Description

Sea cucumber culture method using artificial seedlings of sea cucumbers produced early through land management of mother sea cucumbers {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 culturing artificial seedlings of sea cucumbers produced early through land management of mother sea cucumbers. More specifically, the spawning date is to select excellent mother ginseng and to spawn earlier than normal sea cucumbers in the natural state through water temperature control and feed management. It relates to a sea cucumber culture method using early production of sea cucumber artificial seedlings, which includes controlling the production of fertilized eggs and growing them into ginseng.

Sea cucumber is an aquatic organism belonging to the class Holothuroidea in the Phylum Echinodermate, and it was named sea cucumber because its medicinal effect is the same as that of ginseng. The body is a long cylindrical shape from front to back, and there are several hump-shaped projections on the back. The front end of the body has an open mouth, with several tentacles around it, and an anus at the rear end. Also, most species have many thin tube feet on the underside, which they use to crawl under the sea. Species without crowns either float in the sea or live in sandy mud.

Sea cucumbers repeat a set life every year according to changes in water temperature or seasons. Appetite is strong and exercise is active around 8~16℃ of water temperature, and at 17~19℃, exercise is not active and appetite is decreased and digestive tract is atrophied. sleep. When eating, the tentacles around the mouth put mud or sand under the sea into the mouth to feed on organic sediments such as seaweeds, and the sand and excrement are expelled. When stimulated from the outside, the intestine is cut off and sent out of the anus, but it is regenerated because of its strong regenerative power.

Sea cucumber is rich in vitamins and minerals, so it relieves fatigue and invigorates the body. It is known to have restorative properties. In addition, sea cucumber contains a component called holotane that destroys bacteria and prevents blood clotting, so it has an anticancer effect. In addition to this, sea cucumber is considered the best tonic because it purifies the blood and enhances male sexual function.

In Korea, sea cucumber farming became active when the National Institute of Fisheries Science succeeded in producing the first artificial seedling of sea cucumber in Korea in 1990.

Conventionally, artificial seedling production of sea cucumbers consists of a method of inducing spawning and release of naturally harvested sea cucumbers through spawning stimulation and obtaining fertilized eggs to obtain seedlings. limited to July.

1. Conventional method

Mother sea cucumbers for artificial seedlings are collected and supplied from nature before seedling production, and after the excrement is completely discharged for about 3 to 4 days, spawn and release by methods such as interstitial stimulation, water temperature stimulation, and surface stimulation. , and the fertilized eggs are transferred to an incubator to hatch and grow.

The fertilized egg hatches and goes through the larval period, at which time the water temperature is maintained at 22~24℃, and it is fed as food for phytoplankton or concentrated products. Sea cucumbers go through the larval stages of auricularia, doriolaria, and pentactula, and are grown by implantation in papan at the larval stage of pentactula, and after several months, into 1 cm young sea cucumbers. will grow

In the conventional production of artificial sea cucumber seedlings, naturally harvested sea cucumber is used as the mother ginseng, and the mother ginseng stocked by natural collection is ovulated and released at one time regardless of the maturation of eggs and sperm in the gonad due to the stimulation of spawning. , so the fertilization rate is not high compared to the spawning amount. In addition, the number of fertilized eggs that can be secured per parent is limited because naturally harvested eggs complete all spawning with one spawning.

After being stocked with conventionally harvested seedlings, spawning and release are induced through spawning stimulation within 1 to 7 days, and seedlings after spawning and release are discarded. Therefore, the production period of seedlings is limited from late May to July, when sea cucumbers spawn, hatch and grow in their natural state. Therefore, if the seedlings are stocked and cultured at this time in the farm, there is a problem that the survival rate is reduced as much as it has three bottom periods until it is shipped.

The present invention advances the artificial seedling production time of sea cucumber, increases the initial culture period, and changes the culture method required according to the growth of ginseng. An early production method of sea cucumber that can be produced early by May was established.

