Description

Building method of seagrass habitat using poisoning {Build up method of Seagrass habitat using Doksal}

The present invention relates to a method for forming a zalpi habitat using poisoning, and more particularly, to a method for preparing a zalpi habitat, which is a natural friendly seaweed colony using poisoning which is an old fishing method.

In general, poisonous poisoning is a traditional fishing method in which tidal waters pile up stones along the coast, and when the tide becomes high, the fish come together with the sea water. Since it is built of stone, it is called 'Sukbangmyeon' in Chinese characters, in addition to 'poison' in the west coast, it is also called 'dokjang' or 'sugidam' and in Jeju island 'wondam'.

Poisonous poisonous fish are trapped in a stone wall and cannot be escaped at low tide and remain in shallow water, and they are caught by fishing nets (foot pants). The location of poison poison is usually suitable for coastal terrain and small islands in close distances. The slope is gentle and there should be a little water remaining in the stone wall at low tide. The stone wall is usually about 100m long and 300m large. There is also me.

At this time, the stone wall is piled up with three lines of large stones and the width becomes narrower as the upper part gets smaller, and the small stones are piled up. . In addition, the poisonous stone wall has an oval or 'a' shape, and has a slightly deep puddle to collect fish in the middle part, and in some places, a 'tubing box' is installed to allow the fish to enter. On the other hand, it takes a lot of labor to build a stone wall, and after completion, it is necessary to repair the torn down spots two or three times a year. The fishing is very simple because you go to a fishing place, take a stone wall, go to a pool, and collect the fish that are gathered in a basket.

In the past, poisoning has been useful for catching fish due to the abundance of fish species and has been activated a lot because of this, but in recent years, fish have not been caught, and due to many difficulties in maintenance management, they have been gradually affected by marine pollution. It is damaged and is now almost lost. Currently, only part of Jeju Island and Taean Peninsula are maintained.

Seagrass, a type of seaweed, is a seaweed that lives in the marine environment. It is a flowering plant that has well developed leaves, Rhizome, and vascular bundle tissues, which bloom and fertilize to form fruit. Collectively. 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 vegetation formed by sexually reproductive breeding are continuously maintained, and this species is known to have distributed about 60 species of 5 and 13 genera worldwide. 9 species of 2 and 4 genera are known. At present, it is an indispensable place in the estuary and coastal ecosystem, including leeches and babies that grow wild on the coast of Korea. Zalpi (seaweed) is a plant with excellent photosynthesis, has a very high productivity, and has a close relationship with coastal fisheries as the organics produced are incorporated into higher levels of nutrition.

And leaves of seagrass can be decomposed 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.

However, the destruction of habitats that can grow well by fishermen's densely growing farms and the uncontrolled discharge of uncleaned wastewater and factories, resulting in increased wastewater and coastal pollution from the estuaries, Zalpi disappears due to insufficient photosynthetic action due to turbidity, and as a result, it is disappearing as Zalpi and colonies are not brought to attention because of economic reasons.

Therefore, to solve these problems, an object of the present invention is not only to have a natural purification function by using the old fish poisoning method of poisoning, but also to have the function of the spawning ground and nursery ground of marine life growth It is to provide a way to create a nature-friendly zalpy habitat where people can experience and experience marine ecosystems such as fish and shellfish.

In particular, the present invention can secure a suitable amount of light for the growth environment of the zalpi, reduce the flow velocity of the waves flocking to the shore to reduce the stress of the zalpi to reduce the stress of the zalpi habitat development method using a poisonous poison using poisoning In providing.

With reference to the accompanying drawings, a method for forming a well-preserved habitat using poisoning according to the present invention will be understood by the embodiments described in detail below.

1 and 2, the poisoning 10 is used for the composition of the halal habitat (1) using the poisoning according to the present invention.

At this time, the algae habitat (1) is adjacent to the inner bay (2), but there is a difference between tidal, but the flow of seawater flows in a constant direction, selects a place where turbidity is relatively stable. In addition, from the environmental aspects of water quality, the summer water temperature should be more than 30 ℃ area, low quality journey is sand-sarinsil, high COD and petroleum high area is suitable.

In addition, when the poison 10 is dried, the amount of insolation, the amount of light in the water, the seabed topography, water temperature, salinity, tide, algae, poor particle size, harmful substances, etc. should also be considered.

On the other hand, poisoning 10 may be used as it is previously installed in the coastal area or installed on the coast having a suitable terrain. In particular, by using the difference between the tide and tide, which is a characteristic of the west coast, poison poison (10) is made and zalpi (F) is implanted inside and outside poison poisoning.

Such a zalpi habitat (1) is to choose a relatively stable bay (bay) or beach (2) to make poison (10) and transplant the zalpi (F), at this time should be able to increase the amount of light due to the nature of the zalpi (F) do. In addition, the poison 10 reduces the flow velocity of the waves rushing to the coast, as well as the inside of the poison 10 is a low quality layer 20 mixed with the sani quality and nizil in a certain ratio to facilitate the transplantation and formatting of the jaal. Form to a certain thickness.

On the other hand, the low quality layer 20 is implanted in the well (F) not only to have a natural purification function, but also to function as a spawning and nursery of marine life.

In this case, it is also possible to directly implant the swelling (F) into the reservoir layer 20, but since it may be lost during the high tide or low tide, it is shown in Figure 4a to 4c to support the swelling (F) to prevent loss Implant network 30 as described above is used.

