CROWN-OF-THORNS STARFISH ATTRACTANT, METHOD OF ATTRACTING THE SAME AND TRAP FOR CAPTURING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a crown-of-thorns starfish attractant that has the action to attract crown-of-thorns starfish and round up them thereby safely and efficiently capturing and exterminating them or by disturbing their eating behaviors and controlling them thereby contributing to the preservation of corals, provide a method of attracting the starfishes and the traps for capturing them. SOLUTION: The objective crown-of-thorns starfish attractant includes long- chain unsaturated fatty acids of 12-24 carbon atoms or their derivatives or betains as active ingredients and they may be carried on a sustained release support, for example, agar. In the method of attracting the starfishes, the attractants including long-chain unsaturated fatty acids of 12-24 carbon atoms or their derivatives or betains as active ingredients may be individually employed or in combination, for example ropes impregnated or coated with the attractant are placed in the sea bottoms or within the traps 110.
