|発明の名称||METHOD FOR PREVENTING SEA URCHIN FROM CRAWLING UP AND INSTRUMENT USED FOR THE METHOD|
PROBLEM TO BE SOLVED: To provide a secure method by which sea urchins are prevented from crawling up leg parts and outer walls of facilities for preventing sea urchins from entering and a simple instrument used for the method.
SOLUTION: The method for preventing sea urchins from crawling up the leg parts and the outer walls of the facilities comprises arranging and fixing circular or belt-like instruments, in which beads rotatable around a thin, hard and round bar as an axis are connected like a string of prayer beads, to the circumferences of the leg parts or the outer walls of the facilities for preventing sea urchins from entering or protection materials attached to them, at intervals through which sea urchins can not craw or to which tube feet of sea urchins do not reach. Connecting beads rotatable around the thin, hard and round bar as the axis like the string of prayer beads provides the circular or belt-like instrument used for the method. Preferably, these instruments are supported or fixed by a plurality of arms radially extended from the leg parts or outer walls or protection materials.
