Description

Development method of shellfish farm using algae nursery {development method of shellfish farm using Seagrass nursery}

The present invention relates to a shellfish farm composition method using the seagrass nursery, more specifically, the clam (Ruditapes To improve the productivity of shellfish (shellfish) such as hilippinarum ) , the shellfish is used to create a zallar nursery around the shellfish farm, which improves the quality and quality of the shellfish, and transplants them into a fence around the shellfish farm. It is about a method of farming.

In the west coast area, environmental pollution caused by large-scale land reclamation, construction of new towns, urban expansion and industrialization of the metropolitan area is intensifying, and fisheries are scattered and habitats are damaged and fishery resources are drastically reduced. If overfishing and environmental pollution persist, In addition to the devastation of fishermen, it is highly likely that the fishing village will enter into a difficult state to recover.

In addition, the production of clam aquaculture, the most important aquaculture on the west coast of tidal flats, peaked at 53,648 tonnes in 1992, and then declined sharply to 7,703 tonnes in 1997 and stabilized at 27,905 tonnes in 2009.

The decline in clam production is known to be due to the large-scale reclamation and the reduction of shellfish farms due to reclamation projects, pollution of farmed fish farms, and mass deaths due to climate change.

On the other hand, although it is necessary to secure a farming site for artificial farming of shellfish such as clams and donjuk, in farming areas where there is a high flow rate due to the tidal wave difference, even if the seed is scattered, it is difficult to farm. In addition to considering environmental factors in securing the site, it is necessary to provide enough nutrients such as organic matter to produce high quality shellfish.

Therefore, shellfish farms need to consider a variety of environments and conditions, such as water quality, so it is difficult to select a location, so shellfish can be farmed only in limited areas.

Therefore, the present invention is a technology supported by the 2011 Ministry of Land, Transport and Maritime Affairs Sea Grant project in order to solve the above problems, to create a well-being nursery nursery to improve the water quality and low quality around shellfish farms such as clams and donjuk The purpose of this is to provide a method for forming a shellfish farm to produce high quality shellfish with high productivity in the shellfish farm by forming a wall along the edge of the shellfish farm.

In addition, the present invention is to reduce the algae (flow) and flow rate around the farm, to suppress the inflow and loss of external low quality, improve the water quality environment to increase the self-cleaning capacity of the tidal flats to increase the quality of shellfish farms The aim is to provide a way to create shellfish farms that are advantageous for the selection of fisheries.

The present invention to solve this technical problem;

A first step of forming jaalpi nursery around the shellfish farm; And a second step of implanting the algae of the algae nursery along the edge of the shellfish farm to form the alveolar wall. Provides a method for the composition of shellfish farms using the Jalpy nursery, characterized in that consisting of.

At this time, the zalpi nursery is characterized in that it is formed in the form of a chessboard alternately forming a well-known implanted gypsum and gypsum transplanted around the shellfish farm.

In addition, the jalpy fence is characterized in that it is formed in the form of a chessboard alternately forming a well-known transplanted jalpy transplants and jalpy transplanted along the edge of the shellfish farm.

At this time, the zalpi graft paper of the zalypian wall is characterized in that to transplant 20 to 30 of the zalpi per unit area (㎡).

And the zalpi nursery alternately create a well-known implanted galphal transplant paper and a well-known non-algae graft; The zalpi nursery is characterized in that the composition on the scale of 1/100 of the shellfish farm area.

At this time, the ginseng transplanted paper of the zalypium nursery is characterized in that 20 to 30 of the gals are implanted per unit area (㎡).

On the other hand, in the second step, the zalpi fence is characterized in that it is formed by transplanting the zalpi along the edge of the shellfish farm after the 3 to 4 months to form the seedling nursery.

According to the present invention, the algae nursery is installed around shellfish farms such as clams, donjuk or komak, and the alveolars of the nursery are transplanted along the edges of the farms to form the algal pads and the algae by the algae implanted at the edge of the farms. It can reduce the flow rate and increase the self-cleaning ability of mud flats, improve the quality of shellfish farms, and improve the growth and reproduction of clams. It has the effect of increasing the quality of clam productivity.

Figure 3 is an enlarged view showing the walrus fence formed along the edge of the shellfish farm according to the present invention.
Figure 4 is a view showing various embodiments of the shellfish farm using the jealpi nursery in accordance with the present invention.

The characteristics of the shellfish nursery using the shellfish nursery according to the present invention will be understood by the embodiments described in detail below with reference to the accompanying drawings.

