Description

{A FISH REEF FOR ABALONE}

The present invention relates to the structure of an overturned reef which is advantageous for promoting the habitat and proliferation of abalone.

The Korean fisheries industry has entered the 2000s, and as a result of globalization and liberalization, imports of aquatic products have increased and domestic fishery prices have fallen and competitiveness has been shrinking. In order to actively cope with such international environmental changes, development of new fisheries technology is urgently required.

In general, the share of fishery production in total fishery products is stagnating or decreasing, but the production of fishery products is increasing. As a result, the share of fisheries production in fishery production has continuously increased year by year from 26.0% in 2000 to 42.3% in 2007. In particular, the production of shellfish aquaculture increased 2.15 times from 222,608 tons in 2000 to 478,646 tons in 2007. Among them, the abalone production is rapidly increasing from 20 tons in 2000 to 4,350 tons in 2007.

As a result, there is an urgent need to mass-produce industrialization by developing new high-density eco-friendly aquaculture industry with large potential for domestic and overseas markets. Especially abalone is an aquatic product with very high added value and it is necessary to develop abalone reefs suitable for the flow and low quality of the sea area to increase abalone production.

In the past, a number of sea turtle turtles have been developed for similar reasons. However, it is known that sea cucumbers and abalones are similar in habitat. Therefore, development of reptiles suitable for abalone habitation and propagation was relatively insignificant.

Previously developed sea cucumber fish catches are submerged with legs at the lower part of the reef. In order to prevent burial, the width of the legs becomes larger as they go downward. Distribute the support points far away to prevent the phenomenon that the reed is turned.

However, the above-mentioned bridge structure, due to the width of the legs increasing toward the lower part, interferes with the invasion of the lower part of the reed, so that the legs are not soaked so that the reed is turned over.

As a result, the space between the bottom of the sea bed and the bottom of the reef is kept too wide, and the space does not function as the original fish. The lift caused by the inflowing seawater frequently led to the reef.

Further, the legs of the shape widening outward have a factor that hinders the arrangement of a plurality of fish reefs in a dense arrangement.

There is a habit of locating abalone on cracks, rocks, rocks and rocks of underwater rocks, and concentrating mainly on specific areas of the sea floor. Abalone is a place where rhubarb and mangute are prosperous.

Abalone is generally known as herbivorous. Hatching larvae do not eat prey until the adherent period, and they swim in the sea water. After 4 ~ 5 days, they enter the benthos crawling period and eat microalgae. During the seedling production period, it grows up to 5mm ~ 6mm with feeding diatoms of adherent diatoms. From then on, it grows algae such as seaweed, parasites and so on. Abalone has different selectivity depending on the type of seaweed. Main food is seaweed, seaweed, mackerel and other brown algae. In addition, algae such as green algae and red algae are consumed. Copepods, sharks, and nematodes are detected in the abalone digestive system, but these microscopic organisms are considered to be a mixture of food intake. When cultured in the sea, live seaweeds such as seaweed, kelp, and coral reefs attached to the nearby area are supplied. When the seaweeds are difficult to supply, dried seaweeds and salted seaweeds can be supplied.

Abalone growth is closely related to food activity and water temperature, so under 7 ℃ usually eat less, and activity is very dull. In the case of feeding the seaweeds, the daily feeding rate was 7.5%, 14.7% and 17.6% at body temperature of 10.9 ℃, 16.5 ℃ and 20.3 ℃, respectively. The higher water temperature, the higher the feeding rate Monthly rate of increase was 12.8%, 27.0%, and 32.1%, respectively. The higher the water temperature, the higher the monthly increase rate. From these results, it can be said that the optimum growth temperature of abalone is about 15 ~ 20 ℃.

The growth of abalone differs depending on the region. In the spawning season and the low temperature season, the shell growth is temporarily stopped to form a ring. As a result of the investigation of the growth rate of the Korean abalone, it was found that it grows up to 7.5cm in length, but takes 5-7 years in the northern part, while it takes 4-6 years in the southern part to grow 11cm in length. Abalone where the habitat environment is good and where there is a lot of food, the shell is thin, the growth is rapid, and it grows big. However, in places where the environment is not good, there are many irregularities in the shell, not only thick but also slow growth.

