Description

TECHNICAL FIELD [0001] The present invention relates to a sea cucumber culturing apparatus having a floor formed with an organic material floating space,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an aquacultural aquaculture apparatus, and more particularly, to a aquaculture system having a shape capable of reducing the amount of wastes or sludge accumulated on the floor by improving the bottom shape of aquaculture tank. In particular, these farms can be applied to cultivating sea cucumbers by securing a space for floatation of organic matter on the floor by installing attaching devices in the aquaculture tank and separating them from the bottom.

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 cucumbers are the fish products preferred by Chinese people.

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.

Figs. 1 to 3 show a process of producing sea cucumber in a nursery culture form in the prior art. 2 is a side sectional view of the sea cucumber farm in FIG. 1, and FIG. 3 is a perspective view of an attaching machine used in the sea cucumber farm in FIG. 1;

These figures show a water tank 10 receiving water for breeding (water) for the preparation of sea cucumbers and a feeder 20 installed at regular intervals in the horizontal direction at the bottom of the water tank, An inlet 30 for feeding the breeding water to the inside of the water tank, and a discharge port 40 for discharging the breeding water inside the water tank to the outside. The conventional water tank for culturing the sea cucumber is provided with an attachment device 20 at the bottom of the water tank 10 and new water (raised water) is introduced into the water tank through the inlet port 30, And the water is discharged to the outside.

Normally, sea cucumbers are nocturnal, and during the daytime they live in seclusion in a corner, but they usually crawl at night and feed themselves. Due to such wetting, the attaching device 30 has a corner shape that the sea cucumber likes, and at the same time, the floating materials in the feed or the breeding water adhere to the surface of the attaching device.

The specific shape of the attaching unit 20, which is indicated by a substantially rectangular parallelepiped in Figs. 1 and 2, is shown in Fig. The attaching device 20 is composed of a plurality of wave plates 23 and a holder 25 for receiving these wave plates 23. A plurality of the wave plates 23 are arranged side by side and a plurality of wave plates 23 arranged in this manner are supported by the holders 25 and placed on the bottom of the aquarium. The wave plate 23 may have a flat shape or a wave shape having a constant curved surface.

When the attaching device 20 is placed on the bottom of the sea cucumber culturing tank, feeds or suspended matters in the feed water adhere to the wave plates 23, and the sea cucumber crawls on the surface of the wave plates 23, And cultivated. In other words, when a fine powder feed to be fed to the sea cucumber is administered in a water tank, the powder feed floats in water and adheres to the bottom of the attachment machine or the water tank.

However, in the bottom of the aquaculture tank, there are wastes such as feces and sludge of the sea cucumbers and sludge which are fed so that the sea cucumbers can feed the fishes, and the bottom portion of the bottom of the aquarium contains the feces Water is always settled. Therefore, the water environment in the bottom of the water tank is more turbid than the water environment in the upper water pool. Sea cucumbers living on the bottom of a tank bottom can be adversely affected by continued exposure to these environments.

Therefore, the aquarium should be cleaned regularly. In order to clean the water, the water in the water tank is discharged to the outside through the outlet (40) shown in FIG. 2, and then the waste water adhering unit (20) is transferred to another water tank and the waste water and the sludge are cleaned. At this time, in order to prevent the sea cucumbers from flowing out to the outside together with the breeding water discharged to the discharge port (40), a separate net should be installed in the discharge port (40) After the drainage water is completely drained out, the waste water and sludge on the floor are cleaned.

However, in order to clean such a water tank for culturing the sea cucumber, there have been many problems as follows.

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.

The present invention provides a farm structure that does not require cleaning of the bottom of the farm to improve the farming environment of the farm. In this way, the present invention not only reduces the manpower and cost of cleaning the farm, but also reduces stress caused by the breeding of fishes, especially sea cucumbers, in order to lower the mortality rate, .

The present invention relates to a water tank for storing breeding water; A groove formed in the bottom of the water tank; And a blower system for supplying air to the breeding water, wherein the jetting device for spraying air in the blower system is located in a groove formed in the bottom of the water tank.

The grooves may be circular, rectangular, or hexagonal in shape as viewed from above, and the side surfaces of the grooves have a shape inclined toward the center, and the injection device is disposed at the lowermost end of the grooves.

The inclined surface of the side surface of the groove may be a curved line or a straight line, and the injection device may be an injection nozzle or an air stone.

The present invention improves the shape of a tank bottom of a farm, effectively floats waste matter or sludge accumulated on the bottom of the tank by using an injection device such as an air stone, and thus has an advantageous effect of eliminating the need to clean the bottom of the farm.

The present invention also eliminates the need to exchange breeding water inside the farm, thus it is possible to prevent diseases introduced from the outside, to cut manpower and cost to be exchanged for breeding water, , And the heating cost can be reduced.

