BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a floating and sinking cage for aquaculture and temporary detention of fish in the ocean, in the sea or in the water.

[0002]

2. Description of the Related Art A conventional cage has a structure in which a cage net whose entire surface is surrounded by a net is moored to a required depth in the sea or underwater by using a floating float, an anchor and a rope. When feeding fish to fish in the cage net or harvesting fish, air is injected into the air float attached to the cage net to raise the cage net, and then the feeding of fish and the harvesting of fish are performed. When installing the cage net in the sea or underwater, bleed the air from the air float so that it stays at the required depth. At this time, the depth of the seawater to be installed is appropriately determined according to the state of seawater such as fish, weather, wave tide, seawater temperature, red tide, and the like.

[0003]

[Problems to be solved by the invention] The conventional floating and floating cage
If the sea float oscillates due to waves, the nets moored by the sea floats and ropes will be transmitted as they are and will sway in the sea, causing the nets to break and the facilities to be damaged, causing the fish to escape. Moreover, even if there was no damage, the outer shape of the net collapsed and the net contacted the fish, damaging the fish. Also, the actual exploitation 54
-57200 discloses that a floating float and a cage net are connected.
A pulley is connected to the rope to be connected, and the pulley is connected to a wire of a certain length.
There is also a technique to moor the anchor with, but using this technique
However, the sway of the float on the sea is still a net through the pulley.
To maintain its shape retention by suppressing its up-and-down sway transmitted to the
It was something that could not be done. The problem to be solved by the present invention is to solve these conventional problems, to suppress the shaking of the cage net, reduce the damage to the net and the facility, and reduce the damage to the fish. To provide.

[0004]

[Means for Solving the Problems] The gist of the present invention, which has solved the above problems, is to install a floating and floating air float on the upper part and to arrange a cage net surrounded by a net in the sea. In the float-sink type cage in which the float and the anchor are connected by a rope to form a mooring body, and the mooring body and the cage net are linked by a connecting rope to moorize the cage net at a predetermined depth in the sea. Attach a weight in the middle of the connecting rope ,
Moreover, the connecting rope is bent at the point of weight with few waves
It is a floating and floating cage that is stretched so that Here, the net material of the fish cage net of the present invention may be any fish net, plastic net, wire net, or synthetic fiber net in which a rope is woven.

[0005]

According to the present invention, the cage net is moored to the mooring body composed of the sea float and the anchor and the rope connecting them, and the weight is attached to the middle of the rope. Therefore, when the number of waves is small, the middle of the connecting rope is sunk by the weight, and the rope is pulled so as to be broken from the position of the weight. Therefore, even if the sea float is lifted upwards or moved horizontally,
First, the position of the weight moves so that the connecting rope becomes straight from the fold line, and the rise of the maritime float and the amount of movement in the front, rear, left, and right are the play amount and the weight of the difference between the fold line state and the straight state of the connecting rope. It is absorbed by the energy decay associated with the movement of the fish, and the shaking of the cage net is reduced. The cage net is less swaying due to waves and tidal currents and has good shape retention. It protects the cage net itself and reduces the contact between the fish inside and the cage net to prevent fish damage.

Embodiments of the present invention will be described below with reference to the drawings. 1 is a front view of the embodiment, FIG. 2 is a plan view of the embodiment,
FIG. 3 is an explanatory view showing a main part of the embodiment, and FIG. 4 is an enlarged plan view of a cage net of the embodiment.

[0007] In the figure, 1 is a cubic plastic cage net of 8 m x 8 m x 8 m, 2 is a floating and sinking type air float attached to the upper part of the cage net, 3 is an anchor, 4 is a sea float,
5 is a rope, 6 is a mooring body, 7 is a connecting rope of about 8 m mooring the cage net 1 to the mooring body 6, 8 is a weight of 8 kg provided in the middle of the connecting rope, 9 is a tensioning rope of the mooring body 6, 10
Is an air tube for injecting and discharging the air of a floating air float, 11 is a float, 12 is a double wapper, 13 is the sea surface,
14 is the seabed.

In this embodiment, the cage net 1 is installed about 7 m below the sea level. The mooring body 6 arranges the air float 2 at each corner of a 20m square, and 20m x 20m 2m below the sea level.
The rope 5 is linked to the anchor 3 so as to form a tension rope 9 of m. The cage net 1 is moored by a connecting rope 7 8 m from the double wappers 12 at the corners of a tension rope 9 stretched in a square shape. In this embodiment, even if a strong wave is generated on the sea surface and the air float 2 moves up and down along with the sea surface, only the bent state of the connecting rope 7 changes as shown in FIG. The binding point with and does not change significantly, and there is little sway of the cage net 1. This is because the weight 8 causes the connecting rope 7 to be bent in the middle, and the deformation of the connecting rope 7 gives play to the mooring length of the connecting rope 7 and the force and energy of the air float 2 to move the weight 8. Is to be used. Even if the sea surface is 3 to 4 meters long, the net movement of the cage net is about 40 cm.
The shaking is much less than the shaking of ~ 4m. Also, the cage net 1
It does not lose its shape.

[0009]

As described above, according to the present invention, by providing a weight in the middle of the connecting rope, the shaking of the cage net and the collapse of the net shape can be suppressed to a fraction or less of the conventional one. . As a result, there was no damage to the nets and facilities, less contact with fish nets, and less damage to the fish.
