PROBLEM TO BE SOLVED: To provide a floating fish reef simple in structure and capable of improving swarm efficiency by securing a large area of a shadowed portion serving as a hiding place for fish.SOLUTION: The floating fish reel 10 is constituted by connecting a large number of small floating bodies 1 in rosary shape through a long rope 2, folding the connected body zigzag every predetermined length so as to be arranged in almost rectangular shape, and connecting the respective small floating bodies 1a, 1b on both sides located at the respective folded portions, using two ropes 3a, 3b so as to penetrate the small floating bodies 1a, 1b, to form an almost rectangular planar floating reef body 4. The upper ends of mooring ropes 5 are connected to four corners of the planar floating reef body 4, and an anchor 6 is connected to the lower ends of these four mooring ropes 5.【課題】簡易な構造で、かつ、魚類の隠れ場所となる陰影部分の面積を大きく確保して、蝟集効率を向上させることができる浮魚礁を提供する。【解決手段】この浮魚礁１０は、多数の小浮体１を１本の長尺のロープ２を介して数珠状に連結したものを所定の長さ毎にジグザグ状に折り返してほぼ矩形形状に配置するとともに、各折り返し部分に位置する両側の各小浮体１ａ，１ｂを貫通するように２本のロープ３ａ，３ｂにより連結してほぼ矩形形状の面状浮礁体４を構成し、この面状浮礁体４の四隅に係留索５の上端部を連結し、それら４本の係留索５の下端部にアンカー６を連結して構成する。【選択図】図１