Disclosure of the Invention The present invention provides a living environment in which a sea cucumber grows by separating a space in which a sea cucumber is inhabited from a bottom part of a cultivating water tank by a certain distance. By arranging an attaching unit at a certain distance from the bottom of a water tank, There is an advantageous effect of providing a good environment for the culture of sea cucumbers.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

The aquarium aquaculture apparatus described below can be applied to various types of fishery products. However, for the sake of convenience, the following explanation will be given as an example of a sea cucumber farming culture of sea cucumber. Therefore, it should be noted that the expression 'sea cucumber farming' described below is not necessarily limited to sea cucumbers and can be applied to all kinds of fish that can be cultured in a coastal aquaculture farm.

FIG. 4 is a schematic perspective view of a sea cucumber aquaculture apparatus according to the present invention, and FIG. 5 is a schematic view of a blower system used in a farm of the present invention. 4, the apparatus for preparing a sea cucumber according to the present invention comprises a water tank 110 for storing water for inside of the sea cucumber, a water tank 110 installed at a predetermined interval in the water tank 110, (Not shown for convenience of explanation), and a blower system 200, 210, 220 for supplying air to the inside of the water tank. The applicator according to the present invention may be installed at a distance from the bottom of the water tank (120 in FIG. 6). Since the attacher itself has a shape similar to that of the attacher used in the prior art, a detailed description of the attacher itself will be omitted.

The reason why the attaching device is spaced a certain distance from the bottom of the water tank,

First, the bottom 120 of the sea cucumber aquarium 110 is not well suited for the sea cucumber's habitat because of the sedimentation of the sea cucumber in the excrement and feed of the sea cucumber. Therefore, the sea cucumbers are spatially separated from the bottom surface, In order to create a growth environment,

Secondly, the blower system described below blows air from the floor of the water tank, floats feed or organic matter near the floor, and the floating organic matter adheres to the attachment unit, so that the sea cucumber in the attachment unit eats the organic matter. This is because the attachment needs to be spaced a certain distance from the floor to ensure that the system has enough space to effectively inject air.

4 and 5, the blower system is a device for spraying bubbles by supplying air to the breeding water in a breeding tank. The blower system 200 includes a blower 200 for introducing and supplying outside air, And an injector 230 including a first flow path 210 and a second flow path 220 forming a path of air introduced by the blower and provided at an end of the second flow path 220 do. The second flow path 220 branches from the first flow path 210 and is disposed downward in a substantially vertical direction. A plurality of the first flow paths may be disposed on the upper side of the aquaculture water tank. The spraying device blows air supplied from a blower on the bottom of a water tank to float organic matter and the like, and may be formed in the form of an air stone, an injection nozzle, or the like. An air stone is a stone provided with a ventilation hole, and is installed inside a fish tank to spray air or the like.

6 to 7, a plurality of circular grooves 130 having a predetermined depth and width are formed in the bottom 120 of the pond according to the present invention. In the circular groove 130, Apparatus 230 is located. The circular groove 130 has a curved slope so that the air injected from the injector 230 installed below the circular groove can effectively float organic matter existing in the circular groove. Such an ejector ejects air or fine bubbles from the bottom 120 of the water tank 110 to float the organic matter around the bottom and supply oxygen to the water. Thus, it is possible to finely pulverize the waste matter in the breeding tank to keep it floating above the breeding water, to maintain the supply of sufficient oxygen necessary for the decomposition of the waste matter particles, and to remove waste matter and sludge It is advantageous in that it does not accumulate on the floor as it is sprayed by the jetting device and it is not necessary to clean the bottom of the farm.

In the drawing, the circular groove 130 has a curved slope and the injection device 230 is installed at the lowermost end of the circular groove. However, when the circular groove is not a curved slope, It may have a slope. That is, the circular groove may have a V-shape (inverted conical shape) and the injector may be positioned at the lowermost end of the V-shape.

In the vertical cross-sectional view of the bottom of the farm shown in FIG. 7, protrusions 135 protruding upward are formed on the bottom portion between the circular grooves and the circular grooves so that there is no flat surface. This is because, if there is a flat surface on the bottom portion existing between the circular groove and the circular groove, waste materials and the like may accumulate therein, and the waste matter present in the place may not be effectively floated The flat surface does not exist between the circular groove and the circular groove on the bottom of the water tank.

8 and 9 are views of a tank bottom of a farm according to another embodiment of the present invention. In the bottom of the farm in this embodiment, grooves having a certain depth and width are formed, and the top view of the top view is a hexagonal honeycomb (140 in FIG. 8) and a rectangular one (150 in FIG. 9) Respectively. In order to show that the groove has a downwardly inclined surface, a part of the groove in the figure is shown in a perspective view or a cross-sectional view.

A plurality of hexagonal or rectangular grooves 140, 150 are formed on the floor of the farm in this embodiment, and the jetting device 230 of the blower system is disposed in the grooves. The grooves 140 and 150 also have a curved slope so that the air injected from the injector 230 installed below the grooves effectively floats organic matter existing in the circular groove. The remaining structure is the same except that the shape of the groove on the bottom of the water tank of the shrimp is changed in this embodiment, so a detailed description will be omitted.

Although the above explanation is based on the case of culturing sea cucumbers, the bottom form of the aquaculture tank described above is applicable not only to the sea cucumber but also to other fish species. However, in case of a species other than sea cucumber, an attacher described as being disposed inside the farm is unnecessary, so it may be used.
