PROBLEM TO BE SOLVED: To provide a trapping device capable of effortlessly trapping small crabs and fishes entering therein in search of food by submerging the trapping device for trapping the small crabs and fishes, in sea water with rocks.SOLUTION: The small crab/fish trapping device is formed by creating a cube with a vinyl-coated wire and covering the six surfaces with a net formed of a strong vinyl-based string. The four surfaces of the cube are configured to have rotationally openable/closable lids. Lines attached to the upper part of the respective lids are passed from the body inside to a ceiling part and rewound by a take-up unit. When the lines are loosened to submerge the trapping device in water, the lids are opened. When the lines are rewound, the lids are closed, with small crabs and fished stored therein, and, when the lines are rewound further, the trapping device body is recovered to the footing.COPYRIGHT: (C)2014,JPO&INPIT【課題】岩のある海水の中に小蟹小魚を捕獲する捕獲具を入れて餌を求めて入ってきた小蟹小魚を無理なく捕獲できる捕獲具を提供する。【解決手段】ビニールでコーティングした針金で立方体を作り、6面をビニール系の強い糸で製作した網で被った小蟹小魚捕獲具であり,立方体の4面に回動自在に蓋が開閉できる構造にして,蓋の上部に取り付けた糸を本体内から天井部分を通し、巻き取り器で巻き取る形とした。糸を緩めて捕獲具を水中に沈めると蓋が開き、糸を巻き取ると小蟹小魚が入ったまま蓋が閉まり、さらに巻き取って捕獲具本体を足元まで回収できることを特徴とする。【選択図】図1
