Description

Oyster rack culture system, producing of nonattached individual seeds and methods of harvesting}

The present invention relates to a virtual set type oyster farming structure and a method for producing Hangul oyster seed paddle, and more specifically, seeding or natural seeding technique produced by artificial seedlings in a high-quality seed without omnivorous seedlings for seedlings Valued advanced oyster farming structure and this farming system that simplifies a series of farming processes and makes installation of farming structure simple and easy. The present invention relates to a method for producing and nurturing Hangul oyster seed required for a dragon structure.

Today our country tends to recognize tidal flats as land without owners, but in fact, tidal flats are one of the most important ecosystems of the Korean peninsula. The tidal flat ecosystem is a transitional zone where the ocean and land meet, where marine life is more dominant. As natural seedling is used not only as a seedling production site for shellfish and other fisheries but also as a high productivity farm, the use and imposition of these spaces is the oyster virtual farming method and various shellfish through this farming technique. It is also an area rich in useful marine life resources.

Among these aquatic biological resources, various aquaculture methods are used, especially in the case of oysters, and there are some differences in aquaculture methods according to the differences between tidal tides depending on the region and the characteristics of the marine environment. Looking at it as follows.

First, one of the oldest methods of conventional farming is the bottom farming, also known as dialysis farming, and it produces oysters from the bottom of the sea between tidal ships and several meters deep. Seeds are grown until the harvest is harvested.

In this dialysis type positive method, as shown in FIG. 1, a stone 103 or a shell used as an attachment substrate is injected into the seabed 105 so that the plaques 101 are attached to the injected stone 103 at an appropriate time. That's how it's done. By the way, this training method may be buried or lost due to the wind wave, etc., it is difficult to purchase the stone material, and the weight of the stone is heavy, there is a problem in transportation and facilities. In addition, considering the labor force and economic aspects of having to transfer and re-dialysis every year, it is not economical and is not preferable as an aquaculture method.

As shown in FIG. 2, the multi-bend training system maintains a plurality of knits 201 at regular intervals, inserts them into the anchor string 203, and then anchors 205 connected to both ends of the anchor string 203 to the seabed 207. Plugged in and fixed, and hanging from the mother line 204 floating in parallel with the sea surface yeonha yeon 209 at appropriate intervals to cultivate a seed plaque 211 attached to the yeonhayeon 209. At this time, the anchor line 203 is for the maintenance and fixing of the facility.

By the way, this method of cultivating the continuous drop type floats the moxa 201 made of plastic on the surface of the sea, connects it with a rope, fixes both ends of the rope with an anchor, and hangs a hanging rope on the rope to form a large amount. There was a problem that it is difficult to attach the seed pad to one hanger 209, which requires labor-intensive work for mass production.

The method shown in Figure 3 is a raft drop method, a plurality of transverse 301 and 303 between the rafts made by intersecting at appropriate intervals attached to the float 307 to give a buoyancy to float on the sea surface, After suspending a plurality of drooping edges 309 in the transverse direction between the transverse 301 and the longitudinal edge 303, a shell 311 is connected to each dredge 309, and a seed pad is attached to the shell 311. It is a positive way to cultivate.

Since the catamaran drooping method uses the raft 305 connected in two dimensions as a floating body, it is not suitable for use in a training field with frequent wind waves because it has a low wave resistance, and because of the buoyancy, the length of the droop 309 may be extended. The yield of oysters produced by one dredge 309 can be increased, so the yield for the labor input is relatively higher than that of the drowning method, but the seed is still attached to the dredge 309 one by one. There was a problem that required labor intensive work.

As such, the long-haul farming method is currently the main producer of aquaculture production because of the shortcomings of labor and breakwater resistance of the raft, because both productivity and economic efficiency are superior to the raft farming method. In addition, because of the strong strength to withstand the wave, long water can be used even in places where the waves are severely affected, such as inner bays or inland seas, which are heavily influenced by the open sea. However, if it is far from the coast, the amount of food organisms is reduced, so the growth may be slightly reduced.

