SOLUTION: The objective jellyfish excluder comprises a cylindrical casing 1 of a cylindrical body 11 that is closed at the uppermost end and the screw conveyer 2 that is contained rotatably inside the cylinder 11. The lowermost end of the cylinder 11 is opened to form the sucking opening 13 and the exclusion opening 14 is formed on the side wall on the uppermost side of the cylinder 11. The screw conveyer 1 is rotated at a high speed with the motor 3 and the jellyfishes K together with fishes in the fishing net are sucked from the sucking opening through the casing 1 and excluded from the exclusion opening 14. As they pass through the casing 1, the jellyfishes K are crushed with the screw blades 22 and conveyed.
