suspended on the lower plate to help the upper and lower plates rotate in the vertical direction.

Sea cucumber culture apparatus according to the present invention, by using the second connection member not only to easily attach sea cucumber larvae with a weak adhesion, but also a simple operation in the state of sufficient adhesion (simple to cut the second connection member made of a string Operation) to adjust the inclination angle of the attachment substrate to prevent the accumulation of feces.

Figure 5 is a side view of the festive sea cucumber culture apparatus according to another embodiment of the present invention, Figure 6 is another embodiment of the sea cucumber culture apparatus shown in FIG. The sea cucumber culture apparatus in the present embodiment is different in that the support member is configured to be perpendicular to the ground.

Referring to FIGS. 5 to 6, when the sea cucumber farming apparatus used in the festival farm according to the present invention, one or two support members 110 is fixed approximately perpendicular to the bottom of the festival farm, the support member ( 110 is fixed to the bottom end 110a is buried in the bottom of the farm. The lower end 110a of the support member may be directly fixed to the bottom of the farm, or a separate fixing means (not shown) may be fixed to the bottom of the farm in advance and attached to the support member excitation fixing means. In addition, the upper plate 120 and the lower plate 130 are attached to the upper and lower sides of the support member 110, so as to be rotatable by a predetermined angle from the support member.

In addition, a plurality of adhesion substrates 140 are disposed between the upper plate 120 and the lower plate 130. The attachment substrate 140 is located between the upper plate and the lower plate, one end is fixed to the support member 110, the other end is attached to the first connecting means 150. The first connecting means 150 is made of a general rope or string, and connects the edge of the lower plate 130 at the edge of the upper plate 120, the edge of the attachment substrate 140 in the center portion Connected. The larvae of sea cucumbers are floating in water and are attached to the attachment substrate 140 to live while feeding. The plurality of attachment substrates 140 are connected to the support member 110 and the first connection means 150, respectively, and are arranged to maintain a constant gap between the upper plate and the lower plate. And, it includes a second connecting means 160 for connecting one end of the upper plate 120 and the upper end (110b) of the support member 110 to each other. The connecting means 160 may also be any general connecting means such as a rope or a rope. And, by adjusting the length of the second connecting means it is possible to adjust the angle between the upper plate and the lower plate and the ground. The upper plate and the lower plate is made of a hard material of any one of plastic, wood, metal, it is good to withstand a certain degree of force. In addition, the adhesion substrate may be made of a flexible material or plastic of vinyl or a light shielding film. In addition, in the sea cucumber culture apparatus according to the present embodiment, the protrusions 200 may be provided at the ends of the upper plate 120, the lower plate 130, and the attachment substrate 140. The role of the protrusions serves to prevent the adhesion substrates from overlapping each other in FIG. 6, which will be described below.

In the sea cucumber culture apparatus according to the present embodiment, as shown in Figure 5, the support member 110 is fixed to the bottom of the farm, but is disposed approximately vertically. In addition, the upper plate 120, the lower plate 130, and the attachment substrate 140 adjust the length of the second connection member 160 to be substantially parallel to the water surface. To this end, the second connection member is easily formed to adjust the length between the upper plate and the upper end of the support member.

In this state, when sea cucumber larvae are in the stage of needing seeding, they are attached to a flat attachment substrate and grow for a certain time. When the sea cucumber grows and the adhesive force is sufficient, even if the attachment substrate is inclined, the sea cucumber is attached to the attachment substrate by magnetic force, thereby cutting the second connection member 160. Then, the sea cucumber culture apparatus is rotated by the weight of the upper plate 120 and the lower plate 130 to be placed in a substantially vertical direction on the ground in the state shown in FIG.

In addition, by the protrusions 200 provided at the ends of the upper plate 120, the lower plate 130, and the attachment substrate 140, the attachment substrates may not be overlapped with each other and maintain an oblique shape close to the vertical. The attachment substrate is arranged obliquely close to the vertical, but since sea cucumbers have sufficient adhesion, they can be attached and continue to feed without falling off from the attachment substrate. At the same time, the excretion of sea cucumbers does not accumulate on the attachment substrate and flows down from the attachment substrate. Because it goes down to the bottom, it is possible to solve the problem that the excrement of sea cucumbers accumulate on the attachment substrate. When the second connecting member is cut, a weight (not shown) having a predetermined weight may be suspended on the lower plate to help the upper and lower plates rotate in the vertical direction.

In the embodiment of Figures 5 to 6 attached to the projection 200 to the end of the adhesion substrate to prevent the adhesion substrates overlap each other, in some cases, it is also possible to form a device omitting the projection. That is, in FIG. 6, it may be possible that the attachment substrates overlap with each other at an end portion, and if the attachment substrate 140 is sufficiently widened to be attached to the support member 110, the attachment substrate and the attachment substrate may be in the state of FIG. 6. It would be possible to avoid overlapping.

Sea cucumber farms need to take countermeasures because copepods breed and damage young sea cucumber larvae.

As shown in the photo of Fig. 7, copepods have hard shells and sharp feet and tails compared to young sea cucumbers, and also float underwater but crawl on attachment substrates, unlike sea cucumber farms, unlike in the natural environment of the sea. The phytoplankton, which is a food for copepods in the water, is relatively small, and the food is adsorbed on the adhering substrate.

The young sea cucumber that enters the membrane life after the larval period is very fragile. At this time, the sharp shells and feet of the copepods injure the skin of the fragile young sea cucumber larvae. Sea cucumbers are almost annihilated. In particular, the copepods behave quite fast, but the behavior of the sea cucumbers is very slow and the damage becomes even bigger. Since the sea cucumber farming system has an adherent matrix in the water and an adherent diatom (phytoplankton) is formed on the adherent substrate, the copepods gradually become more numerous as the diatoms feed on the copepods. There is a problem that causes catastrophic damage.

Therefore, countermeasures against copepods should be established during the period when the sea cucumbers grow to a certain degree and the skin is not directly affected by copepods (about 60 days).

In the present invention, in order to combat copepods, we devised a method of injecting the nettle fish or sea bass rockfish into the farm. Such copepods are advantageous as small as possible. This is because the small size of the body is enough to keep on feeding small-sized copepods.

The characteristic of smelt and fish is that it adapts to live on the floor by using a round sucker that is deformed by right and left media fins sticking together. The nettlefish live mainly on the bottom of the shallow coast because of their small body and poor swimming. Although swimming is poor, it can be comfortably attached to the rocks of the sea, the stems of algae, or the thin lines. This is a posture that can only be seen in the nettlefish and is possible because of the deformed medium fin. When these fish are put into the sea cucumber farm, they may be attached to the attached substrate or the fish reef in the farm, thereby eliminating the copepods inhabiting it. Fishes belonging to the fish family are commonly referred to as 'pike fish', such as 'pile fish' and 'big crested fish fish'. The 60 species of nettlefish that live in Korea grow up to 7 centimeters and the large species grow up to 40 centimeters. Among these, the smaller ones are zigzag, ziddham, zigzag, grass scale, squirrel, squirrel, jeju mochi, hwangju and so on. In addition, for these copepods, in addition to these nettlefish, black sea bream or fish may also be injected.
