Description

{Controlling method of the time of sea cucumber artificial seed production through management of parents sea cucumbers in land farm}

The present invention relates to a method for controlling the early production and production time of artificial seedlings of sea cucumbers through terrestrial management of mother sea cucumbers, and more specifically, selecting superior red ginseng, and controlling water temperature and managing feed to make it faster than normal natural sea cucumbers. It relates to a method for early production and control of production time through ground management of mother sea cucumber, which includes adjusting the spawning date to spawn and growing the produced fertilized egg into hatchery and ginseng.

Sea cucumber is a class of Phylum Echinodermate, which is a marine organism belonging to the class Holothuroidea, and was named sea cucumber because it has the same efficacy as ginseng. In the old documents such as Jasanbobo, it is recorded as sea cucumber, native meat, man, black beetle, etc. In Japan, it is called a namako, which means sea rat because it is nocturnal and resembles a mouse.

The body has a long cylindrical shape back and forth, and there are several bumps on the back. The mouth is open at the front end of the body, with several tentacles around it, and an anus at the rear end. In addition, most species have a large set of coffins on the bottom, which crawl under the sea. Species that do not have a spectator float in the sea or are buried in sandy mud. In the skin there are sparsely small, calcareous bone fragments. Most of the sexes are distinguished, but it is difficult to distinguish them by appearance.

Sea cucumbers repeat their lives every year according to changes in water temperature or season. The appetite is vigorous and active at around 8~16℃, the movement is not active at 17~19℃, the appetite decreases, the digestive tract contracts, and when it reaches 25℃, it goes into a fasting state and sleeps in summer. sleep. When feeding, the mud or sand under the sea is put in the mouth with tentacles around the mouth to feed organic sediments, such as seaweed, and the sand and excrement are sent out. When stimulated from the outside, the intestine is cut off and sent out of the anus.

Since sea cucumber is rich in vitamins and minerals, it relieves fatigue and excites energy, restores the functioning of the body with no appetite or exhausts, and smoothes metabolism, thereby refreshing children, the elderly, and pregnant women. It is known to have a healing effect. In addition, a component called holotein destroys bacteria and prevents clotting of blood, so it has an anti-cancer effect, and fatty acids contained in sea cucumber are effective in asthma, colorectal cancer, and arthritis. In addition to this, sea cucumber purifies the blood and is considered as the best tonic because it is good for enhancing male sexual function.

Korea became the first in Korea to produce artificial seedlings of sea cucumber in the National Fisheries Research and Development Institute in 1990, and sea cucumber farming became active.Since 2006, the development of seeding, festival and land tank farming industrialization technology has been promoted.

Conventional production of artificial seedlings of sea cucumbers consists of a method of inducing spawning and fertilization through spawning stimulation of natural harvested sea cucumbers and obtaining seedlings by obtaining fertilized eggs. The production period of artificial seedlings is from the end of May, which corresponds to the spawning period of natural sea cucumbers. It was limited to July. In addition, it was difficult to develop superior seedlings based on this by selectively securing good traits while harvesting and using natural ginseng necessary for artificial seedling production each year.

Accordingly, Korean Patent Publication No. 10-2012-0063618 discloses a method of inducing red sea ginseng spawning, but the present invention induces premature spawning by managing the breeding temperature of the ginseng and generates the fertilized egg obtained in the tank to dig into a specific growth period. It shows a difference in its composition and effect from the early seedling production method of the sea cucumber of the present invention to increase the growth rate by moving it to a special mango.

In the present invention, by separating high-quality seedlings, increasing the initial production period by increasing the production time of artificial seedlings of sea cucumbers, and changing the necessary aquaculture device according to the growth of wild cucumbers, sea cucumbers are selected and managed for the production of artificial seedlings and through management of hemorrhoids. Provides a method for early production and control of production time through ground management of mother sea cucumber, which enables early production of artificial seedlings in early March until natural spawning.

In the Republic of Korea Patent Publication No. 10-2012-0063618, the first step of draining the seawater in the tank containing the red sea ginseng, the second step of drying the red sea ginseng upside down during the first predetermined time, heated seawater 3℃ higher than the natural water temperature Disclosed is a third step of stimulating red sea ginseng in a water tank and a fourth step of blocking light irradiated to red sea ginseng for a second predetermined time.

