Description

【考案の詳細な説明】 産業上の利用分野 この考案は魚礁に関する。[Detailed explanation of the idea] Industrial applications This idea concerns fish reefs.

従来技術 従来の魚礁は、コンクリート、鋼材、合成樹樹
あるいは木材等を素材として組立てた剛構造の構
造物であつた。このために魚礁を沈設した海域に
おいて曳網等による網漁業を行なうと魚礁に網等
の漁具が絡まり、操業が渋滞したり、器物が損傷
し問題が多かつた。Prior Art Conventional fish reefs have been rigid structures constructed from materials such as concrete, steel, synthetic trees, or wood. For this reason, when net fishing using seine nets was carried out in sea areas where fish reefs had been sunk, fishing gear such as nets became entangled with the reefs, resulting in many problems such as traffic jams and damage to equipment.

考案の目的 この考案は上記事情に鑑みなされたものであ

く、網漁業と共存することができる魚礁を提案す
るにある。Purpose of the invention This invention was created in view of the above circumstances. The purpose is to propose a reef that can coexist with net fishing without getting caught in fishing gear such as seine nets.

考案の構成および実施例 以下、図示する実施例により説明する。Structure and implementation examples of the idea The present invention will be explained below with reference to illustrated embodiments.

殻は滑らかに彎曲している。 In FIG. 1, a fish reef main body 1 has a floating body 2 inside and is pulled upward by its buoyancy, and the lower end of the main body 1 is moored to an anchor 3 with a cable 4 so as to be able to tilt and swing, and the main body 1 and the floating body 2 The outer shell is smoothly curved.

る。 In this embodiment, the fish reef body 1 is formed into a gabion shape by winding FRP (fiber reinforced plastic) strips in two intersecting spiral directions, and the lower end is smoothly curved and tapered. Floating body 2 is made of FRP,
It is fixedly integrated with the upper end of the main body part 1, is a cylindrical hollow shell, and the inside is filled with polyethylene foam.
Its upper end is spherical and smoothly curved.

再び直立の姿勢に戻ることができる。 FIG. 2 shows an example in which a large number of fish reef bodies 1 equipped with floating bodies 2 are moored to one anchor 3 to form a fish reef group. The reef body 1 is pulled upward by the buoyant force of the floating body 2 and is locked to the anchor 3 so as to be tiltable, so that it stands upright when no external force is applied. However, if a seine net gets caught and an external force is applied to it, it will swing, tilt, or fall sideways. In addition, because its outer shell is smoothly curved, fishing gear such as nets and ropes that are caught in it can be easily removed. After the external force is removed, the patient can return to an upright position.

考案の効果 この考案は以上の通りであり、この魚礁は曳網
等の漁具が引掛らないので、網漁業と共存するこ

可能とするものである。Effects of the invention This invention is as described above. Since this fish reef does not get caught in fishing gear such as seine nets, it can coexist with net fishing and enables efficient fishing operations in coastal waters.
