Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an aquaculture tool for forming a cage for abalone in the sea.

[0002]

[Prior Art]

 A conventional abalone farm for abalone culture is formed by suspending a cross-shaped frame on the sea surface and suspending aquaculture cages 21 and 31 as shown in FIGS. The aquaculture cage 21 shown in Fig. 5 is a bag net in which partition plates 7 made of synthetic resin arranged in multiple stages are connected by a rod 8 to form a shelter 9, and a feeding port 22 that is opened and closed by a fastener is provided on the side surface. 14 stores the shelter 9 described above.

Further, the aquaculture cage 31 shown in FIG. 6 has a corrugated partition plate 7 which is erected at regular intervals in a box 33 made of synthetic resin having a through hole 32 on the entire surface. In the center of 34, a hinged feeding window 35 is provided.

The aquaculture work is carried out by suspending the aquaculture cages 21 and 31 containing the abalone juvenile 18 with the cords 23 and 36 in the squares of the frame body. At the time of feeding, the aquaculture cages 21 and 31 are pulled up to the surface of the sea by a chain block or the like, the feeding port 22 or the feeding window 35 is opened, and seaweed such as seaweed is fed. Since the aquaculture cage 21 of FIG. 5 is one in which the partition plates 7 are provided in multiple stages in the vertical direction, it has a feature that a large number of juveniles 18 can be aquacultured with a small cage as compared with the cage 31 of FIG.

[0005]

[Problems to be solved by the device]

 However, the aquaculture cage 21 as shown in FIG. 5 is inconvenient because the aquaculture cage 21 must be lifted every feeding operation. Furthermore, the conventional abalone aquaculture equipment has a problem that foreign enemies such as fish can easily approach the aquaculture cage, and the abalone juvenile 18 is damaged and killed.

The present invention aims to provide an abalone aquaculture tool capable of cultivating a large number of juveniles with a small pan, preventing the invasion of external enemies, having a high yield of abalone, and being easy to feed. Has a purpose.

[0007]

[Means for Solving the Problems]

 The abalone aquaculture tool of the present invention comprises a frame 1 in the shape of a girder floating above the sea surface and a culture basket 6 for storing abalone, and the culture basket 6 is suspended on each square of the frame 1. There is. The aquaculture cage 6 is provided with a shelter 9 in which partition plates 7 made of synthetic resin arranged in multiple stages are connected by a rod 8 or the like at upper and lower intervals, and the shelters are housed in a bag net 14. Through holes 10 are provided in each of the partition plates 7 of the shelter 9, and at least one of the through holes 10 of each of the partition plates 7 is arranged so that they are vertically aligned with each other. Further, the frame body 1 is provided with a bottomed protective net 3 that covers the entire aquaculture cage 6 suspended from the frame body 1.

[0008]

[Action]

 When the aquaculture tool of the present invention is installed in the sea, the entire aquaculture cage 6 for storing abalone is covered with the protective net 3, and each aquaculture cage 6 is covered with the bag net 14 to be doubly protected. Therefore, external enemies such as fish cannot penetrate into the cage, and there is no risk that the abalone juvenile 18 will be caught and scratched between the meshes of the bag net 14. Further, at the time of feeding, the pipe 16 is inserted into the through hole 10 of the shelter 9 suspended by the frame body 1, and the pipe 16 is moved up and down so that its lower end faces each step. Insert seaweeds such as seaweed and feed each stage. This eliminates the need to raise each cage to the surface of the sea and simplifies feeding operations.

【Example】

 FIG. 1 is an overall perspective view of the aquaculture device of the present invention. The aquaculture equipment has a frame body 1 in which steel materials 19 are assembled in a cross beam shape. The frame body 1 is floated on the sea surface by eight floats 2 fixed to the four corners and is not shown. It is moored to the seabed with an anchor rope. Protective nets 3 with a bottom are bound to the four sides of the frame 1, and the protective nets are installed in the sea in an expanded state by weights 4 provided at the four corners of the frame. It forms a pot for you.

The illustrated frame 1 is provided with nine squares 5, and aquaculture cages 6 shown in FIGS. 2 and 3 are suspended in each square 5. The aquaculture basket 6 has a structure in which a plurality of partition plates 7 made of vinyl chloride are connected in multiple stages by rods 8 at regular intervals to form a shelter 9, and the shelter is surrounded by a bag net to be described later. There is. The shelter partition plate 7 is provided with a total of five through holes 10 at its sides and central portion, and each of the through holes 10 formed in the partition plate 7 at each stage has a straight line extending in the vertical direction. It is located on the line. The abalone juveniles 18 placed in each stage are attached to the upper and lower surfaces of the partition plate 7, and move to different stages through the through holes 10.

A horizontal U-shaped handle 11 is provided on the uppermost partition plate 7. By connecting a rope 12 bound to the handle 11 to the frame body 1, each shelter 9 is attached to the frame body 1. Suspended at 5th level. The shelter 9 is surrounded by a square bag-like net 14 having an open upper surface, and a gap is provided between the side of the partition plate 7 and the net 14. The bag net 14 is suspended from the shelter 9 separately from the shelter 9 by the string 15, and when it becomes necessary to replace the bag net 14 with dirt such as barnacles or water scales during the aquaculture period. First, the shelter 9 is pulled up to the surface of the sea, the bag net is replaced with a new one in that state, and then the shelter 9 is lowered and stored in a new bag net 14.

FIG. 4 is a perspective view showing a feeding operation. The pipe 16 is inserted into the through hole 10 of the partition plate 7, and the pipe 16 is moved up and down so that the tip opening faces each step of the shelter 9. In this state, seaweed 17 such as seaweed is pushed from the upper end of the pipe 16 to feed. .. As a result, the bait 17 can be evenly inserted into each stage of the shelter 9 and the shelter 9 does not have to be pulled up one by one during feeding, so that the work load during feeding is greatly reduced. It is also possible to cultivate more abalone with smaller shelters by increasing the number of shelters.

[0013]

[Effect of the device]

 Since the aquaculture device of the present invention double-protects the abalone with the protective net and the bag net, the abalone is not damaged by external enemies and the yield is increased. In addition, it is not necessary to pull up the aquaculture cages one by one when feeding, which significantly reduces the work load during feeding. Moreover, since it is not necessary to consider the lifting work, the number of shelters can be increased to increase the number of aquacultures per aquaculture area.
