Description

  The present invention relates to a growth member for growing algae forming an algae field.

In order to recover the seaweed beds that have been lost due to firewood burning more efficiently, or to create a good fishing ground by creating new seaweed beds in places where there were no seaweed beds, A so-called removable algae breeding reef has been considered in which the growth member and the pedestal member are detachably attached in consideration of the function and the pedestal function for fixing to the seabed. In this detachable algae breeding reef, the algae should be constructed if the algae are initially cultured from the spores or cultivated from the young buds in the growth zone suitable for growth using the growth members, and the algae grows to some extent. The growth member is transferred to the zone and attached to the pedestal member to form a seaweed breeding reef. (See Patent Document 1)
Japanese Patent No. 3532865

  However, in order to initially culture algae from spores or to perform intermediate culture from young buds using growth members, it is necessary to first attach very small spores and the like to the growth members. For this reason, a method is considered in which seed yarns to which the algae spores and the like are attached are attached to the surface of the growth member and the spores are attached to the growth member, but the growth member is installed in the sea or the like. Therefore, in order to employ the attachment method using the seed yarn, the seed yarn must be firmly fixed to the growing member so that the seed yarn is not washed away by the ocean current.

Therefore, the growth member of the present invention includes a growth member main body for growing algae, and a spacer member having an attachment portion attached to the growth member main body and energized by algae roots expanded from the growth member main body. In the algae growth member that attaches the seed yarn having the algae spores attached to the surface of the growth member main body, the insertion port for inserting the seed yarn, and a width wider than the insertion port A notch for fixing having a narrow fixing port and a communication groove that communicates the insertion port and the fixing port is formed in the growth member body, and the seeds are sequentially arranged from the insertion port toward the fixing port. It is characterized by inserting and fixing a thread.

  By adopting such a configuration, it is possible to guide the seed yarn to the narrow fixing port through the communication groove while providing a wide insertion port so that the seed yarn insertion start operation can be performed smoothly. Therefore, it is possible to realize a growing member that can easily and firmly fix the seed yarn attached on the surface of the growing member main body with a structure that can be easily manufactured.

  Furthermore, by providing at least a pair of the fixing notches on the same side of the growing member main body, for example, one end of one seed yarn is fixed to one fixing notch and the other end is fixed to the other. By fixing to the notch for use, even if one end of the seed yarn is pulled in the direction of releasing the fixing, it is fixed at the other end, so that a stable fixed state can be maintained.

  In addition, by making the opening width of the insertion port approximately the same as the width of the seed yarn, and making the opening width of the fixing port approximately half or less of the width of the seed yarn, The robustness of the growth member main body can be maintained by suppressing the notch of the growth member main body to the minimum necessary while exhibiting the effect of easily and firmly fixing the growth member to the growth member.

  Further, it is desirable that the opening width of the insertion port is gradually narrowed toward the fixed port so that the insertion operation into the fixed port can be performed more smoothly.

  In addition, the growth member body can be easily manufactured by molding the growth member body with resin, and the convenience of handling is improved because it is possible to reduce the weight, for example, a hanging type intermediate growth system, etc. Moreover, it can utilize suitably.

Furthermore, the present invention comprises a spacer member having an engraftment part in which algae roots expanded from the growth member main body are activated, and the spacer member includes the growth member main body and a pedestal for holding the growth member main body on the seabed. Provided with a recess in the spacer member or the growth member main body to form a gap between the spacer member and the growth member main body into which the seed yarn fixed in the fixing port enters. It is characterized by being .

  Thus, for example, by storing the end portion of the seed yarn fixed to the fixing port in the recess, a suitable attachment state can be realized without hindering the attachment of the spacer member by the seed yarn.

  In addition, by providing the spacer member, the grown algae can have a solid and large root, and the living environment suitable for the grown algae is prepared in the budding area, so that the algae growing environment is further improved. Can do.

  Furthermore, since the growth member main body is separated from the pedestal by the spacer member, for example, it is possible to prevent the seabed sand from flowing and algae spores on the growth member main body from being buried in the sand. It is also possible to secure a site where the roots of the grown algae are stretched.

  In addition, by attaching the growth member main body to the spacer member in a detachable manner, for example, a growth in which a new seed yarn is attached after roots of algae expanded from the growth member main body have settled on the survival part. By attaching the member main body to the spacer member again and adding more algae, it is possible to realize an algae reservoir storing abundant algae. In addition, when algae does not grow on the initially attached growth member body, it is possible to flexibly respond to individual growth conditions, such as replacing the growth member body with a good growth. .

  Furthermore, by making the spacer member separate from the growth member body to which algae spores and the like are attached, the degree of freedom of the shape and weight of the growth member body is dramatically increased. Can be made lightweight and easy to handle.

  In addition, the seed yarn is attached to the surface of the growth member main body by attaching the seed yarn by hanging the seed yarn having algal spores attached to the protrusions formed on the surface of the growth member main body. It is possible to attach evenly.

  In addition, by providing an attachment part for attaching a hanging tool for suspending the growth member main body in water to the growth member main body, for example, only the growth member main body is suspended in the sea, and algae is initially cultured from spores. It is possible to easily realize a method for growing algae to a certain extent and to further improve the growth of algae.

  As described above, the seed yarn can be guided to the narrow fixing port through the communication groove while providing a wide insertion port so that the seed yarn insertion start operation can be performed smoothly. Therefore, it is possible to realize a growing member that can easily and firmly fix the seed yarn attached on the surface of the growing member main body with a structure that can be easily manufactured.