The raft and long-haul method is a farming method currently used mainly on the coast of Gyeongnam, which is a serious problem every year because the environment is deteriorated due to the long-term accumulation of various wastes and excrement according to the long-term use of fisheries in the water. As a result, there are many problems such as reduced yield, frequent disease, and sluggish growth.

In addition, conventionally, the following natural harvesting techniques or artificial harvesting techniques have been used to produce seed for use in aquaculture, which will be described in more detail as follows.

First, the oyster's natural harvesting technique, when the water temperature rising in the spring and summer reaches a suitable spawning temperature of 25 to 30 ℃ two weeks after the egg is released into the seawater usually grows eyes or legs and grow into mature larvae. This is a method that is to be attached to the attaching machine in order to fit the time of dense scattering well to put in the picking machine 401 shown in FIG. At this time, the plunger 401 is made up of the chaebolsa 403 and the oyster shell 405 suspended in close contact with the chaemulsa 403, as shown in Figure 4, this chaejo 401 Hanging down on the item 409 of the seedling facility 407 as shown in 5, the oyster seed 411 is drawn on the surface of the oyster shell 405.

Therefore, when the seedlings are grown using a seedling, the oyster shells 405 are grown in a state in which they do not fall one by one. 405) is required a lot because there is a problem that the production efficiency is lowered due to transportation costs and material costs or labor force increase.

The artificial cultivation method, which has been recently developed as another cultivation method, manages oyster shells in a building such as an indoor tank to induce maturity, and then artificially induce spawning through temperature stimulation by temperature control. Raise larvae by feeding artificial feeds or keeping the environment appropriate. Then, the rearing larvae are attached to the oyster shell shown in FIG.

However, since artificial cultivation techniques are farmed in a limited space, the nutrition of oysters is poor, and the quality of oysters is relatively lower than that produced by natural cultivation, and requires various artificial operations required for breeding. As a result, the burden of labor and material costs increases, resulting in a drop in production efficiency.

Therefore, the present invention was devised to solve the problems of the conventional oyster farming method as mentioned above, and put one seed oyster seed in the sack called seed net and cultivation net produced separately during the training process It enables the production of success without a substrate, which greatly reduces the facility cost compared to the structure used in the conventional oyster farming method, greatly improves the productivity by reducing the number of work and mechanization of the work, and the structure has excellent breakwater resistance and field installation The purpose is to provide a simple and easy aquaculture structure and aquaculture methods.

In addition, the present invention is to solve the problems of the conventional seeding method, to cultivate the seeding method and the seeded seedlings to be seeded so that the seed can be separated and produced one by one in the form of a oyster by different materials used for seeding Another purpose is to provide a way to do this.

Here, the charging network (3) is a net made of PE-based Spencer to accommodate Hana oyster seed produced by artificial seedlings or Hana oyster seeded by natural harvesting techniques, and is shown in FIG. The first slave network 3-1 shown in FIG. 8 is divided into the second slave network 3-2 shown in FIG. 8 and the successful network 3-3 shown in FIG. Each charging network 3 has a diagonal length of 5 mm as shown in FIG. 7 for the longitudinal network 3-1 and B for the longitudinal mesh 3-2 of FIG. As shown, 9 mm, the successor net 3-3 of FIG. 9 has a length of 13 mm as indicated by C, and the first longitudinal net 3-1 is horizontal, i.e. 45 cm wide and long. 1100cm and 15cm in height, the second longitudinal net 3-2 is 60cm in width, 1100cm in length and 25cm in height, and finally the net 3-3 in length. Silver has a width of 75 cm, a length of 1100 cm, and a height of 30 cm.

