  • Patent number: 4447978
    Abstract: Fish are captured utilizing a chain reaction of larger fish feeding on smaller fish. A bait-enclosing structure is mounted within a frame, and a first net is provided surrounding and substantially concentric with the bait-enclosing structure. The first net has openings formed therein large enough to allow small fish to insert their heads through the openings in an attempt to feed on the bait and catch their gills on the net if withdrawal is attempted. The assembly is lowered into a body of water, and after a predetermined time period a desired number of fish are trapped within the assembly utilizing a second net surrounding the first net, and then the assembly is raised to the surface. Entrapment may be provided by providing the second net having larger openings than the first net and concentric therewith, so that fish attempting to feed on fish caught by the first net will be caught by the second net.
