Abstract
Description
The present invention relates to an aquaculture apparatus and a method for culturing a marine organism using a cage for aquaculture, in which fresh seawater is introduced from a seabed surface through a motor pump and fed to a certain portion of a pipe flowing through the incoming seawater, And feeds the necessary amount of feed to the feed cage which is flowed in the mixed state of the sea water and the feed which are flowed in together and is fed into the feed cage provided inside the cage for the sea floor, Aquaculture apparatus and aquaculture method.
In general, aquaculture is a species that produces seeds of aquatic organisms that are used for food or other purposes by raising or growing seeds in a certain area, including seedling and fertilization.
Recently, the demand for seafood such as sea cucumbers has been greatly increased, and the income of fishermen has been greatly increased. Interest in health and wellness has been increasing in the echinoderm, the echinoderm, and in the eastern regions such as Korea and China, sea cucumber is the best stamina food And popularity is increasing day by day. Especially, sea cucumber is a fishery product preferred by Chinese people.
Sea cucumber belongs to the echinodermatidae family and is widely distributed in shallow waters. It is called "sea cucumber" because it is called "sea rats" because it hides in a rocky place during the day and is active at night. It is called sea cucumber in the West because it is like cucumber.
The exercise consists of twenty tentacles, tubal legs and right legs. Sea cucumbers grow at a temperature of 15 to 18 ° C, but they rarely eat food at high temperatures. Therefore, the digestive tract is degenerated. When the water temperature exceeds 25 ℃, the digestive tract becomes smaller and becomes the minimum, which is the summer season. Due to the ecological and physiological characteristics of sea cucumber, not only the growth period is short in our natural environment, but also there is no technology to overcome it.
There are two kinds of blue sea cucumber and red sea cucumber in sea cucumber. There is not much difference in taste, but the sea cucumber is highly marketable. It spawns in early spring in late spring, but goes into summer sleep after spawning.
Generally, sea cucumbers are intensively produced around April to June, they are consumed almost in China, and sea cucumbers are no exception to the general phenomenon of depletion of water resources, and production in nature is gradually decreasing.
As a result, the distribution of artificial seedlings is in urgent need and is attracting attention as a high income form in the farms of the East Coast.
Conventionally, a method has been adopted in which a large number of stones are transported by a carrier such as a barge and dropped on the bottom of a farm to enable the sea cucumbers to live.
But. Thus, the sea cucumber grows at a temperature of 15 ~ 18 ℃, but at the time of high water temperature, it hardly feeds. Therefore, the digestive tract is degenerated. When the water temperature exceeds 25 ℃, the digestive tract becomes smaller and becomes the minimum, which is the summer season. Due to the ecological and physiological characteristics of sea cucumber, not only the growth period is short in our natural environment, but also there is no technology to overcome it.
In order to clean the fish tank for aquaculture, a lot of time and manpower must be put in. When the water is discharged to the outside for cleaning the tank, there is a problem that the feed fed together with the waste products is also lost and the loss is caused. There was also a problem that it might leak out.
Especially, frequent cleaning of the aquaculture tank causes the problem that the cultured objects are not stabilized, that is, the serious problem that the cultured sea cucumbers suffers from stress.
In addition, it is advantageous to darken the inside of the farm as much as possible due to the nocturnal habit of sea cucumber. It is very difficult to clean the water tank in a dark environment, and the newly introduced water should be heated or cooled to the temperature necessary for culturing the sea cucumber. There is a problem that additional fuel is consumed. Therefore, it was necessary to reduce the number of times of cleansing the fish tank as much as possible.
Conventional methods of cultivating sea cucumbers by the above-mentioned stone-dropping method are not so much concerned about loss of water even at a relatively high flow rate because relatively large stones are heavy. However, the living space such as sea cucumbers is narrow and insufficient, There are many habitats such as sea cucumbers, but there is a lot of concern about the loss of water despite the slow flow rate.
Therefore, after a long period of time, the originally dropped state can not be maintained, and the sea water is lost due to the rapid flow of seawater in the farm.
In addition, the above-mentioned general reefs can not only be tilted according to the bottom condition, but also have a problem that they are no longer able to function as the habitat of sea cucumbers due to being buried in mudflats or tidal flats after a long period of time.
Therefore, the survival rate is higher than that of the discharge type, and it can be easily transported by a carrier such as a barge ship or a barge, and can be released from a farm, and is not lost by the flow of quick seawater inside the farm, , There has been a demand for a method of culturing cages for sea cucumbers having a large habitat in which sea cucumbers can be inhabited and feeding and cage cleansing operations which are convenient for the feed supply and treatment of feed by-products of the cage .
In addition, if the sea cucumbers can be cultivated together with abalone, there will be an advantage in terms of profit.
