DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a culture basket used for culturing scallops, oysters, pearls, shellfish such as abalone, sea urchins and the like.

[0002]

2. Description of the Related Art Conventionally, as an example of this kind of aquaculture basket,
A so-called Zabton cage, which is made of synthetic fiber netting outside the support frame consisting of a square outer frame and a reinforcing bar connected between opposing sides of the outer frame and crossed in a cross shape. ,
An outer enclosure (mesh bag) whose upper part is a quadrangular pyramid is provided, a bottom surface of the outer enclosure is attached to a support frame, and an openable and slittable slit formed along one of the ridges of the outer pyramidal part. A closing thread is inserted into the mesh of both side edges of the loading / unloading part so that it can be opened and closed, and a hanging rope is connected to the center of the intersection of the reinforcing bar of the support frame and the bottom of the outer circumference. A configuration is known in which the upper portion of the hanging rope is inserted through the top of the quadrangular pyramid and connected at the top.

[0003] In order to use the cultured cage constructed as described above, a closing thread is inserted in a mesh on both side edges of the surrounding input / discharge section so as to be wrapped and closed. The distal end of the funnel is inserted into the section, and a desired number of scallops and the like are put into the surroundings using the funnel. Then, the farming basket is sunk in the sea together with scallops, etc., and the hanging rope is connected to a raft moored on the sea, and it is supported in a state where it is sunk in the sea by a slant attached to the lower end of the hanging rope. Foster scallops, etc. After cultivation for a desired period of time, raise the culture cage from the sea to the ship or land, remove the closing thread, release the input / output unit, and fold the culture cage with the input / output unit facing down. Is shaken to open the loading / unloading section by the weight of the scallops and the like and drop the scallops and the like. Thereafter, the desired number of scallops and the like are dispersed and thrown into a culture basket having a larger mesh size than the above to grow them.

[0004] As another example of the conventional culture basket, a so-called round basket, which is provided in a plurality of stages, includes a circular outer frame, and a reinforcing bar crossed and connected to the outer frame in a cross shape. The outer frame made of synthetic fiber netting is attached to the outside of the support frame, and the shelves made of synthetic fiber netting are attached to the support frames of each step to form a multi-stage storage room, and the outer shell is formed. The insertion / ejection section consisting of a butt-shaped vertical split corresponding to each storage room is formed in the section, and it can be opened by inserting a closed thread into the mesh on both side edges of the entry / exit section. There is known a configuration in which a suspension rope is connected to a plurality of closed outer peripheral portions of a support frame.

[0005] In order to use the multi-stage cultured basket constructed as described above, for example, during culturing, semi-adult shellfish is put into the storage chamber from the loading / unloading section, and the mesh near the loading / unloading section is closed. Sewing with and close the input / output section. Then, the farming basket is submerged in the sea together with the semi-adult shellfish, and the suspension rope is connected to a raft moored on the sea for farming. After cultivation for a predetermined period, removal for thinning in the next process, intermediate breeding, for example, ear hanging cultivation, transfer to a coarse cultivation cage, or removal for shipping after cultivation, the multistage culture cage Raise on board or on land. Then, the closing thread is removed, the loading / unloading section is opened, the multi-stage culture cage is turned sideways, and both ends of the hanging rope are held by two workers in total, and the multi-stage culture cage is rocked up and down. As a result, the loading / unloading section is opened and dropped by the weight of the shellfish.

[0006]

The cultivation basket is submerged in the sea, and the cultivation target is cultivated for one to six months. During the cultivation, marine organisms such as mussels, barnacles, polydras, starfish, and seaweed cover the entire surroundings. Adheres in large quantities. For this reason, as described above, when the farming target is transferred to another farming cage or when the farming cage is lifted from the sea to the ship or land for the purpose of landing, it is difficult to identify the input / output part, Takes time. Further, even if the input / output unit can be identified, if the input / output unit is blocked by seaweed, it takes time to release the input / output unit by cutting, removing, etc. the seaweed. .

[0007] By the way, it can be said that it is a good environment for an aquaculture object to work in which the aquaculture object is cultivated in the sea, pulled up on a ship or land, transferred to another aquaculture basket, and then re-entered into the sea. Instead, it must be done in as short a time as possible. In addition, it is required that the loading / discharging unit be released in as short a time as possible in order to maintain freshness even when landing the aquaculture.