2. ginseng Selection

The seedlings managed for the production of artificial seedlings are first collected and secured from nature. In general, sea cucumbers hatch naturally from the end of May to July, so the sea cucumbers used as mother ginseng are collected earlier than this by haenyeo between March and June. For the mother ginseng selected in the present invention, sea cucumbers naturally collected from Baengnyeong-do and Rodo, Chungcheongnam-do were purchased and used.

2.1 Appearance and in supper activity screening by

1 is a photograph showing the appearance of sea cucumbers to be used as mother ginseng. Among sea cucumbers collected from natural seawater, select those that have smooth surfaces, no scars, large, well-arranged projections, bright colors, and weigh more than 150 g per individual.

Naturally harvested ginseng was allowed to fast for one week after stocking in the tank. During this fasting period, feed feeding is stopped and the sea cucumber's intestines are emptied while water is returned using filtered seawater. After that, the compound feed was fed, and the feeding amount was 3% of the body weight of the sea cucumber.

2.2 for feed screening by

Conventional sea cucumber feed mixes powdered feed with pearls and sprinkles it on a water tank, and it is stacked at the bottom of the tank and the sea cucumber crawls and feeds. . In the selection step of mother ginseng and the method for producing early seedlings of sea cucumbers of the present invention, a section-type solid feed that can be used to determine the level of feeding activity and use the feeding activity for selecting seedlings is used during feeding. When 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, the sea cucumbers on the floor or wall are collected as feed for feeding. Only high individuals can be selected.

In addition, since the section-type solid feed is not easily dissolved in breeding water, a single seedling can come up and feed a piece of feed. Through this, excellent seedlings with high feeding activity are selected.

3. ginseng Controlling the production time of artificial seedlings through land management

In the past, there was a problem of lack of preservation properties, such as dying after fertilization of naturally harvested ginseng. Therefore, since the individual weight of sea cucumber used as parent ginseng is also covered only by natural collection, 150 g or more was used. However, sea cucumbers managed as mother ginseng for many years have a large amount of spawning and increased egg fertilization efficiency because the individual weight reaches 250 to 400 g.

The sea cucumbers selected after the natural collection are used as seed ginseng for artificial seedling production of sea cucumbers through the management of year-round water temperature, feed, water quality, etc. Of these, water temperature management is the most important for the management of seedlings.

Naturally, sea cucumbers spawn and release once from the beginning of May to July. Afterwards, if the water temperature in summer increases, they spend the winter and can spawn and release again the following year. It is a technical feature of the present invention to quickly recover the spawning ability of sea cucumbers and control the period through constant water temperature change while managing the water temperature corresponding to the natural environment of these seasonal changes in water temperature.

3.1 Low temperature period management

2 is a graph showing the water temperature management until spawning the next year after collecting or spawning mother ginseng in the method for producing sea cucumber early seedlings of the present invention. From A to C, the breeding water temperature of sea cucumbers is shown in chronological order. From June 1 to December 5, shown in blue, it is managed so that it corresponds to the natural water temperature. During this period, sea cucumbers are exposed to low-temperature environments as the water temperature gradually drops from summer, so the breeding water temperature is lowered slowly to create an environment in which the mother ginseng passes through the winter after spawning. Filtered and sterilized breeding seawater is adjusted to have appropriate dissolved oxygen, pH, and salinity, and is supplied by heating and cooling to an appropriate temperature through a heater.

At this time, the breeding water temperature is lowered from the natural water temperature to 16.5°C for 4 weeks (1), from the step (1) to 10.3°C for 4 weeks (2), from the step (2) to 8°C for 4 weeks (3) ) to lower the water temperature by 8 °C step by step. In general winter sea cucumber culture, it is possible to maintain 20~25℃ with general seawater or to be subjected to a lower water temperature in the natural environment. Confirmed.

Figure 3 shows the automatic temperature control equipment required for water temperature management of ginseng. The above-mentioned breeding water temperature is to advance the spawning cycle of mother ginseng before the natural state, and it is important to increase the correct water temperature because it includes a process of warming the water temperature despite seasonal changes in the natural state. Therefore, the water temperature must be precisely controlled by employing an automatic temperature control facility, and the temperature is lowered or increased within a certain period of time.

