Description

TECHNICAL FIELD The present invention relates to a seafood breeding reef, and more particularly to a seafood breeding reef suitable as a juvenile shellfish breeding reef for abalone, abbot, and the like.

(Prior Art) Conventionally, as a seafood breeding reef, a cubic frame is formed by three or four columns and a beam connecting the columns at an upper portion and a lower portion, and a screen material is stretched on each surface of the cubic frame. It is known that a box frame formed by filling a large number of stone materials.

When these are used as a reef for releasing juvenile molluscs such as abalone and abbot, feeding damage caused by fish of juvenile molluscs released on the reef is a serious problem in terms of proliferation. Recently, in order to protect juvenile shellfish immediately after release, which often suffers from feeding damage, as a juvenile shell insertion protection device for abalone, etc. A pipe having an inverted T-shaped pipe has been proposed. (Actual development 61-
(Patent No. 188467) (Problems to be solved by the invention) The abalone juvenile-feeding protection device described above is manufactured separately from the box frame, and is attached to a beam or the like on the top surface of the box frame to form an inverted T-shaped lower pipe. Since it has to float from the bottom of the box frame, the assembly is troublesome and the reverse T
The V-shaped pipe is unstable.

Further, since the inverted T-shaped pipe is arranged in the center of the box frame, the pipe interferes with the filling of the stone material into the box frame.

Furthermore, the abalone juvenile shell protection device consisting of an inverted T-shaped pipe causes clogging and prevents juveniles from coming out of the exit unless the inside of the pipe is cleaned after a certain period of use.
If necessary, it must be cleaned in the sea, but since the outlets on both sides of the lower end of this pipe cannot be cleaned, the outlets are often blocked and unusable.

The present invention, it is not necessary to separately provide an input protection device for the release of juvenile shellfish such as abalone, abalone, and the like, and there is no problem in filling the stone material into the box frame, and abalone,
The purpose of the present invention is to provide a seafood breeding reef that allows easy cleaning of the larvae and other shellfish discharge areas and is reusable.

(Means for Solving the Problems) In order to achieve the above object, in the seafood breeding reef of the present invention, a cubic frame is formed by three or more pillars and a beam connecting each pillar at the upper and lower parts. In a seafood breeding reef filled with a large number of stone materials in a box frame formed by stretching a screen material or a plate material on each surface except at least the upper surface of the cubic frame, the pillars of the box frame are formed by hollow pipes, A large number of small holes are provided on the surface of the hollow pipe that faces the inside of the box frame, an opening is provided at the upper end of the hollow pipe, and a removable lid that closes the opening is provided.

To each pillar of the hollow pipe, it is effective to attach a blind plate toward the adjacent pillars so that the large number of small holes provided in each pillar of the hollow pipe are located on the inner surface side of the blind plate. is there.

Furthermore, a cubic frame is formed by three or more columns and a beam connecting each column at the upper and lower parts thereof, and at least one hollow pipe is formed as an inner column that forms a part of the structure therein.
The main pipes are arranged, and the upper and lower parts of the hollow pipe are connected by an inner beam to the upper and lower parts of each column, or between the upper and lower beams connecting the columns, and at least the upper surface of the cubic frame is connected. Exclude screen material or plate material on each surface to form a box frame,
A large number of small holes are provided on the outer peripheral surface of the hollow pipe, an opening is provided at the upper end, a large number of stone materials are filled in the box frame, and a removable lid is provided to close the opening at the upper end of the hollow pipe. It is a thing.

Further, each column other than the middle column is also a hollow pipe, and a large number of small holes are provided on the surface of the hollow pipe facing the inside of the box frame and an opening is provided at the upper end, and the upper end of the hollow pipe is provided on the upper surface of the box frame. It is provided with a detachable lid that also closes the opening.

(Operation) The seafood breeding reef constructed as described above is provided with a small hole in the surface facing inward of the box frame in the pillar or middle pillar of the hollow pipe forming part of the structure of the cubic frame. Since an opening is provided on the upper or upper surface to form a juvenile shell discharge tube for abalone, abbot, etc., an abalone juvenile shell protection device is manufactured separately from the box frame and used for the box frame. Since it is not necessary to attach it, the box frame can be easily assembled and manufactured. In addition, since there is no obstruction of the inverted T-shaped pipe inside the box frame unlike the conventional abalone juvenile feeding protection device, the stone material can be filled smoothly without any trouble.

