The present invention relates to a method for cultivating a garlic saffron seedling intermediate growing step. More specifically, a spray pattern is selected on the tidal flats, a dike structure capable of holding a certain level of seawater is formed, and a polyurethane-made dike-preventing cloth is placed on the tidal flats so as not to lose the dike, Prevent micro-sized spores from being lost to the ocean. This is a method for intermediate cultivation of a goryeo mussel artificial seedlings using tidal flats, which can increase the survival rate of spatulas in a spraying pond by storing the food organisms while blocking the intrusion of pirate creatures by a barrier membrane.

Sinonovacula constricta is an edible bivalve distributed in Korea, China and Japan as mollusca, Bivalvia, Heterodonta, and Novaculinidae. Especially in Korea, .

However, in recent years, the production of reclaimed land for reclamation, coastal reclamation and development, changes in the marine environment, and aquaculture contamination have been caused by the abundance of natural resources. And the amount of resources is continuously decreasing due to the poor seed production.

Especially, the size of 8cm or more gill mussel is exported to Japan, but because the amount of resources is insufficient, production techniques are being developed in large quantities of gill mash artificial seedling in the aquarium.

However, even if a large amount of artificial seeds can be produced in the aquaculture tank, the yield per unit area is very poor due to the high rate of deformation occurring in the middle stage of the field, and it takes enormous cost to cultivate and manage the food biomass The value of the artificial seedlings is lowered. Therefore, there is a need for a seedling production method capable of increasing the survival rate of the artificial seedlings in the intermediate growing stage.

One. Giraffe  Artificial seed production

The reproductive cycle of the garlic mash consists of five consecutive stages such as an initial active period, a late active period, a ripening period, a partial spawning period, a degeneration and an inactivity period. The artificial fertilization process, It starts by selecting the mother-parts and preparing them in a stable state.

Prepared mosquitoes regulate the scattering environment by controlling the salinity concentration and the combination of the early stimulation and the low temperature stimulation, and the artificial scattering is induced, resulting in a large amount of irregularity and irregularity. The eggs and spermatozoa are fertilized artificially, and when fertilization is confirmed, the foreign body is removed through the sera and the surplus sperm is removed, and the sperm is allowed to stand until it is hatched.

The hatched larvae grow on the stubble during the floating, the deposition and the intermediate growth stages, and the artificial seedlings of the larval stage are kept in the aquatic tanks until they grow to 1 ~ 2mm. In the intermediate stage, the sparrows grown at 1 mm in the deposition stage were transported to a natural farm such as a tidal flat, and the sparrows were submerged in a calibrated plate at a predetermined diameter. The sparrows were grown to a size of 1-2 cm, .

However, when the spatula is sprayed on the tidal flats in the middle stage, most of the spatula can not adapt to the changes in the marine environment, or the survival rate is extremely low due to the harmful effect by the pirates. The size of the spatula is about 1 ~ 2mm, It is difficult to form intensive forms due to the occurrence of frequent loss at the initial stage of spraying.

2. The present invention Giraffe  How to grow in the middle

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a conceptual diagram of a method for cultivating an artificial seedling of the present invention using the tidal flats. The method of the present invention for cultivating an artificial seedling of the present invention comprises the steps of forming a trench to hold seawater for a certain period of time by selecting a spraying paper on the tidal flats and covering the trenches of the polypropylene- step; Removing foreign matters from the tidal-flat of the spraying papers to form a bottom of the spraying papers; Providing an anti-dust film on the inner periphery of the formed spray pattern structure; Installing a pirate biological intrusion barrier around the outer periphery of the spray structure; Spraying an artificial seedling spatula onto the sprayed spatula; And collecting the sprayed spatula and feeding the seedlings to the seedling.

Fig. 2 shows a step of forming a weft dike in the method of cultivating a mung bean paste artificial seedling using the tidal flats of the present invention. The step of forming the weft dike of the present invention may be composed of a weir structure forming step, a weft form forming step, and a weft loss prevention cloth applying step.

In the step of forming the dam structure, one or more spreading sheets are set on the tidal flats of a suitable area, a dam is formed on the edge of the spreading area, and a drainage channel is installed. The criterion for selection of the sprayed paper is a tidal flat with excellent flow of seawater due to tidal and ebb tide, and a dam is formed around the edge of the sprayed paper which is divided into a certain area.

The structure of the dam structure is constructed by plowing the tidal flats outside the spray area using a shovel. At this time, the tidal flats are formed with solid tidal flats in the lower layer rather than the tidal flats in the surface layer, forming the skeleton. The formed dam is at least 40-50 cm wide . The drainage channel is formed by a PVC pipe and an elbow with a diameter of 50 to 200 mm, and is installed in an L-shape on the dam, and is preferably installed for each single sparge.

