Description

  More particularly, the present invention relates to a method for cultivating a black-crowned owl and a cultivating net that enables high-density culturing by developing the cultivating net vertically by floating and weight.

Sea bream, seaweed, oysters, etc. are cultivated in inner bays and bays where the waves are quiet to fix the nets and ropes used for aquaculture.
On the other hand, there is a problem that it is difficult to secure income in the winter season because it is difficult to secure suitable farming areas throughout the year because the waves are rough in the open sea, and fishing boats cannot be operated at the time of shike, which increases in winter. For this reason, local fishermen are demanding the development of new aquaculture varieties that are possible in the open sea as a countermeasure for the winter fishing season.
In view of such a situation, the applicant of the present application has previously filed Japanese Patent Application Laid-Open No. 2001-57823 as a technique relating to the cultivation of foxtail.
JP 2001-57823 A

The mosquito is a marine alga belonging to the brown alga Nagamatsumo, and grows in reefs and boulders with relatively rough water depths of 2 to 5 m. The fishing season is only one month from late April to late May. Although it is currently collected mainly by Ama, its production is extremely small and it is a rare algae.
Conventionally, in the cultivation of seaweed, there have been adopted a support system in which a laver net is fixed to a compost standing on the seabed or a support such as bamboo, and a floating system in which the net is stretched horizontally on the sea surface. As shown in FIG. 5, this floating method is a method in which a net made of synthetic fiber strands having a mesh size of about 30 cm is connected to a support in the sea and spread in the horizontal direction.
However, in order to install an aquaculture net on the seabed, an operator must dive at the time of the net installation, aquaculture management and harvesting in order to install the aquaculture net on the bottom of the sea. Therefore, labor and cost are required.
In addition, in order to stretch the net in the horizontal direction, a large installation space is required, and considering the nature of the foxtail that grows on rocky reefs and boulders, there is a problem that the installation is extremely difficult.
The present invention has been made to solve the conventional problems, and the object of the present invention is to make it possible to easily arrange the aquaculture net in the vertical direction by attaching a float and a weight to the net. It is an object of the present invention to provide a method for cultivating a wolf mozuku that enables high-density aquaculture and a culture net.

  As a means for achieving the above-mentioned object, in the method for cultivating a burdock, the burdock is arranged in the sea in a state where the net surface of the culturing net is expanded in the vertical direction, It was set as the method of making it grow.

  According to claim 2, in the method for cultivating foxtail owl, the rope is hung horizontally in the horizontal direction under the sea surface or below the sea surface, and the upper part of the aquaculture net is attached to the rope at a predetermined interval. A weight was attached to the lower part of the attached aquaculture net to hang down, and the aquaculture net was arranged continuously in the vertical direction along the rope.

  The aquatic network of claim 3 is the aquaculture net used in the aquaculture method of claim 1, the net surface on which the black mosk grows, the float attached above the net surface, and the net surface And the weight attached to the bottom of the aquaculture net is dropped into the sea, the weight sinks to the sea bottom and the lower end is fixed to the sea bottom, while the upper end of the net is lifted by buoyancy, The mesh surface was developed in the vertical direction.

By adopting the above configuration, the present invention has the following effects.
According to the method for cultivating a hornworm, the mesh surface of the aquaculture net is disposed in the sea in a state where the mesh surface is expanded in the vertical direction. Compared to a large aquaculture area.

  According to the second aspect of the present invention, since the aquatic nets are arranged along the stretched rope, the installation location is clarified by the ropes, and the aquatic nets can be arranged in an orderly manner at a predetermined interval.

In the aquaculture net according to claim 3, since it floats above the net surface and is provided with a weight below, the weight can sink just by dropping from the ship, the float can lift the net, and the net can be expanded up and down in the sea. it can.
In particular, due to the nature of ftmozuku that grows in the relatively rough reefs and boulders, diving work has been necessary at the time of installation and harvesting, and the installation work was extremely difficult. This greatly facilitates installation, management, and harvesting operations.

  Hereinafter, the best mode for realizing the present invention will be described with reference to the drawings.

The aquaculture net of the present invention will be described.
As shown in FIG. 1 (a), the aquaculture net of the present invention is attached to a net surface 1 on which a hornworm is grown, a bar 2 inserted on the upper end of the net surface 1, and a lower end of the net surface 1. The rod 3 is composed of a floating bar 4 disposed at both ends of the upper bar 2, and weights 5 attached to both ends of the lower bar 3.
The mesh is made of resin fibers such as polyvinyl alcohol fiber, nylon fiber, polyester fiber, cotton, hemp, palm or mixed fiber thereof, and a strand having a diameter of several millimeters is several cm to several tens cm. It is formed in the eyes.
The width of the mesh surface 1 is appropriately set depending on the installation location, but as an example, the width is set to 1.8 m × 2 m.

The bars 2 and 3 are installed in the horizontal direction in the sea while holding the upper and lower ends of the net.
Floats 4 are arranged on the left and right sides of the bar 2, and the upper and lower bar 2, 3 and the net 1 are lifted in the sea by the buoyancy of the float 4.
Weights 5 are respectively attached to the left and right sides of the bar 3, and the weights 5 bind sand bags and tie the ends of the strings 6 to both ends of the bar 3.
By using a sand bag as the weight 5, even if there is unevenness on the seabed, it can land flexibly and securely fix the main body.
The float 4 has a buoyancy that lifts the net surface 1 upward, but the weight 5 fixes the main body to the seabed against the buoyancy.

Next, a method for installing an aquaculture net will be described.
A pre-cultured zoomoss zoospore or filamentous body is attached to the mesh surface 1 of a predetermined area.
Bars 2 and 3 are attached to the upper and lower sides of the net 1, floats 4 are attached to the left and right of the upper bar 2, and weights 5 are attached to the left and right of the lower bar 3 to be loaded on the ship. In handling the aquaculture net, the upper and lower bar members 2 and 3 are overlapped, and the net is wrapped around the outer periphery of the central portion of the overlapped portion to make it compact (see FIG. 1B). Since floats and weights are attached to both ends of the bars 2 and 3, respectively, the central portion can be surrounded.
However, the attachment work of the float 4 and the weight 5 may be performed on the ship when dropping into the sea.
When the boat reaches the fishing ground, the aquaculture net is dropped into the sea while preventing entanglement between the bars 2 and 3 and the net surface 1 (see FIG. 1C).
This drop causes the aquaculture net to sink to the seabed with the weight lowered and the float up.
After sinking to the bottom of the sea, the body is fixed so that it does not move due to the gravity of the weight. On the other hand, the rod material is lifted by floating, and the aquaculture net is installed with the net surface developed vertically (FIG. 1). (See (d)).
Even if the waves in the aquaculture ground are rough, the aquaculture nets are floating in the sea, so they move flexibly with the waves, preventing damage to the alga bodies and aquaculture nets of the foxtail.
When the aquaculture net is installed for a predetermined period, the algal bodies of the mottled moss attached to the aquaculture net grow in the sea, and after the growth, the aquaculture net is pulled up together with the weight from the ship.
Since the aquaculture net is installed on the seabed of 1.5 to 5m, when harvesting, a long cutter and sickle are inserted from the ship, the bag is cut and the sand is drained and removed. It is good also as a method of raising after making it surface.

Next, a method for cultivating a hornbill according to the second embodiment is described.
As shown in FIG. 2, the method for cultivating the hornbill in the second embodiment is one in which a rope 7 is stretched under the sea surface and a culture net is attached along the rope 7.