However, as described above, in the conventional aquaculture cage, the input / discharge unit is released when it is difficult to identify the input / discharge unit when it is lifted from the sea to a ship or land after a certain cultivation period has elapsed. This takes time, damaging the aquaculture target and hindering subsequent growth. Further, when the aquaculture target is landed, freshness cannot be maintained, and the commercial value may be reduced.

[0009] Further, in cultivating shellfish and the like, the shellfish and the like are sequentially transferred to a large-sized fish culture basket as the shellfish and the like grow, so that the mesh size is conventionally 3 mm, 3.6, for example.
Cultured baskets having different stages, such as 4.5 mm, 4.5 mm, 6 mm, 7.5 mm, and 9 mm, are used. Regardless of the size of the fish cage,
From the viewpoint of manufacturing cost, for example, Russell netting uses a unified blue netting, while frogs and knotted netting uses a black netting. For this reason, it is possible to relatively easily identify the culture cages having different mesh sizes even if the same color of mesh yarn is used, but the mesh sizes are close to each other. It is difficult to discriminate between farmed cages that the same color of mesh yarn is used, which is confusing at the time of storage and use, which is one factor that cannot rationalize the farming work.

[0010] The present invention is to solve the above-mentioned conventional problems, and it is possible to easily and quickly set up the input / output section when a certain aquaculture period elapses and then the ship is unloaded from the sea to a ship or land. Can be quickly released and the cultivated object can be discharged quickly, so that when the cultivated object is relocated, it can grow well thereafter, and when it is landed, It is an object of the present invention to provide a farming cage that can maintain freshness and enhance commercial value.

Further, in addition to the above-mentioned objects, the present invention provides a method for storing and using a digital camera so that it can be relatively easily identified even when an outer periphery having a close difference in mesh size is used. It is an object of the present invention to provide an aquaculture car that can prevent confusion and can therefore contribute to streamlining aquaculture work at low cost.

[0012]

In order to solve the above-mentioned problems, a culture basket according to the present invention is formed in an outer periphery made of a net-like material, and is used for identifying an input / discharge section for inputting or discharging an object to be cultured. Is applied.

[0013] In the above configuration, as the identification means, an identification color can be applied to the mesh of the input / output unit, or an identification color can be applied to a position sandwiching the input / output unit.

In order to solve the above-mentioned problems, another culturing car according to the present invention is such that in any one of the culturing cars described above, the identification means can be used also for identifying the size of the mesh of the mesh material constituting the outer periphery. It is constituted in.

According to the present invention configured as described above,
Even if the surrounding area is covered with marine organisms when it is lifted from the sea to a ship or land after a certain period of cultivation, the input and output parts can be easily and quickly identified by the identification means. -The discharge part can be quickly released from marine organisms and the aquaculture target can be discharged quickly.

Further, even if the difference in the size of the meshes forming the outer periphery is close, the identification means can identify them relatively easily, so that confusion during storage and use can be prevented.

[0017]

Embodiments of the present invention will be described below with reference to the drawings. First, a first embodiment of the present invention will be described. 1 and 2 show a culture cage according to a first embodiment of the present invention. FIG. 1 is a perspective view showing a state where an input / output unit is closed, and FIG. 2 is a perspective view showing a state where an input / output unit is opened. It is.

The farmed car according to the present embodiment is called a so-called Zabton car. As shown in FIGS. 1 and 2, the support frame 1 includes a square outer frame 2 and a reinforcing bar 3. The reinforcing bars 3 are crossed in a cross shape, and each reinforcing bar 3 is connected between the intermediate portions of the opposite sides of the outer frame 2 by hook-shaped portions at both ends. Outside the support frame 1, a fence or knotted net made of synthetic fibers or the like, a Russell net, or the like is provided, and an outer frame (mesh bag) 4 having a quadrangular pyramid-shaped upper portion is provided. Four bottoms are attached. A slit-shaped input / output unit 5 is formed to be openable and closable along any ridge of the quadrangular pyramid-shaped portion of the outer enclosure 4. The closing thread 6 is inserted through the meshes at both side edges of the loading / unloading section 5 so as to hang over it, and the loading / unloading section 5 is closed so as to be openable.

The input / output unit 5 has the following
The color that can be distinguished from other parts is given. For example, when the main body of the outer enclosure 4 is formed of a black net, the edge 7 of the input / output unit 5 is formed of a brown net with a width indicated by a chain line. When the section is made of a blue netting, the edge 7 of the input / output section 5
Is made of green net yarn with a width indicated by a chain line, and the edge 7 of the input / output unit 5 is identified by a color different from that of the main unit.

