Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a culture device for creating an 8I field, and more specifically, a culture device for creating an N field that improves the adhesion of spores such as algae floating in seawater or fresh water. Regarding the culture medium 11 device.

This cultivation device for creating a seaweed bed is used to create a seaweed bed, and it can also be used to create an underwater forest by setting it up in the sea.

[Prior Art] Many of the coasts of Japan are not ideal environments for fishing, as the formation of algae spores is hindered by the phenomenon of rocky shores, and there is insufficient growth of algae such as algae and seaweed.

In other words, if phytoplankton occurs in sea areas, zooplankton will be cultured and produced, but if algae do not occur, the amount of dissolved oxygen in the seawater will be low, and food for fish and shellfish will be depleted. Become.

In view of the above points, there is currently an urgent need to create seaweed beds in Japan's coastal waters, in violation of the US Coastal Fisheries Act.

Conventional 5J11 development has involved adding natural stones, concrete blocks of various shapes, and destroying rocks that have caused rock formations to expose new rock surfaces. In these cases, the amount of adhesion of algae spores, etc. is not necessarily large, and it is not possible to create a sufficient seaweed bed.

Also, kelp and other plants are usually inoculated into ropes. In this method, a certain rope is twisted back by force, then inoculated, and then tightened again, but this can damage the spores and crush the buds, and the work is laborious. Furthermore, it cannot be said that algae spores easily and sufficiently attach to this rope.

The present invention overcomes the above-mentioned problems, and is a culture medium for creating seaweed beds that improves the adhesion of spores of floating algae in the natural world, and is suitable for creating seaweed beds and further suitable for underwater forests! The purpose is to provide one device.

[Means for Solving the Problems] The culture device for deep field creation of the present invention is characterized by comprising a culture body formed of a fiber aggregate and a holder that holds the culture body in water.

The fiber aggregate is an aggregate of various fibers. For example, felt is used as this fiber aggregate. The fibers used for this felt may be organic fibers or inorganic fibers, but organic fibers are attractive. This is because spores adhere better. Also, among organic fibers, it is more synthetic than natural fibers! For example, nylon, polyester, poly(7-crylonitrile), wholly aromatic polyamide, etc. are preferable. This is because synthetic fibers have excellent mechanical strength, seawater resistance, weather resistance, and the like. Although this culture body can be in the form of a sheet, it is preferably rod-shaped or cylindrical, particularly columnar or cylindrical. This is because the waves have less resistance. To make this columnar or cylindrical shape, you can usually roll up a sheet of felt into a roll,
It is also possible to fill felt chips into a predetermined mesh-like reinforcing portion.

As shown in FIG. 1, the above-mentioned culture body can have a cylindrical shape consisting of a core part 2 formed of a fiber aggregate and a mesh-like reinforcing part 3 covering the outer peripheral surface of the core part 2.

Moreover, this culture body can also have a cylindrical shape, as shown in FIG. 2, in which both the inner and outer circumferential surfaces of the core portion 2a are covered with mesh-like reinforcing portions 3b and 3a. Further, in the case of using felt scraps, for example, the reinforcing portions can also be used on the upper and lower surfaces of the core. Note that this reinforcing part is not limited to cases in which the shape of the core part is the above-mentioned columnar or cylindrical shape, but also in the case where the core part has a columnar or cylindrical shape having another shape, or even a plate-like or sheet-like shape. It can also be applied to chino. The size of the mesh constituting this reinforcing part may be as long as it can be inoculated, but it is preferably 2 to 201111R1, more preferably 10
~151M. Note that the size of the openings must be such that when internal felt tears are used, they do not leak to the outside. Further, the yarn constituting this net is usually 0.3 to 0.911 IIN, and preferably has a certain degree of rigidity and can hold the inner core. This culture body can be fixed to the holder through the caps provided above and below the core.