First, for the composition of the shellfish farm according to the present invention is used jalpy nursery. Seagrass (Seagrass), a type of seaweed, is a seagrass that lives in the marine environment. It is a flowering plant that develops leaves, underground diameters, and vascular bundles, and develops flowers by forming flowers. Collectively the plant. Algae, on the other hand, survive by attaching to rocks or other substrates through attachments.

In addition, it is known that the germination and seeding of the seeds formed through sexual reproduction in the continually maintained seagrasses. Such stalks are known to have distributed about 60 species of 5 and 13 genera worldwide. It is known that 9 species of 2 and 4 genera are distributed.

Among the seaweeds native to Korea's coast, halves and baby heads are indispensable in the estuary and coastal ecosystems. The seaweed is a plant with excellent photosynthesis and has very high productivity and produced organic matter. As it enters this upper trophic level, the habitat of zalfi is closely linked to coastal fisheries productivity.

And leaves of seagrass can be removed after absorbing quickly a number of pollutants such as nitrogen and phosphorus are introduced into the river mouth, there is also effect of reducing the carbon dioxide (CO _2), to absorb the carbon dioxide (CO ₂₎ main cause of global warming, In addition, the ability to produce oxygen (O ₂ ) is very excellent, showing an effect on water purification.

In addition, Zalpi's underground diameters and root tissues have a natural purification function that stabilizes sediments and absorbs and removes contaminants such as heavy metals in the sediments. In addition, Zalpi habitats are used as spawning grounds and nurseries for marine organisms. Has information on diversity and coastal environment. The proper growth condition of the jaalpies requires an annual average of 3E · m ⁻² · day ⁻¹ or more, and the average water temperature in August is 28 ℃ or less, salinity 17 ~ 34psu, oil wave height 0.5m or less, bottom surface flow rate 0.6m / s or less. Must be maintained.

In particular, seagrass, a marine flowering plant, has an ecosystem purification ability to absorb and remove inorganic nutrients and pollutants that are excessively introduced into coastal areas. Calculating this cleansing capacity of zalfi as a habitat for algae can purify 260 tonnes of 10 µm DIN seawater. In addition, algae leaves slow down algae to sink suspended particles in seawater, while dense underground diameters and root tissues stabilize the soil in the sea, purifying seawater.

In addition, the protection of the marine ecosystem is protected by the Act on the Conservation and Management of Marine Ecosystems.However, it is difficult to secure the seedlings when transplanting. It can be prevented, and can be easily used in case of damage of natural pavement due to natural phenomenon such as coastal development project or typhoon.

According to Figures 1 to 3 shellfish farms 100 using the jaalpy nursery in accordance with the present invention is for farming shellfish, such as clam or dongjuk, the shellfish nursery having a water quality and low quality improvement around the shellfish farm 100 ( After the 200) to form the shells (1) implanted along the edge of the shellfish farm 100 to form a wall 300.

First, the present invention is to provide a jaalpy (1) for forming a jaalpy wall 300 along the edge of the shellfish farm 100 by installing the jaalery nursery 200 around the shellfish farm 100, such as clam or dongjuk Significantly, the jaalpy fence 300 is alternately altered with a well-known paper (320) transplanted without the transplanted jalpi (310) and zalpi (1) transplanted along the edge of the shellfish farm (100). Form and form in the form of chessboard. In this case, when the jalpy fence 300 is formed in the form of a chessboard, multiple rows may be formed, and preferably, 2 rows may be formed in the outer and outer sides of the public space 320 and the jalpy fence 300. Allow the scalp (1) to expand.

On the other hand, jalpy nursery 200 is preferably in the vicinity of the 10m ~ 500m distance from the shellfish farm 100 to facilitate transplantation.

In addition, the Zalpi nursery 200, for example, 1 ㎡ in 2 ㎡ is transplanted to the halpi graft paper 210 implanted with the swelling (1), 1 ㎡ adjacent to the swelling paper 210 to transplant the swelling (1) It is formed in the form of chessboard by alternating composition of the well-being paper 210 and the announcement in a manner to form a not known 220. In this case, the jalpy transplant paper 210 and the known 220 may be formed in various units within the range of 0.5 ~ 2㎡ square of the unit area according to the surrounding environment.

Of course, the jalpi fence 300 is a fence-like shape after transplanting the jalpi (1) of the zalpi nursery 200 to wrap along the edge of the shellfish farm 100, such as clam, dongjuk or kerchief in the form of a fence naturally It induces growth, and consequently wraps the zalpi (1) along the edge of the farm.

On the other hand, it is preferable that the scale of the jaal nursery 200 is set to 1/100 of the area of the shellfish farm 100, for example. For example, when the shellfish farm 100 has an area of 1 mm, it is preferable that the seedling nursery 200 forms 0.01 mm 3.