A suspending rope 8 is connected to a central crossing portion of the reinforcing bar 3 and a central portion of the bottom of the outer enclosure 4. The suspending rope 8 is connected to a top of the outer enclosure 4 and is inserted upward. The culture cages are used by being attached to the hanging ropes 8 at desired intervals in a plurality of stages as needed.

In order to use the cultured basket constructed as described above, as shown in FIG. 1, the closing thread 6 is inserted into the mesh on both side edges of the input / output section 5 of the outer envelope 4 so as to hang it. And close it, and insert the tip of the funnel into a part of the
Using this funnel, a desired number of scallops and the like are put into the outer enclosure 4. Then, the culture cage is submerged in the sea together with the scallops and the like, and the hanging rope 8 is connected to a raft moored on the sea, and is supported in a state of being submerged in the sea by a sediment attached to the lower end of the hanging rope 8. Raise scallops in the condition. After cultivation for a desired period, the culture cage is lifted from the sea to a ship or land. At this time, the entire outer envelope 4 is covered with the marine organisms attached thereto, but the input / output unit 5 is provided with a different color for identification from the main unit, so that it is easy and quick. Therefore, the marine organisms attached to the vicinity of the input / output unit 5 can be quickly and preferentially removed, and the input / output unit 5 can be released. After that, the closing thread 6 is pulled out to release the loading / discharging section 5, and the farming basket is shaken in a state where the loading / discharging section 5 is turned down, and the farming basket is shaken and thrown in by its own weight such as scallops. The discharge part 5 is opened to drop the scallops and the like.
Thereafter, the desired number of scallops and the like are dispersed and thrown into a culture basket having a larger mesh size than the above to grow them.

The above-mentioned identification means merely identifies the position of the loading / unloading section 5. In addition to this, as a mesh forming the outer envelope 4, for example, a mesh having a size of 3 mm, 3.
6mm, 4.5mm, 6mm, 7.5mm, 9mm, etc.
When a plurality of kinds of cultured cages that change stepwise are used in accordance with the growth of shellfish or the like and used, the cultured cages can be distinguished from each other. For example, the mesh size is 3 mm, 3.6 mm, 4.
In the case where the main body is made of a blue net yarn with an outer circumference 4 of 5 mm, 6 mm, 7.5 mm, and 9 mm, the edge 7 of the input / output unit 5 has a width indicated by a chain line, and is yellow, green, It is composed of orange, yellow, green, and orange nets. In this way, by changing the color of the edge 7 of the input / output unit 5 of the culture cage in which the difference in mesh size is at least close to each other, it is possible to reduce the types of colors and discriminate them from each other at low cost. However, the colors of the edges 7 of the input / output unit 5 may be changed for each of the cultured cages having different mesh sizes.

By providing such identification means with different colors, it is possible to relatively easily identify even if the difference in the size of the meshes constituting the outer envelope 4 is close. Time confusion can be prevented. Then, by using the net yarn partially different in color, they can be distinguished from each other, so that the cost can be increased.

Next, a second embodiment of the present invention will be described. 3 to 5 show a culture basket according to a second embodiment of the present invention. FIG. 3 is a perspective view showing a state where an input / output unit is closed, and FIG. 4 is a perspective view showing a state where an input / output unit is opened. ,

A circular shelf 19 made of netting such as synthetic fibers is attached to and supported by the support frame 11 in the body 15 on the support frame 11 of each step at the intermediate portion. Thereby, a storage room 20 for aquaculture is formed between the support frames 11 and 11.

A slit-shaped charging / discharging portion 21 is formed in the body portion 15 of the outer periphery 18 so as to open and close each storage chamber 20 along the axial direction. The closing thread 22 is inserted into the mesh at both side edges of the input / output unit 21 so as to hang over the mesh.
The charging / discharging section 21 is openably closed. Input
The discharge unit 21 is given a color that can be distinguished from other parts as its identification means. For example, when the main body of the outer periphery 18 is formed of a black mesh thread, the edge 23 of the input / output unit 21 is indicated by a chain line in FIGS. 3 and 4 and is indicated by a thick solid line in FIG. It is composed of brown net yarn in width. In the illustrated example, the outer enclosure 18 is formed of a frog or a knotted net, but may be formed of, for example, a Russell net.