3.2 Pre-spawning period management

Although general spawning of sea cucumbers takes place from late May to July, artificial seedling production of sea cucumbers using the mother ginseng management method of the present invention has the advantage of producing seedlings early. After lowering the breeding water temperature to 8 ℃ during the low temperature management period, the temperature is raised to 18 ℃ until spawning induction.

As shown in B and C of FIG. 2, the water temperature is raised from the breeding water temperature of 8 ° C. At this time, the temperature is raised by 0.5 ° C every week for 3 weeks to 9.5 ° C for 3 weeks (4), 1 ° C every week from the step (4) It consists of a step (5) of raising the temperature to 17.5°C to 18°C for 8 weeks, and maintaining the temperature at 18°C from step (5) to induction of spawning (6). During this period, the sea cucumber prepares for sexual maturity in preparation for the arrival of the spawning season regardless of the natural season through the change in the temperature of the breeding water.

3.3 Spawning Period Management

Figure 4 is a photograph showing the method of managing the spawning period in the management method of mother ginseng of the present invention. Sea cucumbers managed during the pre-spawning period can produce fertilized eggs by spawning and fertilization through spawning stimulation. Scattering stimulation is performed by general interstitial stimulation, surface stimulation, and water temperature stimulation at 5°C. To stimulate intercalation, drain the entire amount of seawater from the breeding tank and expose it to room temperature for 30 to 40 minutes. Thereafter, breeding water was sprayed on the surface of the mother ginseng to give surface stimulation, and water temperature stimulation was given by filling the tank with breeding water at 22-23°C, which is 5°C higher than the 18°C control temperature for the pre-spawning period.

Normal sea cucumber spawns once a year, and the eggs and sperm of the gonads are released regardless of whether they are mature or not by the stimulation of spawning. Sea cucumber eggs that have matured enough and are easy to fertilize are characterized by being transparent and smooth on the surface, but immature eggs are cloudy and not smooth in warm color. In the case of spawning through the management method of mother ginseng of the present invention, only a portion of the eggs are released by the scattering stimulus, and the maturation of the spawning eggs is high at this time, so the fertilization rate is very high compared to scattering by mother ginseng by natural harvesting.

After one spawning is finished, the mother ginseng is again exposed to a water temperature environment of 18℃ for 7 to 10 days, and then spawned several more times by repeated spawning stimulation. Through experimental observation, one mother ginseng individual spawned sufficiently mature eggs up to 5 times in this way, and all of the eggs laid were sufficiently mature, resulting in a high fertilization rate. Therefore, in contrast to the spawning amount by general natural collection, 2 to 3 million eggs per mother ginseng were laid, while the mother ginseng managed by the management method of the present invention spawned 2 to 5 million eggs per one mother ginseng, It was found that the fertilization efficiency was more than 160% compared to the conventional method. In addition, it was confirmed that the high fertilization rate is advantageous for mass production of high-quality seedlings.

By the method for managing mother ginseng according to the present invention, the period of artificial seedling production of sea cucumber can be extended than the period by the conventional method. That is, in the artificial seedling production of sea cucumber from naturally harvested seedlings, the harvest of fertilized eggs is from the end of May to July, and the seedlings can be shipped after November, but the seedlings managed by the management method of seedlings according to the present invention. You can obtain fertilized eggs at any time from March to September of sea cucumber, and the delivery time of seedlings is possible from August to November.

The size of seedlings According to the existing production method, ginseng with a length of 1 to 3 cm and a weight of 0.5 to 2 g is shipped. However, when seedlings are produced according to the present invention, seedlings of 3 to 5 cm in length and 2 to 5 g in weight are produced in large quantities. can be obtained with

After spawning 5 times a year, the mother ginseng is transferred to a natural water tank and managed according to the natural water temperature without heating or cooling. After that, according to the artificial seedling production plan for the next year, water temperature management starts from October or November.