In the step of forming the dam shape, the tidal flat is secondarily pushed back to the constructed dam structure to form the shape of the dam, and the height of the dam is made uniform. After a day passes, a part of the dam is discharged from the upper part by the fresh water and the seawater flow, but the skeletal form is maintained. In the present step formation step, So as to form a sturdy dam so as to have resistance to fresh water and sea water movement and at the same time to have a structure capable of always retaining a certain amount of seawater in the spray papers.

The height of the dam formed in this step is generally 40-50 cm higher than the bottom of the spray, and the height is calculated so that the depth of the sea water contained in the dam is always maintained at 20-30 cm. The terrain in which the spray paper of the present invention is formed is inclined due to the difference in the tide distance only, and it is appropriate to construct the height of the dam so that the height of the tide is slightly higher.

Fig. 3 is an enlarged photograph of a weir prevention cloth structure of the method of intermediate cultivation of a salted clam shell artificial seedling using the tidal flats of the present invention. The weir prevention cloth is formed to have a diameter corresponding to a weir structure diameter of at least 40-50 cm wide, and the material thereof is made of a polypropylene nonwoven fabric having a large pore size so that the seawater and the tidal flats can exchange oxygen.

In the present invention, the purpose and function of the dam is to divide a certain area of the soil and store the seawater. In addition, it plays a role of holding the food creature inhabited in the stored seawater so that the sea bass clam can be fed, The tidal flats have a temperature control function that prevents them from being directly affected by temperature changes in the air as they are stored during the tidal period. In addition, there is an effect to prevent invasion of the surrounding pirate food creatures because of the dam divided into a certain section.

It is appropriate to cover the upper part of the dam structure and to remove the air completely between the dam structure and the dam preventive cloth. The dirt-loss prevention cloth applying step is performed after the lapse of a day through the weft shape forming step, and the step of reinforcing a portion where the dam is likely to be lost is reinforced and the surface is smoothly formed, and then the step of applying a dirt-

In the position of the drainage channel, the drainage prevention cloth is cut so that drainage can be exposed, so that drainage can be easily performed, and both ends of the drainage passage are pushed into the vicinity of the tidal flats to be deeply fixed. Prevention of dam destruction The damming step prevents the loss of tidal flats that form dike structures in tidal flats exposed to marine environments such as tidal currents and wind waves, do.

By applying polypropylene nonwoven fabric with large pore size to the dam, it plays a role to hold the dam formed by the tidal flat material so that it can maintain its shape and the air circulation or oxygen supply to the inside of the dam and the outside of the nonwoven fabric is smoothly performed, Unlike the case of applying a nonwoven fabric which does not have the effect of preventing the tidal flats from rotting. In addition, the dam-proofing cloth of the present invention is made of polypropylene and has excellent solar transmittance and air permeability, thereby maintaining the structure of the dam. In addition, the nutrient that can be fed to the inside of the dam structure, There is an effect that the growth of the spore can be accomplished in a short time by naturally raising the seawater with the passage.

The step of forming the bottom of the spreading sheet includes a flattening operation for evenly spreading the inclined terrain of the spreading paper, and a work for removing foreign matter such as clamshells, rocks, and awareness in the spreading paper. If the topography of sprayed sparrows is uneven, or if there are a large number of clamshell rocks contained in the tidal flats, the flow of the algae will change and the spatula will collect in one place, which will cause unbalanced growth of the spore.

Since the unbalanced growth of individuals in the shellfish culture in general can cause a reduction in the survival rate of the entire inhabited aquaculture, the step of forming the bottom of the spray of the present invention must be carried out before spraying. The flattening work can be done by scraping or using a harrow, and after the flattening work, it is possible to remove the foreign matter by shaking the tidal flats in a collection net of 3 mm or less. Removal of foreign matter If the tidal flats are shaken in the collection net, the fine particles will escape through the collection net, and foreign matter can be easily removed.

Fig. 4 shows an antifouling film of the method for the intermediate cultivation of a sea bream clam shell using the tidal flats of the present invention. In the step of installing the anti-seizing film, at least one support column is installed at a predetermined interval while surrounding the edge of the spray pattern on the inside of the dam structure, and the anti-seize prevention film of 2-5 mm in mesh is attached to the support column on each support column. The initial size of sparrow to be sprayed on the dam is about 1 ~ 2mm, so it is very light.

