Description

Marine farm using fiber gabion and method of fish-breeding using the same}

The present invention is intended to construct a sandy bottom with a calm flow rate and reefs or stone graves, which are essential conditions for shellfish or sea cucumber farming, and a fiber gabion made of aggregate and shells forming numerous delicate holes, a habitat equipped with a fish reef for habitation. It relates to a fiber gabion-based offshore aquaculture structure that can be arranged around a space to lower the current flow rate and serve as a shelter, and a marine aquaculture method using the same.

Among marine organisms, sea cucumbers or shellfish are sensitive to the living environment, so it is necessary to create a careful habitat environment. In particular, sea cucumbers or shellfish have clear water quality due to smooth flow of algae, slow current flow, and sandy bottoms equipped with reefs or stone graves as their main habitat conditions.

In addition, each type has an appropriate water temperature and salinity. For example, most sea cucumbers grow fastest at water temperatures of 8 to 10 degrees, and the survival salinity is 25 to 30%, and the water temperature exceeds 28 degrees or the salinity is If 20% persists, they die.

However, considering the survival temperature and salinity of sea cucumbers or shellfish, the space suitable for aquaculture is in the sea at a depth of about 5 to 50 m, so it is difficult to reduce the current flow rate, which is a key condition for the living environment of sea cucumbers or shellfish. In addition, since it was an environment where attacks by surrounding natural enemies were frequent, the farming efficiency of sea cucumbers or shellfish was not high in the prior art.

As a representative example, in the sea cucumber island pilot project, the ratio of sea cucumber harvest to the number of released individuals was only 40 to 45%. The biggest reason for this was that chisam was swept away or scattered by high-speed currents and became a prey for natural enemies.

In this way, in order to improve the efficiency of sea cucumber or shellfish aquaculture, it is necessary to have a fish reef that can significantly lower the flow rate of algae flowing into the farm and allow the larvae or larvae to escape and hide from natural enemies.

Hereinafter, an embodiment of the present invention will be described in detail based on the accompanying drawings FIGS. 1 to 6.

On the other hand, in the drawings and detailed description, illustrations and references to configurations and operations that can be easily understood by those skilled in the art from general technical configurations are simplified or omitted. In particular, in the drawings and detailed description, detailed descriptions and illustrations of specific technical configurations and actions of elements not directly related to the technical features of the present invention are omitted, and only the technical configurations related to the present invention are briefly shown or described. did

The present invention relates to a structure for marine aquaculture, and chisam and juvenile mean relatively small baby sea cucumbers and young shellfish, respectively. However, chisam or chisam mentioned below may be used in the same sense as sea cucumber or shellfish.

In addition, the present invention relates to a structure for aquaculture based on fiber gabions (10). Fiber gabions 10 may further include porous materials other than aggregate and shells, as shown in FIG. 5 . Specifically, the fiber gabions 10 may include aggregates and shells, nets surrounding the aggregates and shells, and a suture rope for sealing the nets to prevent the aggregates or shells from escaping to the outside.

At this time, the mesh is woven with polyester, which is an eco-friendly fiber, and may be formed to withstand a material of 24 tons. The net eye of the mesh may be adjusted according to the size of the aggregate or shell to be included, and is preferably 80 to 300 mm. And the suture rope may be configured to be ssamji suture with one or more strands.

Specifically, the fiber gabion 10 may be configured such that the aggregate is disposed to occupy 65 to 75% of the total volume, and a shell network containing a separate shell is filled on top of the aggregate. That is, when the volume ratio of the aggregate and the shell is as described above, the shell serving as a fertilizer and the aggregate in which the reef attaches and inhabits are balanced, and a high reef formation rate can be exhibited. In order to perform this role, it is possible to hang caps, kelp, etc. on the fiber gabions 10 and put them in the water. At this time, the capricorn, kelp, etc., which are introduced together can inhabit and proliferate in the aggregate of the fiber gabion 10, and thus the fiber gabion 10 can function as a fish reef.