As such, the different sizes of the charging network 3 accommodates the artificial seed or natural seed separated one by one, and only the pure seed is loaded in the charging network 3 without attachment substrate so that the seed is discharged from the charging network 3 according to the size. It is to prevent that. In addition, as the seed grows, the size of the net is gradually adjusted to give the physiological stability of the oysters in the net, to maintain the smooth communication of the seawater in the net and to protect the seed from other sea creatures.

The frame 9, which is intended to place these charging nets 3, is capable of being assembled and disassembled so that the loading nets 3 can be placed on the upper plate, and have legs 7 supporting the upper plate. If it is a structure, it can fully use, and it is preferable that it is comprised by the several support rod 5, 5 'connected so that a top board may orthogonally cross a longitudinal direction as shown to FIG. 6 and FIG.

Such a frame body 9 may be composed of a support column 11 shown in FIGS. 10 and 11 and a bench 13 coupled to the support column 11 as one embodiment of the present invention. At this time, the support column 11 is arranged in parallel with a plurality of predetermined intervals, the middle portion that serves as a transverse support rod (5 ') for supporting the base 13 and downward from both ends of the support rod (5'). There are two bent portions extending to form an appropriate angle to serve as the leg portion 7. The bent portion, that is, the end portion of the leg portion 7 extends upward at a short angle, for example, an angle of 50 °. The landing part 23 is formed. The cultured structure 1 is preferably 270 cm long, 130 cm wide, and 60 cm high.

In addition, although not shown separately, the base 13 is arranged in parallel at regular intervals in a direction orthogonal to the upper end of the supporting column 11 to serve as a longitudinal support rod 5 as a rod having a shape such as an elongated rebar. The base column 11 and the base 13 may use any material as long as the material has rigidity such as rebar. At this time, the support column 11 is 1.9 cm in diameter, the length of the transverse support rod 5 'is 100 cm, the distance between the two landing portions 23 is 160 cm, the height is 60 cm. Moreover, the base 13 is 1.6 cm in diameter, one length is 270 cm, four are 1.6 cm in diameter, and 270 cm in length.

When the supporting column 11 and the base 13 are fixed, as shown in FIG. 10, the intersection points are fixed by means of welding or the like in a state where a plurality of the columns are arranged to be orthogonal to each other, thereby placing the charging network 3 thereon. It is also possible to form a frame (9), removable considering the ease of installation or use in the removable point so as to separate the support column (11) and the base (13) by fixing the intersection point by a separate fastening means It is more preferable to form the frame 9.

It is composed of a plurality of detachable support column 11 and the base 13 to be assembled by the removable bracket 14, the frame 9, which is to put the charging net (3) of the structure (1) This is to make installation and movement very easy.

The fastening means can be used as a member capable of simultaneously joining a plurality of bases 11 and a plurality of bases 13 positioned to be orthogonal to the upper ends of the bases 11 in an assembled state. Preferably, for example, the bracket 14 shown in more detail in FIGS. 10 and 12 can be used.

This bracket 14 is composed of a horizontal barrel (17) fitted to the outer circumferential surface of the base 13 and a vertical barrel (21) fitted on the outer circumferential surface of the support column 11, as shown, The opening part 15 is cut in the lower part so that it may be fitted to the side of the base 13 which is located relatively upward in the state in which the base 13 was mounted on (11), while the vertical cylinder 21 is relatively lower in the lower side An opening 19 is formed at the bottom to be fitted to the supporting column 11, which is positioned at a lower part, and is detached in two stages so as not to cause interference with the base 13, and is attached at right angles to the side surface of the lower surface of the cross barrel 17. It is.

At this time, the fixed horse 22 as shown in Figure 13 to the landing part 23 formed on the lower end of the leg portion 7 of the supporting column 11 and plugged into the bottom of the tiling ground lightly just installed in the tiling ground The frame body 9 is prevented from being overturned due to algae or the like. At this time, the diameter of the fixed end 22 is 0.6 cm, the length is 100 cm.