At this time, the implanted network 30 has a plurality of fixed spaces 31 having a horizontal powder 32 formed with a plurality of horizontal rods 32a at regular intervals and a vertical powder 34 having a plurality of vertical rods 34a formed at a predetermined interval. It is made by cross-linking to form a), the graft network 30 is supported by the support pin 33 is inserted through the fixing space 31 to be fixed to the reservoir layer 20.

In more detail, the horizontal powder 32 and the vertical powder 34 may be cross-coupled to form a plurality of fixed spaces 31. In particular, the horizontal spacing 32a and the vertical rod 34a may be formed at intervals. By adjusting the size of the fixed space 31 into which the stem or root of the jaalpy (F) can be inserted and fixed, it can be used regardless of the stem and the root region having different thicknesses or sizes depending on the type of the jaalpy (F). .

At this time, as shown in (a) of FIG. 5, when the horizontal powder 32 and the vertical powder 34 simply cross each other, they are bundled and fastened by a fastening means 35 such as a wire or a rope. Of course, as shown in Figure 5 (b) it is also possible to cross-couple the horizontal bar (32a) and the vertical bar (34a) in the form of a grid. In this case, the horizontal powder 32 and the vertical powder 34 are preferably made of a metal material having a light weight and elasticity.

On the other hand, the support pin 33 is composed of a leg (33a) which is inserted through each of the two adjacent fixed space 31 and the engaging portion (33b) provided on the upper end of the leg (33a), the horizontal powder ( 32) and the fine powder 34 are cross-linked to fix the jalpy (F) in the fixed space 31, when the leg 33a is inserted into two adjacent fixing space 31 when fixing to the reservoir layer 20. After fixed bonding to the reservoir layer 20.

Hereinafter, a detailed description will be given of a composition process of a zalpi habitat using poisoning according to the present invention.

First, the poison wall 10 is dried by stacking the stone wall 11 to a height of 2 to 3 m so that a constant accommodation space 3 is formed. In this case, the inner accommodating space 3 of the poison 10 may be designed to have various areas, but it is preferable to stack a stone wall to have an area of about 1 ha (ha).

At this time, the stone wall 11 has a lower width is wider, as the upper portion is formed to be narrower.

In addition, when the stone wall (11) is stacked to form a gap by using a natural stone of a predetermined size or more to allow the seawater to smoothly flow through the gap.

After drying the poison 11 as described above, the inclined surface (3a) having an inclination (θ °) of 20 to 50 ° inward to the edge of the receiving space (3) formed inside the stone wall (11) Formed to ensure the maximum amount of light as possible, preferably to be constructed to achieve 45 °.

On the other hand, while maintaining a constant interval with the poisoning 10 and further forms a stone wall for reducing the flow rate (12). Such a flow rate reducing stone wall 12 is particularly installed to prevent the loss of poison 10 caused by the rapid algae flowing in the tide or ebb tide, it is preferable that the flow of algae is installed on the relatively strong side.

In addition, the low quality layer 20 is formed in the accommodation space 3 formed by forming the poison 10. At this time, the low-quality layer 20 is mixed with sanisil and nizil in a weight ratio of 4: 6 to 6: 4 to form a thickness of 30 ~ 60cm to facilitate the implantation and formatting of the jalpi (F). Of course, the low quality layer 20 is preferably formed to a thickness of 50cm by mixing the sani and nizil in a weight ratio of 5: 5.

Such a low quality layer 20 is easy to drain and prevents the accumulation of seawater.

And the jealpi (F) is implanted in the reservoir layer 20. At this time, in the case of simply implanting the swelling (F) in order to minimize the loss of the swelling (F) due to the difference between the tidal tide of the implant network 30 is fixed to the upper part of the reservoir layer 20 Install on.

At this time, after placing a jalpi (F) that grows over a certain size in the ground at a predetermined interval on the horizontal rod (32a) formed in the horizontal powder 32 constituting the graft network 30, the vertical powder 34 to the horizontal powder ( 32). Particularly, the horizontal bar 32A and vertical bar 34a are cross-coupled with the horizontal bar 32a and the vertical bar 34a to be fixed by the horizontal bar 32a and the vertical bar 34a, and the horizontal bar until the horizontal bar is fixed. The assembly 32 is completed by bringing the 32a and the vertical rod 34a into close contact with each other.

The implanted net 30 in the state of fixing the jaalpy (F) can be simply installed in the reservoir layer 20 in the accommodation space 3, but the support pins 33 to prevent loss due to the swept by the algae ) To the lower layer (0).

As described above, when implanting jalpi (F) using the transplant network 30, the zalpi (F) is stably settled in the medulla layer 20 after 2 to 3 months, and then isolates the transplant network (30).

Of course, when the implanted network 30 is separated, the dropping of the well, such as monitoring the drop off of the well (F) to transplant the well portion is preferably transplanted well.

6 is a view showing another embodiment of the present invention, before forming the low quality layer 20 on the upper side of the inner bottom layer 4 of the accommodation space 3 formed by forming the poison 10. A shell layer 40 having a predetermined thickness (for example, 5 to 20 cm) is formed. Therefore, due to the shell layer 40 formed between the inner bottom layer 4 and the low quality layer 20, the drainage of seawater is made better.

The shell layer 40 as described above uses shells such as oyster shells or shells.

As described above, embodiments of the present invention have been described in detail, but the scope of the present invention is not limited thereto, and the scope of the present invention extends to the range substantially equivalent to the embodiments of the present invention.