In addition, a block-type fertilizing material 700 is included inside the fiber gabion 10 so that food can be provided.

The network eyes of the mesh containing the aggregate are formed at least 70 mm or more so that sea cucumbers or shellfish can move in and out of the fiber gabion 10 through the mesh eyes or move between the aggregates. On the contrary, it is preferable that the mesh eyes of the shell net containing the shells are formed at about 40 mm so that the aggregates that are relatively smaller than the aggregates do not escape to the outside.

The fiber gabion-based offshore aquaculture structure according to the present invention, as shown in FIG. It includes a space protection net 500, a hiding reef 600, and a block-type fertilizing material 700.

The first wave breaking line 100 and the second wave breaking line 200 are formed by arranging fiber gabions 10 including aggregates and shells. At this time, the second wave wave line 200 is formed inside the first wave wave line 100, and may be formed as a multi-layered line as shown in FIG.

The first wave breaking lines 100 are arranged to form a first set shape of a first set length, and the second wave breaking lines 200 are arranged to form a second set shape of a second set length. The first set shape and the second set shape may form various shapes such as a rectangle, a circle, and a triangle, and the first set shape and the second set shape may be the same or similar to each other.

Specifically, the first set shape and the second set shape may form a rectangular shape as shown in FIG. 1, and the first set length and the second set length may have a difference of 4 to 6 m from each other. Through this configuration, the first wave breaking line 100 and the second wave breaking line 200 can be optimized for an environment with a water depth of 7 to 15 m, which is rich in conditions of a sandy bottom with a slow flow rate and reefs or stone graves. However, the first set shape and the second set shape, the first set length and the second set length may be flexibly adjusted according to the strength, waveform, and encounter frequency of the current.

More specifically, the first wave line 100 is lined with fiber gabions 10 stacked in two or more layers. For example, as shown in FIG. 2, two fiber gabions 10 are disposed on the bottom surface in contact with each other, and another fiber gabion 10 is disposed at the center of the top of the two fiber gabions 10 to form a two-layer structure. can

Specifically, the first wave line 100 may be stacked so that the fiber gabions 10 form a pyramid shape, and inclined surfaces 110 are formed on both sides. With this configuration, the ocean current energy pushed from the outside is primarily dispersed along the inclined surface 110, and the dispersed energy is secondarily dispersed while being dispersed into numerous holes formed by the skeleton and shell of the fiber gabion 10. This can greatly increase the breaking efficiency.

On the other hand, as shown in FIG. 1, each fiber gabion 10 constituting the second wave line 200 and the habitat space formation line 300 is smaller than the fiber gabion 10 constituting the first wave line 100, , The fish reef 600 for hiding is made up of a smaller scale than each fiber gabion 10 constituting the second wave line 200 and the habitat formation line 300, structural structural Due to the characteristics, it is possible to increase the possibility that the habitat space 310 is protected from external forces such as algae. In addition, the hidden fish reef 600 is formed on a smaller scale than the fiber gabions 10 arranged outside, so that it may be difficult to find by natural enemies, etc., thereby improving the function of the offshore fish farm structure.

Specifically, each fiber gabion 10 constituting the first wave breaking line 100 may be made on a scale of 6 to 8 ton, and each fiber gabion 10 constituting the second wave wave line 200 is 4 to 6 ton can be made on the scale of Habitat space forming line 300 is made in a scale of 1 ton or less, so that the effect of hiding sea cucumbers or shellfish can be further improved.

The habitat formation line 300 is formed by arranging the fiber gabions 10 like the wave wave lines 100 and 200, and is arranged along the edge of the habitat space 310 inside the second wave wave line 200 .

Specifically, as shown in FIG. 1, the structure for marine aquaculture according to the present invention has one first wave breaking line 100, two second wave breaking lines 200, and a habitat forming line 300 along the inside from the outside. As a result, a total of four fiber gabion 10-based crushing lines can be arrayed. With the above configuration, the offshore aquaculture structure according to the present invention can stably reduce the speed of algae flowing into the habitat by inducing edge crushing along four or more crushing lines.

