Abstract

PROBLEM TO BE SOLVED: To provide a rope capable of cultivating seaweeds and sea algae at a low cost without polluting and the bottom of a sea or a lake. SOLUTION: This cultivating rope, an eelgrass-breeding rope 12 in cultivating eelgrass, comprises a rope 14 composed of a biodegradable material and eelgrass seeds 16 inserted into the rope 14. The biodegradable material is degraded with time and returns to nature such as soil, and straw is used as such biodegradable material and the rope 14 is a straw rope. The eelgrass seeds 16 may be inserted into the rope 14 when the rope 14 is twisted or may be manually inserted into the rope 14 after the rope 14 is completed, so the insertion work can be freely performed.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to seagrass such as eelgrass, small eelgrass and shrimp, seaweed, kelp,
The present invention relates to a class for growing seaweeds and seaweeds suitable for growing seaweeds such as alame.

[0002]

2. Description of the Related Art In recent years, the seas and lakes have been polluted, and seaweeds and seaweeds are in danger of becoming extinct. A variety of organisms inhabit where seaweeds and seaweeds grow, and fish gather to eat them. Seagrass and seaweeds play an important role in controlling the marine ecosystem. Therefore, it is necessary to forcibly grow seagrass and seaweed in places where seaweeds and seaweeds are likely to become extinct or have disappeared. Conventionally, as a method of growing seaweeds and seaweeds, a sheet made of a biodegradable material and a synthetic resin is used.For example, after growing seagrass eelgrass, the sheet is laid on the seabed. Have been done.

[0003]

However, in such a method, since a sheet is used, when laying the sheet on the seabed, it is necessary to use a large work boat instead of a fishing boat.
There is a problem that the cost increases. In addition, since the sheet contains a synthetic resin, the synthetic resin remains on the seabed, which also contributes to soiling the seabed. The present invention has been devised in view of the above circumstances, and an object of the present invention is to provide a seaweed and a seaweed growth rope capable of growing seaweeds and seaweeds at low cost without polluting the seabed or lake bottom. It is in.

[0004]

In order to achieve the above object, the present invention provides a class for growing seaweeds and seaweeds comprising a class composed of a biodegradable material, and a seagrass or seaweed inserted into the class. And a large number of species. Further, the growth class of seaweeds and seaweeds of the present invention is a class composed of biodegradable materials, and a large number of seagrass or seaweeds that germinate from the species inserted into the class and grow leaves from the class. And characterized by the following. In the present invention, seaweeds and seaweeds are grown by laying a rope on the seabed or lake bottom. In this case, the ropes are composed of biodegradable materials, and the ropes can be easily laid on the seabed or lake bottom by ordinary fishing boats. Can grow.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention applied to growing seagrass eelgrass will be described below with reference to the drawings. FIG. 1A is a cross-sectional view of the eelgrass growing line, and FIG. 1B is a front view of a part of the eelgrass growing line. The eelgrass growing line 12 according to the embodiment (corresponding to the growing line for seaweeds and seaweeds in the claims) includes a class 14 composed of a biodegradable material, and a large number of eelgrass inserted into the class 14. And 16 of the above. Biodegradable materials are degraded over time and return to nature such as soil.For example, such biodegradable materials include natural materials such as straw, hemp, cotton, and biodegradable plastics. Can be used. In addition, it is desirable to use a natural material such as straw, hemp, or cotton as the biodegradable material from the viewpoint of global environmental protection. In the present embodiment, straw is used, and the rope 14 is a rough rope. The eelgrass seed 16 may be inserted into the rope 14 when the rope 14 is twisted, or may be manually inserted into the rope 14 after the rope 14 is completed. The insertion method is arbitrary.

Next, a method for growing eelgrass using the eelgrass rope 12 will be described. First, as shown in FIG. 2 (A), the eelgrass growing line 12 is placed in a water tank 18 and the water temperature is changed several times between, for example, about 15 ° C. and about 8 ° C. Germinate by giving. As a result, as shown in FIG. 2B, the eelgrass seeds 16 inserted into the rope 14 germinate, and a large number of leaves 1602 grow from the rope 14. Next, when the leaves 1602 have been appropriately grown, as shown in FIG. 3, the eelgrass growing line 12 is laid on the seabed or the bottom of the lake, and the anchor 20 or the like is attached to the seabed or the lake at appropriate lengths. Avoid being washed away.
As a result, the eelgrass grows on the rope 14 and eventually breeds on the surrounding seabed or lakebed.

According to the present embodiment, the eelgrass growing line 1
2 is simply a grassy rope, takes up little space and requires no special equipment, and can therefore be easily laid on the sea floor or lake bottom with a normal fishing boat. Further, since the rope 14 constituting the eelgrass growing rope 12 is entirely composed of a biodegradable material, there is no problem of polluting the seabed, such as a case where a synthetic resin remains on the seabed or lake bottom later as in the related art. .

[0008] In the above embodiment, seagrass, eelgrass, has been described as an example.
It is widely applied when growing seaweeds such as small eelgrass and shrimp, and seaweeds such as seaweed, kelp, and alame.

[0009]

As described above, according to the present invention, seaweeds and seaweeds can be grown at low cost without polluting the seabed or lake bottom.