Since the conventional seedlings for the production of artificial seedlings of sea cucumbers were supplied only by natural harvesting in accordance with the production time of the seedlings, the production time of artificial seedlings of sea cucumbers has been limited from late May to July, and accordingly, the culture period of sea cucumbers is about 36 months. Reached. In order to solve this, the present invention is to provide a method for early production and control of production time through ground management of mother sea cucumber through the management and spawning of sea cucumber for artificial seedling production.

In order to achieve the above object, the method for early production and control of production time through the management of the mother sea cucumber according to an embodiment of the present invention is artificial seedling production using the ginseng, which is managed for many years while supplying feed from the land tank, the low temperature management period Lowering the breeding water temperature of the natural water temperature to 16.5°C for 4 weeks (A); Lowering to 10.3° C. for 4 weeks from step (A) (B); Step (C) lowering from step (B) to 8° C. for 4 weeks; and raising the temperature to breeding water temperature to 18° C. until spawning induces by raising 0.5° C. every week from step (C) to 9.5° C. for 3 weeks (D). ); Step (E) of raising the temperature from 1D to 1.0C to 18C each week for 8 weeks from step (D); The step (F) of maintaining at 18° C. from the step (E) to scattering induction; may be performed as step (A).

1. Conventional method

The mother sea cucumber for artificial seedlings is collected and supplied from nature before seedling production, and after 3 to 4 days, the feces are completely discharged, followed by spawning, water temperature, and surface stimulation. And fertilized eggs are transferred to the hatching tank to incubate and grow.

The fertilized eggs hatch and go through the larval period. At this time, the water temperature maintains 22~24℃, and it feeds on food of phytoplankton or concentrated products. The sea cucumber goes through the larval stages of auriicularia, doriolaria, and pentactula, and grows by grafting to phantom during the pentactula larval stage, and after a few months, it grows into 1 cm of young sea cucumber. Will grow.

In the conventional production of artificial seedlings of sea cucumbers, natural harvested sea cucumbers are used as the seedlings, and the seedlings grown by natural harvesting are spawning stimulations, and they spawn and spawn all at once regardless of maturity of eggs and sperm in the gonads. Therefore, the fertilization rate is not high compared to the amount of scattering. In addition, the spawning spontaneously collected is a single spawning, and since the spawning is completed, the number of fertilized eggs that can be obtained per individual is limited.

Induction of spawning and fertilization through spawning stimulation within 1 to 7 days after planting with conventionally harvested moss, and the spawning and fertility of the seedlings are discarded, the next year for the production of artificial seedlings. Inevitably, the production period of seedlings is limited from late May to July when the sea cucumbers spawn and grow in nature. Therefore, in aquaculture farms, if the seedlings are stocked and farmed at this time, there is a problem in that the survival rate decreases as much as there are three lower surface periods until shipment.

The present invention increases the initial aquaculture period by accelerating the production time of artificial seedlings of sea cucumbers, and changing the required farming method according to the growth of chissam. We established an early production method of sea cucumber that can be produced early through the month.

2. Screening of ginseng

The seedlings managed for the production of artificial seedlings are collected and secured from nature for the first time. In general, sea cucumbers are naturally hatched from late May to July, so the sea cucumbers used as the mother ginseng are collected by the haenyeo between March and June earlier than this. Mossam selected in the present invention was purchased and used naturally harvested sea cucumbers from Baengnyeong-do, Rodo, and Chungnam-do.

2.1 Screening by appearance

1 is a photograph showing the appearance of sea cucumbers to be used as moss. Among the sea cucumbers collected from natural sea water, the surface is smooth, there are no scratches, the protrusions are large and neatly arranged, the color is clear, and the weight is selected to be 150 g or more per individual.

2.2 Screening by feeding activities

Naturally harvested ginseng was fasted for a week after standing in the tank. During this fasting period, the feed is stopped and the sea cucumber is emptied using filtered seawater to empty the intestines. Thereafter, the compound feed was fed. At this time, the feed amount was 3% of the weight of sea cucumber.

2.3 Selection by feed

Conventional sea cucumber feed is a form in which sea cucumber crawls and feeds as it is layered under the tank when pearl is mixed with powdered feed and sprayed on the tank, so it is difficult to check the amount of feed per individual sea cucumber and it is difficult to measure the activity of moving for feeding. . In the screening step of the present invention and the method for early seedling production of sea cucumber, an intercepted solid feed that can grasp the degree of feeding activity during feeding and can use the degree of feeding activity for screening of the whole ginseng is used. When the feed is fed to the bottom of the center of the tank by administering a flat-type solid feed to the center of the tank, sea cucumbers on the floor or wall are collected as feed for feeding. Only high individuals can be selected.

