【発明の詳細な説明】
〈産業上の利用分野〉
この発明は、イセエビの産卵と着底を促すようにしたイ
セエビ用魚礁に関するものである。[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to a reef for spiny lobsters that promotes spawning and landing of spiny lobsters on the bottom.
〈従来の技術及びその間量点〉
イセエビは主として日本の太平洋岸にすみ、美味である
ことから食用としてひろく人々に知られている。そして
夜間に活動するが、岩礁に好んですむ、ところで、この
イセエビは夏期は産卵期に当るために禁漁にして保護さ
れるので、漁期は１０月から翌年５月までであるので、
単に姿や色が兄事という理由のみならず、存在それ自在
が少ないために高価なものとされでいるのである。<Prior Art and Quantity Points> Spiny lobsters mainly live on the Pacific coast of Japan, and are known to many people as edible because of their delicious taste. They are active at night, but prefer to live on rocky reefs. By the way, this rock lobster is protected by being closed to fishing during the summer when it spawns, so the fishing season runs from October to May of the following year.
They are considered expensive not only because their appearance and color are similar to each other, but also because they have little freedom in their existence.
ところで、このイセエビは前記のように岩礁にすみ夜間
に行動するために、これを捕獲する方法としては、夕方
＠礁の周りに刺網を張り、早朝に採るというのが一般で
あり、従来はこのイセエビを強制的に一箇所に集合せし
めたり、またはイセエビ専用の魚礁も存在しなかった。By the way, as mentioned above, this spiny lobster lives on rocky reefs and is active at night, so the common way to catch it is to set a gillnet around the reef in the evening and catch it in the early morning. There was no way that these spiny lobsters were forced to gather in one place, nor did there exist fish reefs exclusively for spiny lobsters.
したがってイセエビを定着させる技術もなく、その結果
がイセエビを高価なものとしていたのである。Therefore, there was no technology for establishing spiny lobsters, and as a result, spiny lobsters became expensive.
本発明者らは、これらの事情を考慮しで、従来から行な
ってきた人工魚礁の研究・開発と関連して、特にイセエ
ビに適する魚礁の開発を行なうべく、イセエビが生息す
る海底、特に岩礁の形状及び環境を調査した結果、この
発明をするに至ったのである。Taking these circumstances into consideration, the present inventors, in conjunction with the research and development of artificial reefs that have been carried out in the past, aimed to develop a reef particularly suitable for spiny lobsters. As a result of investigating the shape and environment, we came up with this invention.

すなわち、この発明にかかるイセエビ用魚礁は、略半球
ドーム型に形成したブロック本体の壁面に多数の凹部を

である。Means for Solving the Problems> That is, the reef for spiny lobster according to the present invention has a large number of recesses formed on the wall surface of the block main body formed into a substantially hemispherical dome shape, so as to encourage spawning and landing of the spiny lobster on the bottom. This is what I did.

This is a drilled hole. 3 is a recess formed in the wall surface of the block main body. When the recess 3 is formed only on the outer surface of the block main body as shown in FIG.
When it is formed not only on the outer side but also on the inner side of the block body 1 as shown in (b), it is formed in the shape of a through hole by penetrating inside and outside the wall surface of the block body 1 as shown in (c) of the same figure. In this case, if the hole is made with a bottom as shown in (a) and (b) of the same figure, or if the diameter of the inner part is made larger than the opening part as shown in (d) of the same figure, or if the hole is made with a bottom as shown in (d) of the same figure, the recess 3 There are various configurations, such as cases where the diameters of the openings are the same or different. Further, the shape of the recess 3 is not limited, such as when it is rounded or rectangular (or square) as shown in the figure.

After it has been turned into a turf, this block body 1 is used to reminisce. That is, when adult spiny lobsters live in the recess 3, they will spawn there. After spawning, the young spiny lobsters turn into stems and evacuate, inhabiting the recess 3 corresponding to their own body and growing there. As it gets longer, it feels cramped in the concave part 3 where it originally lived, and moves to another comparatively large four part 3. Eventually, it becomes conscious there and gradually moves to the larger concave part 3. It will become. And that's where you will grow.
ここでブロック本体１を半球ドーム型に形成したのは、
イセエビが夜行性であることに鑑みて、可及的に生活環
境を暗くするためである。Here, the block body 1 is formed into a hemispherical dome shape because
Considering that spiny lobsters are nocturnal, this is to make their living environment as dark as possible.

できるのである。It is also said that the biggest enemy of spiny lobsters is octopuses. However, moray eels are said to be the enemy of this octopus, and moray eels do not consider spiny lobsters to be harmful.Therefore, in the block body 1 according to the present invention, the concave portion 3 is formed into a large rectangular shape, and a portion where moray eels can live. By encouraging the moray eel to prey on the approaching octopus,
