Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to the Isebi reef, and more specifically, to the Isebi reef that allows the establishment of Puerlus, the setting of juvenile shrimps, and the habitat of adult shrimps within the same reef. Pertain.

Conventional technology Recently, the setting of 200 nautical mile economic zone has advanced internationally, the marine environment has become more severe than expected, and the necessity to secure seafood resources from the coast as much as possible has increased, and the importance of its aquaculture measures has become important. The current situation is being screamed.

Especially, lobster is a valuable resource and is said to be decreasing year by year, and how to secure and proliferate is a very important issue, but at present, there are many uncertain factors regarding its ecology, The means for solving the problem has not been established yet.

Generally, a method of actively installing artificial reefs in the sea is adopted to increase the catch of seafood. These artificial fish reefs are exclusively for collecting grown seafood and the like to form a fishing ground with high fishing efficiency, and are usually called fish reefs for collecting.

In addition to protecting fish and shellfish, a protected reef that artificially attaches and hatches eggs such as seafood and protects and fosters juvenile fish has been proposed and implemented.

This protected reef forms a habitat environment and a protected environment suitable for the protection and breeding of juvenile fish, etc. It is suitable for the settlement and habitation of diatoms and other feed organisms, and is intended for the continuous resting and resting of juvenile fish. It is equipped with conditions such as suitability.

However, the fish reef of the conventional example is not suitable for the protection and breeding of lobster even if it is for collecting and protecting, and if the fish reef of the conventional example is used as it is, the engraftment rate of the puerurus is low, and the puerleus has a certain degree. Even if they settle, other seafood, which are external enemies, prey on them because they are small when Puerlus prey on feed organisms. It moves from the fish reef.

That is, the fish reefs described in Japanese Utility Model Publication No. 48-61092 and Japanese Utility Model Publication No. 51-16095 are so-called rod-shaped fish reefs. It is provided so as to project from the above. With this rod-shaped fish reef, the larvae formed between the fibrous bodies protect the spawning and young fish from external enemies, and allow them to continue to live and rest. In addition, the fish reef described in Japanese Utility Model Publication No. 57-201163 is composed of a truncated cone-shaped or truncated pyramid-shaped concrete base and a flock plate attached to this surface.
Moreover, it is formed by flocking fibrous bodies on the surface of the flocked plate. Also in this fish reef, many shades suitable for growing juveniles are formed on the surface of the flock.

However, all of these fish reefs positively form the shade part by the fibrous body, but simply forming the shade part cannot increase the settlement rate of puerle and is suitable for ecology of puerle. If the density is not high, the settlement rate of Puerlus is low, and due to the presence of the shade, the natural enemies approach rather, and Puerlus is predated with the feed organisms.

DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention The present invention is intended to solve the above-mentioned drawbacks. Specifically, a flocked body having an appropriate density is provided in the frame body to form a shaded part by the flocked body, and the puerle is attached to the flocked body. While making it easier to grow,
The frame prevents the invasion of seafood, which is an external enemy, and further, a nursery ground consisting of spherical structures such as stones is provided below the frame.
We propose an Isebi nursery reef that can move and settle and live in a nursery consisting of a spherical structure even if Puerlus transforms into juvenile shrimp.

Means for Solving the Problem and Its Actions That is, the Isebi nursery reef according to the present invention is a seedling consisting of a box-shaped frame body having a hair transplant body attached to the inside of a base having a slit near the center. Nursery, which consists of a container and a spherical structure placed between each pillar of the pillars that support the seedling container provided at the four corners of the seedling container, and a window-opening plate surrounding the nursery. Is provided with a rectangular block attached to the outside.

The structure and operation of the means of the present invention will be described below.

The inventors of the present invention focused on the fact that spiny lobster is a different ecology than other seafood, and studied the ecology, and obtained the following findings.

(1) Ise shrimp become juvenile shrimp from Puerlus, and this juvenile shrimp is bred and grown into adult shrimp. By the way, in Puerlus, Amakusa (seaweed) is traditionally said to be a natural epiphyte of Puerlus, but because the growth situation of seaweed in the sea is not always appropriate for Puerlus, The settlement rate is low, and the collection of feed organisms is not sufficient, so that even juveniles are rarely reared.

(2) In the rearing from Puerlus to adult shrimp, as long as these feed organisms are present during the rearing period, it does not require much movement as with other seafood.

In short, the Ise shrimp reef has a high Puerle's epidemic rate, is not preyed on by external enemies, and is a structure that supplies the required amount of feed organisms during the rearing period, that is, it is distributed so as to be close to the natural state suitable for Puerle's settlement. The flocked body was attached to the frame, and a structure for collecting overfeeding feed organisms was created, and along with this, a nursery consisting of spherical structures such as stones was formed around the lower part of the frame. The structure is required.

The present invention was established based on the above findings.

