摘要

PROBLEM TO BE SOLVED: To obtain a substance for promoting the inhabitation of aquatic lives installed with spacing parts having a water passing property, also having a shape having a fitting property, and a function for promoting the inhabitation, excellent in productivity and installation properties. SOLUTION: This substance for promoting the inhabitation of aquatic lives is obtained by installing space parts having a water passing property and shapes of a helical shape 1, a square pillar body, a gourd shape, a pipe shape having a hexagonal cross section, a trapezoidal shape or an almost S-shape, and a fitting property. Further, e.g. the helical-shaped substance 1 is obtained by cutting a waste tire into halves to form a semicircular shape, and fixing these semicircular waste tires with shifting by 45 deg. each. Also, it is preferable to form holes for passing water in the substance for promoting the inhabitation of aquatic lives.