In addition, since the sectioned solid feed does not easily dissolve in the feedstock, one individual can climb up and feed the section of the feed, and since it is easy to understand the amount of feed of each individual, the amount of feed and continuous observation of the sectioned solid feed is easy. Through this, high-quality ginseng with high feeding activity is selected.

3. Controlling the timing of artificial seedling production through land management of ginseng

Conventionally, the naturally harvested moss has a problem that there is no preservation property, such as larvae and death. Therefore, 150 g or more was used because the individual weight of sea cucumber used as the ginseng is only sufficient for natural harvesting. However, sea cucumbers, which have been managed for many years, have an individual weight of 250 to 400 g, which increases the amount of spawning and increases the efficiency of eggs.

The sea cucumber selected after natural harvesting is used as a seedling for artificial seedling production of sea cucumber through management of water temperature, feed, water quality, etc. throughout the year, and can be used as a seedling after repeated harvesting through the management of the seedling. The most important of these is the management of water temperature.

Sea cucumbers spawn and spawn once naturally from early May to July, and after summer, if the water temperature increases, you can spend the winter and then spawn and spawn again the following year. The technical feature of the present invention is to quickly restore the spawning ability of sea cucumber and control the period of time through constant water temperature change while managing the water temperature corresponding to the natural environment of the seasonal water temperature change.

3.1 Low temperature period management

Figure 2 is a graph showing the water temperature management until the next year spawning after harvesting or spawning of ginseng in the method of early seedling production of sea cucumber of the present invention. Breeding water temperature of sea cucumbers from A to C was shown in chronological order. It is managed to correspond to natural water temperature from June 1 to December 5 shown in blue. During this period, since sea cucumbers are exposed to low-temperature environments as the water temperature gradually decreases from summer, the breeding water temperature is slowly lowered to create an environment that passes through winter after the spawning. The filtered and sterilized breeding seawater is adjusted to have an appropriate dissolved oxygen, pH, and salinity, and heated and cooled to an appropriate temperature through a heater and supplied.

At this time, the breeding water temperature is lowered to 16.5°C for 4 weeks at natural water temperature (1), lowering to 10.3°C for 4 weeks from step (1), and lowering to 8°C for 4 weeks from (2) step (3) ) To reduce the water temperature by 8℃ step by step. In the general winter sea cucumber farming, it is possible to maintain 20-25°C as normal seawater or place it at a lower water temperature in the natural environment.However, if the temperature is raised from 8°C to spawning induction through preliminary experiments of the present invention, it is sufficient for the maturation of sea cucumber gonads. Confirmed.

Figure 3 shows the automatic temperature control equipment required for water temperature management of all ginseng. The above breeding water temperature is for accelerating the spawning cycle of the ginseng than the natural state, and it is important to increase the exact water temperature because it includes a process of heating the water temperature despite seasonal changes in the natural state. Therefore, it is necessary to precisely control the water temperature by adopting an automatic temperature control facility, and decrease or increase a certain temperature within a certain period.

3.2 Management of the period before spawning

In general, spawning of sea cucumber is performed from late May to July, but artificial seedling production of sea cucumber using the method of managing the ginseng of the present invention has an advantage of early production of seedlings. During the low-temperature management period, the temperature of breeding was lowered to 8°C, and then the temperature was raised to 18°C until spawning.

As shown in B and C of FIG. 2, the water temperature is raised at 8° C., wherein the temperature is raised by 0.5° C. every week for 3 weeks, and then heated up to 9.5° C. for 3 weeks (4), and 1° C. by step (4). It consists of a step (5) of raising the temperature to 17.5°C to 18°C for 8 weeks by heating, and a step (6) of maintaining the temperature at 18°C from the step (5) to the spawning induction. During this period, by raising the temperature of the livestock, sea cucumbers prepare for maturity in preparation for the arrival of spawning seasons regardless of the natural season.

