  As warming progresses in aquaculture in today's seas, seawater is spreading more and more quickly even if it has no adverse effects such as an increase in CO2 and obstruction of the growth of aquatic organisms due to sludge. It is a basic food plankton that makes the body of oysters and fish shellfish in particular, but the carbon dioxide that makes up the body of this plankton itself decreases, the seawater temperature rises due to warming, and CO2 becomes water due to death due to sludge dirt. Above all, the current situation is increasing.

  Under these circumstances, when CO2 dissolves and hydrogen ions increase, acidification proceeds and carbon ions are lost each time a neutralization reaction with seawater occurs. Plankton is known to be composed of calcium ions and carbonate ions in the sea, and if carbonate ions are lost, the growth is poor and the shell is difficult to form.

Therefore, the air hoses and pipes for pressure feeding used to send air with a compressor for the main purpose of maintaining the life of fish and shellfish, but these air holes are uniform and have the same average thickness. The air was almost the same and the same amount.
This is not effective because it has low oxygen density in fish and shellfish, water quality, and aquaculture, and it is not effective. To improve the aquaculture technology such as the improvement of the aquaculture technology such as the air hole for pressure feeding of the hose and pipe, the structure of the hole and the hose and the pipe itself are modified and improved for more purposes It is a thing.

  Between the underwater and underwater parts of the pneumatic feeding hose and pipe for aquaculture, three stages of holes with different thicknesses of sections, sections, small, medium, large are provided in stages, but continuously small, Rather than providing a medium or large hole, a portion without any holes is intentionally provided between the small, medium and large partitions. This is a point to attach (attach) aquaculture seed oyster wires and ropes that are different from conventional ones, and the stage-hole pneumatic feed hose for cultivation is characterized by a structure that allows the pipes and wires of the present invention to be installed integrally. And a culture method using pipes.

  In addition, the point to be noted here at the beginning (inhibition stage) is that in order to attach seed oysters to oyster shells (fry shellfish) efficiently in the water (underwater), the output of pumping air is about 2 / 10th Is generally ideal. This is also a treatment for stably depositing juveniles on the target applicator collector (in which oyster shells are linked), which become deposited larvae called stopers within about 3 weeks after fertilization at a water temperature range of 21-26 ° C. After confirming these things well, it is a means to perform by air output.

  Since the present invention is a method for cultivating pneumatic hoses and pipes for aquaculture using large, medium, and small stage holes, when this is used, it is fed by a single hose and pipe. Since the air holes are structured in a stepwise manner, three types of bubbles are output at the same time to become mixed three bubbles, which are integrated with high density.

As described above, the degree of convection due to the water in the seawater is increased and the oxygen dissolution rate is improved. In particular, in the drooping method of oyster farming, the upward convection is used from the bottom of the sea toward the upper part. It happens effectively.
This means that the bottom seawater with a low water temperature falls to the top. At the beginning of use, important oyster larvae tend to adhere to oyster shells, and a very favorable effect is produced for oyster culture.

  In addition, this also has an effective effect on plankton in seawater, and in addition, the adhesion of dirt, the growth and development of cultured oysters, the vitality of growth, and the degree of nutrient uptake are increased, resulting in death. This reduces the amount, increases the yield rate, and contributes to the larger size of the harvest.

Furthermore, as a synergistic effect, if it becomes difficult to attach deposits such as sludge, purple shellfish and algae attached to oyster shells, the taste can be sufficiently improved.
In addition, it is possible to reduce the sediment under the seashore, which is a problem, and at the same time, there is a synergistic effect such as reduction of bad smell and improvement of freshness. In order to demonstrate the multipurpose effects as described above, the small, medium and large holes have different thicknesses, and there is no hole provided partly between the sections. Since the hose and pipe of the present invention can be easily attached to the seed oyster wire and rope, the effective aquaculture effect is improved.

  In the following, the best mode for carrying out the present invention will be described. In the underwater portion of each aquaculture pneumatic hose and pipe, small, medium and large step holes, holes and holes Darely provide a part without holes in the partitioning section, but if the foam is output by compressor pressure so that the output bubbles are output simultaneously from each hole, three types of mixed bubbles are simultaneously formed from the bottom to the upper layer It will be lifted up.

