Description
【発明の詳細な説明】
本発明は、こんぶなどの海そう類の養殖用魚礁に好適な
魚礁の形成方法を提供しようとするものである。DETAILED DESCRIPTION OF THE INVENTION The present invention aims to provide a method for forming a fish reef suitable for culturing seaweed such as kelp.
以下、図面を参照しながら、本発明の１実施例の詳細を
説明する。Hereinafter, details of one embodiment of the present invention will be described with reference to the drawings.
１は、本発明に使用される魚礁用枠で、その構成は、耐

による横杆１Ｂを所定間隔をもって張設すると共に、上
面には石塊投入用の開口部１Ｃが形成されている。Reference numeral 1 denotes a frame for a fish reef used in the present invention, and its configuration is such that the frame 1A is formed into a triangular pyramid shape or a truncated triangular pyramid shape with round bars made of steel material that has not been subjected to corrosion-resistant treatment. Horizontal rods 1B are stretched at predetermined intervals, and an opening 1C for introducing stone blocks is formed on the upper surface.
１Ｄは補強用縦筋で、上記横杆に対して直交するよう添
着されている。1D is a reinforcing longitudinal reinforcement, which is attached perpendicularly to the horizontal rod.
そこで、魚礁の設置を所望する海底１Ｅに上記魚礁用枠
を設置し、上記開口部を利用して石塊１Ｆを投入する。Therefore, the fish reef frame is installed on the seabed 1E where it is desired to install a fish reef, and the stone blocks 1F are introduced using the opening.
本発明のものは、上述の如く構成されているから
Ａ、海岸、の設置が、枠を入れてから石塊を投入するか
ら、重機などを使用することなく、作業性に富む。Since the device of the present invention is constructed as described above, the installation on the shore A is easy because the stone blocks are put in after the frame is put in, so there is no need to use heavy machinery.
Ｂ０石塊間にはすき間が出来るから、こんぶなどが付着
成長するほか、魚のえさになる小動物が住みつく。There are gaps between the B0 stones, so not only do kelp and other things grow attached to them, but also small animals that serve as food for fish live there.
Ｃ１枠に耐蝕性がないから、数年たつと海水によって腐
蝕し始め、形状が変化し、内部の石塊も周囲にくずれる
。Since the C1 frame is not corrosion resistant, after a few years it begins to corrode due to seawater, its shape changes, and the stone blocks inside it collapse into the surrounding area.
このため、こんぶなどがつきやすくなる。For this reason, it becomes easy for kelp etc. to stick to it.
Ｄ、三角錐台状あるいは三角錐状に構成されているから
、表面積が大きく、効率の良いこんぶなどの付着が期待
できる。D. Since the structure is shaped like a truncated triangular pyramid or a triangular pyramid, it has a large surface area and can be expected to efficiently attach kelp etc.
Ｅ、養殖目的のほか、海岸の浸蝕を防止する効果をも有
する。E. In addition to being used for aquaculture purposes, it also has the effect of preventing coastal erosion.
