PROBLEM TO BE SOLVED: To provide a fish-luring material capable of easily propagating undersea plants, such as zostera marina, at a low cost, by fishing with ground baits, and further capable of improving the undersea environment so as to accelerate increase of aquatic organisms. SOLUTION: This fish-luring material contains at least undersea plant propagules. When the fish-luring material thus prepared is used in fishing, such as angling, the undersea plant propagules are underseas seeded together with the ground baits, then spontaneously descend, and land on the seabed. Soon, the undersea plant propagules germinate and grow so as to raise the aquatic organisms and further to create seaweed beds which improve the undersea environment. Further, the undersea plant propagules are coated with a soil conditioner, so that a specific gravity, weight, and critical Shields number of the undersea plant propagules are increased. Therefore, the propagules descend at a high sedimentation velocity and are easily buried in the seabed, and further the coated soil conditioner is changed into a base for growing the plants and a fertilizer so as to make the undersea plants stably germinate and grow.