The above-mentioned culture body can have inside thereof a massive ceramic far-infrared emitter having the function of absorbing and emitting far-infrared rays. As this material, for example, "Biostone" (trade name, manufactured by Koha Marine Research Institute), which is obtained by mixing vegetable cellulose and steel slag, molding and firing, can be used. This far-infrared emitter can be made into various shapes and sizes depending on the purpose, the inner diameter of the inner cylinder, etc., but it is usually in the shape of a mazetsuk and has a size of about 32 x 32 x 25 (t) mill. used.

The above-mentioned holder is for holding the above-mentioned culture body in water.

As shown in FIG. 5, this holding body includes a weight 7, a float 8,
a string 9a that holds the culture between the weight 7 and the float 8;
9b. Alternatively, this may be a weight 7a fixed to the culture body as shown in FIG.

In the former, the culture body is suspended in the middle of the water, and in the latter, it is placed on the bottom of the water. In these cases, rather than tying the outer periphery of the culture body with lobes and fixing the lobes to a weight or the like, it is preferable to provide locks on the top and bottom of the culture body and fix them to the weight or the like with through bolts and nuts. The former is because the rope around the outer periphery of the culture body rubs against the outer periphery of the culture body and crushes the buds.

[Example] Hereinafter, the present invention will be specifically explained with reference to Examples.

FIG. 2 shows a plan view of the culture 11 device for creating a seaweed bed used in this example. The culture body 1 of this culture device for creating a seaweed bed has a cylindrical core part 2a formed by O-rolling felt and a net-like reinforcing part (outer cylinder) that covers the outer peripheral surface of the core part 2a.
A cylindrical body (length 5I11, outer diameter 20C11, inner diameter 10
CI) There is. Both the inner tube 3b and the outer tube 3a have a mesh size of 10 to 15111, and the outer diameter of the thread is 0.5.
~0.7IIm plain weave nylon-6,6
Consisting of

The felt used is a blend of synthetic Mi11 such as nylon-6,6 and polyester. As shown in FIG. 4, caps 4 are placed above and below this core portion 2.
was provided and tightened with a through bolt 5 at the lower cap (not shown) to construct the culture body 1.

As shown in FIG.
and the float 8 were connected by a string 9b, and the lower cap 4b and the weight 7 were connected and held by a string 9a, and then thrown into a predetermined sea.

Water-based bacteria colonize this cultivation device from the 5th to 7th day, and in the summer, from around the 10th, sea lettuce, green algae, and sponges such as the seaweed can grow, and in the winter, kelp and other floating algae in the area can grow. It begins to settle in about a day. Note that algae spores with a high added 1lIi value can also be inoculated in advance.

Water ring! The device has a cylindrical culture body made of felt. Therefore, the Honbo m device can exist stably in the sea with little wave resistance, and this felt is made of organic trade fibers.
．． As shown in the figure, since they are intertwined, the adhesion area is extremely large, and since phytoplankton and zooplankton prefer these organic materials, spores tend to adhere to them. FIG. 3 is a microscopic photograph (magnification: 50) of felt, where the white part shows the plot and the black part shows the space. Also, since this felt is made of synthetic polymer, it will not corrode in seawater. Furthermore, since the main culture device has a predetermined mesh-like reinforcing portion, it has appropriate rigidity, the felt portion is firmly held, and furthermore, it is easy to inoculate. Matamotobo l
! In the device, since the culture body is connected to the holder by the upper and lower caps, buds such as spores, growing kelp, etc. exposed through the mesh will not be damaged or removed.

[Effect of the invention] Culture for creating seaweed beds of the present invention! The apparatus is characterized in that it consists of a culture body formed of 11 m aggregates and a holder for holding the culture body in water. Therefore, since the water ring 11 device has a significantly large surface area for adhesion, when it is immersed in water such as seawater, the adhesion of spores such as algae floating in the natural world can be significantly improved. Therefore, by using the main culture device, it is possible to easily create a seaweed bed, and by establishing a large number of these cultures, it is also possible to facilitate the creation of an underwater forest. In addition, in the main culture device, seasonal I
11.The equipment cost and assembly alone are extremely cheap.