3.3 Spawning period management

Figure 4 is a photograph showing a method for managing the spawning period in the management method of the ginseng of the present invention. The sea cucumbers managed during the entire spawning period can produce fertilized eggs through spawning and fertilization through spawning stimulation. The scattering stimulation is performed by general interstitial stimulation, surface stimulation and 5°C rising water temperature stimulation. For interstitial stimulation, the entire amount of seawater in the breeding tank is drained and exposed to room temperature for 30-40 minutes. Subsequently, surface irritation was given by spraying breeding water on the surface of the ginseng, and water temperature stimulation was provided by filling the water tank with 22~23°C, which is 5°C higher than the control temperature of 18°C, before the spawning.

Normal sea cucumber spawning occurs once a year, and by spawning stimulation, eggs and sperm of the gonads are released regardless of maturity. The sea cucumber eggs, which are mature and easy to fertilize, are characterized by a transparent and smooth surface, but the immature eggs have a warm color and are not smooth. When spawning through the management method of the ginseng of the present invention, only a part of the eggs are released by the spawning stimulation. At this time, the maturity of the spawning eggs is high, and the fertilization rate is very high compared to the spawning by the ginseng by conventional natural harvesting.

After the first spawning, the moss is spawned again several times by repeated spawning stimulation after 7-10 days of exposure in a water temperature environment of 18℃ again. Through experimental observations, in this way, a single ginseng individual spawned enough mature eggs up to 5 times, and all the spawned eggs were mature enough to have high fertilization rates.

Therefore, the amount of spawning by general natural harvesting spawns 2 to 3 million eggs per 1 moss, whereas the moss managed by the method of managing the moss according to the present invention spawns 2 to 5 million eggs per 1, It was found that the egg shedding efficiency was more than 160% than the existing method. Also, it has been confirmed that it is advantageous for mass production of high-quality seedlings due to high fertilization

It was.

By the management method of the ginseng according to the present invention, the period of artificial seedling production of sea cucumber can be extended from that of the conventional method. In other words, artificial seedling production of sea cucumbers from naturally harvested seedlings is possible after the harvesting of seedlings from late May to July from November to November, but the seedlings managed by the management method of seedlings according to the present invention By using, you can get the fertilized egg from March to September of the sea cucumber at the desired time, and the seedling can be shipped from August to November.

The size of the seedlings is also based on the existing production method, but the size of the ginseng is 1 to 3 cm and the weight of 0.5 to 2 g is shipped. Can be obtained by

After the spawning is about 5 times a year, the ginseng is transferred to a natural water tank and managed according to the natural water temperature without heating or cooling. Subsequently, water temperature management will start in October or November according to the production plan for the next year's artificial seedlings.

3.4 Feed management

Figure 5 is a photograph showing a self-produced dry solid feed for feed management of ginseng. Conventional sea cucumbers for the production of artificial seedlings of natural sea cucumbers are collected and used naturally, and after spawning, they are dead, and there is no preservation of the mother sea cucumbers. Therefore, there was no management method of feed for preservation and management of ginseng. Therefore, the present inventors have separately produced and supplied a feed for spawning for the production of artificial seedlings for the production of artificial seedlings for the supplementation of spawning protein compared to a common sea cucumber farming designed for weight gain.

3.4.1 Feeding for general ginseng

The feed for mossam is 10% by weight of insects, 5% by weight of capsicum, 4% by weight of kelp, 3% by weight of seaweed, 2% by weight of auditory powder, 6% by weight of protein feed (abalone powder, scallops, pearl oyster meat powder), upbringing feed 20% by weight, and 50% by weight of fine surface pearls containing diatoms were kneaded, fermented for 12 hours, sliced to 5ㅧ7cm, and dried dry solid feed was used. At this time, the protein content was set to be 20% or more, and nutrients were strengthened with additives such as spirulina, edible induction yeast and digestive agents, and vitamins, and were supplied 3 to 6% of body weight twice a day.

3.4.2 Supply of feed for spawning ginseng

Sea cucumbers, which have reached the spawning season, need to supply more protein and other nutrients than other times to spawn healthy eggs in large quantities. Through a lot of preliminary experiments, it has been observed that from 15 days before spawning can be spawned by stimulation, it is necessary to supply the feed for the fertilizer for the spawning season with protein reinforcement for energy supply for maturation and spawning.

As a result of observing and comparing the behavior and feeding activity of sea cucumber regularly during the pre-sperm management period, the behavior of sea cucumber is examined and compared. It is desirable to prepare the feed for the laid eggs of the spawning season, and it is better to replace the protein with the feed for the laying eggs of the spawning season when the water temperature is 16~18℃ in the step (5) of the period management before spawning. It was confirmed to be important.