At this time, when forming the zalypium nursery 200 in the vicinity of the shellfish farm 100, 20 to 30 per unit area (㎡), 20 to 30 per unit area (m 2), preferably 25 objects / ㎡ Transplanted and managed to maintain the number of Zalpi populations in the same range as the Zalpi nursery.

In addition, after forming the jalpi fence 300 along the edge of the shellfish farm 100 to manage the jalpi fence 300 and the nursery nursery 200 through the operation of periodically swelling the zalpi (1).

Clams like this ( Ruditapes The algae and the flow rate of the algae (1) by transplanting the algal (1) formed in the algae nursery (200) along the edge of the shellfish farm (100 ) such as hilippinarum) In addition, it is effective in reducing external inflow and loss, improving water quality, and improving the self-cleaning ability of tidal flats, improving the quality characteristics of shellfish farm 100, and affecting the growth and reproduction of clam, etc. High quality shellfish productivity can be increased.

On the other hand, when transplanting the jalpy (1) to form a jalpy fence 300 around the shellfish farm (100), when transplanting too many jalpy (1) objects per unit area when the zalpy (1) objects collide with each other, the adult may be damaged And, jalpi (1) during the growth of the underground diameter (地下 莖) to prevent the expansion of, and if the individual density high species competition occurs. Therefore, in view of these points, it is important to transplant from the early stage through the scientific method of transplanting jaalpi.

In particular, Xalpi (1) is a species that must be protected according to Article 20 of the Act on the Conservation and Management of Marine Ecosystem (Prohibition of Capture, Collection, etc. of Protected Organisms). It is difficult to secure the target species for transplantation.

In addition, when collecting and transplanting Zalpi (1) from other regions, ecological disturbances should be considered, cooperation and cooperation of each fishing village is required, and the quality, repair, and other environment to which Zalpi (1) can be transplanted should be considered.

Therefore, in order to comprehensively establish local conditions and shellfish farms (100) such as clams, close cooperation with neighboring fishing villages should be preceded, and the overall situation of the marine environment can be scientifically based on the basic survey considered during transplantation. You must approach.

Hereinafter, a description will be given of a preferred embodiment of the shellfish farming process using the jaalpy nursery according to the present invention.

First, the clam ( Ruditapes In order to improve the productivity of shellfish farm 100 , such as hilippinarum ) , the seagrass nursery 200 having an effect of improving water quality and water quality is formed around the shellfish farm 100, and then the bleeding along the edges of the shellfish farm 100 is performed. 25 objects / m 2 are implanted to form or form the palpital fence 300.

In particular, after the shelling nursery 200 is formed around the shellfish farm 100 and it takes about 3 to 4 months, 25 shellfish (1) per unit area (m 2) are formed along the edge of the shellfish farm 100. Implants form a well-finished fence (300). In this case, implanting too many objects per unit area when transplanting jalpi (1) may collide with the objects between the zalpi (1) and the adult may be damaged, preventing the extension of the underground diameter during the growth of the jalpi (1), individual density If high, species competition occurs, it is important to transplant the Jalpi considering these points.

Considering these points, the shellfish farming process is explained in detail.

After investigating the water quality and water environment around the shellfish farm 100, such as clam, dongjuk or kokcho, after selecting the zalpi nursery 200 and the halpi transplant site to be transplanted to the jaali nursery 200, the scallop nursery (200) 1) transplant.

At this time, in order to ensure the survival of the zalpi nursery 200 in the formulation of the zalpi nursery 200 implanted in the form of chessboard (25 objects / ㎡), the composition period is formed for 3 to 4 months in the spring or autumn. In this case, the zalpy nursery 200 is alternately alternately to form a chessboard in which the well-known implanted paper (210) implanted with the jaalpy (1) and the well-known (220) without the implanted (1). By forming in the form of such a chessboard jalpi (1) of the zalpi transplant paper 210 is a basement of the zalpi (1) extends toward the public notice 220, the growth of the zalpi is not disturbed to grow.

On the other hand, the jaalpi (1) of the composition of the jaalae nursery 200 is implanted along the edge of the shellfish farm 100 to form a wall 300. In this case, for example, 1 m 2 is alternately used as a gallery transplant paper 310 implanted with zalpi (1), and 1 m 2 adjacent to the zalpi graft paper 310 is known as 320 without transplanting the zalpi (1). By staggering composition to form a multi-row in the form of a chessboard, preferably formed in two rows.

In particular, through the management of the transplanted walrus (1) to ensure that the walrus (1) is expanded to the shellfish farm (100), and control the density control of the walrus (1) growing in the walrus nursery (200) and walrus wall (300) It is desirable to replant the algae (1) in the overdense area to the partly dead zone and the scarce part.