The length of the anti-seizure prevention membrane is formed so as to include the periphery of the sprayer, and at the time of installation, the lower part of the anti-seizure prevention membrane should be deeply fixed to minimize the gap where the seizure can be lost to the outside. The sparrows sprayed on the spraying medium in the middle growing stage are 1-2mm in size from the aqueduct in the aquatic tank, and are lighter than those of other shellfishes. The sparrows can be lost due to the flow of the algae and the marine environment. It is possible to prevent the influence and the flow of the algae from being lost to the outside of the dam structure.

FIG. 5 shows a pirate biological invasion barrier of the method of intermediate cultivation of a salted clam shell artificial seed using the tidal flats of the present invention. The garnet shellfish artificial toothpastes require a device that can prevent intrusion into the inside of the sponge because of the severe dehydration of the pirate creatures such as crustaceans (crab), fishes (mullet, molasses), cephalopods (octopus,

The pirate biological intrusion shielding membrane of the present invention is installed at a distance of 5 m from the outer edge of the weir structure to surround the weir structure and separated from one another by at least one of the supporting posts. The pirate biological intrusion shielding membrane is connected to the support, So that the management of the spray area is facilitated.

The support is generally formed of a material capable of minimizing the influence of the marine environment such as wind and strong current. In the embodiment of the present invention, the support is formed by coating plastic on the bamboo. However, If the intrusion barrier can be fixed, it can be installed in various ways such as bamboo, wood, steel pipe.

The length of the Pirate biological invasion barrier is formed by the pirate biological invasion barrier surrounding the installed pillar and is formed on the outside of the dam structure to accommodate the area of the sprayed pile, The water level of the seawater is set to be higher than that of the seawater at the time of high temperature (rush), and it is possible to prevent the pirate creatures from intruding into the space inside the pirate biological intrusion barrier at high tide.

It is appropriate that the lower part of the pirate biological intrusion barrier is pushed deep into the tidal flats in order to block the space connected to the outside so that the pirate biological material intruded on the support can not penetrate by the inside spraying paper.

The spatula sprayed in the artificial spatula spraying step is sprayed in an amount of 10,000 per square meter on the spatula formed by the method of the present invention as a 1-2 mm artificial spatula passing through a deposition step in a terrestrial water tank. In the spraying step of the present invention, the depth of the sprayed paper is maintained at a minimum of 20 to 30 cm, and the spraying period is performed at a low temperature.

Fig. 6 shows a sampling method of the seedling harvesting step in the method of intermediate cultivation of a gourd shellfish artificial seedling using the tidal flats of the present invention. The seedling harvesting step is a step of harvesting the seedlings that have undergone the intermediate growing step in the above spraying pans, from the spraying papers of the present invention in order to feed them into the seedling or to grow them.

It is appropriate that the sparrow harvested from the sparge is grown to 1-2 cm in size after about 2 months of intermediate growth, and the shell of the sparrow shell to be harvested is so weak that it can be harvested by using harvesting equipment, Therefore, the sampling method of the present invention should be used.

In the sampling method of the present invention, a dam is installed at the upper part of the infiltration site of the goryeo-zoster goby so as to block the breathing water, and when the goryo-zushi goby moves to the upper part of the dam for respiration, it can be easily collected by removing the accumulated dam.

The harvesting method of the present invention utilizes the habitat characteristics of the garlic clam. As shown in FIG. 6, the garlic clam grown at 1-2 cm penetrates deeply through two breathing holes of the water catching ball and the absorption ball, If you build a dam and block the breathing, you can move the shellfish to the upper level for breathing and remove the accumulated dam to collect the shellfish.

FIG. 7 is a graph showing the change in survival rate of artificial tarsus in a general tidal flat and an intermediate tidal flat in the method of cultivating an artificial nursery using the tidal flats of the present invention. In the case of the garlic clam that has been subjected to the intermediate cultivation step through the method of the present invention, the survival rate of the garlic raised by the conventional method is less than 30% after one month, , The survival rate of the sparrows fed with the method of the present invention was slightly decreased after 2 months, but there was no significant difference compared with the survival rate of 1 month On the other hand, the survival rate of the garlic mackerel sprouts which had been cultivated by the conventional method was close to 0%, and the method of intermediate sprouting of the garnet molluscs of the present invention was found to have an effect of increasing the initial survival rate of sprouts.

It is difficult to obtain nursery seedlings naturally due to soil reclamation, coastal landfill and development, marine environment change, aquaculture fishery pollution, and the like, and artificial nursery production is possible in recent years in the supply market of garlic mash. However, In order to increase the survival rate and increase the growth rate during the intermediate cultivation stage, which is the cause of the wastage rate, and to secure the export volume of the Goryo Ryoko Shell, which has a large export portion, have.
