Definitions
- the present invention relates to a fish repellent that keeps fish from approaching a specific location, and a seaweed cultivation method using the same.
- seaweed feeding damage is closely linked to the rise in seawater temperature.
- fish such as Aigo and black sea bream, which should be inactive in the cold season, move around actively even in winter and eat seaweed during aquaculture.
- seaweed farms in various regions are trying various measures to prevent fish from approaching the seaweed nets (so-called seaweed nets).
- seaweed nets seaweed nets
- Patent Document 1 describes a device for keeping fish away from the aquaculture net by submerging the speaker in the sea and emitting sound from the speaker.
- a speaker underwater speaker
- power is required to operate the speaker. Therefore, it is necessary to connect the land and the sea with an electric cable, or install a power generation device and a battery on the sea. In the first place, there are doubts about how much fish can be repelled by sound.

It is also an object of the present invention to provide a seaweed cultivation method using this fish repellent.
- a fish repellent that repels fish A menacing band-shaped member that threatens fish by swaying in the water This is solved by providing a fish repellent that is characterized by providing a hanging member for supporting the threatening band-shaped member in a state of being suspended from the vicinity of the water surface in the water.
- the fish repellent of the present invention When the fish repellent of the present invention is installed, the threatening band-shaped member suspended in the water will sway in the water due to the water flow (tide, river flow, etc.). Therefore, it is possible to surprise the fish by the movement of the threatening band-shaped member and keep it away from the fish repellent.
- the fish repellent device of the present invention has a very simple structure composed of a threatening band-shaped member and a hanging member. Therefore, the fish repellent of the present invention is not only inexpensive, but also has no risk of failure. Further, the fish repellent device of the present invention can be constructed by a simple operation of attaching a hanging member to a predetermined position.
- the material of the threatening band-shaped member is not particularly limited as long as it is a band-shaped member having a certain length.
- the threatening band-shaped member is formed of a soft member, the threatening band-shaped member may be entangled or entangled with other members.
- the threatening band-shaped member is formed of a hard member, the threatening band-shaped member that sways in water only moves monotonously, and the threatening effect may not be easily achieved. Therefore, the threatening band-shaped member is preferably formed of a member that is rigid but has bending elasticity. Examples of such a member include a metal plate formed in a band shape.
- the surface of the threatening band-shaped member may have a non-glossy finish, but it is preferable that the surface has a glossy finish.
- the threatening band-shaped member can be made conspicuous. Therefore, it becomes easier for fish to recognize the existence of the threatening band-shaped member, and the threatening effect on fish can be further enhanced.
- the fish repellent of the present invention can be installed in any place as long as it is in a water area (sea, river, swamp lake, etc.) where fish are present.
- the fish repellent of the present invention can be used.
- it can be suitably used when culturing fish and shellfish, particularly when culturing seaweed such as seaweed and wakame seaweed, and particularly preferably when culturing seaweed. can.

- [1] Float the frame (float frame) to which the float (float) is attached to the sea, and lower the anchor from the float frame to prevent the float frame from being washed away, and multiple ropes (float rope) inside the float frame.
- a method called “floating fishing method” in which a culture net (seaweed net) is stretched between the float rope and the float rope.
- post fence fishing method in which a plurality of stanchions are erected in a fence shape in the sea and aquaculture nets (nori nets) are laid between the stanchions.
- the fish repellent of the present invention can be adopted by either the floating fishing method of the above [1] or the support fence fishing method of the above [2], but in the following, for convenience of explanation, it is used in the floating fishing method.
- the fish repellent device of the present invention will be described by taking a case as an example.
- FIG. 1 is a diagram showing a state in which seaweed is cultivated (floating fishing method) using the fish repellent tool 10 of the present invention.
- the float frame 20 is arranged in a frame shape so as to surround the seaweed farm.
- a plurality of floats 21 are attached to the float frame 20 at predetermined intervals. Therefore, the float frame 20 is designed to maintain a state of floating on the sea surface.
- Anchor 30 is lowered from the vicinity of the float 21 to prevent the float frame 20 from being washed away by a tidal current or the like.
- the float frame 20 is arranged in a frame shape, and a plurality of float ropes 40 are stretched in parallel at intervals of about 3 m inside the float frame 20.
- Small floats 41 are also attached to the float rope 40 at predetermined intervals so that the float rope 40 does not sink into the sea.
- Suspension ropes 50 are attached to each float rope 40 at intervals of about 2.5 m.
- the tip end side of the suspension rope 50 is connected to the side edge of the aquaculture net 60 (nori net). Therefore, the aquaculture net 60 is in a state of being pulled to the opposite side by the hanging ropes 50 arranged on both sides in the lateral direction. Therefore, the aquaculture net 60 is kept stretched in the space between the adjacent floats 40.
- the aquaculture net 60 has a long strip shape and is arranged so as to be parallel to the tide flow F. Therefore, the float rope 40 is also provided in parallel with the tide flow F. This makes it possible not only to efficiently carry out the work of stretching and collecting the aquaculture net 60 by utilizing the flow of the tide, but also to efficiently propagate the seaweed on the aquaculture net 60.
- the dimensions of each aquaculture net 60 are not particularly limited. In this embodiment, a culture net 60 having a width of 1.6 m and a length of 20 m is used. By arranging two aquaculture nets 60 of this size in the direction of the tide flow F, the aquaculture nets 60 are arranged over a range of 40 m in length in each row.

- the threatening band-shaped member 11 in the fish repellent 10 receives the tide flow F and sways in the direction of the tide flow F. Therefore, it is possible to intimidate fish by the movement of the intimidating band-shaped member 11.
- the float rope 40 is located on both sides of each of the aquaculture nets 60 in the lateral direction, and a plurality of fish repellents 10 are attached to each of the float ropes 40 on both sides at predetermined intervals. Therefore, rows of fish repellents 10 are formed on both sides of each aquaculture net 60 in the lateral direction. Therefore, even if a fish tries to prey on the seaweed that is breeding in the aquaculture net 60, one of the fish repellents 10 gets into the eyes and cannot approach the aquaculture net 60.
- the interval S (FIG. 1) at which the fish repellent 10 is arranged also differs depending on the length L (FIG. 2) of the threatening band-shaped member 11 and the like.
- the interval S between the fish repellents 10 is made too narrow, the number of fish repellents 10 required increases. Further, the load applied to each float rope 40 becomes large, and it may be necessary to take measures such as making the float rope 40 thicker or increasing the number of floats 41. Further, the threatening band-shaped member 11 of the adjacent fish repellent 10 may be easily entangled. Therefore, the interval S of the fish repellents 10 is preferably set in a range in which the ratio S / L to the length L of the threatening band-shaped member 11 is 0.5 or more.
- the ratio S / L is more preferably 1 or more, and further preferably 1.5 or more.