As the feed for spawning ginseng, the yolk of boiled eggs was used for mixing the whole feed mix with egg yolk in a weight ratio of 1:0.2. In other words, 50% of fine surface pearls on the west coast containing diatoms, larvae, capsicum, kelp, seaweed, auditory powder, protein feed (abalone powder, scallop, pearl oyster meat powder), fodder feed, hair growth (digestion aid), diatoms Yeast, liver yeast, marine red yeast, fermented for 12 hours, sectioned to 5 x 7 cm, and dried dry solid feed was used.

At this time, the protein content was set to be 20% or more, and nutrients were enhanced with additives such as spirulina, appetite-inducing yeast, digestive agents, and vitamins, and were supplied 3 to 6% of body weight twice a day.

4. Early seedling production of sea cucumber

4.1 Separation and separation of fertilized eggs

Figure 6 is a photograph showing the production process of artificial seedlings produced by using the ginseng managed by the management method of the ginseng of the present invention. Fertilized eggs fertilized by spawning and fertilization are collected and separated into nets, and then divided into fertilized egg tanks. From the next day after fertilization, fertilized eggs are filled with seawater every day so that fresh brooding water is continuously supplied.

7 is a photomicrograph showing the fertilized egg and the hatching process obtained according to the method for producing early seedling of sea cucumber of the present invention. A is a fertilized egg, B is 2~16 cell phase, C is a cyst, and D is auriola state. In one experimental example of the present invention, a fertilized egg was obtained more than 2 months earlier than the occurrence of a fertilized egg during normal sea cucumber seedling production, and as shown in FIG. 7, most of the fertilized egg produced was generated.

Compared to the general sea cucumber seedling production that spawns only once a year, it is believed that only the matured eggs are spawned about 5 times, so the fertilization rate is high compared to the amount of spawning, and most of the fertilized eggs are thought to grow into ginseng.

8 is a photograph showing that the condition of the stomach and intestine is occurring well in the sea cucumber larvae produced by the method for early seedling production of sea cucumber according to the present invention. The best way to check the health of sea cucumbers in sea cucumber farming is to observe the condition of the stomach and intestines of the sea cucumbers and healthy eating activities.

4.2 Management of hemorrhoids development

Figure 9 is a photograph showing the development management of chisam according to the method of early seedling production of sea cucumber according to the present invention. By changing the necessary aquaculture device according to the growth of chisam, it is possible to stably secure a good quality sea cucumber seedling.

4.2.1 Sea cucumber farming equipment necessary for growth of chisam

10 is a perspective view showing a sea cucumber farming apparatus of the present invention, FIG. 11 is a plan view, FIG. 12 is a front or rear view, and FIG. 13 is a left or right side view. In the sea cucumber farming apparatus of the present invention, one or more wave boards can be stored horizontally with the bottom surface of aquaculture farms at the bottom of the upper wave panel holder part 100 so that a plurality of wave boards growing by attaching sea cucumbers can be formed perpendicular to the bottom surface. The lower wave plate holder portion 200 having a receiving portion so as to be made is integrally coupled with the upper wave plate holder portion, the bottom of the lower wave plate holder portion may be formed by a base 300 is formed. It is appropriate that the height of the pedestal is formed at a height that is not affected by aquaculture sea cucumbers accommodated in the lower slate holder portion with sludge or pearls on the bottom of the fish tank.

The slate is attached to the slate, which is grown in the slate or bone structure shape installed in a conventional land sea cucumber farm, and is grown on the larvae. The slate for the initial ssam is stored in the lower slate holder and horizontal to the bottom of the culture tank. Chisamun, which has been laid down and has been incubated for 1 month after hatching, can increase and move the amount of sea cucumber by moving and storing the waveboard in the upper wavelet holder so that it can be installed in a vertical or constant slope with the bottom of the culture tank. Through this process, the muscles of the protruding part of the sea cucumber can be developed to form a good shape, thereby increasing the size and weight of the sea cucumber.

The upper wave plate holder portion 100 of the present invention is a vertical member of a predetermined length connected to the horizontal and vertical members connected to the horizontal and vertical members forming the upper surface and the upper surface of the rectangular frame shape is opened by connecting the lower wave plate holder portion It is integrally combined to form a structure having an inner space portion of the upper and lower straits.

