FISH BED BLOCK AND FISH BED BLOCK FISHING METHOD USING THE SAME
PROBLEM TO BE SOLVED: To provide a concrete fish bed block simulating a natural stone that includes a cul-de-sac-like fish bed structure and a fishing bank culvert structure having a connecting function, and further enabling a fish bed block fishing method using the structure.SOLUTION: A concrete fish bed block 10 simulating a natural stone is configured such that an upper surface 20 and a lower surface 21 are flat, an entire periphery is round, and a predetermined thickness is provided. The fish bed block 10 adopts means for being formed by providing one or multiple cul-de-sac-like fish bed holes 22 in a peripheral one end; bringing a small water passage hole 23 for enabling a water flow to flow in an innermost part of the fish bed hole 22 into communication therewith; providing multiple positioning protrusions 24 to the lower surface 21; and providing a fitting recess 25 having a shape with the protrusions 24 fitted therein on the upper surface 20.SELECTED DRAWING: Figure 1
【課題】袋小路状の魚床構造と連結機能を有する漁礁暗渠構造を備え、さらにその構造を利用した魚床ブロック漁法ができる自然石を模したコンクリート製の魚床ブロックの提供。【解決手段】上面２０と下面21が扁平で周縁全体が丸みを帯びた所定の厚みを有する自然石を模したコンクリート製の魚床ブロック１０であって、該魚床ブロック１０は、周縁の一端に１または複数の袋小路状の魚床穴２２を設けると共に、該魚床穴２２の最奥部に水流が流入する小形の通水孔２３を連通し、下面２１には位置決め用の複数の突起部２４を設け、上面２０には該突起部２４が嵌め込まれる形状を有する嵌め込み凹部２５を設けて成る手段を採る。【選択図】図１
