DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of an apparatus for cultivating individual caves and a method for cultivating individual caves using the same according to the present invention will be described in detail with reference to the accompanying drawings.

The apparatus for cultivating individual caves according to the present invention includes a first breeding plate in which a plate-shaped grid of a certain size is formed, a space formed therein to accommodate the first breeding plate, and a plate-shaped grid of a certain size A second breeding board on which a net is formed and the size of the lattice network is larger than that of the first growing board, and a space is formed therein to accommodate the second growing board, and the distance between the nets is longer than that of the first growing board. It consists of a second mesh.

First, a first training board is prepared. The first growth plate is formed in a plate shape, and a lattice network of a predetermined size is formed. Here, oysters are grown on the upper part of the first breeding plate. And the size (A) of the lattice network in the first breeding board is set to 0.5 cm.

And, a first net accommodating the first training board is provided. A space is formed inside the first mesh to accommodate the first growth board. Here, a plurality of first growth plates may be accommodated inside the first net. In addition, the distance (B) between the nets in the first net is 0.5 cm.

A second training board is prepared. The second growth plate is formed in a plate shape, and a lattice network of a certain size is formed. Here, oysters are grown on the upper part of the second breeding plate. And the size (A) of the lattice network in the second growth plate is set to 0.8 cm.

And, a second net for accommodating the second training board is provided. A space is formed inside the second mesh to accommodate the second growth plate. Here, a plurality of second growth plates may be accommodated inside the second net. And the distance (B) between the nets in the second net is 1 cm.

Hereinafter, the method for cultivating individual oysters according to the present invention includes the first step of attaching oysters to a first breeding plate and cultivating inside the first net, and attaching the oysters nurtured in the first step to a second breeding plate, It consists of the second stage of training inside the second net.

First, in the first step, oysters are attached to the first breeding plate. Specifically, oysters with a leg length of 0.5 cm are attached to the first breeding board and nurtured inside the first net. At this time, the size (A) of the lattice network in the first growth plate is smaller than that of the oyster leg to prevent the growth plate located on the surface of the oyster from being caught in the lattice network so that the oyster grows well.

In addition, by minimizing the distance (B) between the nets in the first net, the attachment and growth of marine miscellaneous organisms is suppressed, and the overall weight of the first net is reduced to facilitate work. Here, the oysters are nurtured until the length of the oyster is 1 cm.

In the second step, the oysters nurtured in the first step are attached to the second breeding plate. Specifically, oysters with a leg length of 1 cm are attached to the second breeding plate and nurtured inside the second net. At this time, the size (A) of the lattice network in the second growth plate is smaller than the leg length of the oyster to prevent the growth plate located on the surface of the oyster from being caught in the lattice network so that the oyster grows well.

In addition, by minimizing the distance B between the nets in the second net, the attachment and growth of marine miscellaneous organisms is suppressed, and the overall weight of the second net is reduced to facilitate work.

Hereinafter, experimental contents for the individual burrow cultivation system and the individual burrow cultivation method using the same according to the present invention will be described in detail.

1. Survival rate according to the first breeding plate and the first net

Oysters with each length of 0.5 cm were attached to the first breeding board and nurtured in the first net, and the size of the grid in the first breeding plate (A) and the distance between the nets in the first net (B) were different. did In addition, all conditions were the same, and the survival rate was measured for each period.

1st training board
grid size
(A) 1st net
between nets
distance (B) survival rate (%) first after 20 days after 40 days after 60 days 0.1cm 0.5cm 100 86.5 73.8 61.5 0.3cm 0.5cm 100 83.2 74.1 60.5 0.5cm 0.5cm 100 92.8 84.5 78.2 0.7cm 0.5cm - - - - 0.9cm 0.5cm - - - - 0.5cm 0.1cm 100 85.1 66.6 50.1 0.5cm 0.3cm 100 90.2 72.5 53.6 0.5cm 0.7cm 100 91.0 74.2 52.3 0.5cm 0.9cm 100 83.2 67.1 51.5

As shown in Table 1 above, when the size (A) of the lattice network in the first growth plate was smaller than 0.5 cm, the growth plate located on the surface of the oyster was caught in the lattice network, and the survival rate of the oyster decreased. And if it is larger than 0.5 cm, there is a problem in that the oysters are separated from the first breeding plate.

If the distance (B) between the nets in the first net is smaller than 0.5 cm, the circulation between the inside and outside of the first net is not performed, resulting in a decrease in survival rate. Due to excessive attachment, circulation between the inside and outside of the first net was not achieved, and the survival rate of the oysters decreased.

2. Survival rate according to the second breeding plate and the second net

Oysters with each length of 1 cm were attached to the second breeding board and nurtured in the second net, and the size of the grid in the second incubation plate (A) and the distance between the nets in the second net (B) were different. . In addition, all conditions were the same, and the survival rate was measured for each period.

2nd training board
grid size
(A) 2nd net
between nets
distance (B) survival rate (%) first after 20 days after 40 days after 60 days 0.4cm 1.0cm 100 83.4 72.8 60.3 0.6cm 1.0cm 100 87.1 71.1 59.1 0.8cm 1.0cm 100 90.8 83.8 77.1 1.0cm 1.0cm 100 85.2 73.6 61.8 1.2cm 1.0cm - - - - 0.8cm 0.6cm 100 90.1 83.5 77.2 0.8cm 0.8cm 100 89.3 82.1 76.5 0.8cm 1.2cm 100 87.1 73.5 52.2 0.8cm 1.4cm 100 86.5 71.1 50.8

As shown in Table 2 above, when the size (A) of the lattice network in the second growth plate was smaller than 0.8 cm, the growth plate located on the surface of the oyster was caught in the lattice network, and the survival rate of the oyster decreased. And if it is larger than 1 cm, there is a problem in that the oysters are separated from the second breeding plate. In addition, when the size of the grid (A) was 1 cm, marine life was excessively attached to the second breeding plate, and the survival rate of oysters decreased.

When the distance (B) between the nets in the second net was greater than 1 cm, marine organisms were excessively attached to the second net and the survival rate of oysters was lowered. If B) is less than 1 cm, it is preferable to use 1 cm because the cost is excessive and the weight of the second net itself is excessive, reducing work efficiency.