3.4 Feed management

5 is a photograph showing a dry solid feed produced by itself for feed management of ginseng. In the related art, seed ginseng for artificial seedling production of sea cucumber was naturally collected and used. Therefore, there was no feed management method for the preservation and management of ginseng.

Therefore, the present inventors separately produced and supplied a feed for seedlings for spawning season for artificial seedling production to supplement protein supplementation for general seedlings for growth of gonads compared to common sea cucumber aquaculture designed for weight gain.

3.4.1 General ginseng feeding

Feed for ginseng is 10% by weight of caterpillars, 5% by weight of mother-of-pearl, 4% by weight of kelp, 3% by weight of seaweed, 2% by weight of auditory powder, 6% by weight of protein feed (abalone powder, scallop, pearl mussel powder) 6% by weight, breeding feed 20% by weight, 50% by weight of fine surface pearls on the west coast containing diatoms were mixed and kneaded, fermented for 12 hours, cut into 5 × 7 cm, and dried dry solid feed was used. At this time, the protein content was set to be 20% or more, and nutrition was fortified with additives such as spirulina, edible oil-derived yeast, digestive agents, and vitamins, and was supplied at 3 to 6% of body weight twice a day.

3.4.2 Spawning season ginseng feeding

Sea cucumbers that have reached the spawning season must provide more nutrients such as protein than at other times to lay a large number of healthy eggs. Through many pre-experiments, it was observed that protein-reinforced feed for seedlings during the spawning season should be supplied to supply energy necessary for sexual maturity and spawning from 15 days before spawning is possible due to spawning stimulation.

As a result of continuously observing the behavior and feeding activities of sea cucumbers during the pre-spawning management period and periodically harvesting and comparing the gonads, the behavior of sea cucumbers shows that if there are more individuals who shake their heads while climbing the wall of the tank, the water temperature is lowered and the protein is reinforced. It is desirable to prepare feed for seedlings in the spawning season, and in step (5) of 3.2 pre-spawning period management, when the water temperature is 16~18℃, it is recommended to replace the feed with protein-reinforced feed for seedlings during spawning season to produce good eggs and fertilized eggs. was confirmed to be important.

For the feed for seedlings in the spawning season, the whole feed mixture of boiled egg yolk and egg yolk was mixed in a weight ratio of 1:0.2 to general feed for seedlings. That is, 50% of fine surface pearls on the west coast containing worms, mother-of-pearl, kelp, seaweed, auditory powder, protein feed (abalone powder, scallops, pearl mussel meat powder), growth feed, hair transplantation (digestive aid), diatoms, dry Yeast, liver yeast, marine red yeast, after addition, fermented for 12 hours, sliced into 5×7 cm, and dried dry solid feed was used.

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

4. Early seedling production of sea cucumber

4.1 Separation and division of fertilized eggs

6 is a photograph showing the production process of an artificial seedling produced using the seedling managed by the seedling management method of the present invention. Fertilized eggs fertilized by spawning and ejaculation are collected in a net, separated, and then fertilized in a fertilized egg tank. From the next day after hatching of fertilized eggs, fill with seawater every day to ensure that fresh breeding water is continuously supplied.

7 is a photomicrograph showing the fertilized egg and hatching process obtained according to the method for producing an early seedling of sea cucumber of the present invention. A is a fertilized egg, B is a 2-16 cell stage, C is a gastrulation stage, and D is a photograph showing the state of auriolaria. In an experimental example of the present invention, fertilized eggs were obtained more than 2 months earlier than the generation of fertilized eggs during normal sea cucumber seedling production, and as shown in FIG. 7 , most of the produced fertilized eggs occurred.

Compared to the general production of sea cucumber seedlings, which spawn only once a year, only mature eggs are laid about 5 times, so the fertilized egg acquisition rate is high compared to the spawning amount, and it is thought that most of the fertilized eggs grow into ginseng.

