この考案は、アワビ稚貝の放流に用いる石詰礁
に使用され、稚貝を石詰礁中の投入して保護する
装置に関する。[Detailed Description of the Invention] (Industrial Application Field) This invention relates to a device that is used in a stone reef used for releasing young abalone shellfish, and that protects the young abalone by inserting them into the stone reef.
（従来の技術）
従来、アワビを増殖する場合、育成センターで
アワビ稚貝を育成し、これを予め投石等によつて
造成された放流場所に投入放流して増殖する、大
規模増殖場事業が一般的に行われている。この場
合、放流方法としては、潜水夫が海底に潜水して
アワビ稚貝を捨石上に放流する方法が多く採用さ
れていたが、一部では海上から稚貝を散布する方
法も採用されていた。(Conventional technology) Conventionally, when breeding abalone, a large-scale breeding farm project was carried out, in which young abalone shellfish were grown in a breeding center, and then the young abalone were put into a discharge area that had been created in advance by throwing stones, etc., and then released and multiplied. This is commonly done. In this case, the most common method of releasing the abalone was for divers to dive to the seabed and release the young abalone shells onto rubble, but in some cases a method of scattering the young abalone shells from the sea was also adopted. .
しかるに、従来の増殖方法では、放流後に稚貝
が捨石表面に密着するまでに波によつて生ずる海
水の流れによつて稚貝の大半が流され、特にアワ
ビ稚貝の単なる放流では魚類に餌をばらまく結果
となり、いずれにしても効率によい増殖ができな
いという問題があつた。 However, in conventional propagation methods, most of the young shellfish are washed away by the currents of seawater generated by waves by the time the young shellfish adhere to the rubble surface after being released. In either case, there was a problem in that efficient multiplication was not possible.

109974号）。(Problem to be solved by the invention) On the other hand, the present applicant provided a plurality of spaces on the outer peripheral surface of the box, while making the input tube (vertical tube) and the ejection tube (horizontal tube) communicate with each other. We have developed and applied for a stone-filled reef for young abalone shells, which is equipped with a protection device for introducing young abalone shells, houses the protection device inside the box, and is filled with stones to improve the propagation efficiency. −
No. 109974).
ところで、上述の石詰礁中にアワビ稚貝を投入
する場合、アワビ稚貝の野性化に応じてアワビ稚
貝が石詰礁から外部へ容易に這い出すことができ
るように、石詰の間〓を比較的大きな寸法とする
必要があるが、他方、、稚貝がある程度野性化す
るまでは宿敵魚類の侵入を防止してこれを餌とす
る魚類から保護する必要がある。 By the way, when putting young abalone into the above-mentioned Ishizume reef, it is necessary to place it between the Ishizume so that the young abalone can easily crawl out from the Ishizume reef as the young abalone becomes wild. It is necessary to make the shellfish relatively large in size, but on the other hand, it is necessary to prevent the invasion of enemy fish and protect it from the fish that feed on it until the young shellfish become wild to some extent.
上述のアワビ稚貝用石詰礁では、投入筒上端開
口については一旦アワビ稚貝を保護装置内に投入
した後はそこからアワビ稚貝の這い出しを考慮す
る必要がなく、これを蓋体等で閉塞しておいても
よい。 In the above-mentioned stone reef for young abalone shells, there is no need to consider the possibility of young abalone shells crawling out from there once the young abalone shells have been put into the protection device, and the opening at the top end of the feeding tube can be closed with a lid, etc. It may be kept closed.
しかしながら、脱出筒の両端開口については、
野性化後のアワビ稚貝の這出性を確保する必要が
あるが、そのまま単に開放するようにすると、宿
敵魚類が開口端から侵入し、稚貝を食べるという
問題が生じる。 However, regarding the openings at both ends of the escape tube,
It is necessary to ensure that the young abalone shellfish can crawl out after becoming wild, but if it is simply left open, there will be a problem that enemy fish will enter through the open end and eat the young shellfish.
この考案は、かかる問題点に鑑み、脱出筒開口
端を塞いでアワビ稚貝を魚類から保護できるとと
もにアワビ稚貝の野性化後に這出性を確保できる
ようにしたアワビ稚貝投入保護装置を提供するこ
とを課題とする。 In view of these problems, this invention provides a protection device for introducing young abalone shells that can protect the young abalone shells from fish by blocking the opening end of the escape tube, and also ensure the ability of the young abalone shells to crawl out after becoming wild. The task is to do so.