The vertical members of the left and right surfaces of the upper wave plate holder portion are inclined at an angle between 65 and 75 degrees toward the directions facing each other, have a downward converging structure of the upper and lower strait, and are integrally coupled to the upper inner surface of the lower wave plate holder portion.

Accordingly, a wave plate holder is formed at regular intervals so that the upper wave plate can be fixed to one or more spaces in the space separated by a certain distance formed by the vertical members of the left and right sides. The wave plate holder is formed with an angle between the bottom and the inclined angle of 65 to 75 degrees, such as vertical members on the left and right sides, so that the angle formed by the wave plate holder in the front and rear directions can be formed at an angle in the range of 60 degrees to 75 degrees. have.

The angle formed by the wave plate holder in the front and rear directions may be formed at an angle in a range of 60 degrees to 70 degrees, and preferably, an angle of 65° is appropriate. By forming a certain angle as described above, one or more wave plates are stored between the wave plate holder and the inclination angle having a certain angle formed between the wave plate holders to provide an attachment surface of sea cucumber. The 65° described at the preferred angle is a structure that enables sea cucumbers attached to the waveboards stored in the waveboard holder to be stably attached and maximizes storage efficiency.

The lower wavelet holder portion 200 formed at the lower portion of the upper waveplate holder portion forms a rectangular parallelepiped shape by a combination of a vertical member and a horizontal member, and on the front or rear side, a wavelet receiving portion is formed so that the lower wavelet can be received horizontally with the bottom surface. do.

The wavelet receiving portion may be formed with one or more spaces in multiple stages such that one or more lower wave plates are accommodated in multiple stages, or one or more storage receiving portions can be formed so that one or more lower wave plates can be stored side by side in one layer.

At the bottom of a typical farm, aquaculture sludge, such as aquatic organism waste and feed debris, is settled and decays or various parasites or viral germs contained in pearls are distributed. It is close to %. However, the sea cucumber farming apparatus of the present invention provides a space where sea cucumbers can be attached horizontally and vertically at the same time, and even if the sea cucumbers attached to the upper slate fall due to a decrease in the flow rate or adhesion of the breeding water inside the farm, the lower part is not the bottom of the farm. It can be moved downwards to the wave plate stored in the wave plate holder portion to prevent it from falling to the bottom of the water tank, and can be easily raised and attached again to the wave plate of the upper wave plate holder portion formed on the top.

In general, in a farm or land tank, food is supplied to the upper part, and in the case of food, the amount of aquaculture organisms may decrease due to a small amount of aquaculture mounted on the upper slate by collecting or sedimenting it to the bottom of the farm. Therefore, the sea cucumber food is precipitated on the wave plate stored in the lower wave plate holder portion of the present invention, so that the sea cucumber does not have a risk of mortality, and at the same time, it is easy to feed the food.

In addition, the upper wave plate holder portion and the lower wave plate holder portion of the present invention allows the flow of water flow to be distributed in a fish farm where a certain flow of water flows, so that the cultured sea cucumber is not stressed in the inner space fixed inside the upper and lower wave plate holder portions. It is possible to maintain the water flow, so the water flow is quick on the outside of the wavelet holder to facilitate sludge removal, while the water flow is relatively slow on the inside to prevent the inhibition of adhesion of farmed sea cucumber and to reduce the water pressure stress.

In general, the upper wave plate fixed to the upper wave plate holder part is installed perpendicular to the bottom portion to maintain a constant adhesion of the cultured sea cucumber under the influence of gravity, and when the adhesion force is weak, the dropping rate increases to increase the number of cultured sea cucumbers to the lower wave plate. Although the adhesion density may be concentrated only at a certain place in the aquaculture apparatus due to inhabitation, Example 1 of the following sea cucumber farming apparatus may solve the problem.

14 is a perspective view of a sea cucumber farming apparatus according to Example 1, FIG. 15 is a plan view, FIG. 16 is a front or rear view, and FIG. 17 is a left or right side view. The vertical members on the left and right sides of the sea cucumber farming apparatus according to the first embodiment may be installed while being inclined and converging in a direction facing each other.