Next, if the explanation is made step by step according to the drawings, first, the compressed air of the symbol 1, 1 is extended to the symbol 2, with the joint wire jack of the target wire and pipe.
However, since the underwater (underwater) part of this extension pipe has the structure as described above, the symbol of this body structure, 3 is the section between the pneumatic feeding hose and pipe for underwater (underwater) aquaculture A small hole section, a middle hole section, and a large hole section section are divided into stages and each hole section is provided in a stepwise manner. Symbols 4 are small, medium, and large holes and holes. The part without a hole is provided between the divided sections.

  In this one, the front side where air is sent is a symbol, 5 is a small-diameter hole, symbol 6 is a medium-diameter hole, further symbol, 7 the tip is a large-diameter hole, Reference numeral 8 is a shut-off portion for pressure-feeding air from the compressor. Therefore, the air symbols, 5, 6, and 7 of different forms pumped from each hole in the above-mentioned stage are simultaneously output to the water (underwater), and the lower layer portion according to the row of cultured products and oyster persimmon seeds It is a form of aquaculture method with a structure in which upward convection occurs in the entire 9-foot block as mixed air bubbles in the upper layer.

In the following, the present invention will be described. First, the symbols of the present invention, the three aquaculture pneumatic hoses and pipes one by one, the symbols, and the conventional symbols in the four parts respectively. , I will attach and attach a rope with 9 kinds of oysters and a wire row.
This means that the entire applicator (collector) with a row of seed shells is integrated with the three-stage hole hose and wire on land in advance for the purpose. As an effective method, a wire or rope for seed oysters is spirally wound on the land in advance from the upper side (upper sea side) to the lower side (sea bottom side) in advance on the ground, and the entire method is carried out.

  It is only in this spiral form that the effective effect of staged bubbles on the top and bottom and bottom to top of the seed oyster row is exerted especially on each row of oysters, and also on the whole cocoon in the drooping culture method. However, a simultaneous effect occurs.

  In addition, when the air for pumping reaches the underwater (underwater) part of the hose and pipe, the whole seed oyster and the row are integrated and become light in the hydrogravity relation with water. The weight is attached and the stability is measured.

  By the way, when enforcing the straw shelf, considering the situation of the seawater site, the state of the seed oyster, it is done for each of the seed oysters that are suspended from the shelf, or one by one, or Alternatively, a single line interval, a triple line interval, or a six line interval may be used. Ideally speaking, if it is applied to all of the wire and rope of the row type oysters to be lowered, the oxygen supply rate in the seawater will increase, and at the same time, the water with low water temperature at the bottom of the seawater will synergistically improve the overall foam It is generated as a rising convection water of the symbol 13 by the rising force.

According to the present invention, it is said that there is no conventional method for underwater (underwater) organisms, especially in the oyster drooping method culture, in which the shape of air bubbles is changed into mixed bubbles in the aquaculture industry and used widely for various purposes. Karo.
In such a situation, water quality (seawater), seed oysters individually and one by one whole oyster row, subsidence sludge generated from aquaculture, phytoplankton activation method necessary for oyster growth, etc. The problem is solved and dealt with, and the point that it can be used and used easily in the work is emphasized and used in the aquaculture industry (especially in oysters).

Therefore, between a single pneumatic hose and pipe for aquaculture underwater and underwater, a small hole section, a middle hole section, a large hole section, and so on Divide each hole.
This is because a small hole is formed on the front side, a central hole is formed in the center, and a large hole is formed on the top end between a single pneumatic hose and pipe for aquaculture (in the seawater). However, I would like to emphasize that, in order to deal with obstacles such as the rest of food, algae, and other deposits that are problematic in the cultivation management such as nets, etc. By attaching the invention to the bottom and sides, not only defense, but also by utilizing this, aquaculture that can be easily managed and the combined use effect for the target breeding organism and aquaculture net is demonstrated, leading to an improvement in self-sufficiency rate It is an invention that also becomes a new industrial method.