Abalone growth varies seasonally, especially in relation to water temperature and food intake. When the spawning season is over, the amount of food is reduced, and when the spawning season is over, the appetite is increased, so the amount of food is increased, reaching the highest in spring, decreasing thereafter, becoming the lowest in summer and passing in autumn. The seasonal changes of the black abalone growth are rapid in December to May and almost cease to grow in July and September. The obesity period of the abalone is from February to July, and the obesity level at the time of spawning is lowered to the lowest in September and October. Therefore, the seasonal change of obesity index is a physiological factor due to mature scattering of gonads.

In the case of the abalone, about 200,000 eggs are obtained when a mature ovary is 1g. The number of eggs possessed by the abalone mother is generally estimated to be about 1 million when 8 to 9 cm of the cornice is in the shell, about 2 million when the corn is 9 to 10 cm, and about 3 million when the cornice is 10 cm or more. The amount of bounce varies greatly depending on the size and mature state. In the case of true abalone, the mean egg production is about 200,000 to 500,000 in 8cm size, and the average egg production is about 2 million in the size of 12cm in the abalone.

The eggs that are scattered are spherical, piled up in a thick agar quality, and are separated from each other. The size of the egg yolk is usually about 0.18 mm, and the size of the embryo including the ovary is slightly different depending on the type of abalone. The size of embryo for each type was 0.22mm in abalone, 0.23mm in abalone, 0.28mm in abalone, 0.27mm in abalone, 0.18mm to 0.2mm in eruption, and 0.4-0.5mm in thick agar Piled up. The spermatozoa have long hair and tail, and the tofu is 8 μm and the tail is about 50 μm.

The overturning reptile 1 of the present invention is designed based on the above-described wetting behavior. The overturning reed 1 includes a main body 10 and legs 80 provided at a lower portion of the main body 10.

<Body>

The overall shape of the main body 10 is the shape of the square truncated cone (a). The width of the lower end of the square truncated cone (a) is about twice the width of the upper end, and the inclination angle (b) of the truncated cone is in the range of 55 to 65 degrees. The width c of the lower end of the body disclosed in the embodiment of the present invention is 2.4 m, the height h is 1.0 m, and the inclination angle b is about 60 degrees. The shape of the truncated cone can increase the stability of the overturned reptile.

The main body 10 includes a plurality of roof members 20 vertically stacked. The vertical distance g between the roof members 21, 22, 23 and 24 can be set equal to the thickness t of the roof members 21, 22, 23 and 24. According to an embodiment of the present invention, the distance between the roof members may be 0.15 m, and the thickness of the roof member may also be 0.15 m.

The roof member 20 may also be in the shape of a square truncated cone. The roof member 20 has a square lower surface 201, a square upper surface 202 smaller than the lower surface 201 and a side surface 203 connecting the lower surface 201 and the upper surface 202 Respectively. The side inclination angle k formed by the side surface 203 with the lower surface 201 may be 35 degrees to 45 degrees. In the embodiment, a structure in which the side inclination angle k is 40 degrees is exemplified.

Each of the roof members 21, 22, 23, and 24 may have a shape of a square truncated cone as it goes to the top. According to the embodiment, the width c of the first lower surface 211 of the first roof member 21 located at the lower end may be 2.4 m and the width c of the fourth roof member 24 located at the upper end The width d of the top surface 242 may be 1.2 m.

In addition, the sizes of the lower surface and the upper surface of the roof members 21, 22, 23, 24 facing each other may be the same. The size of the first upper surface 212 of the first roof member 21 and the size of the second lower surface 221 of the second roof member 22 coincide with each other, The size of the upper surface 222 of the third roof member 23 and the size of the third lower surface 231 of the third roof member 23 coincide with each other and the size of the third upper surface 232 of the third roof member 23, The size of the fourth lower surface 241 of the roof member 24 may coincide with each other.

Therefore, although the inlet (i) of the seawater flowing between the roof members is a vertical section, before the seawater is introduced into the housing space 50 of the rollover between the roof members, the flow of the seawater is transmitted to the roof member 20 and presses the side surface 203 and this pressing force F acts downwardly and acts as a restraining force for preventing the overturning reed 1 from being conducted. In order that the pressing force F acts as a restraining force for preventing the overturning reed 1 from flowing, the side inclination angle k should be 45 degrees or less, and in order that the flow of the seawater may act as a pressing force of a significant magnitude, The side inclination angle k is preferably 35 degrees or more.

Since the side inclination angle k of the side surface 203 of each roof member 20 is relatively slower than the inclination angle b of the square end truncated a shape a of the main body 10, It is advantageous to ride on the side surface 203 and enter the habitat 50.

The abalone has a habit of living in cracks and rock beds, rock walls, and rock surfaces of the rock, and the habitat 50 provides the optimal habitat according to the habits of the abalone.