In the front or rear view, the slope formed in the left or right side direction may be formed at an angle in the range between 65 and 75 degrees between the bottom and the bottom. Accordingly, the spaced apart distances of the vertical members of the left and right sides may be fixed in a structure in which a slope is formed. In addition, the front and rear waveboard holders 110 formed in the separation space formed by the left and right vertical members are suitable to form an angle between the floor and 60 to 70 degrees. Preferably, an angle of 65 degrees is appropriate, but when 65 degrees is set, the adhesive force of sea cucumber attached to the slate plate or the bone structure plate accommodated in the wave plate holder is good, and the storage space of the wave plate is maximized.

As it is formed by forming a certain angle as described above, one or more slate plates or corrugated wave plates having a certain angle are formed between the wave plate holder 110 and the wave plate holder 110 to form an attachment surface of sea cucumber. The sea cucumber farming apparatus according to the first embodiment of the present invention can prevent aquaculture sea cucumbers from falling off the upper slate, and at the same time, increase the settling rate of food supplied to the upper opening and prevent the concentration of the farming equipment from being concentrated while increasing the growth amount. can do.

As the number of aquaculture sea cucumbers accommodated in the aquaculture apparatus of the present invention increases, excretions of aquaculture sea cucumbers inhabiting the upper wave panel may be precipitated to show a water turbidity such as a tank bottom layer. The sea cucumber farming apparatus according to Embodiment 2 of the present invention can reduce the turbidity of the lower slate.

18 is a front and side view of a sea cucumber farming apparatus according to a second embodiment of the present invention. In the sea cucumber aquaculture apparatus according to the second embodiment, a locking jaw 201 is formed on the front side of the lower wavelet holder portion, and the lower wavelet S is formed at a certain angle with the bottom portion to be stored and fixed on the opposite side surface. A gradient forming portion 202 can be formed. One end portion of the lower swash plate accommodated therein is mounted on the upper side of the gradient forming portion, and the other end portion can be prevented from escaping outside the lower slate holder portion by a locking jaw.

The predetermined angle is appropriate to form an angle between the bottom portion and 5 to 10°, which means that the attached aquaculture sea cucumber can be stably attached on the waveboard while the feces of the cultured sea cucumber can be collected along the slope to the bottom of the tank. However, if it is less than the above angle, sludge is difficult to collect to the bottom of the tank, and in more cases, it may be a factor that may impair the adhesion of the attached sea cucumber.

When the ginseng reaches about 0.5 g, the ginseng is moved from the phantom to the special mang. The special mange is a device that is made so that it can be settled when the feed, etc., is fastened by bundling several meshes such as nylon, and sea cucumber is attached to it to facilitate feeding. In addition, since it is easy to understand the activity and defecation status of Chisam, the amount of uptake is higher than that of continuous breeding on phantom and it can be easily selected according to the intestinal health of Chisam.

5. Comparison between general sea cucumber artificial seedling and early seedling of the present invention

When comparing the artificial seedlings of the sea cucumbers each produced by the natural seedlings by the management seedlings and the natural seedlings used once through natural harvesting according to the method for adjusting the production time of the artificial seedlings of the sea cucumber through the land management of the mother sea cucumber of the present invention, As follows.

In the case of general seedlings, at the time of supply, the weight of each seedling was 0.5-2 g, whereas the seedlings produced by the ginseng managed according to the method of the present invention supplied at the same time had a weight and size of 2-5 g. Differences in the size of seedlings also affect the duration and survival rate of sea cucumbers. In the case of general seedlings, the seedling period produced by the seedling management of the present invention was shortened by 6 to 12 months to 16 to 30 months, while the seedlings produced by the management of the present invention were grown over 36 months. In the case of seed farming, the existing 36-month farming period could be shortened to 24~30 months, and in the case of festival-style farming, it could be shortened to 16~24 months.

Through this shortening of the farming period, it is possible to improve the survival rate of sea cucumber and to ship the product early by reducing the number of times when it is done once or twice when it was done three times from stocking to shipment. In other words, the seedling production period of Korean sea cucumber was conventionally from late May to July, but by managing the ginseng according to the management method of the ginseng of the present invention, by producing artificial seedlings of sea cucumber, It is now possible to produce seedlings.

Producing superior quality sea cucumber seedlings by increasing the initial aquaculture period by changing the production time of artificial seedlings of the sea cucumbers by early production and production time control method through the land management of the mother sea cucumbers according to the present invention. It can be secured stably, realizes early seedling production of sea cucumbers, not only extends the period during which seedling production is possible, but also shortens the farming period of sea cucumbers, contributing to the increase in the income of sea cucumber farmers. There is this.