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

According to the management method of the mother ginseng of the present invention, the artificial seedling production period of sea cucumber, which was conventionally between late May and July, can be produced between March and September. By shortening the culture period, the survival rate of sea cucumbers can be improved and products can be shipped early by reducing the number of times from 3 times of ginseng stocking to 1 or 2 times.

4.2 ginseng management of development

9 is a photograph showing the development management of ginseng according to the method for producing seedlings of sea cucumber early according to the present invention. By changing the necessary aquaculture equipment according to the growth of ginseng, excellent sea cucumber seedlings can be stably secured.

4.2.1 ginseng Sea cucumber farming equipment necessary for growth

10 is a perspective view of a sea cucumber culture 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 culture apparatus of the present invention, one or more wave plates can be accommodated in the lower part of the upper wave plate holder part 100 so that a plurality of wave plates to which sea cucumbers attach and grow can be formed perpendicular to the bottom surface. The lower corrugated plate holder part 200 having the receiving part is integrally coupled with the upper corrugated plate holder part, and the pedestal 300 may be formed at the lower edge of the lower corrugated plate holder part. It is appropriate that the height of the pedestal is formed at a height at which the cultured sea cucumber accommodated in the lower wave plate holder is not affected by sludge or pearls on the bottom of the aquarium.

The wave plate is a slate or bone structure that is installed in a conventional land sea cucumber farm, and the ginseng grown through the larval stage is attached to the wave plate and managed. The amount of movement of sea cucumbers can be increased by moving and storing in the upper part of the chimney holder so that the chiseng can be managed by laying it down and being installed one month after hatching, vertically or at a certain inclination to the bottom of the aquaculture tank. Through this process, the muscles of the protrusion of the sea cucumber can be developed to form a good shape, and the size and weight of the sea cucumber increase.

In the upper wave plate holder part 100 of the present invention, a vertical member of a certain length connected to the horizontal and vertical members forming the upper surface and the upper surface of the rectangular frame shape with the upper part opened by connecting the horizontal and vertical members is the lower wave plate holder part and It is integrally coupled to form a structure having an inner space of the upper and lower valleys.

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

Accordingly, in the space formed by each of the left and right vertical members at a predetermined distance, wave plate holders are formed at regular intervals so that one or more upper wave plates can be fixed to the spaced space. The wave plate holder, like the left and right vertical members, has an angle between the inclined floor and the floor of 65 to 75 degrees, so that the angle formed by the wave plate holder in the front and rear directions is in the range of 60 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 the range of 60 degrees to 70 degrees, and preferably, it is appropriate to form an angle of 65 degrees. By forming at a certain angle in this way, one or more wave plates are accommodated between the wave plate holder and the inclination angle having a certain angle formed between the wave plate holder, thereby providing an attachment surface of the sea cucumber. The 65° described as the preferred angle is a structure that allows the sea cucumber attached to the wave plate accommodated in the wave plate holder to be stably attached and the storage efficiency is maximized.

The lower corrugated plate holder part 200 formed under the upper corrugated holder part forms a rectangular parallelepiped shape by combining a vertical member and a horizontal member, and a corrugated plate receiving part is formed on the front or rear side so that the lower corrugated plate can be received horizontally with the floor surface do.

The wave plate accommodating part may be formed with one or more space portions in multiple stages to accommodate one or more lower corrugated plates in multiple stages, or one or more accommodating accommodating units may be formed so that one or more lower corrugated plates can be accommodated side by side in one layer.

Cultured sludge such as aquaculture excrement and feed waste is deposited on the bottom of a typical farm, and various parasites or viral germs contained in pearls or other parasites or viral germs are distributed. % will die off. However, the sea cucumber culture 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 cucumber attached to the upper wave plate falls off due to a decrease in the water flow or adhesion force inside the farm, the bottom part of the farm is not the bottom part. The wave plate accommodated in the wave plate holder unit moves down to prevent it from falling to the bottom of the water tank, and it can be easily re-attached to the wave plate of the upper wave plate holder unit formed at the top.