Then, the juvenile shellfish such as Abalone beetle for the seafood reef of each invention deposited on the seabed is released from the upper end opening of the pillar or the middle pillar of the hollow pipe which is the juvenile shell discharge tube. Immediately put in, and after putting in, close the opening with a removable lid. As a result, feeding damage caused by seafood is prevented, and juveniles such as abalone and abbot crawl out from the small holes on the surface facing the inside of the box frame, infiltrate between the stone materials filled inside the box frame, and eventually become stone materials naturally. Implant.

However, the columns of the hollow pipe, which is the juvenile shell, and the inside of the pillar, and the small holes, which are the juvenile craw-out holes, will be blocked by seaweed, shells, etc. even after a year, but the lid of the opening at the top will be removed. It can be cleaned easily by removing it, so after the cleaning is finished, young shellfish such as abalone and Trokobushi can be put in again, and the seafood reef can be used for a long time as a young shell reef breeding reef.

As described above, the seafood breeding reef of each of the first to fourth inventions is a box of hollow pipe pillars 1 and middle pillars 14 forming a part of the structure of the respective cubic frames 3 and 3 '. Slit holes 8 and 8'facing the inside of the frames 5 and 5'are provided. Pillar 1, middle pillar 14
Since the openings 9 and 9'are provided at the upper end of the box to form a juvenile shell discharge tube for abalone, Tokobushi, etc., an abalone juvenile shell protection device is manufactured separately from the box frame as in the conventional case. Since it is not necessary to attach it to the frame, the box frame can be easily assembled and manufactured. Further, in each of the embodiments, inside the box frames 5 and 5 ′,
Since there is no obstacle of the inverted cross-shaped pipe like the conventional abalone juvenile feeding protection device, the filling of the stone 6 can be smoothly performed without any trouble.

Then, a hanging rope is hung on the hanging ring 12, and the larvae of the abalone, abbot, and the like for the seafood breeding reef of each example, which is hung down and sunk by a crane of a crane ship, is sunk to form a juvenile shell. From the openings 9 and 9'on the upper ends of the hollow pipe pillar 1 and the middle pillar 14, the fry shells attached to the kelp are quickly put in, and immediately after the putting in, the respective openings 9 and 9'are attached and detached. Closing with possible lids 10, 10 '. As a result, feeding damage due to fish is prevented, and juveniles such as abalone and abbot are crawled out from the slit holes 8 and 8'on the surface facing the inside of the box frames 5 and 5'and inside the box frames 5 and 5 '. It infiltrates between the stone materials 6 filled in, and eventually the stone materials 6 are naturally landed.
And the pillar 1 and the middle pillar 14 of the hollow pipe which is a juvenile shell
The slit holes 8 and 8 ′, which are the crawl-out holes of the juvenile shell, are blocked by seaweed, shells, etc. after a year, but the lids 10 of the openings 9 and 9 ′ at the upper ends of the pillar 1 and the middle pillar 14 are closed. 10 '
If you remove it, it is easy to clean the pillars 1 and the middle pillars 14 without any bends, so you can add juveniles such as abalone and abbot after the cleaning, and the seafood reef is released into juveniles. It can be used as a reef for many years.

Further, if the lid 10 is a translucent lid or a net-like lid, it is most suitable for growing juvenile shellfish such as abalone and abbot that move to the dark side against the light.

In the seafood breeding reef of the second invention, the features of each of the embodiments are as follows: a blind plate 13 is provided from both side surfaces of the pillar 1 of the hollow square pipe at the four corners to the first screen material 4, and a large number of blind blind plates 13 are provided. Since the slit hole 8 is located on the inner surface side, it is possible to prevent the juvenile crawling out from the slit hole 8 from directly moving to the outside of the seafood breeding reef.

In the seafood breeding reef of the third invention, since the juvenile shell discharge tube is the center pillar 14 of the hollow square pipe, the juvenile shell crawling out from the large number of slit holes 8'of the middle pillar 14 proliferates the seafood. It does not infiltrate between the stone materials 6 inside the reef and does not move to the outside, and can sufficiently protect the juveniles immediately after release. In addition, since the middle pillar 14 is a thick hollow square pipe, the pillars 1 at the four corners, the side pillars 1 ', the beams 2, etc. can be thinned to reduce the weight of the cubic frame 3'.

