Description

Technical Field [0001] The present invention relates to a crab culture apparatus capable of individually culturing crabs,

The present invention is based on the fact that when megalopa larvae are grown in the larval stage of the live seedling, in the baby larvae, in the formation of the carapace and in the last larva stage where the decapitation begins, the megalopa larvae are separated , A separate culturing apparatus capable of individual culturing of separated megalopa larvae separately from the isolation culture vessel and isolated from the culture broth.

Generally, artificial seedling production methods of live crabs produce crab spawning through mock egg laying, hatching and larval culturing. In other words, the production method of racial horses is composed of mock egg laying - hatching - larval culturing stage.

Eggs from spawning crabs are converted into larvae up to about 100% until hatching, and the larvae are cultivated to produce beef crabs. Conventional larval culture techniques are collective aquarium culture methods, which collectively cultivate larvae in aquariums.

The larvae can be composed of Joea larvae 1 ~ 5 and megalopa larvae, and through the stage of Joea larvae, in order to eat the floating food in the aquaria during the last stage, There is a habit of eating food. After the Joea larvae, the megalopa larvae develop a metamorphosis in which the pellets and nippers are produced, and the weight becomes heavy, so they go to bed under the water tank and eat the big food at the bottom of the tank. It grows into beef.

However, when the megalopa larvae are cultivated in aquaculture as in the past, the official phenomenon (cognition phenomenon) is serious And the survival rate of live crab survival to beating was lowered.

In other words, since the larvae were cultivated by the group tank method in the past, due to the phenomenon that the large number of megalopa larvae were molted without being cultured to the beef due to the official phenomenon, the rate of viable survival was extremely low, The rate of cultivation in the beef stewers, that is, the yield of the beef stew, was very low.

Hereinafter, an apparatus for larval culture of crabs capable of individual culture according to an embodiment of the present invention will be described with reference to the drawings.

The apparatus for culturing larvae of the present invention includes a water tank 10, a larval individual separation unit 100, a larval transfer unit 300, and a larval isolation culture unit 500.

The water tank 10 is a water tank in which the larvae are primarily cultured by receiving water therein, and the larvae individual separation units 100 are contained therein. Here, water becomes seawater when the larva is larvae of sea crabs, and fresh water (fresh water) when it is fresh water gain.

As shown in Figs. 1 and 4, the larvae individual separation unit 100 is accommodated in a plurality of rows and columns, and may be arranged in two or more layers in the upper and lower stages.

The larval individual separation unit 100 is a structure for separating the megalopa larvae so that the megalopa larvae are individually isolated while sinking by their own weight.

That is, the larvae cultured in the water tank 10 are cultured as megalopa larvae through the larvae of Zoaea. During the Zoaea larvae, they are cultured while floating and floating in the water of the aquarium, When a megalopa larva is weighed in weight, it sinks to the bottom of the water tank and leads to a low life. In this way, the larvae are separated from each other while being submerged in the larvae separate separation unit 100 in the course of being cultured as a megalopa larva from the larvae in the water tank 10 and submerged into the bottom of the water tank.

Specifically, the larvae individual separation unit 100 includes a frame member 110, a collection plate 120, and a valve plate 130.

The frame member 110 is formed in a rectangular frame shape as shown in FIGS. 5 and 6, and one side wall 112 of the four side walls 111 is configured to be hingeable by the hinge h.

At this time, the interval between the upper and lower insertion grooves 114 and 115 into which the valve plate 130 and the collecting plate 120 are inserted can be adjusted according to the species of the crab.

In the present invention, the larvae dividing openings 121 of the collecting plate 120 are sized to accommodate one megalopa larva which is usually about 1 cm or so, depending on species. That is, it is preferable that the two megalopa larvae are not accommodated in the larvae separating port 121 at the same time, but only one megalopa larvae can be accommodated.

That is, in the process of growing the megalopa larvae (c, see Fig. 1) in the water tank 10 and submerging megalopa larvae to the bottom of the water tank 10, they are placed on the bottom of the water tank 10 One by one into the larvae separating port 121 formed in the collecting plate 120 of the larvae individual separating unit 100, which is separated and accommodated.

