Abstract : The method concerns a method whereby Sea creatures of the genus Medusa (sea nettles, jellyfish) are driven to the surface of water by exposure to acoustic waves at frequencies from about 2 to about 3.2 kilohertz. The creatures may then be identified and gathered by net, centrifugal separators, or other means, and disposed of.