In the seafood breeding reef of the fourth invention, not only the center pillar 14 but also the pillars 1 at the four corners are juvenile shell discharge tubes, so a large juvenile shellfish for releasing and growing a large amount of juvenile shellfish. It is most suitable as a release reef.

In each of the first to fourth inventions, the thickness of the pillar 1 and the center pillar 14 of the hollow square pipe, which is a juvenile shell discharge tube, and the dimensions of the slit holes 8 and 8'are the kind and number of the juvenile shell shells. The size is appropriately selected according to the size and the like. Further, the box frames 5 and 5'of the seafood breeding reefs of the respective examples are all planar squares, but the present invention is not limited to this, and may be planar triangles, pentagons or hexagons. Accordingly, the third invention and the fourth invention
The upper and lower parts of the middle pillar 14 of the seafood-breeding reef of the invention are connected not only in the middle of the upper and lower beams 2 on each side but also by the inner beam 15 to the upper and lower parts of the pillar 1 at each corner. Is also good.

Furthermore, the seafood reef of each of the above-mentioned examples is for sinking on a relatively stable seabed, but when sinking on an unstable seabed such as a sandy land, legs are attached to the lower end of the pillar 1. It is good to extend it.

In addition, the seafood breeding reefs of each of the above-mentioned examples are circular holes, square holes, although the juvenile shell crawling holes of the hollow square pipe 1 and the middle pillar 14 are slit holes 8 and 8 ′. Other small holes may be used. Considering the shape of juvenile shells such as abalone, it is best to make the slit hole long in the horizontal direction. The pillars 1 and the middle pillars 14 are not limited to the medium-angle hollow pipes, but may be round pipes. Particularly, when the plane shape of the box frame 5'of the seafood breeding reef of the third invention and the fourth invention is triangular, pentagonal, hexagonal, etc., the middle pillar 14, which is a fry shell, is a triangular pipe, a pentagonal pipe hexagon. It is recommended to use a pipe and to provide juvenile crawling holes of appropriate shape on each side.

Further, although the lower ends of the pillars 1 and the middle pillars 14 which are the juvenile shell discharge tubes are closed with a plate, they may be closed with a porous plate or a net. Further, gravel or the like may be appropriately inserted into the pillar 1 and the center pillar 14 according to the number and size of the released juveniles to adjust the height at which the juveniles are submerged between the stone materials 6. .

Although the screen material or the plate material is not attached to the upper surfaces of the box frames 5 and 5'in each of the above-mentioned embodiments, the screen material or the plate material may be attached depending on the situation of the seabed.

(Effects of the Invention) The seafood breeding reef of the first to fourth inventions is a hollow pipe pillar or middle pillar forming a part of the structure of a cubic frame, and a small hole in the surface facing the inside of the box frame. Is installed, an opening is provided at the upper end, and a juvenile shell discharge tube for abalone, abbot, etc. is formed, so it is not necessary to install a juvenile shell protective device inside the box frame separately from the box frame. Manufacturing is simple, and filling of stone material into the box frame can be done smoothly. The release of juvenile shellfish such as abalone and abbot to the seafood reef sunk on the bottom of the sea is thrown in through the upper opening of the hollow pipe pillar or middle pillar that is the juvenile shell discharge tube, and the opening can be detached after the introduction. By covering it with a naive lid, feeding damage by fish etc. is prevented, the juvenile crawling out from the small hole on the surface facing the inside of the box frame and infiltrating between the stone materials filled inside the box frame, and eventually it will naturally attach to the stone material. Since it floors, it is extremely useful as a reef for releasing juveniles. Also, the hollow pipe pillars and middle pillars, which are fry shells, can be easily cleaned by removing the lid that closes the opening. The reef can be used for a long time as a fry releasing reef.

Further, in the second invention, since the blindfold plate is provided and the large number of small holes are located on the inner surface side, it is possible to prevent the juvenile crawling from the small holes from directly moving to the outside of the seafood reef. .

Further, in the third invention, since the middle pillar is used for the juvenile shell discharge tube, juveniles crawling out from the small holes can easily enter between the stone materials.

In the fourth invention, it is most suitable as a large reef for growing juveniles.