In other words, the megalopa larvae are separated one by one as they are housed in the separate larvae 121, and the valve plate 130 is installed at the lower part of the collecting plate 120, It can be held in the isolated state by being received in the larvae separating port 121 of the collecting plate 120 without falling into the lower part of the sphere 121.

The larvae transfer section 300 connects the larval individual separation unit 100 and the larval isolation culture unit 500 with the larvae individual separation unit 100 mounted thereon so as to separate separately separated megalopa larvae from the larval isolation culture To the isolation culture cuvette 510 of the unit 500.

Referring to FIGS. 1, 2, 7, and 8, the larvae sending section 300 includes a mounting platform 310 and a connection channel 330.

The mounting base 310 is configured in such a manner that the larvae individual separating unit 100 is inserted and mounted through the upper part, and is formed in the shape of a rectangular box which is opened at the top and one side.

On the bottom surface 311 of the mounting table 310, honey bean discharge ports 312 having the same shape as the honeycomb separator 121 are formed.

In the meantime, according to the present invention, when the larvae individual separation unit 100 is inserted into the mounting table 310, the larvae separate separation unit 100 is arranged such that the larvae outlet ports 312 and the larvae separation ports 121 are vertically aligned And a guide structure to be inserted and mounted in a fixed position of the mounting table 310 is provided.

The guide structures 315 and 118 are composed of a guide groove 315 and a guide protrusion 118. The guide grooves 315 are formed along the longitudinal direction at the middle portions of the three inner side walls 313 of the mounting table 310 and the guide protrusions 118 are formed on the outer circumferential surface of the frame member 310 except for the side wall 112, And is formed at an intermediate portion on the outer surface of the remaining three sidewalls 111, respectively.

When the larvae separate separation unit 100 is inserted into the upper part of the mounting table 310 with the above configuration, the guide protrusion 118 is guided in the guide groove 315 so that the larval individual separation unit 100 is mounted So that the larvae outlet ports 312 and the larvae separating ports 121 are vertically aligned with each other. As such, the guide arrangements 315 and 118 allow the operator to easily mount the larval individual separation unit 100 on the mounting platform 310 in place.

In addition, support bridges 317 are provided at four corners of the mounting base 310 so as to extend downward, thereby supporting the mounting base 310 at a predetermined height from the ground. This is to allow the operator to work on mounting or dismounting the larval individual separation unit 100 on the mounting platform 310 in a more comfortable posture.

The connection channel 330 is in the form of a flexible hose and includes a plurality of isolation channels 312 and a plurality of isolation culture vessels 510 one by one through a larval inlet 504 of the cover plate 503. [ .

1, 7 and 8, the larvae isolation culture unit 500 has a plurality of isolation culture vessels 510 and is connected to the larval isolation unit 100 through the larval transfer unit 300, And the larvae are supplied to the isolation culture cuvette (510), where they are separately isolated and cultivated to the cheek.

Specifically, the larval isolation culture unit 500 includes a culture water tank 501, a lid 503, and a plurality of isolation culture cans 510. [

The culture water tank 510 is in the form of a water tank in which water is received and the lid 503 is configured to cover the upper part of the culture water tank 510. The lid 503 is formed with a plurality of larval entrances 504 that correspond one to one with the nourishment outlets 312. The plurality of larval inlet ports 504 are configured to be coupled to the lower ends of the plurality of connection flow paths 330.

At this time, the upper end of each of the plurality of connection channels 330 may be formed in a honeycomb shape corresponding to the shape of the nourishment outlet 312, and the lower end may be formed in a circular shape corresponding to the shape of the larval inlet port 504 .

A plurality of isolation culture vessels (510) are formed in the same number as the larval entrance (504) and inserted into the culture water tank (510). At the top of each isolation culture cradle 510, each larva entrance 504 is positioned so as to correspond one-to-one. Accordingly, the plurality of connection channels 330 are configured to be connected in a one-to-one correspondence with the respective isolation culture cylinders 510.

Each of the isolation culture vessels 510 is formed in a cylindrical shape with an open upper part, and one megalopa larva can be cultured in the isolated culture vessel 510 in an isolated state.