The plurality of roof members (20) are vertically connected by a supporting member (30). The support member 30 has a shape vertically extending from a central portion of the plurality of roof members 20, and the shape of the cross section may be circular. That is, the support member 30 may be in a cylindrical shape. Accordingly, the seawater flowing into the habitat space 50 between the roof members naturally flows on the outer circumferential surface of the support member 30, and consequently, the stability of the overturning reptile 1 is improved.

At the center of the support member 30, upper and lower extension grooves 32 which are opened downward and extend vertically are provided. The cross section of the upper and lower extension grooves may be a square shape. The square cross section provides a surface on which the overturning can easily enter while ensuring a sufficient internal volume of the upper and lower extension grooves.

The abalone has a habit of living on cracks and rock beds, rock walls, and rock surfaces of rocks, and the upper and lower extension grooves 32 provide the optimal habitat for the abalone.

The surface of the fourth upper surface 242 of the roof member 24 located at the uppermost portion of the main body 10 is provided with the uneven surface 40. The uneven surface 40 has a shape in which a square protruding surface 41 and a square embedding surface 42 are alternately arranged in a horizontal first axis and a horizontal second axis direction perpendicular to the first axis . According to the embodiment, the length of one side of each square constituting the uneven surface may be about 0.17 m to 0.18 m. These uneven surfaces promote seaweed production.

In addition, the surface of the main body 10 may be provided with a geometric shade to promote the blooming of benthos necessary for the growth of the abalone.

The uneven surface can additionally be formed not only on the fourth upper surface 242 but also on the first to third upper surfaces 212, 222 and 232.

<Bridge>

The legs 80 extend downward from the bottom of the body 10 and extend downward at the four corner portions of the lower end of the body 10.

The legs 80 include a hexahedral shape. The upper surface of the hexahedron is connected to the first lower surface 211 of the first roof member 21 of the main body 10. The lower surface of the hexahedron faces the sea floor.

Two outer side surfaces 82 of the four sides of the main body 10 that are disposed outwardly from the tearing reed 1 form a vertical surface extending vertically downward from the main body 10. On the other hand, the two inner sides 84 facing the center of the overturned fishing reed 1 form an inclined surface inclined outward toward the downward direction. Accordingly, the legs 80 have a shape of an upper light-tight narrowing in which the cross-sectional area becomes gradually smaller toward the lower side.

The inner surface inclination angle j formed by the inner surface 84 with the bottom surface of the main body 10, that is, the first lower surface 211 of the first roof member 21 may be 50 to 60 degrees. In the embodiment, the inner surface inclination angle j is about 55 degrees.

The width m of the upper end of the leg 80 is wider than the width n of the lower end. In the embodiment, the width m of the upper end of the leg is 0.7 m, the width n of the lower end is 0.5 m, and the height l is 0.3 m.

The legs 80 are formed in such a manner that the cross-sectional area of the legs gradually decreases as the legs 80 go downward, and the cross-sectional area of the legs corresponding to the lower height position is included in the cross- Therefore, the settling is smooth. As a result, conduction stability is improved.

On the other hand, since the lower outer surface 82 is perpendicular to the inner surface 84 and the inner surface 84 is inclined outward, the soil S1 of the seabed surface S, Space, that is, toward the submerged space 60. The gravel-like subsurface gathers in the lower habitat space 60 function to block the main body 10 from falling down after the main body 10 is lowered to some extent. According to this structure, the lower living space 60 can maintain a space having a height similar to that of the living space 50 of the main body 10.

The height l of the leg 80 may be twice the height of the habitat 50 and the height 80 of the leg 80 may be set to 1 / 2, the height of the final lower style space 60 can be made to correspond to the height of the style space 50.

The eggs which are rolled up in the habitat 50 of the overturned reptile 10 are seated on the recessed surface 42 of the irregular surface to form seawater, It is not influenced by the flow, and other fish can not approach it, which can reduce the gentleness of the sedimentation column. The eggs scattered in the upper and lower extending grooves 32 of the tumbling reptile 10 are well seated on the sea bed facing the lower living space 60 and are not affected by the flow of seawater, You can reduce the grief of the spell.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the scope of the invention is not limited to the disclosed exemplary embodiments. It is obvious that a transformation can be made. Although the embodiments of the present invention have been described in detail above, the effects of the present invention are not explicitly described and described, but it is needless to say that the effects that can be predicted by the configurations should also be recognized.
