Description

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

As a measure to recover algae grounds that have been lost due to firewood burning more efficiently, or to create a good fishing ground by creating a new algae field in a place where there were no seaweeds previously, mainly algae growth 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 is initially cultured from the spores or cultivated from the young buds in a growth zone suitable for growth using 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, because algae are remarkably different in size and ecology at each growth stage, the environment required for algae gradually changes as it grows. Therefore, as described above, it has been difficult to grow algae from the spore and bud stage to the adult stage that forms the alga bed on the same growth member. Moreover, if the environment according to the various growth stages of algae is not prepared, for example, the algae grown on the growth member may not be satisfactorily settled and may be washed away by the ocean current. And the date is wasted.

  Therefore, the growth member of the present invention is an algae growth member having a growth member body for growing algae, and has a height of at least three stages on the surface of the growth member body in accordance with the growth stage of the algae. A plurality of different protrusions are provided.

  By adopting such a configuration, it becomes possible to arrange the growth environment according to the growth stage of the algae on the surface of the growth member main body with a simple configuration, and by using the growth member, the algae is good The probability of properly growing in the algae pond is dramatically improved.

  Furthermore, considering the simplicity of manufacturing and the degree of freedom in selecting the manufacturing method, it is desirable to provide the protrusions perpendicularly to the surface of the growth member main body or to form the protrusions in a cylindrical shape.

  In addition, the growth member main body can be more easily manufactured by molding the growth member main body with resin, and the convenience of handling is improved because it is possible to reduce the weight. For example, the hanging type intermediate growth system It can utilize suitably also.

  In addition, by injection molding the growth member main body, it is possible to obtain a member that is excellent in mass productivity and has little variation in quality.

  Furthermore, it comprises a spacer member having a living part where the roots of the algae expanded from the growing member body are settled, the growing member body is attached to the spacer member, and the growing member body and the growing member body are held on the seabed It is conceivable that the spacer member is interposed between the pedestal and the base.

  As a result, the grown algae can establish a solid and large root, and a growth environment suitable for the grown algae can be prepared in the engraftment part to further improve the algae growth environment.

  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 body to the spacer member in a detachable manner, for example, after algae roots expanded from the growth member body have settled on the survival part, a new growth member body is again attached to the spacer. It is possible to realize an algae pond where abundant algae are stored by attaching algae to the members. 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 order to facilitate the attachment / detachment of the growth member body, it is desirable to provide a recess for forming a gap between the spacer member and the growth member body in the spacer member or the growth member body.

  In addition, the seed algae are attached to the protrusions by hanging the seed yarns with alga spores attached thereto, so that the algae grow and grow on the growth member body. Since the roots can be stretched so as to hold the protrusions formed on the main body, algae can be stably established on the growth member main body.

  Furthermore, in order to easily fix the seed yarn hung around the protrusion to the growth member, an insertion port into which the seed yarn is inserted, a fixing port narrower than the insertion port, and the insertion port It is desirable to form a notch for fixing having a communicating groove that communicates with the fixing port in the growing member body, and insert and fix the seed yarn in order from the insertion port toward the fixing port.

  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, it becomes possible to arrange the growth environment according to the growth stage of the algae with a simple configuration on the surface of the growth member main body, and the algae grows well by using the growth member, which is appropriate in the algae ground. The probability of being settled in will dramatically improve.
