PROBLEM TO BE SOLVED: To provide a method and apparatus for symbiotic aquaculture of loaches and aquatic edible plants in which the aquaculture and the cultivation can efficiently be made while making the loaches coexist with the aquatic edible plants.SOLUTION: Multiple aquaculture outer cases 1 of loaches are arranged and placed horizontally or vertically, and the piping 2 for ground water and the piping 3 for cold warm water are laid, respectively. The piping 3 for cold warm water is placed in the center of the inside where palm shell fibers 6 are put properly while colander inner cases 8 are suspended with S-shaped wire 5 in the aquaculture outer case 1. The colander inner case 8 is installed in a proper height position from the bottom of the aquaculture outer case 1 with the S-shaped wire 5. Multiple roots of the aquatic edible plant 8 such as the Japanese parsley are made into soft stiffness and planted. The piping 2 for ground water is directly attached to the center of the aquaculture outer case 1, and the center of the palm shell fibers 6 are installed from the entrance to the outlet of the box.SELECTED DRAWING: Figure 2【課題】ドジョウ類と水生食用植物を共生させつつ効率よく養殖並びに栽培することができるドジョウ類と水生食用植物との共生養殖栽培方法及び装置を提供する。【解決手段】ドジョウ類の養殖用外箱１を横置き又は縦置きに複数並べ、地下水用配管２、冷暖水用配管３をそれぞれに配管する。冷暖水用配管３は養殖用外箱１にザル型中箱８をＳ字型針金５で宙吊りにされた中に椰子殻繊維６を適度に入れた中の中心に入れ、ザル型中箱８はＳ字型針金５などで養殖用外箱１底部から適度な高さ位置に設置する。セリなどの水生食用植物８の根をふんわりとした固さにして複数植え付ける。地下水用配管２は養殖用外箱１の中心に直接取り付け、椰子殻繊維６の中心を箱の入り口から出口に向かい設置する。【選択図】図２
