Abstract

(57) [Summary] [Purpose] In aquaculture of implantation organisms, it is possible to effectively prevent a decrease in the survival rate of the cultured implantation organisms due to human error, and to provide a shelter for the cultivation of implantation organisms that enables efficient aquaculture. The purpose is to provide. [Structure] A FRP plate 1A having a concave curved surface is provided with a large number of through holes 1B of a size through which the implantation organisms can pass through, and the holes are submerged in the aquaculture pond to form a protective shelter. .

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a shelter for aquaculture of implantation organisms, and more particularly to a shelter suitable for aquaculture of implantation organisms such as abalone, turban shell and sea urchin.

[0002]

[Prior art]

 Conventionally, when abalone, turban shell, sea urchin, etc. are cultivated in a pond, the algae used as food for hanging a plastic corrugated sheet in the pond during the period from the floating life to the implantation life of the larvae hatched from fertilized eggs. The seedlings are generated and attached, and the young and young of implantation organisms such as juveniles are implanted and grown on this.

[0003]

[Problems of conventional technology]

 By the way, when regularly cleaning the pond in the cultivation of the above-mentioned implantation organisms, when pulling up the above-mentioned plastic corrugated sheet, crushing the juveniles adhering to the plastic corrugated sheet due to mishandling, or When a child grows and expands its activity range and becomes dispersed in the bottom of the pond, when the unnecessary plastic corrugated sheet is pulled up, the above plastic corrugated sheet is removed and killed by the impact. Occasionally, human error could reduce the survival rate of aquaculture organisms.

[0004]

[Problems to be solved by the device]

 In view of the above problems, the present invention has been made with the object of providing a shelter for cultivation of implantation organisms, which can effectively prevent a decrease in the survival rate of the culture implantation organisms due to human error and can efficiently perform cultivation. It is a thing.

[0005]

[Means for Solving the Problems]

 That is, the shelter 1 for culturing implantation organisms of the present invention has a FRP plate 1A having a concave curved surface and a large number of through holes 1B having a size through which the implantation organisms pass through, which are uniformly distributed. It is characterized by that.

[0006]

【Example】

 Next, an embodiment of this invention will be described. 1 is a perspective view of an embodiment of the present invention, FIG. 2 is a plan view of the embodiment, FIG. 3 is a side view of the embodiment, and FIG. 4 is a side view of another embodiment.

A shelter 1 for culturing implantation organisms of the present invention comprises a FRP plate 1 A having a concave curved surface, and a large number of through holes 1 B sized to allow the baby to pass through, which are uniformly dispersed. Has been. In the above embodiment, the FRP plate 1A having the concave curved surface may be a box-shaped FRP plate that is curved with a constant curvature as shown in the figure.

[0008] The size of the hole 1B formed in the FRP plate is determined by the size of the fry of the living organism such as the shell diameter of the young shellfish. Depending on the size of the shell, it will be around 15 mm or more or 20 mm or more depending on the size of the shell. Regarding the dispersed state of the holes 1B, the larger the hole diameter, the smaller the number of holes. The FRP plate can also be formed by using a defective product that is generated during manufacturing of the FRP pipe.

[0009]

[Action]

 The planting aquaculture shelter 1 of the present invention, when suspending a corrugated plastic plate that generates algae, which feed the young of the planting organisms, in the pond, simultaneously forms a curved surface and a bottom surface on the pond bottom. It is sunk in a posture with a space in between. The juveniles in the growing process enter the protective space inside the aquaculture shelter 1 through the hole 1B as the activity range expands, so that they are effectively protected from the impact of falling plastic corrugated sheets. Also, if the plastic corrugated sheet and the aquaculture shelter 1 are installed in contact with each other, even young fry that have a small activity range can enter and exit the shelter 1 and enter the shelter 1. Because it is protected, the survival rate is increased accordingly.

[0010]

[Effect of device]

 Since this invention is configured as described above, it is possible to effectively protect extremely weak baby larvae, and it is effective in killing baby larvae due to an accident when cleaning aquaculture ponds or pulling up unnecessary plastic corrugated plates. Therefore, it is possible to effectively prevent the decrease in survival rate due to human error. In addition, since the shelter 1 for cultivation of implantation organisms of the present invention is made of FRP, it is not corroded by seawater and is strong in strength. Furthermore, it is possible to use defective products produced during FRP pipe production. Since it can be manufactured, it has various practical effects such as the utilization of waste.