On the other hand, the habitat space 310 is a key place where sea cucumbers or shellfish are cultivated, and one or more fish reefs 400 for habitat, fish reefs 600 for hiding, and one or more block-type fertilizing materials 700 are disposed. The habitat space 310 may have a shape such as a rectangle, a circle, or a triangle according to environmental conditions.

Preferably, the habitat formation line 300 may be formed in a 25 m long square, and in this case, the first wave wave line 100 may be formed in a 50 m long square. When the first wave wave line 100 and the habitat formation line 300 are formed in a square shape as described above, forming a plurality of first wave wave lines 100 and habitat formation lines 300 of the same shape adjacently can be useful for That is, several square first wave breaking lines 100 can be placed in contact with each other. In this case, the first wave breaking line 100 at the contacting portion is formed as only one line to reduce the initial structure installation cost. have.

The fish reef 400 for habitation is disposed inside the habitat space 310 so that chisam or juveniles hide, and may be made of a porous porous concrete material. In order to prevent the loss of the larvae or larvae from an external natural enemy or external force, the larvae or larvae may be put into the input space 410 formed by arranging a plurality of fish reefs 400 for habitation. That is, a plurality of fish reefs 400 for habitat may be arranged along the circumference of the input space 410 .

Specifically, when the reef 400 for habitat forms a square shape, the reef 400 for habitat may be arranged to be in contact with each side of the rectangular input space 410 as shown in FIG. 3 . Thereafter, by inserting ginseng or larvae into the input space 410 and covering the top of the input space 410 with another fish reef 400 for habitation, it is possible to eliminate the risk of loss of ginseng or prawns by birds or being attacked by natural enemies. have.

The habitat protection net 500 is to prevent the invasion of the habitat space 310 by external spores, and is disposed to cover the upper part of the habitat space 310 as shown in FIG. 4 . The size of the habitat protection net 500 can be adjusted to a size that can cover only the habitat space 310 or cover up to the first wavy wave line 100.

Such a habitat protection network 500 may be connected and fixed to the fiber gabions 10 constituting the wave breaking lines 100 and 200 or the habitat formation line 300, or may be installed separately on the bottom surface.

Habitat space protection net 500 is configured such that seawater penetrations 510 are formed so that birds can enter and exit the habitat space 310 flexibly. The size of the seawater penetration hole 510 may be adjusted in consideration of the size of a natural enemy according to environmental conditions.

The hiding fish reef 600 serves as a shelter that allows the larvae or larvae to escape from the infiltration of external enemies, and increases the survival and retention rate of sea cucumbers or shellfish in which the larvae or larvae grow later to increase the preservation rate of the growing population. induce to increase

By suspending seaweeds such as seaweed and kelp on the hiding reef 600 and putting them into the water, it is possible to induce the transplantation and spread of artificial seedlings, thereby serving as a mid-sea reef reef and hiding ratio of sea cucumbers or shellfish that are friendly to fishing reefs can be further increased.

The fish reef 600 for hiding may include aggregates and shells like the fiber gabion 10 as shown in FIG.

The block-type fertilizing material 700 is distributed in the habitat space 311 to supply food and increase growth of larvae, and is composed of natural materials such as seaweed, anchovies, and kelp.

This block-type fertilizing material 700 is not a powdered natural material itself, but is reconstructed into a brick type as shown in FIG. 1 by mixing at least one of tidal flats and soil. That is, the block-type fertilizing material 700 is a mixture of at least one of tidal flats and soil, and unlike powder-type fertilizing material, it is not immediately swept away by algae, but slowly melts in water and mixed with bedrock sand. Accordingly, the block-type fertilizing material 700 can become food for sea cucumbers or shellfish as it is deposited in the habitat space 310, so that the cycle of distributing the fertilizing material becomes very long compared to the powder-type fertilizing material.

