Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an artificial algae particularly suitable for use as an artificial reef and a method for producing the same.

Conventional artificial algae are relatively small, similar to sargassum and eelgrass, and have a poor attracting effect on fish, so they are unable to improve fishing efficiency, and they also play a role in spawning fish and protecting S-fish. I was also unable to fulfill my expectations.

On the other hand, conventional artificial reefs were constructed by sinking concrete blocks into the ocean floor, which required time and effort to construct, increasing construction costs.

The purpose of the present invention is to improve the effect of attracting fish and spawning of fish.

How effective is it to protect young fish? Sargassum to improve.

It has a large leaf structure similar to that of eelgrass intermittently, and can be easily and inexpensively produced.

Artificial reefs especially for the growth of fish with a wide distribution in the depth direction of the sea? An object of the present invention is to provide an artificial algae that can be easily produced and a method for producing the same.The artificial algae of the present invention achieves all of the above objects.

It is characterized by a plurality of synthetic resin tapes or synthetic fibers bundled together and fixed to the rope at desired intervals.

The manufacturing method of the present invention for producing all of the artificial algae is to arrange a large number of synthetic fibers with synthetic resin tapes along the rope, bundle and fix one synthetic resin tape or all the synthetic fibers at desired intervals, and fix these. This method is characterized by cutting the synthetic resin tape or synthetic fiber between the parts.

EMBODIMENT OF THE INVENTION Below, one embodiment of the present invention will be described in detail based on the drawings.

First, the artificial algae of the present invention will be explained. As shown in Figure 1, the middle part of multiple synthetic resin tapes (flat yarns) made of polypropylene, polyethylene, nylon, etc. whose specific gravity is lighter than 1 is attached to the rope 1 at desired intervals, and the ends are made of copper wire or synthetic resin. They are bundled and fixed in a tight state by a tool 3.

To make this artificial algae, attach polypropylene along both sides of the rope as shown in Figure 2A,B.

A large number of synthetic resin tapes (flat yarns) made of polyethylene, nylon, etc. having a specific gravity lighter than I are arranged in parallel.

Next, as shown in FIGS. 3j and 3B, the synthetic resin tapes are bundled at desired intervals and IE fittings 3 made of copper wire or synthetic resin are attached.
Fix it to the rope l in a tightened state. Next, as shown in FIG.
The artificial algae of the present invention shown in FIG. 1 by cutting like μ? Obtainable.

The artificial algae of the present invention constructed in this way.

A weight made of sandbags or the like is connected to one end of the rope.

A float 6 is connected to the other end of the rope l. As shown in Fig. 5, by installing the weight on the entire seabed 7, it is made to stand up in the depth direction from the rope/all floating body 7 to the sea surface, that is, the synthetic resin tape! It can be spread out in the form of dense lobes at desired intervals at desired depths from the entire ocean floor 7 to the bottom layer, middle layer, or sea surface. Is this an artificial reef by putting many fish in parallel?
You can also make multiple lobes/i one weight as shown in Figure 6! They can also be connected to form one large seaweed. Furthermore, as shown in FIG. 7, a large number of ropes/the entire floating body g can be hung down and used as a floating fish reef. Furthermore, as shown in FIG. 8, it can also be used in combination with an artificial reef of Φ made of concrete, reinforced plastic, etc.

Are there fish between the many leaf-shaped synthetic resin tabecos in any of the usage examples? It can be summarized, and especially in Figure 5,
In the usage examples shown in FIGS. 6 and 8, it is possible not only to collect fish but also to make them lay eggs in one synthetic resin tape, and also to preserve the fry by using the synthetic resin tape.

In particular, if the synthetic resin tape is cut at the middle part of the fixing part as in the above embodiment, the nine synthetic resin tapes will spread out in the radial direction from the center of the stopper 3, and an artificial rod having a large overall width t can be obtained. Furthermore, if a material that is easily resistant to diatom adhesion is used for the synthetic resin tape, the diatoms will be able to attract plankton and feed, thereby further improving the M4 attracting effect for fish.

1. If it is better for the leaves of the artificial algae to be more upright, foamed synthetic resin teflon may be used. Also, synthetic fibers may be used instead of the synthetic resin tape.

In this case, similar to the synthetic resin tape 1, a material that is easily resistant to adhesion of diatoms may be used. Furthermore, for the synthetic resin tape or synthetic fiber, colors similar to natural seaweed, such as green and beige, can be used. Further, the synthetic resin tape or the synthetic fibers may be cut near the fixing portion, and the fixing means may be tightening or welding force sound. Furthermore, one piece of synthetic resin tape or synthetic fibers may be arranged in parallel all around the rope 1 or in a part thereof. Furthermore, according to the present invention, it can be installed not only in artificial fish reefs but also in aquaculture cages.As is clear from the above description, according to the present invention.

Since a large number of synthetic resin tapes or parts of synthetic fibers are bundled and fixed at desired intervals to the pop-up, large-sized products with intermittent leaf-like parts similar to sargassum and eelgrass can be produced with a simple structure. Since the manufacturing method is simple, it can be provided at low cost. In addition, the leaf-like portions can be provided over a wide distribution in the depth direction of the sea.

If it is used as an artificial reef, it can improve the fish attracting effect, fish spawning, protection efficiency, etc. by 9%.

It has the advantage of being easy to transport and reducing construction costs.