SUMMARY OF THE INVENTION Accordingly, the present invention has been made in view of the above problems, and it is an object of the present invention to provide an apparatus and a method for supplying fresh seawater from a seabed surface through a motor pump and feeding a certain portion of a pipe, The system is designed to feed and feed the required amount of feed. The feed water is then mixed with the sea water and feed, and fed into the feed cage inside the cage.
When the feed cage of the aquaculture cage is supplied with seawater and feed,
First, the feeds that come with seawater stay inside the feed cage, so that the feed gradually breaks down into fine particles along with seawater and moves to the cage outside the cage,
In addition, when the seawater is introduced with the feed, by-water of the incoming seawater is used to purify the inside of the cage by discharging the by-products of the feed which is present in the feed cage before the outside of the cage. And aquaculture apparatus using the aquaculture cage having the characteristics capable of purifying the cage.
As described above, according to the aquaculture apparatus and the aquaculture method using the aquaculture cage according to the present invention, fresh seawater is introduced from the seabed surface through the motor pump, and when the seawater is introduced together with the feed, It has the characteristic of purifying the inside of the cage by discharging the by-products of the feed which is present in the inside of the feed cage by the water pressure of seawater to the outside of the cage, and it has the effect of feeding the feed and cleaning the cage. The cage of the cage is not smooth in circulation, and when the feed of the aquaculture is corroded or eutrophied in the cage, aquatic organisms are often lost due to the deterioration.
In addition, there is no worry about loss of water at a certain flow rate because the large stone is dropped on the sea surface due to the heavy weight of the seedlings. However, the living space such as sea cucumbers is narrow and insufficient. In order to solve the problem of concern about loss even though the flow rate is high,
In the present invention, the feedstuffs that are introduced with the seawater in the form cage are kept in the feed cage so that the feed is gradually broken down into fine particles along with seawater and moved to the cage outside the cage, As a result, marine organisms in the cage have the effect of increasing the amount of growth in a uniform natural environment.

Described additionally in the above description,
In the case of abalone or sea cucumber, aquatic organisms are living creatures in the bottom of the ocean floor. They are intended to enhance high added value in comparison with other conventional aquaculture methods in terms of survival rate, development and economy,
In the case of the aquaculture cage (50), the factor that inhibits the flow of the water due to residual feed byproducts and inhibits the propagation of aquatic organisms due to pollution and if it was a closed form cage, In order to solve the problem of the death of living marine creatures on the ground such as abalone,
In the present invention, the flow of seawater is smooth as in the natural state owing to a large number of pores on the outer wall of the
In addition, the aquatic organisms such as sea cucumbers such as sea cucumbers in the bottom have a suitable water temperature of 8 ~ 17 ℃, and when the temperature is below 17 ℃, the feeding activity is vigorous. However, when the temperature reaches 18 ~ 20 ℃, And when it reaches 24 ℃ or more, it will fall asleep in the period of summer (summer), and growth stops.
For this reason, in the present invention, in order to maintain the seawater temperature of about 8 to 17 캜 at the optimum water temperature of the seawater, if the cage is installed at a depth of 30 to 40 m, the proper water temperature is maintained regardless of the season It has the advantage of maximizing the survival rate and development status of aquatic organisms such as sea cucumbers.
In addition, since marine organisms inhabit the same floor as sea cucumbers do not like sunlight, it is necessary to reduce the stress by cutting off sunlight during daytime in general land farm and cage farm, but in the present invention, It is natural to cut off the sunlight. Even if the sunlight reaches 30 ~ 40m depth, the outside wall of the cage can not keep sunlight except the small hole, have.
For feeding. Generally On land and cage farms it is easy to supply as needed.
However, in the present invention, fresh seawater of the sea floor is transferred to the motor by the rotation of the motor, By feeding the feed through the flow pipe by means of the
Feeding of feed was done once every three days, preventing eutrophication inside the cage.
And because the habitat of sea cucumbers is inhabited by sand, mud, gravel and rocks, studies have shown that 50 g of sea cucumbers consume about 4.8 cc or 3.5 kg per year of sand and mud However, in order to make the environment of the most suitable sea cucumber in order to take the organic matter and the minerals precipitated in the sand and the tremble, not the digestion of the sand in practice, in the present invention, the gravel is laid on the bottom of the cage, It was created to breed in the same environment as the environment.
The aquaculture cage used in the present invention is made of stainless steel and zinc-plated reinforced product, and it is made of a material which does not rust and does not rust because it hardly breaks, so that it can be used semi-permanently and can be used semi-permanently. , Or by managing 20 ornamental cages that supply either sea water or feed at the same time, reducing labor and management costs.
It is not a large number of people to collect after 1 year ~ 1 year and 6 months after harvesting, but harvesting the cage for the bottom of the sea floor using a small marine crane. The system was put in a cage again, so that it could be cultured with a small number of people.
In the case of juvenile sea cucumbers (3 ~ 5cm) per aquaculture cage, 3,000 ~ 4,000 cucumbers are placed in the aquaculture cage, and the mature cucumber is grown to 20cm or more.
