PROBLEM TO BE SOLVED: To provide a fishing bank made of bamboos in place of a fishing bank made of concrete or a fishing bank made of steel in order to artificially and effectively provide a living environment for fishes. SOLUTION: This artificial fishing bank made of the bamboos is obtained by using the bamboos as a structural material, lengthwise and breadthwise connecting or fixing the bamboos and thereby forming the bamboos into a planar or a three-dimensional fishing bank. Openings for filling water are provided in the interior of the bamboos in order to maintain the strength of the bamboos themselves at the bottom of water and lose the buoyancy. The openings can be utilized for injecting a feed, etc., and raising the fish gathering ratio. Furthermore, the fish gathering ratio and egg-laying ratio can be more raised by wrapping twigs of the bamboos with leaves and twigs of Japanese cedars with leaves in a laver net, etc., and fixing and installing the wrapped twigs, etc., in the three-dimensional structure. A surface layer floating type, a midwater floating type or a water bottom fixed type can be selected as a method for installation.