Specifically, the isolation culture container 510 includes a culture body container 511 having a cylindrical shape with an open top and a bottom and having a through hole 512 through which water can flow into the container body 511, And the isolation culture vessel 510 is formed in a cylindrical shape with the upper part opened by the culture body vessel 511 and the blocking plate 514. As shown in FIG.

Here, the blocking plate 514 is configured to be folded or unfolded in half by the hinge means 517 (hinge). That is, one half of the blocking plate 514 is fixed to the inner circumferential surface of the culture body 511, and the other half is configured to be hinged by the hinge means 517. At this time, a part of the blocking plate 514 which is hinged by the hinge means 517 can be configured to be pivotable only in the upward direction without being rotated in the downward direction.

When the megalopa larva is cultured in the culture main body 511, dirt is formed in the culturing process. The operator puts his / her hand up from the lower part of the culture main body 511 to the upper part So that dirt formed on the upper portion of the blocking plate 514 can be removed.

1, the blocking plate 514 may be installed on the inner circumferential surface of the culture body 511, and the outer circumferential surface of the blocking plate 514 may be formed on the inner circumferential surface of the culture body 511, It is needless to say that the fixing ring 517 may be installed and the blocking plate 514 may be mounted on the upper portion of the fixing ring 517.

Best Mode for Carrying Out the Invention Hereinafter, with reference to the drawings, the use of a crab culture apparatus capable of individual culture according to an embodiment of the present invention will be described.

First, the operator causes the juvenile larvae, which are generated from eggs in the aquarium, to float on the top of the water tank (10) and grow into megalopa larvae while eating the floating food. Generally, the period of growth of Joea larvae as megalopa larvae is slightly different depending on the species, but about one week is enough.

When growing from Joea larvae to Megalopa larvae, they become heavy and can not float. The megalopa larvae are individually separated and isolated by the larval individual separation unit 100 located at the bottom of the water tank 10 while sinking downward.

Specifically, the megalopa larvae enter into the honeycomb type larvae 121 formed in the collecting plate 120 while being submerged, and are separated and isolated individually.

When the megalopa larvae c are individually separated into the larvae separation port 121 of the collection plate 120, the operator takes out the larvae individual separation unit 100 from the water tank 10, (310).

In this state, the one side wall 112 of the frame member 110 is opened and the valve plate 130 is pulled out of the lower insertion groove 115 of the frame member 110. 3, the megalopa larvae descend downward from the larvae separating port 121, and the larvae of the larvae of the larvae of the larvae of the larvae of the mounting base 311, which are aligned in a straight line, 312 into the isolation culture vessels 510 corresponding one to one through the respective connection channels 330 and the larval inlet port 504 and are accommodated one by one in the respective isolation culture vessels 510.

Thus, the megalopa larvae individually housed separately in each of the isolation culture vessels 510 can be separately cultured without being attacked from the surrounding people to the beef, and sufficient food can be supplied.

As described above, according to the present invention, by using the ecological habit of the megalopa larvae, that is, the habit of living on the bottom of the water tank, the larvae individual separation unit 100 is placed in the water tank 10 and the megalopa larvae (c) The individual megalopa larvae (c) are individually isolated from each other in each of the isolation culture vessels (510) contained in the culture water tank (501) through the larval feeding unit (300) By eliminating the cognate predation phenomenon attacking neighboring groups, it is possible to maximize the survival rate of crab cultured without crab dying, and to cultivate each crab into beef crab crab So that the production yield of the beater can be improved.

The annular separating unit 100 of the present invention may have a hooking hole 117 at the upper end of the side walls 111 and 112 of the frame member 110. The worker joins a hook (not shown) at the end of the string and hooks the hook (not shown) to the hooking hole 117 to pull the string, thereby pulling the larval individual separation unit 100, (10).

In addition, in the present invention, the larvae individual separation units 100 are stacked in the upper and lower stages in the water tank 10, when the megalopa larvae enter the upper larval individual separation unit 100, The individual separated uppermost larvae individual separation unit 100 is taken out of the water tank 10 and put into the isolation culture cask 510. After the operation, When the units are individually separated and accommodated, the lower larval individual separation unit 100 is taken out from the water tray 10 and put into the isolation culture bottle 510, so that the uppermost larval individual separation unit 100, To separate the juvenile separate separation unit 100 in order to increase the work efficiency.