The cultured structure 1 of the present invention configured as described above, as shown in FIG. 14, is configured to constitute a single cultured structure unit set 50 by three support columns 11 and four hangers 13. In addition, the unit set 50 is arranged so as to be two rows and five rows in the same direction as the flow direction of the algae so as to receive less resistance by the algae, such an arrangement forms a farming unit group 60.

At this time, the unit group 60 may also be installed at any position of the tidal flat, each set of units 50 is maintained in the horizontal direction 1m intervals to secure the movement path of the worker between each, Between the unit groups 60, the interval of 7m in the lateral direction is maintained in order to secure the moving path of the transport vehicle or the work vehicle.

In addition, in order to cultivate seed by the cultured structure 1 of the present invention, seed seed is obtained through the following seeding facility and the seeding process, but first, the seeding facility 500 as shown in FIG. 15 is used.

As shown in the drawing equipment 500, a plurality of horse holding 501, a plurality of twisted yarns 503 and PP band 505 tied to the holding horse. Here, the fixed horsewood 501 is to be driven in the state of maintaining a constant interval longitudinally and horizontally on the bottom of the tidal flat, and the twisted yarn 503 is arranged in the transverse direction while maintaining a height of 60 cm from the bottom of the tidal flat. Similarly, the PP band 505 arranged at right angles to the 503 is to maintain a height of 60 cm from the bottom. At this time, the PP band 505 is prevented from being twisted by the auxiliary rope.

In the case of seeding the seed by the seedling equipment 1 configured as described above, first install the above oyster seed seeding planting equipment 500 in the interstitial ground where the bottom surface is exposed for about 4 to 5 hours.

Then, when the seed is attached to the PP band 505 and the age of the seed reaches 30 to 50 days, the worker sweeps and harvests the seed 507 grown from the PP band 505 by hand. The seed cards collected in this way are immediately transferred to the aquaculture structure 1 by counting population by scale.

The Hangul oyster seed 507 collected by the individual is first put in the first seed net 3-1, placed on the aquaculture structure 1, strapped with a wire, etc. -2) If the training period expires and is transferred to the success net (3-3), the aquaculture operation ends.

As described above, according to the cultured structure of the present invention, since a loading network is used as the seed oyster seed acceptor, the seed seed can be directly accommodated in the loading network to omit the construction of the seedling carving angle, thereby simplifying the seedling work process, and cultivating seedlings. Since it is made in the charging network, not only can it reduce the damage caused by the pirates, but also it can be packaged with the successful success and failure for handling by transportation, etc.

In addition, it is possible to cultivate seedlings in a more hygienic environment, because it can be installed to maintain a certain height from the bottom surface of the charging net accommodated by the frame body, and the frame body is removable by using a removable bracket Since it can be assembled, it is easy to move and install the frame body, which can drastically reduce the working time or labor cost according to the equipment of the farmed structure.

In particular, it is possible to farm in intertidal zones such as the southwest coast, avoiding terrestrial fish farms, which are seriously polluted by the marine environment. Therefore, there is no need to worry about the aging of fisheries and the environmental pollution caused by long-term use of fish farms. Self-cleaning by using marine microorganisms of the fish makes it possible to produce oysters with excellent meat quality.

In addition, since the seedling seed is obtained by a separate seeding facility, the seedlings can be separated and collected more easily one by one.The equipment and materials required for seeding are reduced and the volume is small, so the material cost is reduced and the facility work is easy. This can lead to anger, and thus reduces labor input, resulting in more effective harvesting.

Therefore, according to the cultured structure and seeding facilities of the present invention and the resulting farming and seeding technique can be expected to spread the aquaculture industry in the intertidal zone, ultimately it is possible to create high value added by the competitive oyster farming industry.

While the invention has been shown and described with respect to particular embodiments, those skilled in the art will recognize that various modifications and changes can be made without departing from the spirit and scope of the invention as indicated by the appended claims. Anyone can easily know.