旨とする。(Means for Solving the Problems) Therefore, the device for protecting young abalone shells according to the present invention has a structure in which a young abalone shell feeding tube is provided in the vertical direction, and an escape tube extending horizontally is provided at the lower end of the feeding tube in a substantially reverse direction. The escape tube is provided in a T-shape and in communication, and a lid having a predetermined outlet gap is attached to both open ends of the escape tube, and an outlet gap is provided at both ends of the escape tube.'' do.
ここで投入筒の上端開口については特に限定し
ていないが、通常の蓋を開閉自在に又は着脱自在
に設けてもよく、又脱出筒両端開口の蓋と同じ構
の蓋を設けてもよいのは勿論である。 Here, the upper end opening of the input tube is not particularly limited, but it may be provided with a normal lid that can be opened and closed or detached, or a lid with the same structure as the lids of the openings at both ends of the ejection tube may be provided. Of course.
（作用）
本考案においては、脱出筒の両端開口を蓋で閉
塞する一方、該蓋及び脱出筒の両側端部に出口間
〓を設けるようにしたことから、宿敵魚類が投入

又野性化したアワビ稚貝は出口間〓から外部に容
易に這い出すことができる。(Function) In the present invention, the openings at both ends of the escape tube are closed with lids, and the exit holes are provided at both ends of the lid and the escape tube. They rarely invade the
In addition, young abalone shellfish that have become wild can easily crawl out from between the exits.
（実施例）
以下、本考案を図面に示す具体例につ基づいて
詳細に説明する。(Example) Hereinafter, the present invention will be described in detail based on a specific example shown in the drawings.

這い出しうる寸法の間〓に設定されている。 1 to 4 show a device for protecting young abalone shells from being introduced according to an embodiment of the present invention. In the figure, 1
is a feeding tube for young shellfish 9 installed vertically, and an escape tube 2 extending horizontally is provided at the lower end of the feeding tube 1 in a substantially inverted T-shape and communicating with the escape tube 2.
A lid 3 is attached to both open ends of the lid 3, and a predetermined outlet gap 4 extending in the vertical direction is formed in the lid 3. In addition, an outlet gap 5 extending horizontally is provided at both ends of the escape tube 2, and the outlet gap 4, 5 is a gap that allows young abalone shellfish 9, which have become wild to some extent, to crawl out. It is set.
なお、上記投入筒１の上端開口には図示してい

詰礁７内には上記投入保護装置がその投入筒１の
上端開口を石詰礁７上に開口させて収容されると
ともに、石詰８が充填されている。 On the other hand, a stone reef 7 is provided on the bottom frame 6, and the above-mentioned charging protection device is accommodated in the rock reef 7 with the upper end opening of the charging tube 1 opening above the rock reef 7. , stone filling 8 is filled.
次に作用効果について説明する。 Next, the effects will be explained.
上述の投入保護装置を第３図に示すように石詰

石詰８から石詰礁７外に這い出して大きく育つこ
ととなる。 If the above-mentioned feeding protection device is placed in the stone reef 7 as shown in Fig. 3, and the young abalone shells 9 are dropped from the upper opening of the feeding tube 1, the young abalone shells 9 will become wild over time and will no longer become harmful enemies. Once they become inedible, they will crawl out from the input protection device through the exits 4 and 5 into the rock jam 8, and then from the rock jam 8 to the outside of the rock reef 7 and grow larger.
こうしてアワビ稚貝９は野性化して投入保護装

ので、アワビ採取の歩留りが良好である。 In this way, the young abalone shellfish 9 stays in the input protection device until it becomes feral and escapes from the input protection device, and since harmful enemies cannot enter there, it is reliably protected from harmful enemies, and after becoming feral, it can be easily harmed. Since the abalone does not become food for the enemy, the yield of abalone collection is good.