The block-type fertilizing material 700 may be evenly distributed in the habitat space 310 or directly injected into the input space 410. In addition, by including the block-type fertilizing material 700 in the hidden fish reef 600, young or grown sea cucumbers or shellfish can be induced to move and be supplied with food.

Next, as using the fiber gabion-based offshore aquaculture structure as described above, the offshore aquaculture method will be described in detail.

As shown in FIG. 6, the marine aquaculture method using the fiber gabion-based marine aquaculture structure according to the present invention includes the step of distributing chisam or young shellfish (S10), the aquaculture step (S20), the harvesting step of sea cucumber or shellfish (S30), and the purification of structures for aquaculture. It is configured to repeatedly perform step S40.

In the step of distributing chicken breast or young shellfish (S10) to the fish reefs 400 for habitation in the above-mentioned paragraph 1, as shown in FIG. can

Specifically, the chicken breast or baby eggplant distributing step (S10) may include an input space forming step (S11), a chicken breast or eggplant inputting step (S12), and an input space protection step (S13). In the input space forming step (S11), fish reefs 400 for habitat are arranged in a row along the circumference of the input space 410. In the step of inserting chicken breast or baby chicken (S12), chicken breast or baby chicken is put into the input space 410. In the input space protection step (S13), the fish reef 400 for habitat is disposed above the input space 410, and external exposure of the input space 410 is blocked.

The aquaculture step (S20) is a step in which the ginseng or larvae are left on the fish reef 400 for habitation during the growth period of the larvae or larvae distribution step (S10), and the above-described block-type fertilizing material 700 is introduced to sea cucumber or It can serve as food for shellfish. The set growth period of the aquaculture step (S20) may be preferably 3 years.

Specifically, the farming step (S20) may include a first leaving step (S21), an input space exposure step (S22), and a second leaving step (S23). In the first leaving step (S21), the chisam or young plait introduced during the first set growth period is left unattended. In the input space exposure step (S22), a part of the input space 410 is exposed to the outside as the fish reef 400 for habitation on the top of the input space 410 is moved. In the second leaving step (S23), the chisam or young plait introduced during the second set growth period is left unattended. The sum of the first set growth period and the second set growth period becomes the set growth period, and at this time, the set growth period is preferably three years in total.

The sea cucumber or shellfish harvesting step (S30) is a step in which sea cucumber or shellfish are harvested after the set growth period of the aquaculture step (S20), and the user harvests the sea cucumber or shellfish grown in the habitat space (310).

The purification structure for aquaculture step (S40) is a step of inducing purification of the structure for aquaculture by natural algae, and is a configuration that eliminates the need to separately clean the structure for aquaculture. Through this step of purifying the structure for aquaculture (S40), the unnecessary materials accumulated on the structure for aquaculture are naturally dispersed by the ocean current, so that the internal environment can be regenerated.

As an example for effectively using the aquaculture method according to the present invention described above, four structures for aquaculture based on fiber gabions according to the present invention may be provided. In this case, after the first year of ginseng or shellfish distribution step (S10), the 3-year aquaculture step (S20), and the last year after the sea cucumber or shellfish harvest step (S30), the purification of the structure for aquaculture ( S40) is performed. This is in consideration of both the growth rate of sea cucumbers or shellfish and the purification rate of the offshore aquaculture structure according to the present invention.

As such, if the marine aquaculture method in which each of the four marine aquaculture structures is applied with a year apart from each other is used, the user can harvest sea cucumbers or shellfish from any one of the marine aquaculture structures every year. That is, the user can harvest fresh and large-sized sea cucumbers or shellfish at a high population rate every year.

As described above, although the fiber gabion-based offshore aquaculture structure and the offshore aquaculture method using the same according to an embodiment of the present invention are shown according to the above description and drawings, this is only an example and the technical idea of the present invention Various changes and changes are possible within the range that does not deviate.