At the connection between the outer frame 12 and the reinforcing bar 13 in the support frame 11 of each stage, the middle part of the suspension rope 24 is connected, and the upper and lower projections of the plurality of suspension ropes 24 are respectively It is bundled substantially on the center line of the support frame 11. A weight (not shown) is connected to the lower end of the hanging rope 24 as necessary.

In order to use the multi-stage cultured basket constructed as described above, for example, semi-adult shellfish is charged into the storage chamber 20 from the input / discharge unit during culture, and the mesh near the input / discharge unit 21 is used. Is closed with a thread 22 and the input / output unit 21 is closed.
Then, the culture cage is submerged in the sea together with the semi-adult shellfish and the like, and the suspension rope 24 is connected to a raft moored on the sea for aquaculture.
After cultivation for a predetermined period, removal for thinning in the next step, intermediate breeding, for example, ear cultivation, transfer to a rough cultivation basket, or removal for shipping after cultivation, cultivation baskets from the sea Raise on board or on land. At this time, the entire outer envelope 18 is covered with the attached state of marine organisms. However, since the input / output unit 21 is given a different color for identification from the main unit, it is easy and quick. Can be identified, and therefore the input / output unit 2
1 can be quickly and preferentially removed from the marine creatures attached to the vicinity 1 to open the input / output unit 21. afterwards,
The closing thread 22 is removed to put the charging / discharging section 21 in an open state,
The multi-stage culture cage is turned sideways, and the two ends of the hanging rope 24 are held by two separate workers, and the input / output unit is opened and dropped by swinging the multi-stage culture cage up and down.

Next, a third embodiment of the present invention will be described. FIG. 6 is a partially enlarged view showing a culture cage according to the third embodiment of the present invention.

In the present embodiment, door pieces 25 and 26 following the outer periphery 18 are provided so as to overlap as the loading / unloading section 21 of the continuous culture cage according to the second embodiment. The door pieces 25 and 26 are opened in a double-opening manner by inserting a closing thread (not shown) through the opening, and a large opening is formed to make it easier to insert shellfish or the like, or to facilitate discharging. Things. In the present embodiment, the width 27 indicated by a thick solid line is applied to the door piece 26 overlapping outside as a means for identifying the input / output unit 21.
In the color of the mesh of the other part, for example, a net yarn of a color different from blue,
For example, a green net yarn is used. Other configurations are the same as those of the second embodiment. In addition,
In the illustrated example, the outer periphery 18 and the door pieces 25 and 26 are made of Russell netting, but may be made of, for example, frogs or knotted netting.

In the above-described so-called round basket, the charging / discharging section 21 is identified by using blue for the hanging rope 24 at the position sandwiching the charging / discharging section 21 and using black for the other hanging ropes 24. You can also. By using such an identification means, there is no possibility that the entire length of the hanging rope 24 will be covered by marine organisms, so that the input / output unit 21 can be identified even more simply and quickly.

In the culturing cage according to the second and third embodiments, similarly to the culturing cage according to the first embodiment, the edge 23, the width 27, and the hanging rope 24 of the loading / unloading section 21 are provided. By using a mesh thread and a hanging rope 24 of a different color from that of the fish cage of other sizes, it is relatively easy to identify, and it is possible to prevent confusion during storage and use, Further, it is possible to prevent the cost from increasing.

The present invention is not limited to the above-described embodiment. For example, the charging / discharging section 5 in the first embodiment is not limited to a slit shape, and may be a sheet having both side edges overlapped and bent. In addition, the present invention can be variously changed in design without departing from the basic technical idea.

[0034]

As described above, according to the present invention, even if the surrounding area is covered with marine organisms when it is lifted from the sea to a ship or land after a certain period of cultivation, it can be input and discharged by the identification means. Since the parts can be easily and quickly identified, the input / discharge part can be quickly released from marine organisms, and the aquaculture target can be discharged quickly. Therefore, when the aquaculture target is transferred, it can be satisfactorily grown thereafter, and at the time of landing, freshness can be maintained and the commercial value can be increased.

In addition, since the identification means can identify the difference in the size of the meshes forming the outer periphery, the identification means can relatively easily identify even if the difference in the mesh size is close. Therefore, confusion during storage and use can be prevented, and therefore, it is possible to contribute to the rationalization of aquaculture work at low cost.