Hereinafter, the present invention will be described in detail with reference to the drawings.

FIG. 1 is a perspective view of a nursery reef according to one embodiment of the present invention, FIG. 2 is a partially cutaway perspective view of the nursery reef of FIG. 1, and FIG. 3 is a base of FIG. It is the top view seen from the upper part of a stand.

Reference numeral 1 is a seedling device, 2 is a spherical structure, 3 is a base, 4 is a rectangular block, 5 is a frame body, 6 is a flocked body, 7 is a holding plate, 8 is a window opening plate, 9 is a slit, 10 is a pillar, 11 is a pillar insertion opening, 12 is a nursery, and 20 is a lobster nursery reef.

First, the Ise shrimp nursery reef 20 in FIG. 1 is a seedling device 1 consisting of a frame 5 on which a hair transplant body 6 is attached on a base 3, and a nursery 12 and a nursery 12 at the bottom of this seedling device 1. It has a structure in which a rectangular block 4 is provided so as to surround the nursery 12 from the periphery.

The seedling collecting device 1 is composed of a frame 5 having a rectangular shape and having openings at the upper and side portions thereof. The reason for using such a frame 5 is that the feed organisms floating in seawater are opened through the opening. Because it can be guided inside. The frame 5 is made of a synthetic resin plate or fiber such as fiber reinforced synthetic resin or nylon synthetic resin having excellent corrosion resistance and strength resistance.

The shape is a cube, a rectangular parallelepiped, etc., one of the columns 10 supporting the frame 5 is attached to at least four corners of the lower part, and the other is fitted into the column insertion port 11 of the base 3. Is provided.

Further, the flocked body is attached to the fixing member such as a fibrous body, a rod-shaped body, a plate-shaped body or the like from the upper part to the lower part of the frame body 5 at predetermined intervals.

Both the flocked body and the member for fixing the flocked body are preferably composed of those having the same physical properties as the frame body 5, and the structure of the flocked body has various shapes such as a strip shape and a shape similar to Amakusa. Examples thereof include, but are not particularly limited to, those having a shape similar to Amakusa are preferable.

Further, the attachment method is preferably such that rod-like bodies arranged at a constant interval in the upper opening of the frame body 5 are attached in a shape similar to Amakusa, but the present invention is not limited to this, and it is not limited to this. Any structure may be used as long as the rate is increased. The nursery 12 is a spherical structure such as a crushed stone between each pillar of the pillar 10 that supports the frame body 5 of the seedling device 1 from the bottom and in the periphery thereof.
It has a structure in which a large number of 2 are arranged, but in the case where a space is provided in the central part, the feed organisms guided from the seedling collector 1 mainly gather in the space and the juveniles can prey on the feed organisms. In addition, it is preferable that the space between stone-shaped structures such as the cobblestone 2 can be a place where the shrimp can rest and live comfortably. The nursery 12 is provided so as to be surrounded by the angular block 4 from the periphery thereof. This is because the seedling device 1 and the nursery 12 are firmly fixed even if they receive a flow of seawater or the like.

Further, a window opening plate 8 is provided on the entire outer surface of the rectangular block 4, but the window opening plate 8 and the rectangular block 4 can cause a large amount of overcurrent in the flow of seawater, It has the effect of collecting feed organisms around the reef 20.

In addition, when the nursery reef 20 is used for a long period of time, sand and mud are accumulated on the nursery ground 12, so a slit 9 is provided near the center of the base 3, and the deposit is discharged from this slit 9. It is designed to prevent accumulation.

<Effects of the Invention> As described in detail above, the Isebi nursery reef according to the present invention is a seedling device comprising a box-shaped frame body having a hair transplant body mounted on a base having a slit near the center. And a nursery consisting of a pillar structure supporting the seedling device provided at the lower four corners of the seedling device with a spherical structure arranged between each pillar, and a window opening plate surrounding the nursery. It is characterized in that a rectangular block attached to the outside is provided.

Therefore, since the seedling collecting device is equipped with a synthetic resin flocked body in a new state naturally, the engraftment rate of puerulus is increased, and further the pierced puerleus is protected by the flocked body and is damaged by external damage. Can be prevented.

In addition, a rectangular block is provided in the lower part of the seedling device, and the arrangement of the window opening plate and the rectangular block on the outside of this block causes a lot of overflow, so that it is possible to enhance the collection of feed organisms, The flocked body provided in the seedling collection device further promotes its reproduction.

In addition, since there is a nursery school where many spherical structures such as stones are arranged below the seedling collection device, the juvenile shrimp transformed from Puerlus in the seedling collection plant will move and settle in the nursery, and the optimal shrimp It becomes a habitat and becomes a prawn.

Further, since the Isebevi nursery reef is provided with a base having a slit under a spherical structure such as a stone stone, deposits such as sand and mud are discharged from the slit, and it can be used for a long period of time.