Normally, in an open-air farm or onshore tank, food is supplied to the upper part, and in the case of food, the water flow of the farm is collected or settled at the bottom of the farm, so the amount of aquaculture placed on the upper wave plate is small, which may decrease the growth of aquaculture organisms. Accordingly, sea cucumber feed is precipitated in the wave plate accommodated in the lower wave plate holder unit of the present invention, so that there is no risk of sea cucumber dying and at the same time, it is possible to easily feed the food, thereby increasing the growth rate as well as increasing the feeding efficiency.

In addition, the upper wave plate holder part and the lower wave plate holder part of the present invention distribute the flow of water in a farm where the flow of a certain water flow is made, so that the cultured sea cucumber does not receive stress in the internal space fixed inside the upper and lower wave plate holder parts. It is possible to maintain the water flow, so the water flow is fast outside the wave plate holder, so it is easy to remove the sludge, while the water flow inside is relatively slow, which has the effect of preventing inhibition of adhesion of cultured sea cucumbers and reducing hydraulic stress.

In general, the upper wave plate fixed to the upper wave plate holder part is installed perpendicular to the bottom part, and it is necessary to maintain a certain adhesion force of the cultured sea cucumber under the influence of gravity. Inhabited, the adhesion density can be concentrated only in a certain place in the aquaculture apparatus, but the following sea cucumber culture apparatus Example 1 can solve this problem.

14 is a perspective view of a sea cucumber culture 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 of the left and right sides of the sea cucumber culture apparatus according to Example 1 have an inclination in a direction facing each other and converge, but may be installed with an inclination in the front or rear direction.

The slope formed in the left or right direction in the front or rear view may be formed at an angle in the range of 65 degrees to 75 degrees between the floor and the inclination. Accordingly, the spaced space of a predetermined distance between the left and right vertical members may be fixed in an inclined structure. In addition, it is appropriate that the wave plate holder 110 in the front-rear direction formed in the space formed by the left and right vertical members forms an angle between the floor and 60 to 70 degrees. Preferably, the angle of 65 degrees is appropriate, but when 65 degrees is set, the adhesion of the sea cucumber attached to the slate plate or the bone structure plate accommodated in the wave plate holder is good, and it becomes a structure in which the receiving space of the wave plate can be formed to the maximum.

By forming at a certain angle in this way, one or more slate plates or corrugated plates of bone structure are accommodated between the inclination angles having a certain angle formed between the wave plate holder 110 and the wave plate holder 110 to form the attachment surface of the sea cucumber. The sea cucumber culture apparatus according to Example 1 of the present invention can prevent the cultured sea cucumber from falling off from the upper wave plate, and at the same time increase the feeding rate supplied to the upper opening to increase the growth amount and prevent the concentration of the attachment density of the culture apparatus can do.

As the number of cultured sea cucumbers accommodated in the aquaculture apparatus of the present invention increases, the excrement of cultured sea cucumbers living in the upper wave plate may be precipitated on the lower wave plate, and thus water quality turbidity like the bottom of the tank may be exhibited. The sea cucumber culture apparatus according to Example 2 of the present invention can reduce the turbidity of the lower wave plate.

18 shows a front and side view of a sea cucumber culture apparatus according to Example 2 of the present invention. In the sea cucumber culture apparatus according to Example 2, a locking jaw 201 is formed on the front side of the lower wave plate holder part, and the lower wave plate (S) forms an inclination at a certain angle with the bottom part on the opposite rear side to be accommodated and fixed. A possible gradient forming portion 202 may be formed. One end of the lower wave plate accommodated therein is mounted on the upper side of the gradient forming part, and the other end can be prevented from being separated from the lower wave plate holder part by the clasp.

It is appropriate that the predetermined angle forms an angle between the bottom and the bottom of 5 to 10°, which allows the attached cultured sea cucumbers to be stably attached on the wave plate, while the excreta of the cultured sea cucumbers can be collected along the slope to the bottom of the tank. However, if it is less than the above angle, it is difficult for the sludge to be collected at the bottom of the tank, and if it is more than that, it may be a factor that may impair the adhesion of the attached cultured sea cucumber.

5. Early seedlings produced ginseng used festival and field farming

When the ginseng reaches about 0.5 g, move the ginseng to an open-air or festival-style farm. The movement of ginseng can move the sea cucumber culture apparatus of the present invention to which the ginseng is attached as it is to an open-air farm or a festival-style farm, and the ginseng can be moved from the sea cucumber culture apparatus to a special net. A special mesh is a device made by tying up several layers of mesh such as nylon, so that it is settled when feed, etc. In addition, in the process of draining the breeding water, only chisam can be recovered and transferred to an open-air farm or a festival-style farm by directly spraying it.

Open-air farms can use river sites, triangular land, burak land, oil, salt fields, or farmland, and can use waste salt fields or reclaimed farmland that can facilitate the inflow and outflow of seawater using tides or pumps. After securing an internal accommodation space to have a certain depth and width in the open-air farm, cover the bottom of the open-air farm with the cover of the farm so that the bottom of the farm and the aquaculture space are separated. In this case, a waterproof tent, HEPE, etc. can be used for the farm cover. Covering the farm cover on the bottom of the open-air farm can be appropriately selected depending on the environment in which the farm is built.

In other words, when using a closed salt farm as a farm, it can be used without a farm cover because the bottom is well-organized. One or more sea cucumber culture apparatuses are connected and fixed to the open-air farm. At this time, the arrangement of the sea cucumber culture apparatuses is preferably arranged in a zigzag form so that they are not side by side. The zigzag arrangement acts on the feed water flow in the open field farm.

Diatoms are used to feed sea cucumbers in open-air farms, and diatoms are included in the seawater, so once attached, food can be continuously produced by photosynthesis. can provide a space for the sea cucumber to attach.

Therefore, the sea cucumber culture equipment is arranged in a zigzag manner, and as the breeding water flowing through the open-air farm passes around the sea cucumber culture equipment, the flow velocity decreases due to friction with the sea cucumber culture equipment, and turbulence occurs between the sea cucumber culture equipment, and the seawater comes into contact with the sea cucumber shelter. will increase the time. In this case, it is possible to increase the possibility of attaching diatoms contained in seawater to attach to the sea cucumber culture apparatus without passing through the sea cucumber culture apparatus as it is, thereby increasing the food retention rate in the sea cucumber culture apparatus.

That is, as the water flow comes into contact with the sea cucumber culture device, the flow rate is slowed and dissipated into a small water current, and the direction of the breeding water is also switched from one direction to multiple directions. Accordingly, the breeding water can flow evenly throughout the tank, and the food retention rate is dramatically increased.

The artificial seedlings of sea cucumbers produced by the seedlings used once through natural collection with the artificial seedlings produced according to the method for controlling the production time of sea cucumber artificial seedlings through land management of the mother sea cucumber of the present invention are as follows. .

In the case of general seedlings, one seedling weighed 0.5 to 2 g at the time of supply, whereas seedlings produced by seedlings managed according to the method of the present invention supplied at the same time were 2 to 5 g in weight and larger in size and weight. The difference in seedling size also affects the cultivation period and survival rate of sea cucumbers. In the case of general seedlings, they are grown and shipped for more than 36 months, whereas in the case of seedlings produced by the seedling management of the present invention, the culture period was shortened by 6 to 12 months to 16 to 30 months. In the case of seeding aquaculture, the cultivation period of the existing 36 months was 24 to 30 months, and in the case of the festival type aquaculture, the cultivation period could be shortened to 16 to 24 months.

According to the method of controlling the early production and production time through land management of the mother sea cucumber according to the present invention, the artificial seedling production time of sea cucumber is advanced, the initial culture period is increased, and excellent sea cucumber seedlings are obtained by changing the necessary aquaculture equipment according to the growth of the ginseng. Industrial applicability as it can be secured stably, realize early seedling production of sea cucumbers, extend the period for seedling production, and shorten the cultivation period of sea cucumbers, thereby contributing to the income increase of sea cucumber farmers. There is this.
